Avoid using any 90 degree fittings between the tank and pump. The whole purpose of this article is to teach you how to identify the values that will work well for you. Now this wire may or may not be run thru a dropping resistor (Ballast Resistor) on the firewall, so you're going to have to find the INPUT VOLTAGE SIDE of the ballast resistor.Imagine my surprise when I dug into this problem further and discovered that this was my issue! Thanks! Capability Range: Professional At the bottom you'll see AE vs TPS RoC Blanking. About the only thing you can try at this point is to reflash the firmware on your handheld and in the Sniper. Your advice would be appreciated. You are on the right track!Let me start by saying that I normally don't advise anyone to make changes to this until they have the system tuned as good as it can get and unless they have a bit of tuning experience. Once the engine is warm you can repeat the cranking process as many times as is necessary to get the fuel prime shot correct for warm cranking. How did you install the return line to the tank? Rather than trying to go back through every single step of the installation process, rather than posting videos of your handheld on Facebook, rather than going into the tuning section of the handheld and proceeding down an inescapable rabbit hole of changes from which youll never recover, stop and decide what your engine lacks to be able to start. I really would like to replace the intake gaskets. Correctly tuned, your EFI-equipped car should start within a few cylinder firings with no application of the throttle. Need to add fuel pump for required pressure. Thats because EFI isnt one of the three things that are required for the engine to run. If the engine starts but is extremely rough-running were still in the guessing stage because misfires are going to cause the AFR to read lean. Great article. Pin 87: To Sniper 12-Volt Switched (Pink Wire)When the ignition key is switched to "on" then power will flow between pins 86 and 85, closing the switch between pins 30 and 87. 2. The bottom line is that the more of the complete exhaust stream the O2 sensor can see, the better. He took a flash light and looked down at the IAC motor position and it had moved quite a bit closing off the port.Now I had to try this and of course my results were not so lucky. Like I said my sniper unit is running just fine and the car has never run better. MSD recommends non resistor plugs. Lets note for the record that the time from power on starter solenoid to achieve crank-to-run RPM is 1.13 seconds. Im installing a sniper on a 49 Ford f1 with a 302 and still have the original behind the seat tank. Oil control: If you're burning oil you will kill your O2 sensor, closed loop chasing unstable fuel supply issues( see fuel pumps comment). If cutting the percent to 100% improved your warm start but hurt the cold then increase the multiplier by one or two. 1964 Chevy Nova, 383 Stroker, AFR 210 Heads, Ford 9inch w/TrueTrac/3.90 Gears, Powerglide Transmission. A low air to fuel ratio means the mixture is rich. Enjoy! Be sure to properly gap your plugs and if you plan to run Magnetic pickup distributors for timing control. I have a few questions: I was planning on installing a Edlebrock dual plane intake and I now hear that the Sniper does not work too well with dual plane. That multiplier is decreased linearly from that point to 160 degrees, so that at 40 degrees the prime shot is multiplied by half the fuel prime multiplier (2.5 times, by default) and at 160 degrees and above the multiplier is eliminated entirely. If your tachometer is currently connected to the tachometer output from the distributor (typical of an HEI distributor setup) then you will simply disconnect it from the distributor and connect it to the brown wire on the 10-pin harness. Is the fuel pressure correct? Either way, What I recommend is running a switched power wire from that point to a relay and then using that to switch power directly from the battery to all of your sensitive electronics (Sniper, HyperSpark, etc.). i.e., 5x at -40 and 0 at 160. And that from a not-so-shabby original 1.13-second start time. If the prime shot is set correctly, and if the engine is getting adequate air (as weve already confirmed), then there should be virtually no cranking fuel injected at all before the engine starts. Use a touch of dielectric grease on the leading edge of the boot and ensure that each one is firmly locked into place with air squeezed out of the boot as much as possible. Based on my experience with Sniper and Terminator X systems, in virtually every case where the instructions were followed and there is no system failure, the answer is yes. Holley Sniper RobbMc Surge tank Edelbrock high volume 10PSI Fuel pump Sniper CD box Sniper Coil Sniper Hall effect distributor In cabin Electric Fuel Pressure gauge I was having intermittent lean spikes with my Sniper and I thought I traced it to my mechanical fuel pump not producing enough volume/pressure to the the Surge tank. Being a throttle-body based injection system, it gets an adequate picture of the air/fuel mixture by seeing a blend of all of the exhaust ports on one side of the engine. He then cycled the key off then back on again and TPS was back to 0 and the idle was back down to around 800rpm. Extending wires with too small of a wire gauge will also result in the same damage. :-). I've gone through all the steps and cannot seem to solve the problem. A key at the top of each log shows the signals associated with each color. There is really no room for error on this. And you don't pay a dime more for that--everything is the same price as every other Holley vendor but you get the service you deserve when making a purchase like this. At least not right away (after time-delay set in relay). 2023 HOLLEY PERFORMANCE PRODUCTS, INC. ALL RIGHTS RESERVED. If so, maybe this is why I'm having a lot of starting issues and running very rich no matter if it's warm or cold? But you don't mention fuel pressure at the inlet. Default values on these are 150% and 5, respectively. Try cranking immediately upon key-on--before it has a chance to prime. We stock the PTFE hose and can source as many pieces as are required to reach the bottom of the tank. I have it disconnected to flush any debris out.Thank you. Bolt-on carburetor style EFI for your classic car or truck. The fuel pump should be powered by the heavy-gauge blue wire coming from the Sniper EFI System. If you free dumped it in the top, it will aerate and foam up the fuel. You're not running your EFI system without a gauge are you? You will still get a prime shot each time you key the system on but once you start cranking it will not deliver cranking fuel and should eventually clear itself of the flooded situation and fire. The resulting O2 sensor failure is damaged not defective. Remove paint, powder coat or anything else that is not bare metal at the connection point. I'm all eyeballs! Do you see an issue with this? Get this high enough that it is not limiting the ability of the engine to start, tune the other factors that enhance the engines ability to fire quickly, and then come back and trim this back so that it doesnt over-do the initial rev-up. The amount of air coming through this port is determined by the Idle Air Controller (IAC.) From what I read it should not be installed vertically? Cranking fuel lets us compensate for that drop in pressure. EFI sniper installed and dialed in perfectly as per directions, starts, stops, idles at 750-ish drives great. EMI is what wipes out all the electronics. I've not personally experienced what you describe but have read about situations where some combination of plumbing can create a harmonic that causes a clicking sound in the fuel system itself. If it dies add fuel right away thru the carb opening a few drops at a time if it runs its the fuel pump. Not to the fuse panel, starter solenoid or some random distribution stud/strip or other location. Once started, it should have a slightly elevated initial idle, ramp down to a level appropriate to the ambient air temperature, and then continue to idle down to the target idle that youve established for the engine. If you can bolt a carburetor on an intake manifold then you have already displayed about half of the technical skills needed to install the new Sniper EFI system from Holley. It needs the tip pointed down at least 10 degrees from horizontal and at least 15 degrees from vertical I prefer about a 45 degree angle from horizontal. I am running a wet exhaust with O2 sensor plates. Hard starting cool but starts easy when hot. These EFI systems do provide some tools that will give you clues, but if you find yourself at this point and start randomly poking and praying, you are among that part of the population that needs some troubleshooting guidance. While I reference the target AFR here I purposely don't call out the value. Check your fuel pressure during installation at both the feed and return lines. Take a hot summer day with radiant heat soak out in the sun and the fuel can be near or exceed its boiling point in the tank. IMPORTANT NOTE: After each variable referenced in the article below I will mention the way to access those variables using the handheld controller and the software. Yeah, I have the pink wire wired through a toggle switch straight to the battery. This is the crank-to-run RPM. May 23, 2022. Not perfect but not bad. to zero, but I think you'll find that you will stall. There are just turn downs after the electric cut outs. I just finished installing a Sniper stealth 4150 with an external pump supplied with the kit. Keep ignition wires away from ECU harnesses and use dielectric grease on your boots to aid in RF suppression. When you remove a spark plug is it bone dry or dripping wet? Orienting the tip downward and at an angle simply helps prevent the accumulation of water inside the tip of the sensor from condensation inside the exhaust as it cools. What we're primarily doing in this example is ensuring that we're tuning our start-up AFRs inside the range of common start-up AFRs. But I have never heard of anyone else who has had success doing this. Does it matter if O2 sensor goes in drivers side with true duals?Thanks for spending your time helping us weekend mechanics. Probably 3-4 seconds, and rich after it does fire. Exactly. The fuel pump should turn off after 5 seconds until the motor is started. Cheers Darren. *Possible delays due to Covid-19 click for more information. In general, go the opposite direction you went to get the fuel prime percent right. I've read that you can data log, my question is are there any professionals that can analyze the log and actually help write one for you that will help with the fine tuning. Your thoughts?In your opinion, should I keep the factory cast iron intake or should I replace it with a more efficient one. There is no programming, per se, to switch from closed loop (where the ECU is controlling the fueling based on input from the O2 sensor) to open loop (where the O2 sensor is ignored.) Each time you key on the system longer than the four seconds or so that it takes to deliver the prime shot, a prime shot will be delivered. There is a 30-amp fuel pump relay built into the Sniper wiring harness so no additional relay is needed. Great work! And I've helped my share of folks with fuel pumps in empty gas tanks. Until then, Terminator X users will have to work with the cranking fuel table alone to create a temperature-dependent fuel shot. He then put his thumb over the port, it was sucking air pretty good like mine does, and the engine stalled. In fact, MOST of the points on the fuse block don't do that! Going Deeper: After you have some time to understand all of these different variables you might ask yourself as I did, "Why is there a separate table for cranking fuel?" Hi Chris,Thank you so much for your quick response to my query. offer easy plug-and-play And the time from starter engagement to achieving crank-to-run is well under a secondan improvement of roughly 33%. First, it is fake news that EFI doesn't like big cams. what is the proper air/fuel ratio for a sniper on a ford fe 352? Don't hesitate to call, nights and weekends included.). :-) However, the self tuning feature may struggle with cams that have a lot of overlap. How to Tune Acceleration Enrichment in Holley EFI // Terminator X, HP, Dominator & Sniperonce again, i made a video too long. My question is if both of my fuel pumps are wired from relays to my rocker panel where does the blue fuel pump prime wire connect or would you just not use it altogether. Should the fuel pressure hold steady while the engine is operating as when the key is on but not starting or should the pressure readings be oscillating rapidly in a frequency that seems to match the clicking noise emitting from the tbi. Copyright 2017 Cyberspace Automotive Performance, Inc. All Rights Reserved. Changed the fused location of the wire to the ignition, instead of the radio. Why? Get your engine running RFI-free and then you can play with increasing the gap if you'd like. Increase that to 15 to start. In a nutshell, you do the following:1. Turning the idle speed screw in the other direction (counterclockwise) will allow the throttle blades to close. I hope to do more articles similar to this so stay tuned! Activate Advanced Tables2. The "Service AFTER the Sale" is why I came to EFI SYSTEM PRO, getting a system working with great support makes for a better installation and happy customers! Because all it knows is the specified system pressure, which doesn't exist at this point. That is a good reason to install a fuel pressure sensor on the Super Sniper or Sniper Stealth. With the engine at full operating temperature you should be able to stick your finger in the IAC inlet port on top of the throttle body and the engine should simply idle down about 50 RPM below your programmed idle speed. Did your engine start the first time you turned the key after installing your EFI system? Had issues so Im now going with the Holley in tank pump. Is the sniper compatible with my distributor? And the less correction you do until you understand that---the better! Maybe Holley will add Fuel Prime Multiplier to Terminator X later. features . Is that an expectable by-product of adding this relay? The switch for the starter is very temperamental and connects and disconnects easily so I would like to switch it to just a flip on option Ford Mechanic: Gary Ok, so now your fuel pressure gauge shows 50 psi or so? But I strongly suspect that is not the case. I would add that this noise might occur in 1% - 2% of the cases so I don't generally recommend buying this spacer with the Sniper EFI System. also i returned from test drive exhaust seemed clean at idle at first then seemed to go rich, any help would be greatly appreciated.Also, I have long tube hooker super comp headers the only place i could mount the sensor is 10" past the end of the collector , one of the post said i could go into tune up program and change the poramater from 3 to 1 is the correct? Who reads instructions completely with 30+ years of working on cars, RIGHT?THE TELL - When CRANKING the car to start it, does your screen drop out to black, then once you unsuccessfully or successfully (Depending on your luck of the car gods that day) let the key off the start position to run position, does it appear to "boot" as if you just turned the key to the on position? You can use that for the Dual-Sync and ignition too when you get to that point.Running the O2 sensor on a single side of the dual exhaust works fine. A throttle linkage extender and a progressive linkage kit. Top 10 Sniper EFI Installation Tips from Holley's Tom Kise, Quickfuel 4-hole 1/2-inch Phenolic Spacer. Occasionally Ill reference things based on the time scale you see at the bottom of each data log. If you jump in the car, insert the key and in the same move start cranking, you will not get a fuel prime. Now were getting there. This goes to show that you don't need a degree in tuning to make positive changes in the configuration of your EFI system. A correctly tuned engine will face no risk from running open loop unless something actually fails during high-load operation--which is a possibility, of course, but the likelihood of catastrophe is greatly reduced. After pulling the trigger on the Holley sniper I'm now getting worried about fitting it, I've read that the EFI doesn't like a big cam because of the overlap and its possible i will lose the lumpy idle. These settings will be instrumental to a fast start. Ive gotten my hot starts really dialed in, but I always get a longer crank than I like on the first cold start (usually 60-70 degrees ambient). Find a lower price anywhere and we'll beat it by 5%! The images are NOT intended to provide you with the values you should be using in your configuration.

Full product line and accessories at excellent pricing. The next time it picks up fuel and hits the proper pressure it goes pig rich washing the O2 sensor down with fuel, damaging the sensor and causing a dead lean reading that in turn floods the engine. The Del City Time Delay Relay is pinned just like a normal relay. Can I lower it for this purpose? Much appreciated! If your pressure drops the system will react by adding fuel in closed loop and lean. Featured Products Sniper EFI $7.07 - $2,457.95 471 Products View Parts author Staff Writer 1711 Posts An Article About Video tech Sniper EFI Videos Sniper EFI Tech Sniper EFI sniper Installation Does pressing the throttle slightly allow the engine to start. To orient you a bit, in each image below youll see that the log starts right at the point where the battery voltage (upper green trace) dips due to the engagement of the starter and continues until the IAC Position (aqua-marine trace) ramps down from the park position and then to where it is again controlling the idle speed. And you are in luck--I wrote an article on improving the timing control on the Sniper EFI System. Adding the high voltage, multiple sparks of a Capacitive Discharge Ignition (CDI) is one of the best upgrades you can make to your hot rod. Holley Sniper EFI Check Latest Price. Is a tremendous volume of fuel sprayed into just one barrel?

Starts & immediately dies. Capability Range: Advanced If I start the car cool and dont touch the gas the engine will crank and crank and never fire. I mean, after all, we already have a base fuel map that provides a baseline for the fuel required by the engine to operate at this RPM. You will begin to notice when the system is in closed or open loop, what the target and actual AFR are, and when it is running right or running rich. Many of these are completely normal with EFI. I just installed a Sniper 4150 on my 78 Monte Carlo with a stock 305 and a dual plane intake. If you turn the ignition off and back on, & crank it, it will start & die again. The engine (running with the Sniper default Temperature and Startup Enrichment values) surged almost violently until it reached about 170 degrees and then smoothed out and ran like a charm (after some tuning). Nor can I really recommend that you split it as I have. No timing control. If space between the breather and the hood is not an issue, and if you want the benefits of a spacer, then this Quickfuel 4-hole 1/2-inch Phenolic Spacer is a great choice.

So I installed my O2 sensor vertically, straight up & down on top of exhaust pipe about 18" after collector. Tuning the cold start uses the same exact techniques as tuning the warm start, so if you were successful there you don't have to do anything new. From there it is a slam dunk. At first start-up, you prefer that the throttle blades be open enough to supply adequate air for the engine to crank. Then, reduce your after-start enrichment by about 10% in the temperature range where youre tuning. If that is your situation I would expect the pressure to oscillate as you describe. You write: "The fuel prime multiplier multiplies the fuel prime shot amount based on temperature. Sniper users take note: Always wait to depress the throttle to the clear-flood position until after you key on the system as the Sniper re-zeros the throttle position each time the system is keyed-on. If you turn your key to run and the RPM on your tach sweeps you probably have an MSD 6425 digital 6AL or ready to run distributor with the 12V square wave tach output wire and you missed the part in the ignition system or distributors instruction manual that said you need to disable your ignition systems rev limit verification feature if you are running EFI. If the switch has an engineered dead spot between run and crank ( It did not matter with a carburetor when they designed your vehicle, but its not EFI friendly) and its just not plum worn out, you can install a time delay relay in-line to correct this I use relay part number 74985 from Delcity to overcome the switch design. This, in turn, will power the Sniper. Have a look at those.
