  • In this video I go over some Pros and Cons on the FiTech Ultimate LS EFI system. I also share tips that aren't in the instructions.
    The key to a good installation is proper wiring.
    I also upgrade the rear differential to an 8.8” Ford. I also installed Caltracs traction bars. Check out the video series here. • How to swap a Ford 8.8...

      I’m pretty sure the 944 has analog inputs to the dash. So you would have to put the Porsche coolant temp sensor into the passenger head, Porsche oil pressure sensor if it had one in the LS (the ls doesn’t need the oil pressure info to run, it’s just for the gauge), the tach signal comes from the fitech, also the fitech has the speedo output. I don’t know if the 944 has an electronic or cable speedometer though. BTW thanks for sharing my video. I subscribed.

      If you want a high strung race engine you’ll want a way more aggressive cam than the ls9. I would look up PatG on ls1tech.com and have him custom spec you a cam. You’ll probably want something with at least .600” lift and mid 230s duration. I’ve tuned tons of ls engines and the ones with custom speced cams are usually better than off the shelf cams. Definitely better than any factory cams.

    @Pete'sGarage Thanks for the video. By far the best on CZcams. Interesting swap choice! 100% agree that the factory ECU would have been best on this vehicle. I personally consider this system best for muscle swaps as most people running things such as electric fans have already wired relays and aftermarket fuse blocks. I installed this system on my 72 nova with a LM7 engine but have yet to complete fuel and exhaust systems. Question: regarding the alternator issues. My donor engine came from a 05 Tahoe running the 2 pin alternator. Fitech uses a 4 pin plug. I ordered a 4 to 2 pin adaptor and hoping it will work fine. What pinouts did you change? There is no possible way to connect the fitech harness to a 2 pin alternator withought some type of adapter.

My buddy is running FiTech Go600 w Fuel Commander on a 383 SBC in his '72 Chevelle and loves it. I think like you saw with the poor wiring a lot of the negative comments on FiTech are related to poor install techniques such as bad grounds etc. Thanks for sharing your experiences with FiTech!

    • @PetesGarageandperformance

      @PetesGarageandperformance  Před 5 lety

      I would use a factory ls1 pcm and integrate it into the factory harness connections at the underhood fuse block and the connectors near the pcm. You would need to compare wiring schematics between your truck and the ls1 pcm to see where to connect the wires to. Or you could just buy a harness and pcm from Current Performance and be done with it.

      Yes some of the aftermarket corvette filter/regulators show that exact symptom if it fails. Also if you have a big fuel pump it might be too much for the vette filter. If you have a high flow pump then you might have to go with an aftermarket regulator.

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 5 lety +1

      Yeah the FiTech is a great option if you don’t have an intake, fuel rails, injectors, throttle body. But if the swap is going into a newer GM vehicle that uses class2 for the gauges then a factory setup might be a better choice. Now your intake setup... maybe a Holley Dominator might have been the best option. Simply because those ITBs were beyond what GM had in mind! But it still works.

    • @finalcallracing
      @finalcallracing Před 5 lety +1

    Finishing an LS swap on a 2002 Lexus GS300 with this FiTech 750hp kit... how involved or difficult was to integrate the factory ECU to the FiTech to have your factory gauges and climate control work?

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 4 lety

      I’m not sure how the Lexus gets its tach and speedometer signals but those are the only two outputs that the fitech has. If the gauge cluster has a separate input for tach and speedo then you just hook the two fitech wires to those. Then you’d have to put the Lexus oil pressure sender and coolant temp sensor on the engine and thin out the factory harness so just those two things were on it. On this s10 the fuel level sensor also went through the PCM so that wiring was left in tact also. You can put the factory Lexus coolant temp sensor into the rear of the right head. There’s a plug you can remove. You may have to adapt the threads of the Lexus sensor, or you might get lucky and have it fit. You can also ditch the ls oil pressure sensor since it doesn’t actually do anything and put the Lexus sender in its place.
      As for climate control, leave the Lexus stuff there and just tie the “a/c on” wire of the fitech to the power wire that goes to the compressor clutch. So the fitech knows when the a/c is on and can turn the fans on and also alter the idle slightly. So you’ll also need to make the fans controlled by the fitech and not the Lexus ECM. Just utilize the factory fan relays and have the trigger wire hooked to the fitech fan outputs.

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 5 lety

      To keep the factory gauges you only need to program the factory pcm as I believe an 02 Tahoe. It uses the class2 data bus from the pcm for coolant temp, battery voltage, oil pressure, and fuel level. The speedometer and tach are separate outputs from the pcm. You’ll need to program the pcm to output either a 4cyl or 6cyl signal depending on what the truck originally came with.

      The factory ECM does have specific wires for speedo and tach. All of the other gauges are transmitted over the data line. So if you want any other gauges to work, you’ll have to use the factory PCM to just run gauges like I did in this video. I’m in the Kansas City, Missouri area. If you’re local I could help you out.

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 4 lety +1

      Is it the old or new body style Silverado? They made both styles in 99. If it’s the newer body style, the ls1 pcm should be the only one you’d need to use. If it’s the older style I think you can also only use the ls1 pcm but you’d have to run a redundant coolant temp sensor to run the gauge. But I don’t think you’d have to piggyback two pcms. The s10 needed it because the IPC worked on class2 data signals from the stock pcm and the customer had already used the FiTech. I hope this makes sense. Thanks for watching and subscribing!

      Yeah you might have to piggyback the two pcm’s. The factory 4.3 pcm can be programmed to work and would be the cleanest install. But it sounds like that might not be the best option due to tuners. That is definitely one of the beat parts of the Fitech, it self tunes the fuel tables. You do need to dial in the timing yourself though. But it is all done through the handheld so it’s really easy.

      I wouldn’t think that you would have to change the pins unless changing the connector over to the two pin style. I think part of the problem we ran into was that we were using an ict billet accessory drive with a truck alternator. You can see which wire has 12v on it when the engine is running. This should be the trigger wire to turn on the field. You’re calling it the stator but the stator is the output side of an alternator.

      Tubby T oh I didn’t realize you already had the fitech harness and ecu. You can either use the factory intake or the one from fitech. The problem you may run into with the factory intake is that the fuel injector connectors on the fitech are different. Also the fitech intake looks so much cleaner.

      Daniel Bedgood I think it goes to the brake switch. It is used so the ECU unlocks the torque converter when braking. I’m not sure if it is supposed to be powered when the pedal is pushed or grounded though.

    So how would you actually fully tune the engine? I’ve got a fully built bored out LS3, with supporting mods and with this efi setup it makes less than stock and I’m ready to throw this whole deal in the trash. I’ve spoken to some HP Tuners guys and they say I should be mid - low 500s and I’m sitting at 360 right now

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 4 lety +1

      To fully dial it in you would need a dyno to see what afr and timing will make the most power. It doesn’t matter what ecu is controlling the timing and fuel as long as it’s what the engine wants. The intake might make a little difference but probably not too much. What is your WOT AFR and Timing?

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 4 lety

      Open headers can really mess with the wideband readings. These systems rely heavily on that wideband oxygen sensor. Temporarily add a couple feet of pipe to the header to see if it makes a difference. Also are you sure your injectors aren’t clogged? Did they sit for a length of time?

      Anthony Williams I’m all about LS swaps because they make great power and are reliable.

It just won’t make the horsepower unless you get some good aftermarket aluminum heads compared to the LS engines.

    Hey man I’ve been having issues with my ultimate LS system and was hoping maybe you could help. For whatever reason when I crank with the fuel pump running and 58psi set on my regulator I’m getting a stumble and no-start. If I unplug the fuel pump, the engine fires up and idles with no issues. I’m not sure how that’s possible, but it will only run with no fuel pressure. As soon as I turn the fuel pump on the engine dies. I’m completely lost at this point and any tips would be much appreciated. Thanks in advance

    • @PetesGarageandperformance
      @PetesGarageandperformance  Před 5 lety

      I’m thinking your fuel pressure gauge isn’t accurate and you might be flooding the engine. I would verify the correct pressure with a different gauge. Which might be a little difficult because there isn’t a Schrader valve to check it. What do the wideband o2s read when you are supplying fuel?

    • @sliderrbharris
      @sliderrbharris Před 5 lety

      Pete's Garage for starters I’m running an ls3 intake and fuel rail/injectors. When I get it running with the fuel pump off it gets down in the 13.8-14.5ish range. As soon as I introduce pressure the afrs spike and it dies. I’m running an external gauge off the schrader valve on the rail and have the regulator dialed in at 58psi. I’ve tried turn it way down to around 10psi and it still seems to die as soon as it gets any pressure

      Ummm... 14.4 is the idle AFR. You want to idle as lean as the engine will allow. Anything richer at idle is going to be just wasting fuel. You want your Wide Open Throttle AFR to be 12-13. Some engines like 12.5, some like 13.0. That’s where you use a dyno to find out what the engine likes.
