Installed my 600 HP PA and works great. Cold starts are easy and no hesitation under acceleration, I love it.

[jesseford]

Great information.
Followed the instructions on my FITECH system and it runs fine.

Basics. Who would have thought? 😁 1200 PA working flawlessly and efficiently. Love the product

I believe my ECU just failed. I have had my car running for years with my FiTech unit. I was out for a drive, did a moderate acceleration through a yellow light. And immediately the engine and car changed to being barely able to run like it was starving for fuel. I had to feather it down the highway until my exit only going 50mph no shifting. Once I turned off the road it died out. We added fuel got it running barely, got it home, it killed the engine when put in park. We have cleaned the fuel filter, checked the resistive wire, and the keyed ignition white wire all have power. We had it running for a bit, turned off the ignition and noticed the fuel pump was still running. We turned off our fuel pump with an external kill switch. Checked later something had drained all the power from the battery until it was dead. Now the ECU will not respond to the hand held at all. We checked the power wires. The sensor and plug wires and all appear to have no damage. With this system, from what I remember it is supposed to control the electric fuel pump to vary power levels based on throttle. I am wondering if some kind of glitch may have occurred, and it cut fuel, and then it, kept power going to the fuel pump when it should have powered it off, and instead just shorted out the ECU internally.

To get the engine to crank, I need to turn the ignition key on and off twice.(spritz) especially when engine is cold. i increased the prime fuel mult and other items but still problem remains. after cranking all of things like IAC, rpm, tps and arf work good, my only problem is in cranking
My handheld is 2 dot, 30003
My engine is v6, 262 chevy stock.
Can you guid me please?
I am confused what happen

Can you make a video for spark map on the ultimate ls system? Got mine set at 27 across the board(besides idle) want to tweak my cruising spark to increase my mpg but not sure what direction to go with it

[diffmakersmith]

Can I set up system to run without a o2 sensor ( closed loop)?

Hello I am, fighting a tach signal issue on my new hot rod fresh 383 sbc I have the dual TBI setup w/MSD it primes fuel just fine and the motor with fire initially however no fuel after that due to no rpms showing up on the controller. Spark plugs are resister type and i have full voltage to the fitech system. Any thoughts on what it could be?

My workshop is trying to set up my FITEC3001 Go EFI14-600 HO kit but no matter what they try with the control unit the 7.2 litre, new Chrysler V8 continues to over

My fitech doesn't make that injector sqwert sound anymore and won't start ??

[DannoZ]

When is FiTech 2 going to be released? Has this system been update (other than software updates) since 2016?

[wheelmanvicful]
