Thread: Terminator X Max lean AFR at WOT.

  1. #1

    Default Terminator X Max lean AFR at WOT.

    632 cid. No matter how much fuel I give the engine, it reads lean. But it seems rich, it's definitely popping through the throttle body only at WOT. Everywhere else car seems fine. Maybe someone can look my Global File over see if I missed anything?

    I'd advise getting some help from someone that knows a little more. Your Duty Cycle, Closed Loop & Learn are maxed out. At some points, you're adding over 1300 lb/hr of fuel. That's enough fuel for over 2000 HP.

    632", 9.0:1 C/R, 265°/275°, 113° LSA, advanced 4°. I want to spray nitrous at some point.

    I think I may have found the problem, low impedance injectors on a high impedance system. I used my old injectors from a large turbo engine on the Terminator X Max. Could this be my issue?

    Yes, the Terminator X & X Max only has high impedance fuel injector drivers.

    @albertg: That would do it! Hopefully you didn't damage the injector drivers.

    Ordered my new injectors last night. I'll let you all know if this is my problem.

    New injectors fixed it, and I did start the tune all over. Thanks for the help from everyone!
