5.7 NGC4 Electric Throttle Body-> Adaption, When disabled Fuel trims goes crazy low

[[email protected]]

Why disable Adaption for throtle body makes LTFT and STFT for both banks goes to up -30%. I've tried to decrease VE tables but it doesn't help. When I set Adaption to Enable with decreased VE tables Trims goes up and I've get lean MIL. What is that option for?

the adaption has multiple functions, I dont think that anyone knows the complete functions.

disable it helps by rpm hanging.

maybe you got other problems like leaks.

I havn't any leaks. If there will be leak, trims should go to + instead of -. Everything works fine but I tried to disable throttle adaption and it makes trims go crazy. Even if I correct VE tables still it goes to -30%. When I reenable adaption and restore VE tables it works fine. It seems that PCM couldn't work without adaption enabled. I wonder if someone disabled it without any problems
