Reset Adaptations question

[TURBO200R4]

I think hanso tunes tend to be on the rich side and use a lot of fuel.

Ok before doing the reset adaption did you check the 7.0mm nut? Over time, and adjustment, they end up wound in too much and the stepper can move one way only. Easy to check by looking this. I back the 7.0mm nut off, do reset adaption, then set tps and stepper. Mostly works.

I can give that a try next time. TPS and ISCV are both perfectly within spec.

Correct they (the values) can be in spec but the mechanical adjustment on the arm set by the nut can be incorrect. When the system tries to adjust it cannot move in one direction. This can cause hunting and poor idle. This is why you back the 7mm nut off BEFORE doing the adaption reset. THEN do the TPS and ISCV. The 7mm nut will need adjustment just wont be at end of its adjustment. Have seen this numerous times is all.
