| The ST4 uses the non linear TPS. You can't reset it in software. That function is for the linear TPS used on 749/999 etc. It's a function that shows up in VDST because of the 5.9 ECU being used.
The extra click on the mixture have probably given you the improved running. The TPS reset could/will have thrown it out.
Only way to set it is with closed butterflys and the 150mV setting. |
