After installation of Nick Williams 102mm throttle body and a tune that seems to be working pretty well, I'm noticing a "dead zone" in the throttle pedal from roughly 15% to 35% pedal position. After the pedal is passed that threshold the car suddenly becomes much more responsive to throttle. Tuner says it doesn't look like a "tuning" issue (afr or timing). It's making the car difficult to drive and unsafe especially in corners. After examining the log , I can see a big difference in the ramp rate of the pedal% vs the TPS%. TPS% and Desired Throttle% are almost identical as they should be , but the pedal just seems to be on different curve. I'm tempted but scared to mess with the ETC tables due to the warnings. Are there other values that will help get my pedal more in sync with the TPS?
Love this forum and all the info. Any help would be much appreciated , thanks guys!
