Title: Throttle Position (min & max) Question
Post by: onenastyviper on June 12, 2021, 19:38
Hi,

Just had a race day and wanted to check a few ECU parameters STFT, LTFT just for reference.

I noticed by TP (Throttle Position) is 11.4% off throttle and only 78% full throttle (throttle body on stops).

Does the ECU account for this and learn/know that 78% is WOT?

I think those values are normal.
I  reckon the ECU only cares about the rate of change for acceleration enrichment, doesn't care what the the actual throttle position is.

I just hooked mine up to the scanner and mine is 11% and 78% also.
