EBL TPS won't go above 88%
Noticed today that my TPS % won't go above 88% in the WUD. Checked that the throttle blades are opening fully, the TPS is at .5V closed and 4.2 WOT and swings smoothly through the range. Drivability is good.
Tried adjusting the TPS and it will go down from 88% but not higher so I set it back to .5V at closed throttle.
Is there something i'm missing? Any ideas greatly appreciated. Thanks!

Re: EBL TPS won't go above 88%
There is a gain term in the calibration:
TPS - ADC gain term for TPS%
It is between the "SA - " and "AE - " constants/scalars
Can adjust it with key-on, engine-off. Increase the value, flash (with reset ECM selected), then test (idle to pedal to the metal). Adjust and repeat as required until 100% is hit.
