My car ls a bmw e36 with a m50b25, 403 dme.
This week I put a set of individual throttle bodies from a 1000 gsxr.
I run with no maf (unplugged).
I have some problems of lean AFR in fast throttle : AFR reaches at 16/17, and then go down to 11 (I run E85, my wide band controller is a Zeitronix ZT-3, so AFR values I give are the displayed ones).
I think I think that the problem come from my TPS (I use the GSXR one), who gives incorrect values at low throttle and at idle: 1.2v instead of 0.5v). Does someone knows the correct range for these values, at Idle and WOT?
Because of that, I also have no Idle bevause I think that the ecu dont see thé Idle state because of thé wrong values from TPS.
I think I need To modify throttle définition table, I think I have find It in 6E4D, (31x1). I have converted thé table values To airflow %, x axis in throttle % (I think in reality it is TPS voltage but dont know thé conversion factor). See on this picture:

Can someone tell me if thats thé good one and give le some advice about my setup?
