I put in a B20b engine in it and the tranny or ecu doesn't seem to be compatiable. Is the 94 auto LS tranny same as the 96 auto LS tranny. I know 1 is OBD1 tranny and 1 is OBD2 tranny which i assume is the same. Can any1 tell me if the gear ratio is the same or different? Rite now the car rev's and change gears at 6000rpm. I think there is something wrong between the ECU and the tranny. I have a P75 obd1 ecu but the tranny is a 96 obd2 tranny. I think there is something wrong with the gear ratio relating to the pressure. Can someone tell me what is wrong with it? I just want to change gears like a normal car and not 6000rpm all the time even at light throttle. Someone pls help. I know is not the tranny itself because this is the 3rd tranny i've put in.

 

No it is not the same hence the OBD1 vs OBD 2

USDM DC/DB integras from 94-95 = OBD1
USDM DC/DB integras from 96-01 = OBD2a or OBD2b

The problem lies with the mix match from the Transmission as the ECU is programmed to read OBD1. Go Search Honda-tech.com for relavent info.

Is there any CEL codes?
