Hi everybody, im having a few problems with my stardard computer. First i will list what i have;
R32, RB20DET, silver top motor, manual transmission, 3" exhaust, 600*400*70mm intercooler, pod air filter, standard turbo. Regapped 0.8mm plugs
The motor is in a commodore. I brought the motor from the wreckers and i got a computer from a Nissan Laurel C33 with it. Everything works fine and the thing has been running like a dream for 3/4 of a year. I only just put the intercooler in and beause its sucking in much more air, due to it being denser, i have ran into a few problems. The car runs very inconsistly. Air/fuel ratios are the same, there is correct fuel pressure so the timing must be doing strange things. Sometimes it will feel very very quick, and other times it will lose about 20%. It wont be anywhere near pinging as its only sitting at 10psi.
Is the computer the same as for the gtst? Is there a difference between auto and manual computers? as my one is a auto computer and there is error 54 (auto signal to ecu) on the computers self diagnostics.
Thanks alot for any help.
