Hey guys, I have an 00 si and just got a 95 gsr ecu and jumper harness. I plugged it all in and my tach doesnt work at all, any ideas? Also what real benefits am I gaining from using that ecu, it doesnt seem to much diffrent when driving.
thanks

 

for sure p72 ecu wont make your car run or drive right because air/fuel ratio, map and displacements are off. there is no benefit of using stock obd1 p72 ecu on your obd2 si civic

 

hello i need a conversion from obd2 to obd0..im doing a h22 swap in a crx..if do let me know asap...

is it possible to use 2 different connections..like obd2 n obd1 connect to obd1 to obd0..if possible let me know asap...thanks
