i have a 2000 acura integra LS 5spd and swapped out my obd2b ECU for a OBD1 p75 w/conversion harness. i made the swap because im going to have a straight pipe and don't want that stupid engine light into limp mode. i swapped out the ECU and my stock tach doesn't work BUT my autometer one does! i put back my OBD2b ECU and both the stock and autometer tachs work. HOW CAN I HAVE MY STOCK TACH WORK WITH MY OBD1 ECU? do i need to mess with the ignitors or something? PLEASE HELP...!

 

to the top!

 

want to know to going to be doing this with my Turbo setup soon!

 

i converted my 98 teg to odb1 and everything works fine. i think something may be wrong with your odb1 ecu try a different ecu and see what happens.

well my car is a 2000 which is obd2B and yours is a 1998 which is a OBD2A. and i got the ECU straight outta my buddys car where everything functioned perfectly

 

I bet there is a problem with the adapter.
