hi guys,my question is i have a b18c gsr motor in my civic it had a automatic tranny but was swapped for a manual tranny, i still have the stock ecu in the car which is odb1,would i be able to jack in a odb2 ecu or is there a conversion harness available for me to do so,thanks in advance guys.

 

It'd be cheaper to chip the stock obd1 ecu to run the gsr maps (and better for tuning and all that) than to buy a conversion harness and obd2 ecu, but yeah, you need the conversion harness.

 

since it was originally obd1, you have to get an OBD1 ecu because the plugs on the ecu are different. get an obd1 ecu because its alot better. i like the p28 ecus that are chipped.
