i want to do a obd2 to obd1 conv., i have a 2000 gsr, my friend is selling his obd 1 ecu, and it is a p28 ecu, will it make a difference what ecu im running? im new to all this, i see that other people are running p72 ecu, whats the difference? will my car throw a cel after the obd1/obd2 conv? will my car run better or stay the same?need some info. thanks

 

You'll need to get a obd2 to obd1 jumper harness. For the p28 ecu to work, you'll need to get it chip with a p72 program for it to run without throwing a cell.

 

Your car is not going to run better with a stock p72 ecu.
Look into an aftermarket intake manifold such as skunk2/aebs along with a chipped obd1 ecu.

 

well i wanted to go turbo in the furture, what do i do then? still get the ecu and still leave it stock or get it chipped anyways with the p72 program, but if i go all motor can i just send the p28 ecu to hondata and have them program it.

Get an ecu chipped for your current setup, then you decide to go turbo then your ecu will already be chipped ready for honda/crome/uberdata etc.

 

If you are going turbo and you wish to run Hondata, get a 94-95 GSR p72 ecu. You will be converting to OBDII and you will retain the ability for the ecu to pull timing via the knock sensor. A p28 does not have this function.

so i have to get a p72 ecu(obd1), why will i be converting to obd2?even if im converting to obd1 with my harness?
