I'm looking into using Hondata but my car is OBD2. For those who run Hondata on their OBD2 cars, is this just a straight swap with OBD1 ecu and conversion harness? What about all the various sensors that are on the car, would any of those need to be changed out to work with the OBD1 ECU or would they all work perfectly? Any other areas or issues that I need to be concerned about when I run the Hondata setup?

 

Don't do it if you have to pass an obd2 diagnostic test. Or just run your stock obd2 ecu when you get tested.

 

That's all you need; Hondata, obd1 ecu, and harness.

 

Thx for your input

 

I ordered a socketed p28 ecu for my 97 gsr. I just need this, a conversion harness and the hondata box right?
P. S. Isn't the p28 from an obdII car, if so do I still need the obd conversion harness?

 

p28 is a obd1 ecu from a 92-95 civic ex/si

 

Ohh alright thanks,
