YOU THINK ITS WORTH GETTING AN OBD1-OBD2A CONVERION HARNESS? HAVE A GSR ON AN EG AND I WANNA RUN THE P73 ECU LET ME KNOW

 

That's an expensive way to run an ECU that isn't mapped for your GSR cams and doesn't have an output to control the secondary butterflies (IAB) on your GSR intake manifold. You're much better off putting your money into getting tuned with Hondata, Uberdata, etc. Then you'll get something that is actually tuned for what you have, not an entirely different engine. So no, I don't think it's worth getting a conversion harness and an OBD2 ECU. If you're still not convinced though, I make conversion harnesses and will gladly sell you one. I also chip ECUs if you want to go the Hondata/Uberdata route.

 

is it safe the run the p73 ecu on a gsr with a skunk2 intake manifold? since the butterflies are no longer there?

 

Yes, but you'll still have maps for a slightly different engine with different head ports, compression, and cams. But yeah, it won't hurt. Getting it tuned is still the answer though.
