Hello everyone. I have just installed a 98 ECU in a 97 GSX. The car is now throwing a P0446 code and dying at idle after 20 minutes or so of running. All the my research is coming up with very limited info. The only applicable post I have found is posted below.

Now on to the details; Both cars are completely stock. It's a simple ecu swap in preparation for upgrades and tuning etc. I have no experience with a 97, only 98-99. I realize there is a difference in the evap sensors. Is there a straight forward fix for this? IE - Can I simply replace the 97 purge solenoid and pigtail with the one from the 98 and fix the issue or does it actually need a differential pressure switch added to pin 61 of the ECU? I can find no info beyond this point on the issue... I am continuing research but it is very slow and frustrating at this point. Any help would be massively appreciated...
