I have a 91 GS, earlier when I purchased the car I fried the O2 sensor and could not get a code for my CEL when I jumped the harness. I was going to have a Spoon PR4 chip installed today on my ECU... This chip is for a 90-91 integra RS GS LS 0BD0. My ECU looks nothing like the other OBD0 ECUs I have seen, it has no code light like others have talked about either. The control chip on my ECU has 32 pins, when Supposedly the OBD0 ECUs should only have 28 like the Spoon I ordered. I will try to post up some pics of mine later... Can anyone tell me what the deal is? I'm freaking out. Thanks, Kyle
