I just cut the "J1" jumper to put the ECU back to stock. Got me through e-check.

Will writing the 304stock.bin to a chip make my p28 work just like a stock ECU? Or do I need to "dechip" my ECU if I want it to work like a stock one? And is that the right .bin for a 92-95 civic?

Have you tried lowering your cranking fuel adjustment? 0.413 would be a good starting point.

What year and model?

^^^ It also has a miss at idle that can't be narrowed down to one cylinder.

I have an intermittent missfire with my d16z6 with Greddy turbo. Sometimes it's minor, sometimes it's pretty bad. Here's a .rec graph of a bad one. Any ideas?

Is it possible you have the MAP and IAT connectors switched?

is the math right though, or am I missing something?

I have my fuel tables set so that it runs right at 12.2:1 under boost. If I wanted it to run about 12.5:1, could I adjust that portion of the fuel table by 2.5% and be close. (12.2 + 2.5% = 12.5) Or is there a flaw in my math?
