I have the Superchips chip for code JFA8, and I was using it on my JFA7. It was goin good for about 6 months and then my car wouldn't start so I reset the ECU by disconnecting the battery. I went to the dealership they didn't find anything but they reflashed my PCM with a different code, which one I'm not sure but I think it starts with a Y now. It has been running fine for about a week (with the chip in), now it didn't start again when I was filling you with gas but somehow it started after a couple of minutes. Then the "!" light went on and my car bogged then it went off and repeated like 5 times. Then I got on the highway accelerated a little the car jolted and the CEL when on so I pulled over. Drove to the dealership with the CEL on and they said that the car had overheated. But the ECU also only recorded a temp of 192 degrees which is normal. Could the chip be doin this, or is this unrelated? Also can I get the chip re done to work with my new ecu flash? Thanx.
