Having a few problems with burning chips
This is a new problem on a old setup. Late Friday night I stayed up late burning chips so I would be ready for the dyno. This is a b18a OBD1 motor, with a chipped PR4, WITH A BURN 1, I was going to start tunning my NA setup because I am waiting on some turbo parts. This is going to be my plan B setup.
First chip, I took a stock map and did the fuel tables and made some other small changes.
Sencond chip, made the timming tables all say 16 for dissy setting made easy, all the same fuel trims.
Got the car fired up on the 2nd chip. It ran pig rich and the CEL was one the whole time and no codes would flash. So we plugged in the 1st chip and everything was great. It ran pretty damn good. I drove it around the shop a couple times to make sure everything was ok. No codes.
PROBLEM
I found a flat spot in it at a lower RPM that I tried to fix before we put it on the dyno. Now, I can't read, erase, or program any thing. It did one chip prefect then it's like a switch got flip on and I can't do ----. Does anyone around here have any idea what the hell this could be
?

Re: Having a few problems with burning chips
My offsets are
Chipping address
008000
00FFFF
Buffer is set at this
000000
007FFF
Which I think is right?

PS all chips that I have tried do the same thing, CEL on all the time and runs very rich. Then put back in my first one and runs like a champ.

Re: Having a few problems with burning chips
3 days of no dynoing really is starting to **** me off. I don't have a ------- clue. I spent about 5 hours looking around here and PGMFI.org. I got one chip that I burnt the good program on to not have the CEL for about 2 minutes, still pig rich and then the light comes on. Check for codes and nothing. Put back in the one chip and everything is happy again.
I think maybe I should go buy some thicker rope.

Re: Having a few problems with burning chips
You HAVE To erase the chips first. New chips for some reason always burn bad if you dont erase them. So your offsets are fine. Load file to buffer, erase chip, program chip. done. make sure you have the chip in right. Arm on top, chip goes in the bottom slot, with the notch closest to the arm ,with a few slots empty inbetween the arm and the chip.

Re: Having a few problems with burning chips
I know it should be that easy. That is how I did a few of them now and they just don't work. I am installing all this stuff on a different computer as we speak. I am just trying a bunch of random ----.
