I have a 94 5.0 with a JMS custom chip in it. For the first three weeks after it was installed, the car ran great (better than ever) But just after that, it started to ping again at part throttle. I could figure it out and started thinking I was experiencing another problem. As an experiment, I reset the car's computer by disconnecting the battery for 30 minutes. After that, the part throttle pinging was gone again and the car, again runs great with no pinging what so ever.

Is it possible for the computer to learn around the chip after a short period of time???

Please, any help would be greatly appreciated.
