Steve,
I really have no idea how a JET chip would fail. Probably many different
failure scenarios. I would hope that if it failed, the engine just
wouldn't run, that way you
could just unplug and remove the chip, replug and the engine would start
and you would know the chip was the problem. I have had one situation
where the chip
wasn't seated, the truck wouldn't start. If you really suspect the chip,
try disconnecting the battery, unplug and re-seat the chip, then
reconnect the battery. Allow
the stock ECM to re-learn. There are approx. 14 adaptive cells in the
stock ECM for ignition and fuel offsets. It takes approx. 50 driving
miles and two drive cycles for these to be modified, and they are
continually being changed. I suspect that weather has more to do with
the power variations than the chip itself (providing the chip is still
working).
