GIAC Chip Problem?

[nrowensby]

Okay... I have two ECU's one chipped... one stock. When running the GIAC chip, my car will occasionally just shut off. Sometimes it while sitting at a stop light, sometimes when I am cruising down the road at 40, other times while I am doing 80 down the interstate... I see no pattern, it's just like a random shut off... no CEL's.

Any ideas? I have never had a problem with the stock ECU...

Maybe your chip is disconnecting from the encryption board occasionally....

Had the same problem with APR chip due to bad/loose soldering. Was getting a CEL though....intermittent power to ECU and could hear clicking sound under the dash. After shipping the ECU to APR for re soldering all was well.

How much did that run?

As previously noted, it is likely a loose solder joint causing an intermittent signal from the chip socket to the ECU. I have a solution for you. Check your PMs.
