Exclamation ProCal / Check Engine Light HELP

Hey guys...

I emailed AEV a few days ago, but I haven't heard anything back yet, so I figured I post up here to see if I could get any help. Below is pretty much copy and paste of what I sent AEV...

I've successfully used (and had) my ProCal for about 6 months now. I've used it for configuring my tire size, gear ratio, and even turning on day running lights.

However, recently I took my Jeep in for dealer service. I had always heard that restoring your Jeep to stock was a good idea, so I did. I selected the "restore" option, and programmed the vehicle like normal. However, unlike normal, the Jeep honked 3 times. When I started the Jeep it then had it's check engine light on.

Pressed for time I went ahead and dropped it off as-is for dealer service. The dealer said the check engine light was because of my larger tires and gear... odd, I am not sure what to make of what they thought... either way...

After I got my Jeep back, it still had the check engine light on. The speedometer worked, but it was off. It was showing that I was driving much slower than I really was.

I have tried EVERYTHING I can think of to get the check engine light to go away, but it just will not leave. I've tried using the ProCal's clear DTC codes feature, but when I try to the Jeep does nothing. It doesn't even honk, and it sure as heck doesn't clear the codes. I've been successfully in re-programming my correct tire size and gear ratio, and my speedometer is now correct. But, I would really love some assistance in understanding why the restore function did this, and how to correct this.

That's the strange thing...

I did the key cycle check.... And it just shows "-----" then done.... From what I've read that means no codes

Nope. I even called them this morning, went right to voice mail. I left them my name, number, and a brief description of my problem... They haven't returned my call or my email at this point.

I am a little puzzled at AEV's lack of customer service.

I did those steps the other day, with no luck.

When you clear DTC codes is it supposed to honk like the other functions do when they "take"?

The book says it may not honk depending on the vehicle code in the system.
