Computer Reset

Cadmaster · #1 09-15-2009, 06:48 AM

My buddy and I put the Superchips Mileage XS on my truck last night and the system errored out when it was installing. So we ried it again and it errored out againd. So we were like lets wait till tech support opens at Superchips and see what is going on. Now the real problem is that the truck no longer starts and the Programmer won't return my truck to the stock settings. I have removed the positive and negative battery terminals and let it sit over night and the truck still won't start. How can I get my computer to reset itself back to the factory setings?

You're going to HAVE to get Superchips' help on this one. The problem is the device corrupted some files in the PCM and disconnecting the battery will not return it to stock. Hopefully, Superchips WILL be able to help you, but if not, the only solution I know of is a dealer reflash of your PCM.

The corruption problem was possibly caused by a low battery charge. Make sure your battery is showing over 12.4 V at rest and that all your accessories (A/C blower, lights, radio, etc.) are off.

same thing happened with me and my edge. it lost voltage, and the programer shut down after it got the stock files off PCM. superchips should be able to fix it, your stock files are probably on the programmer, just call them and do what they tell you to do.

Well towed my truck to the dealer and they tried to reflash my PCM, but it would not take or send any signals. So the dealer said it has to be replaced. Does this sound right.

It IS possible. But did you talk to SuperChips about this problem? I KNOW I would have gone to them first.

I talked to super chips and they told me that more than likely my PCM was about to go and when the tuner went to reprogram it, it finished it off for me. I don't see how that is possilbe with only 47,000 miles on my truck.

This sounds pretty weak to me too. It CAN be possible they are right, but I doubt it. Sounds to me like a "brush-off". My opinion of SuperChips' customer support has just taken a nose dive. I've seen similar problems handled successfully by VMP, Troyer, PHP and Edge. In fact, if your PCM was in that bad shape, I'd expect other problems would have surfaced before this. Solid state units simply don't tend to fail like this, and if it's been working fine this long, it's all "burned in" and should have been good indefinitely. Oh yes, there CAN be exceptions, but they are very rare.

Since you have only 47,000 miles on your truck, is it still under warranty? If so, take it to a dealer, they may be able to reprogram it. And then, I'd get rid of the SuperChips unit and find something that comes with better support.

Edit: Sorry, I just went back through this entire thread and noticed you HAD taken your truck to the dealer about a month ago. What I posted above (in bold) doesn't really "compute", does it? *shrug* Hopefully, for your sake, the PCM is being replaced under warranty.

Even with a corrupted PCM there should be a way to force a tune into it. Back in the days when this was more common Superchips, Diablo and the others had a way, with support's help, to do this. Its not as common now, but it does happen. Basically, with the Predator they gave you a "up/down/left/right" sequence that was good for a couple of days which told the programmer to ignore the calibration id in the computer (since its corrupt) and to load a calibration for a specific application. Don't recall what the procedure for Superchips or SCT was, it's been a long time!

The battery needs to be in good shape to program the computer, and this is with either a tuner or the dealership. Turn off all accessories including the radio and ventilation fans, and keep the doors closed when programming so the interior lights are off. Try seeing what it will do then, and if you have a battery charger I recommend you fully charge the battery prior to attempting it. Superchips needs to back you up on this, saying the computer was about to go bad sounds like bs, the EEPROMs are good for hundreds of thousands of write cycles. Given the failure rate of programmers verses trucks, its far more likely that the battery or the programmer is the fault. Worst case scenario, buy a used PCM online as they run half price or better.
