what if i drove to dealership with my labtop. flashed it to stock there. have them re-program it. then i can flash it back to my tune. i think that may work.

i mean how bad could the car drive using the default with a supercharger anyways? it would still be drivable at least right?

I doubt it. Especially if you're running larger injectors. Your idea of flashing stock tune at dealership sounds pretty good imo

right until the car starts throwing misfire codes while they pull it into the service bay, and the tech attempts to go ahead and fix those codes...

just be honest with them about it, let them know what you're doing, and how the car will not be driveable while they program the key.

no, i dont have larger injectors. i have an automatic. supercharger, flex fuel kit.
custom exhaust system. thats it. i think it may even be drivable on lower RPMs. im not really sure. the tune came from Moto East. But that was three years ago. Should i email and find out? Are they in business still, does anyone know?

i know right, i need to make sure i communicate it clearly to them to not move the vehicle once the tune is back to default.

Unless you can get it at zero boost... It'll run lean. Probably. Check with your tuner maybe.

Driving it with a stock tune is what I'd be worried about more. Stock tune should be fine just to start up and let idle, just to get an OBDII reading.

I talked to Mike over at Moto-East (now Xero-Limit) because he was the one who did my tuning. He couldn't give me any explanation why the dealership can't communicate with the ECU. Nobody can.

But he said what I need to do is just replace my 3 bar MAP sensor with my stock sensor, then re-flash the tune to stock, and do this at the dealership so they can gingerly drive it to the service bay, do the work. then i can put back in my 3 bar map sensor, then re-flash it back to my tune.

Crazy right? Absolutely nuts I need to do all that just for them to fix my check engine light and also re-program my key-fob.

Back to really simple. Had a friend that my "good" reader would not work, but the cheep one would. It seems that the connecter in the car is not great. I used an extender cord with the good reader and all worked well.


Just a thought.

That does sound like quite a mess. I'd try an indie locksmith, i had one copy my current key to an aftermarket key (obviously doesnt help your AC issues)
