Nice find on the pdf. I did read thru the pdf and one major sticking point was the statement "all vehicles capable of PCM reprogramming"

I've seen it discussed a few times and it was shown that the ecu has read only chips. If they are read only chips, fixed set of instructions and programming... then you can't reprogram them. No matter what a pdf says. Even if it was possible I think those MUT-III are pretty expensive.

Gray get's a bit touchy when someone questions him but I'd pay attention. He knows his st*t on these cars. This has been looked at before. Either way I agree with cbehnken, I want to have control either with a piggy back or AEM. Stuff that I can program and change myself. I know a guy at work that owns a VW turbo beetle. He sent his ecu in for programming to go with the kit they sold. He wants to upgrade a few things but he's not sure if he can now since he has zero flexibility with his tune.
