Recommended by Keydiver aka "Jeff O." for ECU socketing/repair.

Absolutely amazing work. I sent in my ECU on a Monday, got it back Wednesday. New Caps, ZIF socket, other parts replaced. His work is noticeable only if you look Very closely, otherwise it looks factory. The "board" also got a bath and a protective dialectic covering.

I'm Very happy with Steve's work.

Steve Piette just refurbed my GVR4 ECU and did an amazing job. The ECU is beautiful, looks new and even came with that new ECU smell /ubbthreads/images/graemlins/grin.gif. He was very responsive, helpful, professional and provided a service report. It was time for another set of caps and there was some acid damage left over that needed repair. Highly recommended!

Definately a great guy. My GVR4 ECU was throwing 5 codes. He fixed all of them and my ECU is as good as new. I did the whole transaction at his house and not through the mail. He was very helpful with driving directions and troubleshooting my car problems.

+1 for Steve.

I have to say this was absolutely one of the best transactions that I have ever had with a dsm'er. I sent in my ecu on a Saturday, he got it on Tuesday, and I had it back by Friday. He turned my dead ECU into a fire breathing monster. I had him repair the board, replace the caps and install my keydiver chip; and he did an absolutely amazing job. I think I might send him the "back-up" ECU that I bought from someone that was dead also. Thanks again Steve!!
