Hi Turk, I'm about to embark on an S62 six speed swap into my newly aquired E30 M3. I did a swap with a s50b32 in my last car. I had a horri me experience having the ECU flashed that took two guys over six months to get it right. Can you refer a reliable source to flash the S62 ECU and provided a taylored wiring harness? I know there are a few guys out there but cannot remember who. Thanks for your help in advance!
