Well my hunting paid off. I was looking for the first version of the EFU. The one with the analog and digital inputs. This version is no longer sold. [:@]
Came across the newer version on eBay. It was $225 and did not meet the reserve. Just so happened that the guy had just sold his TT on another forum. He had an email and number posted. Picked it up for $200 shipped got a great deal .
I was running a Turboxs DTEC-FC in a Scion xB that I supercharged. ( Went from 95hp to 141hp at the wheel) But I had no place to mount the Gameboy in theTT. The pic below is my xB with Cassia Riley from Penthouse. The Penthouse crew was staying across from us at the car show.[8D]
