No way I've got great knowledge of this forum yet, but I do try my share of searches on a given topic. FWIW, I have done one on tuning the Vehicross and I haven't found threads where it looks like people have successfully accomplished it.
Until that happens (or unless I missed it), Chopper's statement may have some truth in the VX community. Beyond that, many people have done their own programming for an E85 conversion...especially in the FORD/GM circles. That's because E85 makes more power (and uses more fuel).
I'll be interested in this project for the success/failure of the ECU programming....hoping that OEM unit is successfully reprogrammed vs getting replaced.
