got my flex fuel setup installed... out doing some WOT runs getting it all dialed in. it's all going very well until ~20psi, when i run into two problems:

- the grimmspeed ebcs is maxing duty cycle trying to hold boost above 6k or so with the 7psi spring in my turbosmart gate. annoying, but i can fix that.

- i can't get the damn car to hook up through a whole 3rd gear run from 2.5k to redline. everytime it spools it just spins. fun, but kinda makes tuning a bit difficult. even 4th gear kinda skitches around through the peak torque area spinning quite a bit. time for something better than cheap kumhos, i guess.

anyway, so while i was playing with the wg tables trying to see if i could eek out a bit more boost out up top, i was doing a wot run and my cluster lit up with the abs light and traction control lights. it had been spinning all the way through 3rd again, but this hadn't happened before.

i pulled over and checked for codes and found code 'C1234' in the ABS module. ecutek docs don't even reference this, and a google search is pretty inconclusive. has anyone experienced this, or does anyone know what this code references on our cars? i cleared it and it didn't come back, but i haven't done another run since....
