Ebay GT45 + 5.9 Magnum + E85 blow thru
Been tuning and testing the FiTech unit last two days. I'm impressed so far. Damn near plug 'n play. Their documentation is a little wanting, but the email support is great. Went out tonight and ran it threw the gears at WOT. Turbo seems to spool up pretty fast and my WG spring is working. I'm hitting about 5psi, which is my safe starting point. My target AFRs seem to be right on the money with the Fitech. Engine cut out at the top of 1st, so I let off a little (quickly said "humm?" to myself) and then proceeded to lean back into it, going through 2nd and 3rd. Thought I logged that run, but apparently I didn't. Looked at the tach recall and saw that I hit 6200RPMs. Bingo! That's where I set the fuel cut control on the FiTech. That explains the cut out. Mystery solved and fuel cut control works.
Torque/boost is awesome on this GT45. Can't wait to get it to the track though I'm sure I'll have a lot of bugs to work through and the overall behavior of the car will have changed so I'll need to get to know it again.
