I have about 1500 miles on it since I got the engine back in and MS running. No problems at all. I'm still tweaking the tables. I need to work on the warm up and afterstart enrichment. It idles at 900, and I got 26.5 MPG on the last tank, so I guess I'm not doing too bad.

Once I'm sure everything is right, I am going to strap on a T3 60 trim and start the tuning process over again.

Dialed in a little more. Having trouble with a stable idle. hunting from 650 to 1150.

TSEL was jumpered to VROUT and not VROUTINV. Fixed that.
Cam was 1 tooth off on the timing belt.

Lots more torque now!

No more miss. Idle is 900+/- 40 without closed loop iac.

Can't seem to get the 2 wire bosch iac to work right with closed loop. My pwm iac output seems to be inverted.

Added T3 60 trim @ 6psi for now.

Attached is the rough .msq

Still need to clean up the fuel table.

15 PSI now. Knock sense installed and working. No traction in 1st and 2nd. Some wheel spin in 3rd. 205/50/15 Yokohama AVS ES100s 020 gears w/ open diff ......
Spark map is tuned for 93 octane.
Going to install boost control option soon to reduce boost in 1st and 2nd.
15.1-15.2 at cruise 30-31 mpg

Switched to hires code a while ago. Helped a lot with idling on 50 lb injectors. Been using Megalogviewer VE analyzer to clean up the VE table. AFRs are a lot smoother now. It is very drivable. Still messing with the closed loop idle stuff.
