went to a local dyno day and did some pulls. there seems to have been a problem with the ignition pickup, so some of the data is missing from a few of the runs. they ended up giving me about 7 runs total for 55bucks (not bad)... but i only ended up with a few useful ones. next time im bringing a video camera with me to record my gauges and wideband while i dyno so that i can remember exactly what boost level i was at for each run.
this would have been my best run, but as you can see the ignition pickup dropped out during the run. grrr.  this one is probably the best and cleanest run, with no data missing.

Any tuning there? Why is it so lean? no tuning. bone stock. i have no idea why its running out of fuel. i read on mr2oc before that on some cars, the afm never goes to 100% open, so maybe thats the problem there. i think that run was at about 15psi while the 2nd one was at 13psi, yet the hp didnt change because in the 15psi run, i didnt have enough fuel.

Any tuning there? Why is it so lean? I thought less than 14.7 is considered rich? the second run looks rich to me, do i have this all wrong? please correct me if im reading it wrong.  14.7 is stoich. on a WOT run, you want the a/f ratio to be in the 11-12s. 13-14 would be considered too lean while under full boost. the 1st run posted is a little too lean, while the 2nd pic is perfect at 10-11afr This post has been edited by lagos: Nov 5, 2006 - 4:45 PM -------------------- 15PSI - 30MPG - Megasquirt Tuned
