With all of those misfires you are also probably using the "bad fuel spark" table which does have 15* as peak at wot... aka LIMP mode... hence my next statement.

All I'm going to say is knock it off... Your going to break it doing that right now... Get rid of the misfire issue and start to do OUT of boost tuning, then don't go into boost till you can log the wideband to ensure there is enough fuel and get out if you pick up any KR under heavy load. Just some very necessary boost tuning tips...

so a new ICM at my price is $187. and i didn't think the knock sensor was actually reading anything that i noticed.

i mean its possible there's still some bad gas in there as i think travis has only filled it up once or twice since he got it.

looking at the LC-1 wideband under boost, it appears i have a good A/F... could be wrong though

a/f may be good but the misfires are not helping it and can start to cause issues... I would stay out of boost till you know that's fixed.

I can send the ICM tomorrow if you still want it... you never said to send it for sure and I was gone all weekend racing in NH.

I'd start with testing it though to see if it shows anything... and really you can use any ICM from a 3.1MPFI all the way up to an 05 3400 if you would rather just try a JY pull than me sending one.
