ECMlink Help With Tuning (DSM Link)

You have a TPS DTC code - check that out first.

My guess is your knock is from high timing. If you look where it starts (3.2 knock at 3475 RPM), in the DA table it's hitting 19 + the 1 from the sliders. This is why I always recommend using one or the other. You can either address this in the DA table or the sliders, but just remember when you make a change in one, it will work with the other to give you your final value. If you only work in one space, you've made it much easier on us, and you, to trouble shoot and fix issues.

Also, 2nd gear pulls don't really tell us much. Next time go for a 3rd gear, WOT (foot to floor), and about 3k to redline if possible.

oops must have forgot to set the sliders to 0 i meant to do that already haha. I have been adjusting using the da tables only. Would the knock subside once the timing goes down or does it continue because it was spurred by that one cell with the higher timing. Also tomorrow ill post a full 3rd gear pull.

I'd start by zeroing out the sliders, then see what happens. If it still knocks, track the log while viewing the DA timing table and where the knock starts (and a bit after) pull the timing down.

zero'd out the sliders and went for another little drive to the store like a mile away. I had actually lowered the timing in the 3 timing rows from the bottom pretty low to help as well. Still pulling timing and ive been told thats because of the 2.4l. I guess they require alot less timing. It definitely pulled harder though and i will continue to tear into it tomorrow doing some more extensive pulls. I think i have the SD table pretty set though because my actual afr is very close to what my afratioest is.

alright so here are 2 logs of 3rd gear pulls. Seems the boost was a little high so i turned it down after these logs. I will continue to post logs as i adjust timing and boost.

i dropped boost down to about 19-20 and took some timing away and it is definitely pulling way harder now. I will post another log tonight after i drive back from work
