I used to run 33.5 lol. Lowered it for new mods.

Anyway it's a LQ4 with TR220/112LSA/Stage II heads from WCCH/lt's/e-fans/under drive pully/cai/tb bypass/yank pt3200 stall.
Basically a heads and cam motor with the normal bolt ons to go with it.

Yeah can't get the tune file as of right now.
I am getting KR every time the converter locks at around 35mph. Figure i have it locking too soon and it's lugging the motor.
Then on the WOT first run i think it was road jitter making it get false knock.
Second WOT blast no kr at all....
Then i got down on it in another file and it got like 1.4 kr at the 2-3 shift then went away and so on......

gotcha. still a crap load of timing IMO. I dunno if that's why you were knockin, but man 6-8* of KR is a lot. you've got some issues at cruise too. I've never had a huge *** bump make me pull more then 1* KR. seeing that 8* of KR at 2500 rpm's means either A)timing issues or B)fueling table issues. I think it's just timing, but without having the .hpt file I can't really tell exactly. otherwise, looks like a nice truck. maybe looks a little rich too, but also I can't tell that unless I have a w/b input haha.

have you dyno'd the truck? what 1/4 you runnin?

another note on the shift issues. the commanded shift time could be fucked up. I've seen some guys that are trying to command a 0.000 sec shift time. The tranny has some serious issues with synchronization then. I'll tell you that my truck does kinda do a little what you're talkin about. Not for but a few milliseconds though. When it is going to shift the truck lunges forward during the shift. It makes it kinda look like the tranny isn't shifting right, but it is. kinda hard to explain so I might get a video of it in a little while.

Well the low speed cruise knock of 8 degrees happens every single time. Thats why i think i have the stall locking too early.
The one at WOT only got that high that one time so far on all my logs.
I have gotten like 2 degrees a couple times in the 2-3 shift area though.
Don't have a wideband right now. The truck was tuned in person a while back but i ahve made big changes since then.

Last i went to the track it went a 13.5@100mph.
This was with a 2600stall,stock heads,3.42 gears and running out of injector at 5200 rpms and basically untuned just a shift point tune basically.

Never went back but now the truck has a 3200 stall/3.73 gears/Stage II heads WCCH/42lb injectors and should be a much better tune than stock.....

At one point before the heads were put on i was running 36 degrees of timing and No KR at all lol.

I'm hoping for at least a 12.7-1/4 pass with the new setup. Those logs are also on the 20's in 81 degree air i think with about 300lbs of extra weight in the bed lol. Nothing like logging on the way to work haha.
