Need some tuning help LQ4 w/ ms3
ok I got this LQ4 into my s13 its all wired up, everythings good so far, but it wont run for longer then 10 seconds. I've changed the injector table using that excel spread sheet but thats all i've done so far. I wanna put it in maf open loop because i think with the cam it wont run right but i cant figure out how to do that. Any help would be greatly appreciated!
Oh yeah here's the setup
LQ4
ls6 intake
44.5 lb/hr injectors
ms3 cam kit from texas speed
tick performance stage 2 t56
I'm using a painless wiring harness for an auto trans and just left it unplugged.
Going to need to post up your tune file
1998 Z-28: lid, full exhaust, 3600 stall, drag radials = 12.08@111mph
With that cam you're going to need to setup your tb again. This will involve adjusting the set screw and resetting your TPS. From there, its going to be VE adjustments and timing you'll be working on.
As 346ci said, post your tune and perhaps a scan once you get it to idle.

If you are looking for tuning help... you will need to post a tune, and a log with a config would greatly help us help you in what direction to point you in. I am assuming that it runs for longer than 10 seconds if you are posting dyno numbers...
