add short term and long term idle trims also LTIT STIT get plenty of log with it completely stopped.

Something is wrong with the map sensor. It's reading about a 1/4 of what it should. The tune file is setup for a stock map sensor. Is that what you have?

It should read near 100kpa with the...

They work. but an old style that is not as clean as a lot of other options.

I'd be wary of aftermarket map sensors. There is a turbo company that sells one. I've had several come by the shop and all of them were bad.

Log fuel pressure sensor voltage to see if we can catch it not matching what is reported.

Also.. in the FPCM there are some useful pids like pump PWM %, short and long term pump trims. So if...

Change source from GMLAN to calibration in speedo tab

that doesn't look great to be honest. I'd continue to watch it... especially under a heavier load.

It sounds like you got a miss other than that.. have you done the simple things? Wires/...

Maybe let me rephrase. IF you swap to non dod hardware but do not disable the codes in the tune.. it will act like its missing at an idle.

Here is a copy of the post I was talking about on checking pushrod length. I very much think it's worth it.. Almost every cammed car we pull apart all have 7.400's and quite a few have chewed...

I recommend checking pushrod length on every build. It's pretty easy to do and we think saves camshaft life + reduces that sewing machine noise. The same setup on two cars will often come out...

I recommend at least 15 minutes of data of DRIVING to work with. Snapshots don't work.

Also these have a injector tip temperature offset table that maxes out after a reflash. It takes about...

There are several remote tuners on this site that could help tune this for you remotely. I do it often for people all over the world. Someone should make a list of tuners on here that do that type...

If you disable DOD and do not disable the codes it will act like its missing at an idle.

only the last table in that list is used..

There is a pid you can logged "MAF status" or something alone those lines. Make sure it says MAF failed. Make changes to the last table in that list...

Some trucks come with quite a bit of fuel supply.. some don't.

Since this is a swap.> Have you checked fuel pressure while it feels like it's falling on it's face?

awesome!

Also the map sensors settings you are using do not match anything I have references too.. Which PN sensor are you using.

This is the second time this week I've caught this for someone..

In GEN 3's there is two min PW settings that MUST BE changed when doing large injectors. Some people preach to modify this.....

It's going full throttle now.


Look into the GMPP catalog for the crate engine + 6l80 setups. The "stand alone" controller isn't one like you would think. It's not a separate box or anything.....

I'm not certain but this looks like the newish GMPP LS3 kit with a 6l80.. It comes with stand alone software for the T43 but it will read and somewhat work with HPtuners. In those setup/files the...

I doubt you could brick it..

Let it sit unplugged overnight.

On that model car. You do not need to make any changes. It might make some more boost and need fueling/spark changes.. but nothing like the old days with big throttle bodies and ETC scalars.

This looks like BTM to me.

You should have been instructed to hook up a brake wire when doing the GMPP kit. Double check instructions wiring.. in the meantime this might give you a work...

no they don't.. e40 tbss use 24x 1x cam.. E67 use 58x 4x
