Log file example. no rpm, no maf, fuel system status..... you get the idea. what am I doing wrong here? thanks.

Ive been using HPtuners 3 years, do mostly stock engine LS swaps. When I started using these programs, VCM Scanner worked great, all the basic data showed up. Now, over time, I keep loosing function...

I dont. its actually very random and very hard to duplicate. Does it maybe 1 out of 50 tries.

It took a while just to figure out its the 4.8 ecm's causing the issue. Has happened on about 10...

No and No. Functional MAF

That brings me to my next question. In OEM application the 4.8 and 5.3 in the silverado use the same throttle body and throttle pedal. Wouldnt you think the ETC tables would be the same in the ECM?

LS swap vehicle, using 2013 Silverado ECM's. Throttle pedal is a 19417903 05-13 corvette. Engine is a 4.8, ECM is a E38
The ECM is part number 12653784 service number 12633238.
Now here is the...

Do these transmissions come with an OS loaded on them or any kind of tune? Or are they basically like buying a blank, new TCM?
Trying to find out If I can use HP tuners and do a write entire and be...

Maybe a dumb question, but can I take an E67 tune and load it on an E38 ecm?
Application is a new LS3, 495-525hp and 6l80. I've done a few vehicles with the E67 and same engine combo and got them...

The VSS connector on the GMPP harness is plugged into the OSS signal coming from the 6l80 harness. I'm also using the "speedometer out" signal from the GMPP ecm harness, that is the signal im using...

Im aware of all those details. Its still been done. Speartech did the swap on a 2001 truck.
I'm ok if I have to change the engine harness and ECM as long as I can retain all OEM functions of...

2007 express van with a 6.0 and 4l80, would like to install a 6l80 or 6l90.
Anyone been trough this? Whats it take? The vehicle is all stock, looking for the cleanest, most OEM method. Sounds like...

I'm still not getting VSS reporting in the scanner.

Just look at the pinout for the year 6L80 you have. the OSS is on the main round connector, its something like pin 14-15? I dont have the truck here right now.

The Minimum airflow should do the trick... But you need to Increase those numbers, and sometimes by 25-50% depending on the set-up.

Are you using this pace perf PCSA-TCM4410 harness? https://paceperformance.com/images/F150148893.png
I did make some gains on this yesterday. The VSS connector from the GMPP harness will plug into...

This is the transmission harness that Pace uses to hook a 6L80 up to an Erod. I see on their site it...

I will also add that when i'm driving the vehicle the VCM Scanner shows 0 mph on the speedo. The transmission is working normal and the only trouble code is for a crank relearn.

Having a hard time getting the cruise to work. Its a Dakota Digital DBW 2000 series module. Ive installed many of these on Gen4's with 6l80's and E38 ECM's.
This EROD package uses a E67 ecm, but the...

I do a lot of gen 4 swaps in vintage vehicles. Mostly use 2010-2014 E38 ECMS and 6L80 transmissions. I'm starting to do all of the programming and tuning in house and have some questions about the...

Your over looking a few things. The high idle after start up is an easy fix. There is "start up" air flow, you can adjust it based on time and engine temp.
You also need to look at the Electronic...

Check out this page. Some good info that might help you make the adjustments you need.

If you had a spark plug boot off enough to cause a miss fire and ran it very long like that it will create a carbon track down the outside of the spark plug. This will allow it to still miss fire...

So I just looked at your log file. One thing that stands out is your MAF readings. when it acts up, and your O2 readings are under 50mv the MAF has dropped into the 3-4 g/s range but your still...

This was going to be my suggestion also. You could start off by just subtracting 2 g/s of air from the whole table and see how much it effects it.

One way to figure out if this is your problem /...
