Pull the fuses for the radio and navigation if you have it. I had the same problem on my buddies 06 H2. I was an idiot though and tried a write entire before I figured out what I was doing wrong and...
Keep in mind once the VIN is changed you will probably not be able to edit the program anymore with HPTuners. Something about not being a valid combination...
You can also short out pins A and B on the ALDL connector and get codes, or you can look into Moates hardware and tunerpro software to get actual data for around $100.
Do you have anything else hooked to the data line. my 2003 will act like this when the radio is turned on, I suspect it has to do with the adapter that interfaces the radio to the factory harness. I...
I have gotten wrong information from Autozone, I would not use them as a reference for anything other than pointing you in the right direction.
Don't change the VIN number unless you absolutely have to, it can cause licensing issues and you may not be able to modify the tune again.
If your PCM is one of the Green and blue PCM's that have...
lt1swap.com has a ton of pinout diagrams.
I had a similar issue with my 99 Suburban that is running the same tune my 4.8 silverado is (I am running coil near plug ignition) Anyway, my A/C was doing the same thing and the only thing tat got...
Thank you.
They are just the factory injectors from the L29 believe they are 19lb/hr @3 Bar.
I am running an 0411 with the OS from my 02 silverado. I believe it is 2156. I'm running 8 coils and the crank...
I would like to get a copy of that file. I have already set up the truck, but am using the 24 tooth reluctor wheel from the L21 and CNP.
Just having a better file to pull injector data from...
If you are seriously asking... For F**ks Sake...

Has a list of which service numbers have the IAC drivers.
There is another way to use a truck tune to manage the fans and the compressor. You will need to have the truck licensed, you will also need to get the A/C pressure sensor from the later model truck....
Does anyone have the proper injector data to run with a 2156 OS? I have the truck up and running, but it idles a little rough and stumbles off the line. I haven't tuned the VE table yet, or even...
Depends on what vehicle, most are just 2 credits, some are 4 and there are a few exceptions.
You should be able to read that PCM with the scanner, you just can't make any changes to the tune.
You mention that the distributor was worn and I imagine replaced. You can't just set timing on...
Good to hear
More of what I meant was...
A question first...
Is the car running a stable tune? even if it isn't perfect?
If it is, then you can hook up the MPVI to the car and "read entire" and save...
There is no harm in having the RTT, and it is reversible as well. Just follow the directions posted above. You are over thinking it.
I know it is scary, I had a lot of misgivings about this as...
I'll be honest, you are the first person I have heard of that has done this swap and been unhappy with it. I would be interested in seeing the tune you were running.
My buddies 2001 Suburban with a 5.3 is drive by wire, yet my 2002 Silverado with a 4.8 is drive by cable. So you may still run into it.
Is it running any better
I don't believe you can swap segments with an OS mismatch. I would run the 2002 K1500 file that has been segment swapped to run the manual. You will need to make sure the new tune file (whatever you...
The only thing I have to offer is the question. Did you change to a different transmission in the settings or did you do a segment swap? You need to do a segment swap for transmission changes, the...
