Intake is from a 2000 yukon. still searching for the fuel trim problem. thanks for the look 5fdp!

We have swapped a 2001 5.3 into a k5 blazer. it has a muncie sm465 manual transmision. the ecm has no speed reference. it runs decent, still working some bugs out. Will it be ok without the speed...

I figured out that vcm scanner wasnt turning off the injector it says it was. i borrowed a tech 2 and when turning off injector 1 it actually turned off number 1. Went all the way around the world...

Our GM parts catalog (dealership catalog) shows the 09354896 PCM compatible for up to 2000 model year. But cant see how that would matter if the tune is also a 2000.

Thanks for the schematics. I have access to Service Information as well. Wiring is correct on the injectors to PCM. I must have either the wrong PCM or wrong calibrations for that PCM. I just dont...

Working on a 2002 5.3. transplanted into a k5 blazer with manual transmission. PCM is service #09354896
Engine runs decent but has loss of power and sounds like a misfire. (Also misfire counter isnt...

Did you ever figure this one out? I have the exact same problem.

I wonder if it's inherent to the 0411/ l31 (5.7 vortec) pairing? With the compare feature I wouldve only gotten calibrations I think. Wouldn't I be looking more towards the operating system....not...

yes they suggested loading a different tune. they suggested if i had a stock tune to try it. i didn't have one so i found one in the repository and apparently had it open in editor (which i thought...

I know this tune has had misfires read with a mpvi1 last year.

here is the tune file

Any ideas anyone?

Looking for a clue guys. Mpvi2 , vcm scanner when logging the misfire counter is staying on zero therefore I believe I can't see any misfires (which I believe I have). I've set it up with current and...

thank you sir

2014 gmc yukon 6l80e. mpvi2 , Im trying to set up layout in scanner to view what rpm and speed shifts are happening. any suggestions or layouts are appreciated

I did the 411 swap a month ago and its running great. The swap didnt take too long 4 hrs or so. Thanks to Lextech, he hooked me up good!!

Thanks Shrek. Ive been looking for a detailed guide on the 0411 swap and I cant find it again. Do you have the link handy?

No sir. I don't plan on tuning it myself.

OK. Does anyone know what's involved in a 97' to a 98' PCM swap? Are there any write-ups on it? I don't need any of the security or emmisions stuff.

I have a 97' Vortec 5.7 in my 86' k10. It came from a friends show truck who upgraded to a 6.0 lq9. He had a supercharger on this engine which i didn't buy. I've ran the truck a few hundred miles but...
