What to do?? The (2002 Express Van) 411, OS 2156 PCM states it is a 4L80E, yet I would like to change it to a manual NV3500. The engine is a L31. I am utilizing TunerPro & OBDLink LX.
I have a .ctz...

Hello! I am having a AWEFUL time tuning idle for this. Where could I find this Mexican .bin file to simplify my LIFE!!!!!!

Hello! I have been unsuccessful in the attempts of seeping the PCM. You mentioned the Mexican 5 speed. Is it a .bin file?

Will I need to pin the PCM the same as a 02 Silverado perhaps maybe???

Thanks Dave. Good read. I need to figure out how(pin) the wiring of a 96 clutch switch to the 411. I looked on my Identafix and notice the same clutch switch is use in 02 trucks. Just gotta follow...

Thanks! Did you get the SECURITY key figured out?
As for me, I utilize the LS droid & Tunerpro. This is the first Experience I will have with PCM/ECM at this level. I believe I have all the needed...

Awesomeness. Yes yes, I'm putting the L31 from an 2002 1578315784Express in to my S-10 work truck and would lile to stick to the manual transmission.

Awesomeness! Thanks! ?? Link above... Do you mean #9 or #11?

OK. I will read this 2 to 7 times to get it to soak in. HUGE THANKS!!!! SO, I have the L31 5.7, yet I need to pick the parameter files from the #11 post. I must not be understanding!, for it is a 6.0...

I know not what to do! Dave what should I do? Am I able to copy partial .bin files to the one I have? Is that what is called a 'segment' swap? Thanks for any and all guidance!

Cool, Awesome SITE!!!
I found the .XDF, however I noticed in the TorquePro RT "transmission type" it stated ** this parameter should NOT be changed ** !!!
