I totally agree, but I sorta had to do this since there is no such factory DBW Vortec 5.7 tunes. Or, really, how much of a factory LSx tune can I keep stock to run the 5.7? I basically kept all...

I think I posted the wrong tune...I did in fact correct those tables you mentioned though.

Yes, stock MPFI spider.

Thanks for the reply!

I've been trying to tune my truck lately without any success. I've got a '02 ZR2 Sonoma with a Vortec 5.7L. These are the main mods I'm currently running.

Vortec 5.7L engine with 24x conversion...

Great! Thanks!!!

I'm in the same boat as the original poster of this thread. I'm running the 12200411 PCM and the 12209203 OS. My setup is a 24x conversion on a Vortec L31 5.7 and has DBW, LS2 coils packs, and just...

Yes, its been running for almost 3 years now on this setup. I am using the '02 LS1 PCM that came with the V6. I actually thought about using one of the Vette tunes...could I still have 4WD using it?

I've got a Vortec 5.7/4L60E in my 2002 4WD truck (Sonoma ZR2) that I am going to mod with EFI Connections 24X reluctor and add the LS2 coil packs. No problem doing this...but now I would like to add...

No, it must be mounted before the cat.

Figured it out! Was the darn fine/course control setting I forgot to click on. :doh2:

Ok, I'm trying to get RTACS to become active in the tune tool, but I can't seem to get it. What will get this enabled for me? All the other data is present in the RTACS boxes when doing an AutoVE,...

I did a similar swap in my '02 GMC Highrider ZR2. I put a crate 5.7L Vortec in it and it is currently my DD and has almost 25K on it.

I recall the same issue with mine and another persons PCM I...

Just an FYI..

Paul sent me a patch that seems to have fixed things for the moment. However, Paul and Craig are discussing features to make the option of 512K or 1MB much easier and smoother to...

Oh really? That would be nice.

I tried a full flash and read again, holding Ctrl+Shift and I'm still getting that unknown bin file format when I try to read the file back out.

Paul,

I haven't had a chance to actually hook this up to my vehicle yet. I'm running it on a bench-top harness at the moment, but I also suspect that it will not run the engine if I tried.

Email sent...

Thanks Paul, that worked!

But when I try to read the tune back out after flashing a 512K operating system/cal, I get a message that says "unknown bin file format". Is there a way to completely...

This was a guts kit that I installed. I definitely have the 99-02 PCM with red/blue connectors. The first two digits of the RR serial is 02.

Based on the other thread I linked, how are others...

Hmmm, then why is the already assembled Moates 12200411 PCM listed as a 512? I'm confused :doh2:

No, this is a 512K PCM running the '02 Express cal. I was under the impression that this 1MB emulator worked on either of them. There is no option on the Moates site to select which one you want so...

Ok, I just got the guts kit installed and it connects just fine. When I try to flash an operating system/calibration in, this is what I get... I thought I read that the 1MB emulator will work on...

Thanks for the notice. I just picked up a guts kit. :mrgreen:

I may be interested in this, if you still have it.

I was afraid of that happening...looks like I'll need to find a used one then.
