Wanted: LS1b 1220411 OS 1221256 Disassembly?

[EagleMark]

Does anyone have a dissasembly started for MY 2002 PCM 1220411 with OS 1221256 ? Or can someone run one through so we could start?

This would cover all 1220411 possibilities including the Vortec Engine as well as LS engines.

We have one for MY 2001 PCM 1220411 OS 12202088 . This one does not handle the Vortec Conversion and is not as good as above.

got a BIN?

[EagleMark]

Yup!

[RobertISaar]

not sure what's going on, but i seem to be having quite a difficult time getting it to disassemble correctly.... using the same settings as i do for the 512KB V6 BINs, i get nearly nothing to disassemble. with the V6 stuff, just the reset vector alone gives up a LOT of the code instantly.

Hey guys ... couple of things. As you already know, the 2001 and 2002 Express / Savana vans used an 0411 PCM to control Vortec Gen I style engines. They used a couple of OS in 2001, including OS12208322 ... which is what you need. In 2002 the only OS was 12212156.

I have a *.cal that may help ... it's an L30 5.0L 4L60 from a 2001 Express.

Thanks Buzz! But that is the OS/diss/XDF we already have in the other thread listed in above post. I'm trying to get started on the 12212156.

... We have one for MY 2001 PCM 1220411 OS 12208322 . This one does not handle the Vortec Conversion and is not as good as above.

OS 12208322 or OS12212156 will work equally well for a Vortec 0411 conversion project. If you are stuck, and need to move a project forward, then use the 2001 OS. If the original intent of the thread was R&D ... no worries ... I have every confidence you gents will get it figured out.

[EagleMark]

It is R&D... but I didn't know there was a 2001 Vortec 1228322 OS cal! Just need to turn that to a bin. That means the 0411 swap is capable with a Moates Roadrunner and TunerPro with files in above thread!

Here is an 2001 5.0, 4L60 and a 2002 5.7, 4L80 in .bin format.

We need to take a collection and buy Robert IDA Pro... or a key generator...

[EagleMark]

OK Hows this look for a 1220411 start?

And the 12202088 for comparison?

[RobertISaar]

We need to take a collection and buy Robert IDA Pro... or a key generator...

.... why would i need? i've been running IDA Pro for probably 3 years now.

[EagleMark]

D'oh!

No idea what you guy's are talking about disassembly/ida pro wise but how can I help?
I've got TCII,EFILive,TP,TT,a Bench harness and a couple 0411's to play with as well.

[EagleMark]

.... why would i need? i've been running IDA Pro for probably 3 years now.

got any time to try that again? Is it a differant processor choice or? I've tried with IDA free but not having much luck...

The other one I found above titled 12200411.asm is not much help, totally differant then the 1220288 layout.
