12200411 PCM, which operating system? Details inside
12200411 PCM, which operating system? Details inside 12200411 DFNN, PCM
HDW #09386530
12201281
Re-pinned for 01 GM 5.7L from a 98.
Want to use OS, 12202088 from an 01 Manual, Camaro. Is this the best choice or is there a better OS to use w/ this PCM? We plan to transfer our 98 tune (19980100) onto this OS.
Is there an easy way to transfer the tune or is it gonna be copy/paste?

I would use OS 12212156 from a 2002 over the 12202088 OS. Your not going to able to copy and paste the 98 tune over to the newer pcm and OS. You'll have to retune it from scratch basically due to so many tables being different.
Use a Van OS from a 2001 or 2002 Chevy Express van with L31 5.7L as the base tune.
Not sure what your tuning with but I see 12212156 OS for 2002 Van. They had both 4L60E and 4L80E Transmissions available with the 5.7 depending on the chassis.

they do have the 411 PCM. I think the later LS1 OSes
are a better idea than the L31, stuff like firing order
and sensors seem like a lot of questions.
I just bought a G1500 '02 conversion van and have been
poking at it lightly w/ HPTuners. Fairly normal appearing
but I wouldn't assume total compatibility to an F-body.

The reason we're suggested 12212156 is that it is very versatile, it came with T56, 4L60E and 4L80E, and DBW or DBC... (EFILive allows him to segment swap to match his transmission)... also it came in trucks and cars (EFILive provides a matrix to enable/disable various car/truck features)... and in EFILive it upgrades to COS5 (which provides tables for boost, nitrous, alpha-N)... a DBC file can be easily made very F-car (DBC) compatible.

Yah, Am not sure where I am w/ this currently. Had guys swear up & down that the 0411 is the way to go...without clarifying that not all 411's are compatible. Last week was extremely frustrating as I waded through hours of schematics & pinouts only to find a lot of conflicting data.
Here's where we are today. Have bought an 0411 PCM out of an 01 Jimmy Blazer. Have re-pinned it for an F-body. After much trouble shooting, have been able to connect to it through the OBDII port & have loaded a 12202088 OS w/ my tune. This was the OS in the PCM & had to use a compatible OS in order to load the tune. Have not yet tried to start it, but have assumed the worst. I don't think the PCM is gonna support the F-body requirements. If it doesn't, I also wasted the EFI Live licence. Will find out soon.

Verdad Gallardo Turns over, won't start. VATS is disabled. According to salvage yd, it should be compatible. Am concerned that the Blazer schematic shows a distributor. Pinned the connector for coil on plug per Camaro schematic. Not sure that the PCM will provide spark for it because of distributor/single coil compared to coil on plug.
This is some deep discussion. I am definitely no expert on this subject but some of the regulars on here tell me that the physical computer (0411 or whatever the 99-00 f bodies came with) is exactly the same. They tell me if there is an issue with compatibility, it is in the OS. I will be checking back for more expert input. I love this section.
I would think that a single part number has a single
configuration, anything else would be chaos. But the
OS could very well be deciding whether to do 8 sparks
on one coil driver line, or one each on 8 lines, and stuff
like that.
Might want a 'scope or 'noid light on each of the coil
driver lines, and each of the injector drives (because why
not) and be sure everybody's lit when you crank it, not
just one of 8 or something.

We don't have a light. Can physically check though...one @ a time. The 12202088 OS is the same for an 01 5.7L Camaro. Not sure why it's not working. I agree that the 0411 should all be the same. Just not yet sure that they are.
Could it have anything to do w/ the fact that I did not pin for the 02 sensors or the EGR or air pump? These are not required for my OL MAF tune. So, did not pin them.
What software are you using? Did you rewrite the entire PCM or only update changes? If it came from a V6 Jimmy it's going to be setup for a V6, not a V8 because there was no factory V8 Jimmy, etc., etc..
I've successfully used V6 PCM's in the past and rewritten the entire PCM to the V8 OS I wanted / needed at the time.
I'm not sure about the OS you are using, but several OS's covered several vehicles. The 12212156 seems to be the latest update on the "411" (P01) PCM's and seems to have the most features and aftermarket support. I've seen that OS in cars, trucks SUV's and vans with different segments supporting whatever the needs of the chassis are. In short, you may have the right OS, but the wrong segments to get it to light off.
EGR and AIR won't keep it from starting and I don't believe O2's are required either.

I only updated. Will try with rewrite. Came from a Jimmy Blazer, 01. Never saw the Blazer it came from. It was on the shelf @ the salvage yard. There is a common wire related to the 02's & MAF. So, I pinned one of the 02's just in case there was an issue there. Also, externally grounded the PCM. OS is 12202088 because that's what was in the PCM. Re-wrote my tune on that OS.
Checked while cranking w/ scantool & no spark. Will check again after rewrite to entire PCM. Am close to parking it until we can get a carb set up. This is more trouble than it's worth.
Anyone know of a carb set up that doesn't need a distributor...spark control through stock crank/cam sensors?

Thanks for all of the help.
Anyone who wants an inexpensive tuner, my EFI Live V1 is for sale in the for sale section. Will include the 01 Jimmy Blazer 0411 PCM that it's licensed to if you want it. I was able to communicate w/ PCM, just couldn't get spark. Probably a pinning issue; just ran out of time & patience.
A new EFLive PCM license is $125. So, the V1 can be used to tune your PCM. Comes w/ software...etc. See add.
