I hope these 4 pages get to message.
I got PC back up tonight, but couldn't get scanner to combine all 4 pages into one pdf.
My PC with the scanner took a dump last night and I've got to get another motherboard.
If you want me to mail pinout to you, PM me address, and I'll get it out in the morning.
It might be a couple...
I'll try to get done this weekend.
I can print out today at shop, and try to scan tomorrow at home.

I can do a Mitchell wiring printout and scan it to a pdf if that would help.
You can get trans shift kit from B&M and others. Check Summitracing.com.
You should be able to use the 03 4.3 flash after disabiling trans stuff.
I'm glad you got it together Mike.
It's time the LT1/LT4 got a fair shake.
You're cool now. To use the pcm, you need to make sure it is a 5.7/4L60E or whatever engine/trans combo you are running.
Some of those trucks had 4.3/4L60E,5.0/4L60E, and also 5.7/4L80E combos. ...
Here's the list. Check Delco link.

Once you re-flash, your vin changes to what you flash with.
Here's the list of vehicles that used the 12200411 PCM.
Easy to find in junk yards.

Really good looking numbers.
That's really good info to know.
A lot of the LT1 stuff was re-used in the Vortec and Ramjet tech.
The cast iron head and big car cams are also basically same.
I guess the pickup is in same location or do you have to rotate reluctor ring to correct angle.
Mike, is the LT1 and SBC same timing cover pattern?
I've never been into LT1 engines, even though I run LT1/LT4 cams in SBC Gen1 engines.

I think someone told me that they turned off torque mgmt.

You might want to get hold of www.eficonnection.com. S10Wildside helped me with changing L31 over to 2002 12200411 computer.
He now has figured out the reluctor and has a Ramjet engine running with...
Great work S10!

Dale, is the part number different from 4.3 to 5.7?
Ron
I've gotten a couple of those from Howell Engineering over the years. They do work.
With the 400, he needs to run a 2.73 or so, even maybe a 2.56.
Lots of the camaro/nova rears from that era used...
Are you on the Caddy engine now?
Tunercat OBDI works pretty good and reasonable. I use it.

You probably want to look at Tunercat OBDII, which is sold by JET now.
