Any chance this GM PCM can be tricked into controlling a Mopar OD trans?
Kevin
I assume you are talking about lockup and shifting OD ?
I was wondering if it could control an RE trans as in 1 2 3 OD and lock up.

The only shifts that are controlled by the computer are OD and lockup. 1-2-3 are not really electric controlled, the E is for the electronic governor.

I spent tonight working on a PINOUT chart for the wiring harness. There are many on the internet for making a standard standalone LS wiring harness, but I wanted to simplify it for everyone and show everything that can be removed for use in our mopars. I spent dozens of hours figuring out what I needed to keep and where everything needs to be hooked up. So, I plan to share the fruits of my labors with everyone so you don't have to. Also, This could be applied to SB mopars the same way if someone wanted to. Some things to keep in mind, the harness will only end up being about 1/3rd or less of it's original size once you strip it down to a standalone harness. Also, the EASIEST way is to start with a LS1 1999-2002 F-body (Camaro/Trans-am) harness and use an 1999-2002 F-body based tune. The truck harness's are cheaper (I paid about $75 for mine), but some wires are a little different and the truck O2 connectors are different and will have to be changed to F-body O2 connectors as well. I will not go into using truck tunes or using all the various truck o2 sensors as I didn't fully research this as there are many different truck o2 sensor configurations and I wanted to keep this as simple as possible. So, you can use the truck harnesses with additional effort, but just be sure to pin/wire it according to the chart I will post later (hopefully I will finish it in the next few days).

really awesome work. keep it up. i'd be happy to lend any machined parts needed to the build. custom distributor pickup for cam sensor, perhaps.
Thanks Jerry! I really appreciate that....I'll let you know. Even though I have my one working Cam sensor already (Still needs a blank cap for the distributor though), I'm working on using another existing cam sensor from a Jeep that could be almost a drop in as it has the proper shaft on it already that should fit the oil pump drive. That way people can replicate what I've done more easily.

I may have this done before you do!  Have been working on this exact setup all last week.

The only shifts that are controlled by the computer are OD and lockup. 1-2-3 are not really electric controlled, the E is for the electronic governor.
I just looked into this, and I don't believe the GM PCM can control the governor on 4xREs.
"Duty cycle on the Pressure Control solenoid is inversely proportional to the throttle angle (as throttle angle increases, duty is decreased) At idle (minimum throttle), the duty is at max (60%). At WOT (wide open throttle), the duty is at min (0% or off). Note that the PC solenoid takes the place of the Throttle Valve cable on earlier transmissions. "
I think it could technically control the RE's governor pressure solenoid, but the GM PCM doesn't have a (stock) way to read the governor pressure and adjust the output PWM accordingly. I don't know how much flexibility their tuner software has to add inputs and do software filtering and custom control of outputs. So, I think it's unlikely it would work.
Guess I'll continue my project to make an RE controller 
If you ever find yourself in a fair fight, your tactics suck.

BTT... I've got my harness almost finished, Just have to get all the pieces for the fuse block and relays. I've followed the instructions and pin-out charts on www.lt1swap.com. This page makes it a breeze especially if you are familiar with GM factory stuff. I will try to post pics of my harness this weekend when I get it all taped up. I'm going to try to get to the JY friday to get the parts to build the cam sensor pickup. I've got a GM 1X sensor I just need the reluctor and adapt it to an old distributor. FWIW The drive-by-wire stuff is all pretty much self contained into one connector and gets rid of the IAC and TPS. I like the idea of being able to place the TB in any position as my inlet from the intercooler comes in over the pass fender. It will make TB upgrades more expensive but it looks to be atleast 70mm so I think it will feed all my engine can take. Also the later 2005 harness I have also integrates the IAT into the MAF sensor.

Redmist....did you try to use the complete Jeep cam sensor in a RB/B block? I ordered one which should be here this week for under $50....looks like it may work if the shaft is long enough and If I remove the gear....??
Yes I am sir!!
The shaft is in fact long enough. All that needs to be done, is a bushing made to simulate the stock distributor, with a hole in the middle to hold the factory Jeep cam sensor. Even the factory distributor hold down will work. The gear on the Jeep sensor can be left in place, ans it holds the gots of the shaft, and it will just float in the block out of the way. The only modification to the whole jeep part is a little bit of cutting down of the keyed portion on the bottom of the shaft. I am going to run this part on the lathe this weekend. I can build you an extra if you want, it will be a CNC Program, so all I have to do is press cycle smash to get another one. 
I am using the MS3X in full seqencial mode on both fuel and spark
36-1 trigger wheel off the crank, and the Jeep sensor for Cam. Spark will be coil close to plug using LS2 Truck coils.
Here is a small video I made tonight with an overview of the MS3X I built, and the Stim boards I built for testing it:
I will most likey start my own thread so we don't detract from the LS CPU route though.

Awesome man! My sensor is supposed to be here tomorrow. Yes, that would be great if you can make me a bushing too. Just PM me what I owe you for it.... I like the Jeep sensor since it's clean and smaller too.....
Did you find a harness connector yet that fits that cam sensor? I found this one that I think will work...kind of expensive for a connector, but should make for a clean install (let me know if you found a cheaper or different one...it's $26 on rockauto:
AIRTEX / WELLS Part # 1P1715 for a 2000/2001 Jeep Cherokee/Wrangler 4.0, is that the sensor you used?

Looks like Chrysler cloned Fords cam sensor.. 
Very similar, except the jeep one's shaft is shaped correctly to engage with the mopar oil pump drive.

I used this sensor:
http://www.summitracing.com/parts/rnb-689-200
As far as the plug/pigtail goes, It looks like the standard 3 pin used on the Jeep CPS is the same thing that is used on a bunch of other brands for alternator connections. I am going to hit the parts yard for it, and my injector pigtails.
Damn I am a cheep [Edited by Moparts - Family Friendly Site - Keep it clean]!
