Not sure what OBDII system to run for the F-body crowd. It would have to be something that did the 4T65-E since that has electronic line pressure.

my 97 Venture ECM will control a 65E, I just need to figure out what pins go to the pressure solenoids, it has the tables there.
And I was referring to you when I said OBDII ftw...

You wanna come help chisel the sealant off the engine bay through body harness connectors that have 10lbs of sealant on there? Probably need a plasma cutter. I have those things sealed up like there is no tomorrow from when I was tracking down my water leaks in 05. I don't even want to think about disconnecting that crap! But regardless,OBD1 for me is cheaper, and easier to implement. Less than $200 for all the hardware & PCM. And less stuff to install. I won't have to get new engine harness, ABS computer, master cylinder, glove box, air vent, MAF, etc. That's less work to install and less cost. Just a DHP alone sold on 60degree for $250 which is more than this whole project will cost me.
All I'll have to do is solder some wires (cake compared to what I usually solder) and plug it in.

Plus that means if I do a 3900 swap, I don't have to worry about the 24x and cam sensors not being there, just one external trigger.

If it's the same as a W-Body, then it's connector C2 pin 61 (high) and 20 (low)

Still need this PCM? I happened to come across a spare.

Not worth the 50-75lb weight gain... I can use some stronger 65e parts in my 60e
Hell, I think I'm downgrading to 11" rotors this winter to lighten up all that crap... 12's are nice but DAMN they are too heavy.

Hehehe. Yeah weight adds up fast.
Cliff: Actually I got one from Jay on 60degree. Got the connectors out and ready to go. Didn't feel too guilty since this PCM was under the hood and had leaked water inside at one point, the traces on the PCB were bubbly and the aluminum case was corroded on the inside too. Both the rubber seals on the case and knock filter access panel were compromised.
