If that P05 came from me, it was from an 04 to 07 Grand Prix 3800SC (L32).

Mike,

Are you clarifying that this viewtopic.php?f=26&t=7637&p=121034#p120958 PCM is a P05 ??

Thank you!

Looks like a P12, but I don't think it is ... The casting around the four mounting lugs is a tiny bit different.
P08's look like P01/P04/P59/E54.

Look around on the cover, my P12's have P12 stamped in small characters near the edge by a screw.

I see, I've never seen any of them marked yet. I've always wondered where the names came from. In my stash of computers I do have one labeled as a P05 that looks the same too. I don't recall what the source was for that, but it might be a 3500 computer, bottom cover is off though so not 100% on the part number/serv number. On that one I didn't see any kind of indication on the casting besides a part number of some sort painted on the fins. I do see a couple spots that are recessed in, maybe that's where it's normally stamped? Would be neat to see a pic of the P12 stamping if possible.

The P11 was from an 03 or 04 Cavalier.

The P10 and P12 came in Trailblazers (Envoy) and Colorado's (Canyon) with the 4200 I6, among others.

Actually, yea it should be the one from you. I wasn't even sure why I had it, didn't think I bought one off ebay for any reason, makes sense now xD. I think it was shortly after I bought the junkyard computers off you when I switched over to the Toyota computers.

To add, pretty sure 05 Cavalier also had P11, and the one I have was ecotech, I don't recall if both versions of the engine came with the same computer or not. It's kind of funny, the GM stuff has a bunch of numbers that seemly are random, switch over to Toyota and it's pretty intuitive. Like 1MZ is the 3.0L camry v6 engine, later on it was redesigned as a 3MZ 3.3L. There's several more computers, but they physically are pretty easy to identify, 94-95, 96 (for derby reasons also works with 97-98), 98-01. Only real changes was the ignition system aka number of coils, started off as 6, dropped to waste spark with 3 then the 98+ one the physical connectors changed which is also when they introduced immo and the ability to have traction control. Might just know these computers better since I've been working with them basically nonstop for a year though lol.

For the sake of being 100% accurate, here's actual photos of mine, the orig pic is from ebay. Looked at my notes, I guess I also have the BDM pins for P05 too lol. My notes says they are based on P11 locations and I have a bin file so the pins should work. I know I didn't get into them too deep, but looks like I was working with Ghidra a bit with the P05 bin a bit lol. I doubt I had much worked out though, maybe really simple things like coolant temp, air temp. Don't have that installed either, not sure if they have a Linux version, if not I'd probably have to setup a VM if/when I get back into these.

Gampy, as that ECM is for a 3.5l LZ4 THIS would be closer:
06+ Chevrolet Impala, Malibu, Monte Carlo / Pontiac G6 / Buick Lucerne / Saturn Aura 3.5 LZ4/LZE, 3.6 LY7, 3.9 LZ9/LZ8/LZD/LZG (E37/E38/E67 ECMs)
So No, I do NOT think it is a P05 though they are similar much like the P01, P04, P08 and P59 are similar.

Mike

p.s.
Hopefully when the local GY has a sale I can get a few more PCM/ECM units to play with.

I think you are correct according to this:
97-05 Chevy Cavalier, Malibu / Pontiac Sunfire, Grand Am / Saturn L-Series (00-04 only) 2.2 L43/LN2/L61, 2.4 LD9 (P08/P11 PCM)
The L61 is the Ecotec 2.2l, so it should also use the P11 in 2005.

all the information on the pcm's came from here:

How do you get to the chip side when taking apart a p04? the pins are epoxied in. I did get a borescope in there and found i had an amd chip on my 2004 grand am gt board.

What do you mean epoxied in? The P04 has legs on the cpu and the flash chip. A photo probably would explain what you're seeing better. You're Grand Am computer is probably the same hardware as a Malibu since you have an AMD flash chip.

For taking apart the P04, just have to remove the 4 torqs screws, tap the bottom cover off and that exposes the bottom of the board. 4 or 6 more torqs (different size of course because it's GM) and the board pulls out. The two connectors on it stay with the board and the silicone gasket goes all the way around it, so might be a bit hard to pull up. Once it's free, flop it over and you can see everything. There's a few different colors of the silicon, white, orangeish red/brown, and gray are a few if I remember right.

[DethRattles]

I took the 4 torx off and the smaller inside,, i felt the board would snap if i pulled on it. And the pins I'm saying that are epoxied in is where the connectors go. I felt like gm slid the boards in and epoxied them and the inner screws were just like support. I then thought you knew where the chip was so you'd drill a hole on the outer case over it and peer in...

[DWS]

Nope, just pops right open for me. I've opened up around 8 or so P04's.

The P11's and P05's are glued together with a sort of thick silicone type of glue plus the actual connectors for the harness are soldered to the board and has to be desoldered to pull the board, but those are for a different car/engine.

Here's a couple pics of a P04/P01/P59. Pretty sure it's a P04, I can see the Intel flash chip so probably from a W body, I got a hand full of failed W body flashed computers (bricked) that I wanted to try to recover. A lot of the hang up for pulling it apart is at the harness connector side.

[DethRattles]

I see now ,,i was pulling down on the board slightly enough to get the borescope in...i got lucky then with seeing that amd chip with my borescope. One day i will learn,,,baby steps with clubbed feet
