We now have Pin-Out diagrams for several model Ecotec ECM's. Follow the links:
02 Alero
02-05 Cavalier / Sunfire
03-? Ion
05-07 Cobalt LSJ
05-06 Cobalt L61
06 Solstice
07 Solstice
02 Alero
02-05 Cavalier / Sunfire
03-? Ion
05-07 Cobalt LSJ
05-06 Cobalt L61
06 Solstice
07 Solstice
And who makes the P12 PCM for GM?
Thanks

so if i was to flash the TCM with my VIN , and repin my 05 LT A4 harness for a 2.4 PCM...whats to stop it from working???
I really wanna use my HPTuners to tune my Cobalt ...

there are those of us that would prefer to tune our cars ourselves....and not worry about going back and forth and dealing with another party. so if he is able to do it let him. if not o well

The LE5 engines don't use a PCM.
The E67 software is not compatible with the other CAN BUS items in the E16 cars.
You will never be able to use HPT on an L61 engine. HPT will not support it.
Get the AEM F/IC. Then get Trifecta to make you a tune that will allow the E16 to play nice with it. That way you only have to flash your ECM once, and can still make changes at home via the piggyback. That's how I plan to do it.

Imeant the new TCM from the donor.
What? What does it use then?
Well aint that a bitch....What CAN BUS items are we talking about?
Does anyone have any experience using the AEM F/IC? Man HPTuners really makes it difficult for us 2.2 guys... I just wanna turbo the darn thing lol. HPTuners is so dang easy to use...I really wanted to use it on this ride.
Im going to check out that AEM peice...Ive never used a piggyback before thats why I just wanted to stick with the HPTuners but I guess its good to learn new things.....

You need to do a lot more reading of that topic here on this forum. It was covered extensively back in 2005 when the L61 and LSJ cars first came out. You can't do it. The ECM's in these cars are each individually so different that the rest of the car can not function without it's original. Don't think about the ECM as a stand-alone component, because it's not. It's a part of a complete system of operating modules that are all connected together via a network. ABS, BCM, TCM, many more, will just not communicate with anything different then what was originally installed.

i think jimbo meant, what if, we took all the abs bcm tcm ecm ecus etc etc. out of a 2.4 or 2.0 and put all those components and wiring harness into a 2.2 theoretically it would have to work? yes its alot of work but it would have no choice but to work properly and then tuning with hpt would be possible

I know exactly what he meant. And for the cost of doing all of that, it's cheaper to just trade in the car for the right one to start with. I'm not being a smart ass about that, it's completely true. And nothing but the E16 can run the L61 engines in the 2005-06 Cobalts because of their unique ignition system.
#63
instead of switching pins on the ecm's and swapping engines, it would be easy to get a j-boby ecotec moter and ecm with wiring and drop that in, all you would have to do is install the cable throttle body....

Yes this link confirms 2007 ion2 says about e67 pcm https://en.wikipedia.org/wiki/Saturn_Ion look under the heading in bold 2007. Here is a pic from hotrodmagazine showing a e67 pcm Know Your E67 ECU - Hot Rod Network
It increases the HP and TQ so next is who can test this pcm on a 06-08 LE5 that way we can do the swap
also another question does the 2007 2.2 Ion2 use a 58x trigger on the crank ? I thinknot

Thanks for the reply and update Slowbalt2000. I am new to this site and just tryna learn and then decide how to go about doing the swap. As for your question I would suspect the compression ratio goes up or the VVT LE5 head increases the hp/tq on the stock 2.2 ecotec (L61) or both. For now I am looking at upgrading to a 2007+ 2.4 LE5 engine for starters.
I think the engine upgrade would be plug & pray, what do you think ?

The following is a list of the different computers used in different Ecotec installations. Pin out diagrams that I could find are lower in the thread.
Notes:
"PCM" Powertrain controller, which can operate an engine and transmission. Computer starts with a "P"
"ECM" Engine controller only. Computer starts with an "E"
"TCM" Transmission controller. Only in vehicles with an automatic transmission. The device is a slave to the ECM. In manual transmission car, the TCM is not installed.
J-bodies:
2002-2005 L61 equipped cars:
PCM: P11
Deltas:
2003-2006 L61 Ions
2005-2006 L61 Cobalts
ECM: E16A
TCM: T42
2007-current model L61 Cobalts, Ions, G5's
ECM: E37
TCM: T42
2004-2006 model LSJ Ions
2005-2007 model LSJ Cobalts
PCM: P12
Note: The P12 unit could in fact operate a transmission in this application. It is simply not used. However, somebody using HP Tuners on this computer will find variables for it on the 2005-06 cars. In 2007, they removed those variables.
2006-current model LE5 Cobalt, G5's
ECM: E67
TCM: T42
2006-current model LE5 Sky, Solstice
ECM: E67
TCM: ? (5L40E trans)
LNF Cars:
Sky Redline
ECM: E69
Credit to Witt and WopOnTour for some research notes.
All of the above computers are supported by HP Tuners except for the E16A. The E37 and E69 are in beta test right now, but not yet available in public release. The E16A is reported by HP Tuners as being scheduled for support in the first half of 2007. It is also reported to be supported by SCT Flash as part of the Garrett turbo package release in first quarter 2007.
