What a great Chart!!! Thanks for sharing HOG

I don't see the LM4 and the L33 Aluminum 5.3L listed on the chart.

Looks like there is an 04 SSR for an LM4 OS and a 2005 GMC with L33 in the tunefile depot.

Minor update to include the SSR. Also tried to squeeze in a few more RPO codes and a quick description. As usual, if you see anything missing or any errors, please let us know.

Thanks,

I wanted to add to this tread, as there is some very good info in here.

The 2004-1007 Ion Redline and Cobalt SS used the P12 PCM and were 100% 58x. I am working on an E67 swap for my 2007 right now, and verified the reluctor wheel is 58x at a local machine shop where one of these motors is in for work. I had it in my hands, and it is not a 7x.

This was brought up to me a few weeks ago as well, unless the P10 is 58x as well (doubtful, was released in 02 and Ive seen 02-05 I6 reluctors, they're 7x) then it means at least the 06 P12 can run BOTH 7x and 58x setups. It is OS dependent at that point, the I4/I5s were either all 58x or the Atlas engines were 7x and the Cobalt/Redline ones are 58x. I know for a fact the 06 P12 can run an 02-05 I6 which is 7x using the TB/Voy OS.

From what i understand they run both. I do know the Cobalt reluctor wheel is clocked 30 degrees delayed and uses a different sensor than every other car. I want to do an E67 swap for the tuning ability, since the P12 is missing so many tables. The crank sensor part is the only thing holding me up. The E67 ran the 2.4 Cobalt SS cars, so besides the crank sensor part, it should work.

Im not sure where the 4cyl cars get their crank signal, but worst case you could fab a 58x reluctor wheel and put it on the crank dampener (if there's room). Mount it externally to the engine then you could use the E67. Not sure if that'd work for your setup, I havent been under the hood of a Cobalt SS.

Can this thread be cleaned up? I used the list from the first page and it is wrong as far as the e40 ecm is concerned. The correct list info is not fully correct until page 5 of this thread. Just maybe eliminate all the previous files until the last one.
