2013 Cadillac ATS 2.0L..

Is the ATS using the E39 ECM? Has anyone even seen one to attempt to take a scan from it?

I believe it is Adam, but no reads have been submitted for support yet.

I'm EXCITED about thisss! An awd CTS with a Cobalt SS engine... like

Boost, Not quite the SS engine. The LNF was updated to the LHU found in the Buick Regal GS. The engine in the ATS is a LTG and little of it is the same. I suspect a lot of the internals are, but the intake and exhaust tracks are reversed now and the head and timing chain cover are totally different. Some of the limited specs I have seen around mention a canister oil filter and composite intake manifold too. Almost sounds like we're going backwards..

a canister oil filter

What the? Looks like someone's grandpa paid a visit to GM engineering.

All VW/Audis have canister oil filters, I scratched my head for a minute when I changed the oil on my brothers 08 VW Jetta.

All VW/Audis have canister oil filters

That still doesn't mean it's a good thing
You might find that if European manufacturers are heading that way then the GM engine was probably designed in Europe. Actually, I've never looked on the Cruze 1.4L to see what it uses, that engine was designed in Europe.

Yeah all that is true and I was generalizing / exaggerating about the SS but you get my point. Seriously can we PLEEEASE confirm that all these are supported E39???? Even the Buick versions.... I forecast a war with a certain nazi tuning company that think their minions will control all the 2.0 market LOL little do they know the E39 switch puts a lot of regular folks back in the game

Competition is great for business and development, enjoy it while it's still legal :s

OMG! Tell me about it! Had things been different and I actually has some say in the purchase of our family sedan I would likely be all over the ATS, but it was my wife's decision and we are now 328i owners. I Like the car, but the cost of aftermarket is just stupid and honestly my wife and I argue over who drives the 2007 SKY more than the 2012 328i..

My only concerns is with the overall strength of the new motor. Some GM docs show the rods as Forged powdered metal vs. Forged Steel. I suspect the initial data is for the 2.5L motor, but the 2.0L has forged steel like is the case with the LE5(2.4>) vs LNF(2.0L).
Also on the GMpowertrain.com shows an image of the new engine and you can see in fact it does have a blue canister filter near the exhaust manifold at the bottom of the engine. Also if I can find it somewhere I saw that the Modular balance shaft system was in oil pan rather than part of the main block like the rest of the ECOTEC blocks.

I would say with 99% confidence it will be an E39, but, as this is a newish ECM in a new model year I don't know what changes they might have made. What I mean by this is like on the T43, GM made some changes to the memory layout that threw us a curve ball in 2010+ models.
