Does the 2010 CTS wagon with 3.6 liter engine which has direct injection use the
E69 #12617230 ECM ?

And if so does any of the laptop type tuning tools like LS2edit support this PCM ?

Or does it use like a E38 or E39 ECM ?

This correct ?
If it is an E39 it should say ACdelco and E39 on the white label.
If it is an E69, it should say Bosch on the label.

Pretty sure it's a Bosch .... but don't know anything about laptop tuning tools that can talk to it? If any can, that's interesting.

Thanks for the reply, anyone know where the ECM is located ?

Thanks for the reply, anyone know where the ECM is located ?
behind the driver's headlight ... mounted to the frame (i think)

The ECM is behind the drivers headlamp

For 2010, the 3.6L SIDI (LLT) is an E69 and the 3.0L SIDI (LF1) is an E39 controller

EDIT: Looks like Rippy beat me to it :D
Also: starting in 2012 both the 3.0L (LFW) and the 3.6L (LFX) use the E39 controller

i've got a 2008 cts mpfi. recently getting crazy fuel injector codes. #1 #3 and #5 fuel injector open, #1 #3 and #5 injector circuit low, #1 #3 and #5 injector misfire, random misfire...car runs like S*** obviously, i bring it to the dealer and of course it runs fine on the way, but he pulled those codes. i'm curious if there is a fuel injector control module that may be going bad, OR if the BCM/ECM do the fuel injector controlling?

Never mind... 00blue beat me to it...

Hi all just bought a 2010 cadillac cts performance package, quick question not sure If a bulb is blown or not.. The area where we go from drive, Park at the center shouldn't it be a light there,?

Ryanramkissoon86, welcome. Feel free to search and you'll find a lot of good info. Your question was asked and answered many times, most recently here: http://www.cadillacforums.com/forums/2008-2013-cadillac-cts-general-discussion/445217-light-shifter.html
Try some searches, it's easy. Oh, try not to ask off topic items in threads....this doesn't have anything to do with the ECM and you may not get many answers....plus it doesn't help searches if topics are mixed up.

Your vehicle has a Bosch ECU... We provide tuning solutions for this platform.

noshelter, did you ever get any replies to your injector questions?
We have a 2009 CTS, 3.6 V6 Direct Drive. Low miles, 38000, and we've replaced injectors 3 times so far. First time was 1 around 10,000 mi, second time was 2 around 22,000 mi, now it's 2 more at 38,000mi.
At 38000 its out of warranty.

Geezus, talk about a thread hijack! WTF is this thread about? I thought it was all about ECM, but what do I know?

04-13-15, 11:20 AM
Well if you need to get this thread back on track here you go... for the 2010 Cadillac CTS 3.6L Direct Injestion used the Bosch ME962 ECU Type, from 2008-2011 the CTS with the DI engine used the Bosch ECU LLT 3.6L DI Engine, in 2012 it was replaced with the Delco ECU LFX 3.6L DI which is still currently being used in many GM vehicles. Note: Early 2008-2009 CTS also had a optional 3.6L MPFI LY7 engine (multi-port FI) non-DI 3.6L

I thought the OP was asking about the ECM ... SQUIRREL!!!

Note: Early 2008-2009 CTS also had a optional 3.6L MPFI LY7 engine (multi-port FI) non-DI 3.6L

these engines (LY7) use the Bosch E77

I have one of these... no tuning support yet. EFI Live can read and write, but no mapping support.

Hoping I don't have to map the bin file myself...

We support this engine type in Asia and Europe, when we attempted to manually simulate the ECU type for North America the hardware ID are different than the overseas models. If we had a local vehicle in Phoenix, AZ or had an ECU physically in house to directly flash via BDM we could then determine the coding for the North American vehicles and support this via IPF Tuning. So if any volunteers want to send us there ECU or vehicle we could make this happen.
