    What ECM does a 2010 Cadillac CTS with the 3.6 V6 Direct Injection use ?

    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.


    Thanks

    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.

    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
    Also: starting in 2012 both the 3.0L (LFW) and the 3.6L (LFX) use the E39 controller

    Re: What ECM does a 2010 Cadillac CTS with the 3.6 V6 Direct Injection use ?

    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?

    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...t-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.

    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.

    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
