    We have 1 in stock, but it's not an E67

    2006 4.4L STS-V uses an E67

    This STS is a 2006 with 4.6L N/A, rear wheel drive and I was told depending on which engine, if having boost or front or rear wheel drive had different PCMs but which PCM does the NA 4.6L rear wheel use ?

    Thanks

    This is the E22 ECM used in 2004 to 2006 RWD Northstar's except the 2006 STS-V 4.4L


    This is the P07 PCM used in the 2004 & 2005 FWD Northstar ------ Note it is the same picture -- I will have N0dih update it


    This is the 2 side by side



    ---------- FWD ------------------------------------------------------------- RWD



    This is the E67 used in 2006+ FWD Northstar, the 2006 STS-V, and 2007+ RWD Northstar's

    Damn then not good news as it looks like this STS would be using a E22 PCM since it is rear wheel and not a E67

    That leaves out using Tunercat or LS2edit for tuning, so what tuning tool would work ?

    Thanks

    John says the E22 uses a non AVT supported CPU
