    Disabling SKIM

    I am transplanting a 2004 4.0 Jeep engine, it had the SKIM module installed originally. How can the the presence of the SKIM be turned off?

    I don't know anything about it, But does the SKIM have anything to do with the engine or is in the PCM?

    I thought it was a PCM thing. Might be able to turn it off with a tune.

    So... is 2004 still the straight six or was it the V6 by then?

    And what are you transplanting it into?


    And welcome to the site!

    in 04 I believe the wranglers still had I6 my guess would be thats what he means.

    EDIT: quick search found that TJs were I6 until 07 when they became the JK and earned a max of factory 3.8L
    '98 Grand 5.9 "Black Pearl" totaled
    '98 Grand 5.9 "Eleanoir"

    Thanks everyone for your interest in my project. The 2004 4.0 "6" is going into a 1969 Rambler. Built as a road racer, sleeper, very modified suspension and brakes with a T3-60 turbo. The later versions of the PCM all had the capability to "talk" with the SKIM (module) to enforce secutity with rolling codes. The SKIS (system) was an option, so the PCM had to discover the presence of the SKIM, once detected the security feature was enabled. I don't have the SKIM (module) in the Rambler, yet from the Jeep build sheet I know it was in the donner vechicle, so I need to disable the feature in the PCM. From various tuners (SCT) I have learned sometimes the tuning software can disable SKIM, sometimes not depending on PCM model. So far for my model it is not! Yes, I know the dealer can disable the function, for $$, but I have no running car and they don't make house calls. I can buy a remanfactured PCM which will come with the SKIS disabled, just more $$. Since I need the PCM modified to support the turbo function, I was hoping to be able to disable SKIS at the same time!
