    Okay I'm needing someone to do a detail writeup on how to dyno our Jeeps on a 2WD dyno I'm sure its not that difficult I'm assuming pulling the ABS fuse and disabling the tfer case??? but a good writeup would be beneficial for those of us that have zero access to an AWD dyno, thanks

    Step 1: Pull the jeep onto the dyno and strap it down

    Step 2: If you are running a stock tune/pcm*, you will need to pull the ediff and abs fuses under the hood as shown below.

    *If you have a Diablo Predator handheld, go to the options and disable ESP.

    Step 3: Crawl underneath your jeep and unplug the transfer case plug located directly under the drivers seat.

    Step 4: Start the jeep and immediately put it in autostick and accelerate quickly to 4th gear or else the jeep will go into limp mode and will not shift out of first gear. (If this happens you will need to turn off the jeep and try again)

    Step 5: Once you are in 4th gear autostick you are ready to dyno. Have fun and be safe!

    Step 6: Dont forget to reinstall fuses/turn on ESP when you are finished dynoing your jeep.

    I went on the Dyno a few times already but never pulled the Ediff fuse, just the ABS one and unplugged the transfer case.
    Is pulling the Ediff fuse an extra safety ?
