    Cannot change tire size/gear ratio

    Hey guys,

    Just got my VCM Suites Standard, Plugged it into one of our jeep wrangler jk's.. this one is a 2009. I was looking under speedometer for the tire size/gear ratio.. But have had no luck. Any help finding this feature would be greatly appreciated. I'm not sure if that feature is only available on pro or what the deal is there.

    Thanks

    You do it from the scanner. Connect to the car and hit the green button.

    For 01 C5 do you also change from scanner with 3.0? The editor use to have tire diameter option, but now its only tranny revolution/mile... which I can't seem to get the calcs correct.
    I want to change my tire diameter for an accurate speedo.

    I've looked everywhere and I can't find tire size/gear ratio anywhere. I have tried the above suggestions as well. I click on the gear/tire Wizard, but I get Scale multiplier for manual trans table adjustment.

    Update your version first. You are about 40+ revisions behind. If that doesn't fix it, then contact support so they can address it.
