I'd like to be able to turn the TPMS sensors off so it doesn't flip out all the time when I have my drag wheels on. That'd be a nice update alone right there. I haven't done any firmware updates in forever, since I got it last year. I think there was a fan setting update too to have it kick on in the pits with the car off. I'm always nervous of these updates, seems like a lot of times they're not perfect at first. I tried updating my Trinity tuner the other day to get trans tuning for my transmission and all I had was problems. Driver problems, software problems, then finally when I got that all sorted out, the Trinity would try to update to the new crom file and it would just crash about halfway through every time. Then I couldn't even load tunes onto the Trinity anymore because DS Downloader would keep crashing and shut down. Luckily I was smart and kept an old reliable version of DS Downloader and the corresponding drivers on my computer, so I loaded those back on and deleted the new version and now everything is back to normal again. I read on the Hellcat forum that others were having issues updating their tuners for the new crom file as well. Think I'll wait until spring to try that trans tuning stuff out.
