I have tried repeatably to adjust features like rev-limiter and idle rpm lowering and have had no success. I want to raise the rev-limiter to around 6150-6200 and lower the idle rpm's to around 500 and it does not take either. The rev-limiter still hits at 5700 and the idle still stays around 7200, I was adding a 2% addition of fuel to also to see if I could gain a little HP but can't see any difference their either. I also noticed it will not reset the TCM adaption now either, it worked before with previous firmware. I will attach my info file as well as last tune wrote for your assistance. Hopefully we can utilize the options you claim to be able to adjust! I want to be able to tweak this to my liking as mods come in for this. Thanks for any help you can provide!

Auto trans?

Yes with STP option

this should fix the rev limiter

Thanks Mike, will there be a fix for the rpm setting soon?

lowering the idle is not always something the pcm will allow...

Mike,

Noticed a couple of issues and found a solution to a couple of write failures today. When experimenting with different tunes today, I experianced several errors during writing of new tune and recoveryof original backup. I tried several differant methods before pinning it down to the shift firmness, if you cycle key like it states while installing or recovering, the write process fails and vehicle goes dead and does not power up on key turn. When selecting this optionand ignoring key cycle for either install or recovery, it does not fail in either mode! Note, I still have not found a method to reset TCM Adaption. Hope this helps you for a future upgrade, I'd like to see some other options become successful as well!

i had my 2011 Charger tuned today with a custom tune off the can tune 91 oct, and i too had write errors/failure when i tried increasing shift firmness. other then that, car tuned well once i didnt include a shift/transmission change to the tune. hoped for a little more power/torque but im not complaining. Glad i got it tuned with the DCX...and i LOVE the throttle booster!! finally dont have that "lag" when pushin the pedal!

thanks Diablo!

Same thing happened to me when I tried to download the shift firmness to the 93 tune, I kept getting errors. It was fine when I added the throttle boost & changed the tire size. I still wish I could increase the shift firmness. I also tried to update the firmness after the 93 tune had been installed.
