After a long wait I finally received my tune files back from Overkill for my 2010 3.5. I loaded up the 87 tune and trans tune last night and must say this is a completely different feeling to the car. the trans funky shifting i had from 1-2 is gone finally, but i noticed this thing is all too happy to drop out of overdrive. which leaves me to question a couple of things. does anyone know if i can do any tuning to the trans program with the tuner Overkill sells? i know in hind sight i probably should have purchased the hptuner to perform this function, i can't justify the extra expense at this time.

also is there a limit to the number of times you can flash an ecm or tcm? i performed the tune steps last night with the ignition off then doubted it worked so i did it again with the ignition on (car not running) to make sure it was done properly. the thought also came to mind if i start getting funky shifts again i can always just re-flash the tcm program only to resolve the issue.

the tune i received for the higher octane says 93 octane i believe. i don't remember off the top of my head if this is an octane i cane obtain easily and would i be safe running 91 or 92(i think 92 is more common in the stations i frequent)? i don't figure a 1 octane difference would matter much but just wanted to be sure before doing so. i do generally stay with top tier stations 95% of the time but occasionally vary to whatever i can find during road trips.

another point i noticed during the programing is the handheld flashed error a couple of times during the process when i pressed buttons it wasn't expecting? anyone else seen this before? also it kept asking if i wanted to license this car (terminology might be a bit off but that's the gist of what i thought it was asking). does it ask that every time or only on the first time or two using the handheld? there aren't a certain number of flashes available for this tuner are they, then i have to buy more "tokens"?

just a couple of questions, thanks for any input anyone can offer up.

Thanks for the info. also i went back and looked and it appears he's selling the HPTuners himself now (recommending them on the site). however that option isn't listed for the 3.5's so i'm unsure if i a person could use the HPTuner on a 3.5 or not (i don't see why it wouldn't work), I'm just thinking out loud at this point.

after travelling to Michigan this past weekend i started looking more closely and found 93 octane at every gas station we visited. so the 93 octane question may be a non-issue.

Thanks for the input!

i took a quick look into the autocal program to see if i could tweak things with the programming itself and backed off after looking around a little bit. i'm unfamiliar with the program and afraid of screwing up my good thing i have going (and i'm in IT lol). so i suppose at this time i might keep looking into it but don't have high hopes at this time. after driving it in the rain i did notice throttle control was a significant aspect to driving i haven't had to do previously with this car. starting to think i may need to swap back to stock for the winter months to avoid burning through tires quicker than normal due to slick conditions.

yeah at this point after a week of city driving it's already starting to "re-learn" that funky 1-2 shift, and a 3-4 shift it didn't use to have before. seems to occur about 2500-4k i suppose, like it's expecting you to keep into the gas harder but it needed to shift sooner than anticipated. i thought about just re-applying the trans tune again to get rid of it. at this point i'm not ready to spend anymore on another tune controller but i may change my mind after summer. i still need to buy those spyder headlights at some point as well. just blew another sylvania bulb, thought about trying phillips this time.

Try a set of Hella high performance bulbs. They are much brighter than the Sylvania bulbs and will last much longer. I've had my current set (all four bulbs) for about four years now with no issues.
Thanks for the suggestion. I wound up going with a set of spider ccfl halos and think ill leave them as they came from the factory
