picking up a 2.4 auto, need some opinions
#154
I'm indifferent about mickey Thompson or hoosier when it comes to real slicks. but drag radials I picked hoosier because they are basically slicks. They only have like 2 straight lines on the tire lol

what are you auto guys shifting at since you all have tunes lol im seeing 6500 is the stock shift point in HPtuners, i was thinking 6800-7k might be more appropriate

well, did some tuning today with HPtuners, holy god its like a changed car, even in 101 degree heat with intake air temps ranging from 120-155 degrees. Still need to work on fueling and increasing the rev limit and shift speed for 6850 rpm's but torque management is disabled, COT disabled, removed the low octane spark table, and made adjustments to the IAT and ECT spark correction tables, not to mention firmed up those shifts.

im still getting KR on the stock high octane table, dont know what its related to to be honest, and im running 93 octane shell/sunoco gas. As far as I can tell these car's arent able to pick up much more then a degree of timing in the best conditions according to other tuners.

ill be headin to atco probably on friday night to get a baseline and test out the tune to see how much i gain with just the tuner and no mods, ordered a ZZP mid length header and downpipe combo last night, that along with an intake and LSJ throttle body will be the full extent of the mods unless I work up the will to go through with a TVS 1320 setup.

havent purchased the tb or the adapter yet, and i still need my buddy to finish TIG welding up my intake im building. Ill have pics of that when its all said and done. Im trying to figure out how im going to isolate it from engine bay heat ATM. Don't think it will be too difficult with some materials from mcmastercarr though.
We saw a massive improvement in power and acceleration with the tuning we did, the car is just insanely lean in its stock form. Trying to run the high octane fuel map on 93 octane and i was still getting 4 degrees of knock retard and seeing 790-810mv on the o2. We were able to bring it up to between 840-860 and saw a drastic reduction in KR so im hoping with a little more fine tuning throughout the power band at the track we can get another degree of timing stock, and maybe 2 more degree's with the free flowing exhaust and intake setup.

what's your pe ratio set to? Just FYI my car was EXTREMELY sensitive to IAT's. Like 85-90* temps would cause a lot of KR up top with one timing table, then the same table would have absolutely zero knock at IATs of 75* temps.
Suggestion: make your intake a CAI, go into the lower fender area. it will help you immensely.

PE is actually disabled on the stock tune, I believe it is set start at 8000 rpms or something like that. Make sure you have changed that table. If you post up your tune I'll take a look at it when I get home and suggest anything else you should do.
Also from experience: don't mess with VVT until you have got everything else in the tune down. You'll end up changing too many things at once, and the differences will be very slight so it'll just drive you crazy.
