Has anyone been able to crack the tuning codes for the Aisin equipped Rams without any issues? I've heard both yes and no, but nothing definitive. I don't want a super high power tune. I want something more along the lines of optimized power/torque management, be able to do the emission deletes with no codes, and have it play nice with the tranny. I find it hard to believe that as long as this tranny combo has been out and available, nobody has figured out how to tune it...what's the deal??? Raceme told us that I could go with a small tow/economy tune and not hurt the tranny, but anything more could limp the tranny and really hurt it. I guess without upping the line pressures among other things, the Aisin will be all sorts of ****** off. Can anyone in the know shed some insight into this for us Aisin owners? As a side note, my buddy who has a tuning shop here in Kansas City told me that there are no Aisin tuning codes available yet through EFI Live, and SCT hasn't touched it either....***!? I'd really hate to damage such an expensive tranny in an effort to increase MPG and power.

Did you seriously just reply to a nine-year old thread??

[QUOTE=SOhappy;3315961]Did you seriously just reply to a nine-year old thread? Guess so. I typically don't look at the date on a thread to see if it's "expired" like a gallon of milk. For what it's worth, I don't think the Aisin tranny has been available in the Ram for very many years...at least not in this country anyhow....so why would I even question how old the thread was.

Well, I guess you did provide us a historical perspective of the Aisin...
