Here is my question and bar with me.I tune my car around 2 years ago.Then two weeks ago I got the new transmission re program done.The car drove a lot better.I have uprev cable so I switch back and fort my self .Well I reflash the car with the old tuning with out making a copy of the new infiniti tuning so .this is my question installing the old tune would give me the old transmission program back on?maybe is a placebo effect ,but to me feel like the old program.is back. there is any way that I can get that program back? I am calling uprev Monday any way.

 

The transmission reprogram also includes a new ROM for the ECU, what you essentially did, was to remove the new ROM, replaced it back with the old.

What you should have done was, have the new ROM cracked by UpRev, and then had the tune MAPs from the OLD ROM transferred to the new ROM.

Unfortunately you now can't dump the new ROM, until you have the dealer reflash you car again.
