Hey guys, first post here. Own an Altima, figured I would ask this question on the Z forums because of the knowledge base with Osiris and Uprev that the Z guys have since it is more widely used.

My question, Is there any way that you guys know of to up the TCM shift points with Osiris? My rev limiter is set to 7300(yes I have JWT cams & springs so no worries there), but it is kind of annoying that the car still shifts at the normal 6750ish rpm and not at 7250ish unless I hold the shifter in the down position and run it out that way. Am I SOL or is there a way to do it that you know of?

Thanks
Aaron

valid question... i was under the impression those parameters could be altered.

maybe someone knows for a fact...

What do you mean "hold the shifter in the down position and run it out?" You mean you just wait longer to shift in Manual Mode?

Yes, hold the shifter in tip tronic mode to the - symbol, and it wont shift up until you let off of it. Same thing if you are cruising in 3rd gear at say 30mph, and you hold it in the + position and completely stop, it will stay in 3rd gear when you take off again.

This was Jared's response from Uprev

Unfortunately no, we do not have a way to modify the AT computer which controls the shift points. It's a TOTALLY different computer inside the valve body. There aren't any plans in the works to add support for the AT computer anytime soon.

Sorry,

Gonna have to try out the holding it at + or - sometime.

Yeah holding it down in - works, it takes skill to let off at the right point to get it to not hit the rev limiter before it shifts, but I got it down decently. Only problem still is that even when I do that, it pulls timing where it should normally shift, then bumps it back up when it realizes its still in the same gear and I can't figure out a way to tune it so it doesn't do that. Its going from 34-35 degrees advanced to 4-8 advanced where it would normally shift, then back up to 29-30 after it sees its still in the same gear.
