okay i've been doing lots of back and forth with eric this week about shifting issues also.. i havent' used XR in months because i did not like having the converter lock up so much because i couldn't spool my large turbo w/out the RPMS...
however after doing MANY different scenarios with the SCT and trial and error this past week and picking erics brain, (not to mention having him write me all new tunes also) i've finally got what i think is a winner...
first off, what size and type of turbo are you running ?? vgt/not?
what size injectors ?
and very important here, do you have any tranny mods at all or aftermarket converter, or is all of that stuff stock ??
whatever you do, and trust me i know it's easy to think you need to up your shift pressures but even w/out changing them, eric has already bumped them up enough with the tune to safeguard your tranny trust me..
anyhow.. try this and tell me what you think.... it may not work for you as well as for me, but i'm running a large NONVVT turbo that lags a lot, BIGAZZ injectors, and a fully built tranny and heavy duty converter...
make sure you have your axle ratio set right (easy)
play with your tire revs/mile also... what size tires are you running ?? i'm running 35" tires (which measure out to 34" w/tape) and that comes to 595 revs/mile.
circumference is: Pi X Diameter. (Pi is 3.14159) so for a 34" tall tire w/a diameter of 34" you get a circumference of 106.81"... this is 8.9'... a mile is 5,280', so divided by 8.9 gives you 593.25 revs/mile... adjust the math to fit your tire size as necessary.
this makes a BIG difference in the quality of your shifting..
second.. DO NOT ALTER THE "WOT SHIFT/MPH" settings at all ! !!! leave them all at ZERO.. eric personally told me this as he writes the tunes to shift at certain RPM now, and something about how they would try to "anticipate" a shift rpm by mph w/the user options or something.. i can find the email if you really want the detailed reason why. but basically DONT change that, let the tune itself control the shifting and i'll tell you what it made a WORLD of difference in the shifting.
as far as shift pressure, like i say you don't NEED to up them if you don't want to and you will be safe. personally i have my 1-2 shift at 10%, and all the other shifts at 5%.
this has been working out well for me but of course feel free to play with it. but just don't mess with the other option i was telling you about.
i actually like the XR tune now, and i think it drives better for daily driving than my XS tune, i have no idea why but it just does !
