Edit Vcm Tune Changes In Trans Shift Points

[andypower5.7]

:vpo:I just had my clubby a vcm tune two fridays ago on a 33 degree day. When i left the tuner it chirped with slight exceleration with a noticable shift from 1st, to 2nd putting you back into your seat and to this day i have noticed the transmission is not changing like the day it was tuned even flat stick it wont chirp as we have been having much cooler days here in melbourne the last week or so. You guys might think this cant be true but it is as i am a little pissed off why this is happening as it shouldnt. I even noticed when fat stick with power mode on it cuts out and revs out then changes into second but not all the time, it looks like it goes better when its warmer weather then colder weather which should be opposite can someone help me out.

Get Mario to give it the once over.

I will first thing when he opens his new factory on the 15/1/08. Just hopeing it needs a touch up tune just cant think why the wheel chirps are gone very wierd. As i was driving the car last night late and it was about 10 degrees quite cold and should run at its best. Does anyone have marios username on this website or mobile number.

The air density on the tune was 93.7% on the dyno print out at (31c, 1003mbar, 29%) is that high.

This is said by a tuner in the uk.The "backing off" you feel in the trans is torque management. The PCM pulls timing during shifts to smooth out the changes and help the trans last longer. You can remove it and have the car go sideways on the 1-2 shift if you like that sort of thing. Just ask your tuner. As i think thats my problem.
