So in drive with an auto transmission it will shift at 6k rpms in first and 2nd and even in 3rd if you keep OD on. With an upgraded ecu does this still happen or will it go 6600 redline in drive?

 

you'll most likely have to manually shift, my 2-3 shift is at ~6100

with an extended redline, say 7000, YOU WILL HAVE TO manually shift, or the Transmission Control Module will shift early

that is why having 5-speed is better in THAT respect.

 

No, and there's no point unless you have a VI.

But when and if you do get one or have one... This thread is helpful.

when my car is cold it shifts around 6400rpm but when its warmed up it shifts around 6100 6200rpm

 

Nice to know you bring the engine to those rotations while cold..

 

my auto shifted at almost 6800 rpm ad when i put the jwt in there now its shifting at around 7400 rpms if i don't let up on the gas.

 

Anomaly #1. Anyone else?

 

ive gone to 5.5 - 6 and shifted the auto... 1nce or 2wice... its not worth it for me.. cause i have no mevi or 00vi... i mean i feel like the car isnt really gaining anymore speed.... so .. its sorta useles.s... .. i did it on a empy road at 1am... but if u lett off the gas then ... it shifts.. even if u let off a bit...

 

you guys know the stock rpm gauge is inaccurate at high rpms right? What are you all using to get these redlines from?

My auto shifts at 6100 according to the SAFC
