What info do you guys have on making adjustments on a 4L60E with edit? What kind of adjustments did you make and what mods did you have at the time? I'm looking to get a starting point for mine. I basically just have bolt ons now but other mods are on the way. I'd just like to get an idea what you guys did with your shift firmness and shift points. I have a 3:23 rear so if you have any suggestions I'd like to hear them. I'm taking notes on just about everything I find so I can make a help file for new people to tuning. It's been a pain for me just to get started so I'd like to help out people that come after me.

goto ls1edit.com and load up some of the binaries from there. there's a few modded a4 and copy the settings over to yours.

you got a shift kit? if not, might be a good idea instead of screwing up line pressure

I have been playing mainly with part-throttle shitpoints
and TCC lock/unlock settings (getting the kickdown to
be pedal-proportional instead of resist-and-blast, etc.).
I decreased the adaptation time settings to a uniform
0.100 (get rid of the 0.300 in the midband which give
lazy shifts under moderate power). Have only begun to
mess with the line pressure profile, as I understand things
the TCC pressure is a sub-regulation of PWM line and this
(TCC slip at part throttle) is something I need to kill.
I am working in HPTuners though, not Edit.

Adjusting line pressure profile to have more PWM-line at
lower torques, if you do not change the maximum, should
add no risk. I would only add as much as you need to
prevent clutch slip, if you see no slip then main line does
not need to move. Adaptation time settings are what
produce the firm shifts.
