Help with shift points and TM Starting to do some tuning for the first time and need some advise on shift point settings and TM adjustment/deletion. Atap showing as much as -8* of timing being pulled out on occasion between 1-2 WOT shifts. Should we delete TM altogether or just "reduce" it. I also need some baseline settings for shift points with this converter, both part and wide open throttle. My friend is by no means new to Atap or LS1 Edit (I however am), but he has a 6 speed car. Any help with with the above items would be great.
And for the record, I have a TCI 4400 converter and a TCI shift kit. Motor is stock with just LT`s and the usual. Also stock 3.23`s. Thanks.

Re: Help with shift points and TM TTT for you. I would also like to know about the Torque Management removal/reduction. I have been told that you should just reduce it by like 50%, but have only found where people have completely removed it. I haven't done any changes to mine yet, because I am unsure if I should completely remove it or just reduce. Maybe somebody can give us both some input.

Re: Help with shift points and TM Well, I don`t have much to compare it to other than the stock converter. That said it really is not that bad as far as being too loose. I don`t have any track times as of yet with this set up. I`m trying (with no luck so far) to get the tuning sorted out. I don`t plan on changing gears until I kill this rear end but I`m sure it (the `verter) would love a set of 3.73`s or 4.11`s. As for as the SOTP feeling, this thing pulls like a monster! She seems to get a little warm on long trips but I guess that`s part of the game.

As for the shift points you will have to do some plug & play as each verter will act differently. I just put in a ViG3200 and I was hittin the rev limiter so I left the WOT RPM change alone and reduced my MPH change from 1-2 & 2-3 by a couple MPH and my problem went away.... but like I said each verter will act differently Trending Topics

Re: Help with shift points and TM I've been playing with the MPH shiftpoints
using the Predator. I figure there's probably
the same kind of thing in Edit. Anyway, I have
been incrementally raising them and seeing an
improvement in how the car behaves at mid-
and higher-throttle, especially around town.
I currently have my 1-2 at 60MPH and the 2-3
at 110 MPH. These are well above the factory
settings (which if I recall were something like
40 and 70, short of the speed-in-gear at 6000RPM).
Pushing the MPH values higher is making the car
downshift more like I want it to, instead of
lugging at mid-throttle. At my current settings
the light-throttle shifts are still soft and low
but I stay in lower gear a fair bit longer in
mixed driving. WOT shifting is RPM based.
I think I'm getting close to where the staying-
in-gear might become annoying, but haven't found
the upper threshold quite yet.
One thing I'd like to know from Edit people -
the Predator sets an upper adjustment limit on
all MPH shiftpoints at 125MPH. This is a don't-
care for 1-2 and 2-3 (though 2-3 is getting close)
but I'd really like to push up the 3-4 to above
the RPM-based shiftpoint as well, and this would
want at least 135MPH. What does Edit let you do?
Is 125MPH a GM limit or a Predator limit?
