Torque Management?
Torque Management? I wanted to know if torque management actually slows you down? I want to know do i really need to have it deleted and what effects will it have if i do not have it deleted. Thanks in advance.

Well from what i heard before and after my TC install it makes a slight difference some people say like .05 of a second and it comes into play between shifts i left it alone for the time being and every thing is fine
this is what i heard not what i know but every thing is running great on my car hope this helps

it does what blackWS602 said. the reason it does it is to save the tranny from taking a punding everytime it shifts. people tend to start having tranny problems after it's been deleted for a while so unless you have the money for a rebuild(just incase)i wouldnt suggest messing with it.
If your having issues with it...
Yes, absolutely it slows you down. If your having TM issues, get tuning! Have it removed. I tried everything to work around it... it's not worth it, bite the bullet and get tuning.
If your not having issues with it and have no other reason to get tuning, then leave it alone.

Verdad Gallardo Thanks for the replies. I do have some more questions though. If it does start to give me trouble what exactly is going to start happening so that way i know that ......that is the problem. Also i do notice that at WOT my shifts arent really hard and i have a TCI shift kit. Normal driving the shifts are really really hard. If i delete it will the shifts be a lot harder at WOT? Is that what you guys mean when you say the shifts are a lot better after deleting TM? Thanks

I know my car almost nose dives everytime it shifts. I have heard that its torque management but I have also been told that the high *** line pressures of the FLP transmission can cause it too.

I removed the Predator tune today to go get the car serviced
(just for luck). Driving home I got on it more than half throttle
and on the upshift it actually pulled me forward, it "managed"
so well. Never felt this on the stock converter but the 3000
stall TCI makes it really noticeable - and I never felt it after the
TC install because the Predator tune was in there before & after.
Yechhh.

i think i have a problem with my tranny but maybe its TM related... when im crusin on the highway around 60MPH and then floor it to WOT it downshifts to 2nd and the RPMs go up and everythin seems ok and then when it shifts to 3rd the rpms come down and stay there for about a second or 2 and the car wont pull ...the rpm's stay still...and then after the quick 2 seconds it pulls again and the rpm's go up.. this only happends from a 60-65MPH roll, is this TM or somethin else? thanks for any help
Torque management should come and go in a couple
tenths of a second. Maybe it seems like two seconds.
It is matched to the duration of the shift cycle and
goes away once in the new gear.
If your mixture is way bent ("no tuning"?) and you are
depending on the closing of the loop to get your mixture
back right, this has a lag like you describe.
Bad knock retard also has a long, persistent "tail" that
takes over a second to go away once triggered. Upshift
is where the last traces of KR lurk when you're almost
tuned right. If you're mis-tuned lean, you might have
some big retard values that take time to go away.
Only logging (or at least real-time event viewing) can
tell you what's up with that.

I haven't seen any KR lately. I was seeing some major KR a few months back but I haven't seen any lately...... well other than maybe .5-1.8 degrees in the top of 3rd gear which has only happened a couple of times.

I have a 2001 Z28, and had a Y3000, 2.0 STR TC installed about 2 weeks ago. I have about 150 miles on the vehicle, and I am experiencing TM issues.
The problem seems to arise at more aggressive launches from a dead stop. Going close to 1/2 trottle, the vehicle "floats" between the first to second shift, and through the rest of the gears, I get alot of "RPM" hunting. When driving the car "normally" I do not experience this, and the car is FAR more responsive. I will have my car dyno tuned in the middle of this month, and I am sure that manipulating the TM settings will solve my problems at more aggressive throttle.
TM WILL DEFINETLY SLOW YOU DOWN.

mine could have also been caused because the band was brand new and was sticking to well?
TM pulls timing -way- back during shifts. But it goes away quick
according to my logs and others I've seen. Like -5 degrees spark
advance, but only for two 1/10 second record ticks and then
back up into the +20s.
Now, if your trans is shifting slowwlllyyyy like stock is programmed,
maybe you get a lonnggg TM dwell along with that? But 2 seconds
is a bugger long time for shifting, even stock. Anyway, if you have
something that's hanging up your shift adaptation cycle time you
might be seeing TM all the while.
Log it. If your spark timing is still above 15-20 degrees then you are
not seeing TM. TM squashes it flat.
