Default torque management with nitrous

Recently at the track i had some issues with the window switch and stall converter. The converter flashes an extra 200 rpm on the nitrous ( or the stock trans slips?... lol) and when nitrous shuts off it falls below the window and reactivates, in the logs it looks just like im hitting the rev limiter but its the nitrous turning on off on off and finally shifting. I know its not the limiter because because its set at 6600 and window set at 6300 (which is where this is happening).. Anyways an idea popped into my head to use torque management and just use the window switch to shut off before rev limiter and turn it on when i want and then use torque management between shifts to limit the power and just keeping nitrous activated. I dont want the extra power through the shifts but dont want to deal with the window switch for shifts either as torque management could be more precise.. torque management just limits timing so no real risks correct? Thoughts?

my thoughts are take the window switch and sell it i havent run one ever just for that simple fact i spray through the shifts with a 4k converter and stock trans with a shift kit and its still fine even on both stages. just pick up a wot switch and an on off switch and youll be good

oh and the converter will flair more on spray because the amount of power the engine is making is greater i see a 2-300 rpm diffrence on the juice then on motor

As said the conveter should flash higher on the spray. General rule of thumb I have always heard was 500 rpm. Obviously the exact number is differant for every converter and set up.

The simplest way to look a converter stall speed is Power in VS. Resistance out. The more HP ORthe more resistance to move the vehical(weight or gearing) and it will stall higher. Obviously the juice increases HP noticably.

Do not do this. First off you can spray through the shift with a window switch. It's as simple as setting the rpm after the shift and before the limiter. You can have the exact same performance safely. Do not take off your window switch.

If you would like you can e-mail me your logs if they are hptuners. I'll gladly help you get the car lined out.

no definately not getting rid of the window switch.... Setting the window switch to spray through the shift and shut off before the limiter is exactly what i planned now, but to use TM to soften the power to the shift under spray... just making sure it is safe, and since it only reduces timing i see no reason why it wouldnt be...? I do have hp tuner logs..


To the other guys... I know the converter flashes higher under more power, thats why i am having the issues with the switch. When the nitrous kicks off the converter falls 200-300 rpms then the nitrous kicks back on. I know the problem, just wanted to make sure my solution was safe because i do not want to spray through the shift..

Taking advice from this Camarokid idiot will cause you to be picking up motor pieces.

im spraying through the shifts on a 150 shot and a stock trans... it loves it. shift point it set at 6200 rpm. rev limiter is 6400 and nitrous set to turn off at 6300. it has worked great. i figure its worse on the trans having the nitrous turn on and off like that vs just going through the shifts as normal...

your car is alot lighter which helps with logevity. mine is heavyyyy lol. actualy when it does this it stays in limbo doesnt shift and only picks up 3mph over nearly 7 tenths of a second. so its slowing me down. ive got a flt L4 coming so im just gonna let it eat and see what itll do i guess.

gonna activate the TM to 50% in the mean time.. see im pioneering a new type of drag racing. see how close i can get to 7..35 with the highest trap speed... lol goal is to not get kicked off for no roll bar. 5 point belt, or fire jacket. blah blah blah. pretty funny to launch so easy with m/t and mash it 30' out. was beating up on a procharged mach 1 last week doing this. 588 hp sticker on the hood with supposedly 490ish rwhp..?all while clicking off 8.2's at 92... lol

Throw a progressive controller on it if you want to manage the torque. I'd be uncomfortable trying to use the stock torque management in any sort of a performance situation.

Why dont you just pull the timing from the actual timing tables when your at the track?

I actually used tq managment with my c5. I sprayed a 300 directport. The way I set up my progressive was 100 out of the hole and full ramp 1/2 second. The ran nitrous up to 7000 rpm with 200 rpm for shift. At 7200 it shifted.
I then had my 1-2 shift TQ management set at 15%
Then 2-3 shift was set at 10% . That worked well for me ran 9.5 at 149 but multiple 9.6 passes like 60-70 on built 4l60e

I don't have my Hptuners here on the work computer, but im 95% sure that the TM only pull's timing correct? If so why not just pull the timing from the base timing map for the nitrous? Why mess with percent values through TM?

One of the reasons I used tm was so that I had full power till shift. Made it easier on the trans to take 300 shot. I under stand just pulling timing but I think my TM saved my ttrans a few times.
I tried with and without and if I had any wheel spin trans would not shift. Then set my TM and even if wheel spin occured it would shift. But my first gear came on quick.
4l60 3600 stall 3.73 gears 27 inch MT drag radial.

Right I under stand. But why not simply pull the timing at the shift? Just pull X* of timing 100 rpms before shift.
