i'm getting a retune soon. my question is: should i leave torque management on or off?

don't forget to elaborate about why you vote one way or the other...

Still got the M62? Id say turn it off. Arkansas' full of hills you know

Turn it off so it doesnt limit your boost

Edubs

Everything in moderation. Torque management should be tuned to the application just like everything else...

Brenticus

iTrader: (2)

so torque management just limits your boost? is that in 1st gear only or throughout the gears?

Edubs

Depends on year. On 04-06, HPT has tables for 1st gear and 2nd gear, but whatever you set 2nd at is applied to 3-5. I'm not 100% positive, but I think the 07 LSJ's have a table for every gear...

the reason i ask is for when ottp retunes my pcm here in a couple of weeks, because it has the option to remove it. zzap has the option to give a 50% boost reduction in first gear which sounds like a decent option for take off, but in all of the other gears i'd want full hp potential. just leave it to me and the pedal after that. i mean i can launch okay and i'm a good driver, but launch on these cars is simply not fun for me like it is others and i'd like to prevent wear on my axles and downpipe.

Edubs

You can ramp it up too. The adjustment is from 4000RPM+ every 250RPM. I've seen different tuners do it different ways, but usually they either start at 50 and ramp up or run 50 across the board.

Like I said, it should be tuned just like anything else. If you're having someone custom tune, ask them to start at 50 and ramp up and if you don't burn the tires off, ask them to try again with a little more and keep bumping it up till you lose traction...then back it down a little and you should be all set and tuned to what your susp/tires can handle...

thanks edubs. i'd really like to learn more about tuning. it sounds like something i could get into. the only real reason i haven't bought hpt is because i didn't want to spend $500 while going into the inner workings of our cars blindly, you know.

Remove TQ MGMT for everything but 1st gear. There are two reasons for this:

1. At full boost in 1st gear all you will do is spin anyways. On my LSJ I had 1st gear boost set to 66% in the higher RPM range. On my LNF, I have 1st gear boost set to 60% at 4000 RPM+.

2. The F35/MU3 transmission is rated at 260 TQ (at least technically. GM has the LNF Stage 1 go up to 320 TQ so it obviously good up to that as well) BUT it is only rated to 200 TQ in first gear. Now, I do not know why it is rated lower in first gear or if that applies to both LSD and non-LSD transmissions, but that is another good reason to keep at least some TQ MGMT for 1st gear.

You don't have to buy HPT to start learning mah man. I've posted like maybe a dozen times on that forum but I've spent 100's of hours reading and I would still consider myself a novice, at best.

Tuning takes two things:

1) Knowledge
2) ***** to apply said knowledge

Everything after that is just guesswork...

When I had the M62 still on my car, I was running a vendor's tune that had a ramp-up for first:

4000 @ 50
4250-4500 @ 55
4750-5000-5250-5500 @ 66
5750-6000-6250 @ 88
6500+ @ 200

Haha! Thanks. I'll keep that in mind.

I've heard of people having nice pulls, even in fourth, with it turned off. I personally leave it on right now cause I'm an idiot and I'd do stupid **** to my car.

i talked to josh yesterday and he said that he has it on his car and hasn't seen any issues. basically if you're smart and don't abuse it, it's a good option. personally i don't like the idea of having torque that's restricted by the pcm.

Edubs

Your intermediate shaft begs to differ...

Brenticus

iTrader: (2)

care to elaborate?

Edubs

Torque management is there to help protect your drivetrain. I was picking on the intermediate shaft, but all of the components take a beating when you remove torque management (especially/more importantly in first gear).

Those who remove torque management at higher HP/TQ levels typically are knowledgeable enough to know how to drive the car in that situation and not abuse it.

Personally, I prefer to set a safety in the PCM and know I can beat on it. Again, it's about properly tuning your setup...

I'll let you know what the 07 tables are once my laptop battery charges.

07 is the same as 05-06. boost limit % tables are 1st and 2nd only.

chris88z24

Right. You can't floor it suddenly and slam the motor around in the mounts or else something is going to break.

The WOT box makes shifting butter smooth on a car with stock mounts, except on that pesky 1-2 shift. You still really need to feather the clutch a little instead of dumping it, especially with TM off.

Every other gear you can bang, though.

well josh at ottp said that they reduce boost in first gear on all of their tunes and that's helpful. i'm a pretty good driver and honestly drive on cruise control more often than not. so basically what i'm after is that if the power is there and i want to use it, i can. but 1st gear is still going to limited and that makes me feel better. basically he said the torque management is just less advanced timing. again, i'm not a tuner but it all sounds good as long as i don't beat on it too hard.

TQ management is not boost limiting.

As mentioned, if you know how to treat the car, torque management is pointless. Seeing as most people here don't, that's why they leave it on unless asked. I'd run boost management in 1st if you don't have good tires, you can always run the boost bypass mod to eliminate the ramp in when you do use better tires, that's the simple method I used to adjust for my real tires or street tires. 40-100% in first in the PCM, but on real tires it just slowed me down, so I bypassed the actuator controller.

delete it. and drag racing a FWD is always going to break things its very abusive on the car. my count is 2 axles, struts, 3 sets of control arm bushings. breaking is racing you gotta pay to play

Edubs

I guess we're talking about two different things then.

I'm talking about the boost reduction feature within torque management that allows you to adjust maximum boost pressure at certain RPM's. This simply controls when the bypass solenoid opens to cap boost. On 04-06 models, this can be controlled for 1st and 2nd-5th gears. Most people limit boost in first and I can't think of anyone that would reduce boost in 2-5th. Like I said earlier, if 07+ have the capability to adjust second gear separately from the higher gears, a quick ramp up might be beneficial to those w/ higher power levels, but not necessary. Regardless, this is a WOT thing, not a cruising thing...

bottom line: is this any more harsh on the car than any other power-adding upgrade with similar gains?

Edubs

If you're having it retuned by OTTP and they're going to use some sort of TQ MGT in first, then you'll be fine...
