Torque Management and Nitro ECM

1828 Views 9 Replies 4 Participants Last post by  KenCary
Can someone explain exactly what "torque management" is as it applies to the ECM? Is this strictly a feature of Nitros with automatic transmisssions?

I have been told that torque management is more or less defueling between shifts to control the torque and power to be gentle on a stock tranny.

It does not feel like my 6-speed Nitro backs off any power when I put in the clutch.

This is likely a question for NitroTech.

You want he super-nuts-thorough answer read here:

The short answer is the ECU takes the input you give the throttle in the electronic throttle system, reads that input, determines if there is wheelspin or some other factor that would necessitate less throttle and adjusts the value accordingly for the most power dilevered without wasting gas and keeping compliant with emissions.

That being said you can still spin the tires and whatnot, but in a car with TM turned off it's MUCH easier. TM can be used with manual transmission cars as well.

My Mustang HAD TM from the factory... Not anymore. With programming changes you can change how aggressive or non-aggresive the torque management is or you can eliminate it altogether to where the electronic throttle reads the pedal input and gives theat exacct amount of throttle without adjusting it.
Calling Nitro tech.

Other than in the case of ESP engagement or during roll-over mitigation, is there torque managment on my 6-speed Nitro?
In stock trim in 1st and 2nd gears it WILL NOT give full throttle. It limits throttle to 85% in 1st; 90% in 2nd.

Before I went with the supercharger I added a tune and an intake. 30 HP.
To what car are you referring and with what transmission in this post?
Torque Management uses a selective fuel shut off to achieve a 50% reduction in engine output torque and a 30% reduction in energy dissipation during shifts. Shifts are very smooth because the electronic control senses input and output speed changes as shifts occur and adjusts hydraulic pressure accordingly. Adaptive electronic control provides up shifts and down shifts with a smoothness unattainable with strictly hydraulic transmissions.

No. However, the PCM will control the ETC during shifts. It typically commands the ETC to hold or slightly increase RPM during shifts. :smileup:
Thank you that makes me feel better.

Now that you mention the PCM holding or increasing the RPM during shifts, that explains why sometimes my shift into first is not as smooth as I would like. It somethimes feels that I am getting more gas than my foot is telling the Nitro to give.

I guess they programmed it to avoid stalling for inexeperieneced drivers.
