Auto Guys. Got Torque Management Issues?
Guest
Posts: n/a
I've done some research into how Ford programs the ECM. The ECM should be in open loop until the coolant temp reaches 173 degrees.
If you have a tuner that does data logging monitor the coolant temp and try to lay down a patch of rubber with the coolant temp between 160 to 165 degrees. At this temp the ECM should be in open loop and torque management should be off.
Now try laying down a patch of rubber with the coolant temp above 180 degrees. The ECM will be in closed loop. If you notice a significant loss of power the torque management may be the problem. If it is we will need to address this issue with the tuner companies.

George I believed that was my power problem from the start but as you well know I know nothing about computer control. I ask almost every one I network with if they have a clue how to bypass it and no luck to date. I have looked at the real time data and could not see where the timing was retarded however I do not know what the advance should be at a given RPM or where to locate that info. I do have the shop manuals. A while back I asked DS to put the function in the Predator.

You have a basic principle down but not the entire theory. Yes, there is a Torque reduction value on these cars and I don't know using the Diablo but using the SCT tuning software you can either disable it or raise the value's at which it acts. BUT, also on these cars you have the new Drive-By-Wire throttle systems that are also Torque based completely so by disabling Torque reduction you MAY help the shifting but you wont entirely get rid of things like throttle lag and such. You must go into the Electronic Throttle controll settings and work with these values.
I've datalogged a number of cars and some guys with manuals liked it better with Torque reduction on where as the auto guys liked it better with it off? The most important thing to remember is to go with a dealer who'll work with you about it. I can email tunes to my customer who have concerns or questions about their tuning or just want to try new things.
Just let me know if I can help with any questions about it here...
Thanks, Doug.
