Ranger...please explain: "but my launch is still searching for a technique that eludes invocation of Torque Management routines that pull power on strong launches and "protect' the drive train." Are you saying that the traction, or some other kind, of control is on while you are racing or are you referring to some other function? Please explain.
Also, as long as you are making a guest appearance over here, do you have any recommendations on how to get better times out of a stock Viper?....Bob
The Z06's LS7 motor has a Engine Control Unit (ECU) that measures reading from sensors throughout the engine, brakes, wheels, and drive train, and processes them thru algorithms that control engine, brake and suspension and other functions.
Chevy experienced significant warranty expenses on the C5Z06 due to breakage under hard launch and wheel hop on strong shifts. With the advent of the LS7, Chevy has attempted to mitigate the warranty exposure by causing the ECU to intervene and retard timing and reduce the throttle position (e.g. reduce power to the wheels) when "certain stressful" circumstances are detected. This invocation is termed "Torque Management." It doesn't help the driver in any way; in fact, iIt costs the driver .10-.15 seconds in the 60'. Instead, it helps Chevy reduce part breakage. Principally rear ends and clutches. And in so doing, save them money.
I notice TM activate on DR launches above 3600 rpm and on stock tire launch above 3100 rpm.
I need to work on a launch technique that involves
(1) a lower launch rpm
(2) higher rear tire pressures, and
(3) a more aggressive throttle squeeze.
This is what I mean about "getting the launch dialed-in."
My theory is that if (1), (2) and (3) can be properly optimized, TM thresholds (whatever they may be and the explicit values are not known) may not be violated and TM may remain dormant. If that can be done, then the 60' should recover by that lost .10-.15.
Many drivers are editing the ECU to remove TM. I could do that too. But that would be a deviation from stock. Not my style.
Regarding advice on the Viper, I can't offer any because I've not driven one. But great advice for the RT10 can certainly be had from
Wanted who drove the best passes I've ever seen anyone drive in a near-stock Viper.
