PSA for anyone running a Whipple or Roush Coyote

[engineermike]

I inadvertently discovered that Traction Control can lean the lambda out to cut torque. This is not the same thing as Fuel Cut, and my Fuel Cut Torque Ratio (ECM 44775) is already set to 0.0 for Traction Control (stock is 1.0). I believe you can set the lean limit for enleanment torque reduction in table ECM 44170 as a function of engine load and speed. The Roush and Whipple calibrations do not modify this table so it appears to be able to lean it to 1.1 lambda for torque reduction. However, the GT500 table limits the enleanment to 0.75 lambda at loads above 1.5, which makes total sense. I made this change in my cal but I haven't tested it, and don't really plan to unless I forget Traction Control on again....
