Traction Control Specific Signals shown in the right margin of the
Driveshaft Replay window
1. DS Error = Driveshaft Error – Shows the difference between the TOSS_rpm and the TISS_rpm.
Values will be displayed in positive and negative numbers. Negative numbers indicated that the
previously defined curve (the TISS curve) exceeded the Des TOSS curve.
2. TOSS_rpm = Driveshaft Speed – Shows the actual driveshaft speed recorded.
3. TISS_rpm – Shows the interpolated curve resulting from the previously entered values into the
Desired Driveshaft Curve.
4. DES TOSS – Desired Driveshaft Speed = Shows the desired driveshaft curve as it is created. As
values are entered into the Desired Driveshaft Table, the DES TOSS curve will appear in the Replay
graph. WHEN MAKING INDIVIDUAL CELL ADJUSTMENTS, THE “ENTER” KEY MUST BE
PRESSED FOR THE CHANGES TO STAY! The Desired Driveshaft Curve should be 100- 200
RPM above the actual driveshaft curve from the Replay you selected.
5. TMR Enable – Timer Enable – Shows when the Timer Enable sequence started (when 12V was
applied to the Timer Enable wire, Hdr 1, L2).
6. TorqRetard – Torque Retard Value – Shows the timing retard value the GEN3 ECU applied for a
given Driveshaft Error RPM to control driveshaft speed.
