Here are some points for driving and maintaining an SST equipped vehicle.
-When possible idle car in neutral. Examples: long lights, drive-thrus, traffic jams, long stops, etc.
(Reduces clutch wear by reducing pressure when idling).
-Do not launch car when transmission temperature is below 70C.
(Launching places extreme loading on the clutches and when transmission is not up to ideal operating temperature it will cause slip and more wear).
-Do not WOT the car if transmission below 60C.
(Same logic as launching a cold transmission).
-Do not over cool transmission. *A sump and aftermarket cooler while maintaining the OEM SST thermostat is the best option.*
(Over cooling can reduce ideal operating temperature causing clutch wear. The clutch pack operates within an ideal operating temperature range. The OEM SST thermostat for the cooler is set at 75C).
-Let the SST cool down when necessary. (Do not just shut the car down).
If the car has been driven hard for a long period of time (ex: road course racing), the SST temp will be high, as will oil and coolant temps. Some normal driving to keep fluid moving through the cooler with airflow will bring temps down safely.
-Do not WOT in Normal or Sport.
(Normal and Sport mode allow more slip than S-sport and will cause wear on the clutches).
-Allow transmission to warm up in Normal or Sport mode.
(The slip from Normal and Sport mode will allow the SST to warm up faster and will have less ‘shock’ on the drive train with cold fluid).
-Do not run aftermarket fluid.
(Aftermarket fluid has been shown to cause the clutch pack to wear prematurely).
-Change the fluid and filter at 10k miles if car is tracked and 20k-25k miles service intervals if car is a daily driver.
(Replacing the fluid is cheap insurance against having any severe clutch or transmission damage. We do recommend doing the transfer case and rear differential fluid at the same time).
-Occasionally perform a teach-in.
(This will put the SST through a relearn procedure. This will help reduce potential slip and help the SST last longer).
-If engine exceeds OEM torque, adjust ECU so TCU knows.
(Adjustments must be made so the TCU is aware that the transmission is making more torque than stock, otherwise it will slip the clutches too much during shifts.)
-Intake changes (beyond a drop-in filter) require a tune.
(The SST relies heavily on the MAF to calculate torque. By changing the intake the MAF reads different than the MAF scales, which can affect the SST).
-Do not let off the throttle between shifts.
(The SST uses lots of information to determine what it should be doing. When accelerating, the SST has the upshift gear selected and vise versa for decelerating. Lifting of the throttle also decreases clutch pressure. So by letting off the throttle during the shift, the SST will get confused. This can cause a delayed shift and slip).
-Do not tow anything.
(This is beyond the design of the SST).
-Consider using Normal for freeway cruise.
(SST Normal mode, the SST will just leave inactive odd gear train in neutral to save fuel and reduce noise. Even if you go on-off-on-off with the acc pedal, the inactive gear stays in neutral. Compared to cruising in 6th gear (Manual) S-Sport, SST will toggle the inactive gear between neutral and 5th every time you apply-lift the accelerator).
-Driving in S-Sport will save your clutches, do not drive in Normal as often as possible.
(S-sport has up to 20% more clutch pressure than Sport mode, even more than Normal mode. This reduces slip, heat, and wear).
-Get the NRG Ops Custom Firmware. (https://www.nrgops.com/product/remote-sst-passthru-can/)
(Our custom firmware allows you to select S-Sport without holding the switch and while moving, removes rev hunt on the Ralliart, and we can adjust things like global clutch pressure).
