AF40 TCM Tuning 2.0T XWD

Description

Aisin AF40-6 Transmission Custom Tune!

Adds Aisin AF40-6 TCM Reading, Flashing, Datalogging and Custom tuning to your existing Saab 9-3 2.0T Autocal V3 handheld system.

The factory automatic transmission limits the allowed torque to 370 Nm (272 lb-ft) in 1st and 2nd gear and 450 Nm (331 lb-ft) in gears 3-6. Brake torque was also limited to ~ 160 lb-ft which prevents building torque while stationary by pressing the accelerator pedal while the brake is applied.  All of these factors severely limited the acceleration performance for the 0-60mph and 1/4 mile times.  Raising these limiters now allows for  aggressive launches at full power with much quicker 60ft, 0-60mph and 1/4 mile times as demonstrated here with my 2009 9-3 2.0T SC XWD at Stage 1: Stage 1 2.0T Dragy video 0-60mph in 5.58 seconds
