2013 Scion FRS – Kraftwerks
Category : Automobile Performance
On Saturday got a chance to calibrate another Scion FRS that was forced induced. This vehicle had previously visited our shop on the later part of December to get a baseline done. On that given day which the ambient conditions were in the 66F with 65% humidity.
The owner had just fitted the vehicle with a Kraftwerks supercharger set up.
No other mods were present besides the supercharger kit on this vehicle with a Automatic transmission.
On that given day the best number that came out was 214whp (with the Kraftwerks ROM) and it was tested in sports mode in 4th gear.
Fast forward to Sept. 16th with ambient conditions in the 97F, 52% & 30.10 baro, so a rather humid miserable day and the best that the vehicle managed to baseline line was 189whp @ 12psi. Now that we got our baseline we plugged the EcuTek Protuning kit and proceeded to start from scratch with our own calibration to improve the performance from that Kraftwerks ROM file the car was using.
Needless to say that with movements in Fueling, timing advance and cam timing we managed to improve from the numbers on the tuning day and also surpass the numbers from the colder December day back in 2016. Very happy with the numbers and can not wait to calibrate this car once again when the owner starts adding UEL header and exhaust components to free up some low end torque.
