2013 Scion FRS Turbo – Transmission work & Calibration

Tags : dyno dynamics ecutek frsturbo jdlturbokit scionfrs specclutches

2013 FRS Turbo, rectifying work from another shop on this manual transmission. Seems that synchros went south on this transmission, time to open her up and see what is the verdict.
After inspection 2 and 6th gear are the only ones that look decent. Synchros, hib sliders and the other gears will have to be replaced in order to bring this transmission right away. Well time to build a bulletproof one down the road. As for now we also fitted the transmission with a new SPEC light flywheel.

After the install of a good working transmission along with the SPEC Flywheel, it was ready to hit the street to see how it feels. Oh yeah Amsoil synthetic 75W-90 was added to the mix. Shifts smooth as butter, Highly recommend adding this oil to your differential or transmission.

211whp run in the peach color was a run that was done back in 3/9/17.

Both of these runs were done at the same boost level 9psi, but the one the one that generated 218whp / 248wtq (purple lines) was done in a more hot ambient as per descriptions in the video. What a difference a proper working flywheel can make and when the right care if given all around to the the vehicle.

2013 Subaru STI – Stage2 Calibration

Category : Automobile Performance

Was the first day of fall, but with the ambient conditions that were present you would not think so. Another hot and humid day in Kenner, LA. We were working today with Scion tC as we installed a transmission on it and was adjusting the clutch on it and driving it on the street.

Got a call in the morning with a client that was wanting some one to look at his 2013 Subaru STi as it was not performing up to its standards. Managed to squeeze the client in at noon and told him that we usually calibrate the cars at nights since it gets really hot in the shop. He was coming in from MS and driving thru town on his way to Lake Charles and decided to call us to help him with his ride.

We moved cars around at the shop and got the AWD Dyno Dynamics ready for his arrival. Placed the vehicle on the dyno and got it ready to see what we could do to help matters.

2013 Subaru STi with stage 2 mods:

Stock engine / Cobb intake, APv3 /Grimmspeed Upipe, TMIC and catback exhaust
Tial BOV with EWG / Air pump delete / Cobb Fuel pump

Ambient conditions were 103F / 43% humidity and 30.03 Baro
Test performed in 4th gear

The vehicle was previously etuned and the client wanted a dyno calibration instead so we proceeded to accomodate him as he had some DTCs present that needed to be taken car of which were affecting his fuel trims and his over all WOT fueling.

Before the dyno pulls were done we checked the oil level and also discovered that we needed to add a quart of oil to the engine. In comes some Amsoil XL series 5w-30 to the rescue.

Before and after resutls from the tuning session. 261awhp and 288awhp was achieved.

Dyno jet simulated number vs boost which just hit 20psi and tapered to 16psi.
In conclusions the client was very happy and we thank Chris for trusting us with his ride and having patience in this hot and humid day which was not easy day to calibrate an engine.

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.
