Dyno Procedure
In order to properly dyno the FK8 Type R, there's a couple things to be aware of.
Fully disable VSA with the pedal dance
In order to not have the VSA system flip out when you're on a dyno or otherwise interfere with your results, you need to fully disable the system with the pedal dance.
If you do not do this, you may be unable to engage your parking brake and all stability systems will be disabled for an extended period of time, sometimes over 30 minutes. It is not known how to force this to clear, except by reflashing the ECU.
How to perform the pedal dance
Start with the parking brake engaged. Cycle VSA by holding the VSA button for two seconds until the VSA light turns on, and again until it turns off.
- Push and hold brake pedal, disengage parking brake
- Cycle VSA
- Engage parking brake, release brake pedal
- Cycle VSA
- Push and hold brake pedal
- Cycle VSA
The VSA 'OFF' light should be blinking and you should now be forced into sport mode. Don't forget to release the parking brake before you start rolling on the dyno.
Heat soak will majorly impact results
The FK8 ECU pulls a massive amount of power due to high IATs. Maximum boost starts getting reduced as early as 25C/77F but the power loss becomes significant at 140F. It is vital that you let the engine bay cool down before and in between runs. It is easy to lose well over 50 lbft of torque just by being heatsoaked at the start of the run.
