Ford Focus RS - Dyno Preparation
Dyno Preparation - How To:
In order to get the most precise dyno results with the Focus RS, it is necessary to disconnect power to the Rear Drive Unit, or RDU. This procedure is necessary for all dyno types including AWD Dynos. To read more about why this is necessary, follow this link: http://www.cobbtuning.com/ford-focus-rs-power-gains-and-development/
Disconnecting power to the RDU can be done very easily by disconnecting one plug underneath the vehicle. Follow the step-by-step procedure below to do so:
- The plug that you will be disconnecting is located underneath the car, just above where the driveshaft meets the RDU.
- ENHANCE!
- This plug has a single plastic clip that will need to be depressed in order to pull the plug out.
- Once disconnected, tuck the clip clear of the driveshaft, as the driveshaft will still spin when the RDU is disconnected. This portion of wiring harness is pretty short, so leaving it dangling should be safe.
- With this plug disconnected, you'll see the following messages displayed on the instrument panel:
- Now you're ready to hit the dyno!
- Once you're done on the dyno, just plug the connector back in.
