6. Since you already made sure the throttle plate was completely closed click OK to continue. Next, the

following prompt will display:

7. When the prompt above displays, have an assistant fully open the throttle and hold it. While the throttle is

held in the fully open position click OK. Immediately after you click OK, you will see the following prompt:

8. Tell your assistant to release the throttle. Click OK and the Cannondale Dealer Tool will send the open

calibration file (which now includes the new values for fully closed and fully open throttle) to the vehicle

ECU.

When the send is completed, the vehicle ECU will automatically power itself down - the green LED on the

data cable block will go out. Communication from the software to the ECU is now shut down. To re-

communicate with the ECU, you will have to power-up the vehicle once again.

9. Power-up the vehicle ECU and click on the MONITOR ECU Parameters button. You are looking for the

“Throttle (%) Open value.”

Now, make sure the ECU parameters display is in the Continuous mode. Adjust the idle adjustment screw

so that the “Throttle (%) Open” value increases by 3%. For example, if the value was 2.3 with the throttle

plate fully closed, you need to adjust this to approximately 5.3 to ballpark the throttle plate position enough

to achieve idle.

Start the engine and allow the vehicle to reach operating temperature (70°C) and fine tune the vehicle idle -

setting as specified for the vehicle.

Refer to "6 - ECU Monitor" starting on page 13.
