The 2008-2009 multi-fuel engine control team updated the Phazer with a Microsquirt ECU, a similar ECU specifically designed for snowmobiles, ATVs and motorcycles. The addition of the Microsquirt ECU eliminates the 9000rpm revolution limit, as the Microsquirt supports coil-on-plug ignition. It also allows the team the opportunity to tune the sled for the optimal balance between fuel efficiency, emissions and power.

An updated computer and a touch-screen kit were implemented to maximize the usefulness of the onboard computer. These additions proved extremely useful, as acceleration testing would have been far more cumbersome without the on-board computer and the versatility it allowed.

The wiring of the sled was completed on November 25th, including the permanent installation of the ECU. In the months between December and February, the team worked with the MegaTune software to prepare the ECU for our application. The sled ran for the first time on the Microsquirt on February 13, and emissions testing was completed on February 24.

At competition, the team performed decently, passing the fuel economy and emissions events, though improvements could be made. In each of the endurance and emissions events, the team placed last of the teams who passed, earning an overall fifth place finish out of 11 teams signed up to compete.
