Since 2004, Westside Powersports for expert high performance tuning to maximize the power output of your SeaDoo Spark. There are no modifications, we flash tune the ECU on 60hp and 90hp engines.

​

Why performance tune your SeaDoo Spark? Experience faster acceleration, improved throttle response, higher RPM limit and Unlock Sport Mode are great reasons for a performance tune. There is no change in fuel efficiency or engine reliability.

​

ECU tuning also includes;

• clear engine codes.

• reset the security code.

• reset maintenance records.

• review RPM rev limit and history.

• Dess program the key(s).

​

We recommend 93-Octane fuel and Amsoil full synthetic oil. All SeaDoo's, including Spark, run better on 93-Octane, and if possible, use non oxygenated gas without ethanol. For example, 91 non-oxygen is equal to 93-oxygen.

​

Shipping: please package the ECU carefully and include your Name, return Address, Phone and email.

​

NOTE: a $10 per month late charge after 30-days without payment. We do not want the ECU, but do expect payment within 1-month on a service that you requested. After 3-months without payment, your ECU will, unfortunately, be forfeited.

​

Warning: the excess power from a flash tune can produce an adrenaline rush causing the rider to operate the SeaDoo beyond it's limits. Secondly, tuning is not appropriate for older engines that could blow a valve or engine part. We are not responsible for SeaDoo's not operated or maintained properly.
