NOTICE: You are not purchasing an ECU but an ECU reprogramming service by sending your ECU in to us. This will not change your engine hours or override any mechanical problems that are hindering your engines performance. Your ECU is located on the port side of the engine and it is recommended that the battery be disconnected or power kill switch have power turned off prior to removal to prevent accidental electrical interference that can put the ECU into a factory lock down and not allow Nizpro Tuning to be performed.

The process of Tuning the ECU on the bench will set multiple false codes that will be stored in the ECU since it is not plugged into the engine. After Nizpro Tuning you can have the codes cleared out by a Yamaha dealer to start out fresh again.

To get the process started just add the correct Tune option to your cart and check out and then include your information in the box with your ECU and ship to using the address below.
Tuning is generally a 24hr turnaround when we have your engine model and ECU number ahead of time.
Return Express shipping with $1,500 insurance and signature confirmation is included at checkout but it is up to you to properly package, ship and insure your ECU to us.

When shipping your ECU please include the boat year and application in “message from customer” section and ship to:
Three Rivers Tackle

West Richland, WA. 99353

Attention: Please Read prior to purchasing the Nizpro PoweringServiceand call if you have questions: A Nizpro Tune cannot compensate for a poorly running engine if there are other factors causing a loss of performance that need addressed first. Results can vary for every application due to differences in vessel weights, hull design, altitude, engine height, prop pitch and efficiency.
