Fuel Controller 

Brand SKU: 9430032


The MBRP Race cans for the Arctic Cat Thunder Cat ('17-'23) and the Yamaha Sidewinder ('17-'23) require this fuel controller to be installed along with the can. 

The EJK evolved out of the need to address the ever-increasing complexity of factory fuel injection. For the newcomer to the market or professionals wanting an easier method for tuning fuel injection, the EJK is a customizable solution for the shop that wants to take control of their tuning needs.

GEN 3 is the short term used to describe the Generation 3 Electronic Fuel Injection (EFI) controller manufactured by Dobeck Performance. The GEN 3 was released in 2005 under a private label program. The GEN 3 is a piggy-back EFI controller because it does not replace the stock ECU, but rather monitors the signals to the injectors and makes fuel adjustments based on the mode settings. The GEN 3 has a push button interface allowing access up to 6 different modes to allow for quick fine tuning by the end user without needing a computer.

The GEN 3.5 EFI controller is an extension to the GEN 3 controller. The GEN 3.5 technology was released in 2009 also in the DP private label program. The GEN 3.5 controller has the ability to add or pull fuel within each available fueling zone.
