PIM-2 comes pre-loaded with two fuel injection maps

Yoshimura has just released the next generation in fuel management systems for fuel injected off-road motorcycles and ATVs – the PIM-2 (Peripheral Interface Module).

According to Yoshimura, the PIM-2 installs easily, typically in under 30-minutes using simple Plug-N-Play technology. Just plug the PIM-2 into the stock wiring harness using the supplied sub-harness, mount it to your bike using the supplied mounting kit, and you are ready to race!

Yoshimura has been involved in fuel injection tuning for many years through its Superbike Racing program. Now, with the proliferation of EFI into the dirt world, Yoshimura has utilized this experience in creating the PIM-2.

The PIM-2 comes pre-loaded with two separate fuel injection maps for either a Yoshimura slip-on or full exhaust system. Maps for additional pipe brands or engine modification configuration can be downloaded from the Yoshimura website.

Yoshimura claims that the PIM-2 provides a noticeable improvement in performance and the ability to custom tune your motorcycle to virtually any preference or condition.

Current adjusting devices offer coarse adjustment. The PIM-2 offers a much finer level of adjustment to personalize your machine’s power characteristics. The PIM-2 features over 400 adjustment points in +/- 1% increments with full range mapping every 500 rpm at 10% throttle intervals. It comes with a Plug-n-Play complete wiring harness and is simple to install with basic tools. An instructional video is also included.

Nearly limitless custom tuning is now at your fingertips with a PC laptop and easy-to-use software. Mate the PIM-2 with Yoshimura’s optional self-mapping DATA (Digital Advanced Tuning Assistant) kit additional performance tuning either on the track or the dyno.

The DATA kit consists of an air fuel sensor and amplifier box that plugs into the PIM-2, and allows for self-mapping of a motorcycle or ATV. The DATA box automatically calculates the required fuel adjustment at each RPM and throttle position to reach the user selectable target air fuel ratio. The kit comes with all of the required hardware, but may require modification of the exhaust pipe to accept the air fuel sensor fitting.

The PIM-2 ($339.95) and DATA unit ($429.95) are available at your local dealer for all fuel injected models of ATVs and off-road motorcycles.
