The Dynojet Power Commander V is a vital first step into the world of motorcycle fuel tuning. The ability to adjust your motorcycle’s fuel map is vital if you have added a high-flow air filter, aftermarket exhaust system or smog block-off plates. All of these modifications will, in some way, alter the air/fuel ratio in your engine. The Dynojet PCV, with its microprocessors and PCV Software, allows you to adjust your motorcycle’s fuel map up to +250%/-100% to ensure an optimal setting. Dynojet offers a large database of free, downloadable maps for many combinations of motorcycles and aftermarket parts.
