ECU / ECM Tuning

Custom torque curve optimization, turbo response enhancement, and heavy-duty fuel economy tuning tailored to your route and weight.

Custom ECM tuning from Shokar Diesel recalibrates your engine's boost maps, fuel delivery, and timing for measurable 8 to 15 percent fuel savings and sharper throttle response on the grades that matter, from the Coquihalla to the Rockies. Our certified diesel software engineers build each map around your route, your payload, and your engine, whether it is a Cummins, Caterpillar, Detroit Diesel, or PACCAR. Most highway haulers and fleets see the tuning pay for itself within 3 to 6 months, with lower exhaust gas temperatures and better hill-climbing torque to match.
