Dave Gingras built D Spec from hands-on bike work to a specialist ECU-mapping shop that serves Canadian factory teams and top amateurs. This brief explains his path, what D Spec does, and the measurable ways his tuning and race support affected the 2026 season.
D Spec focuses on ECU mapping and tailored fuel/air tuning for motocross bikes, supplying Canadian factory teams and top amateurs.
Gingras combines mechanical background, trade-school machining skills, and years working at dealerships to deliver race-weekend support and season-long OEM-level mapping.
D Spec is an ECU tuning and mapping business run by Dave Gingras. The company provides custom ECU units and mapping for race teams and serious amateur riders. Tuning adjusts the mix of fuel and air and other engine parameters to suit rider weight, track conditions, altitude, and specific bike setups. That fine-tuning can change throttle response, power delivery, and consistency across a race, which teams look for as a competitive edge.
After several years at a shared motorcycle repair shop—doing street bikes and dirt bikes—Gingras founded D Spec in 2018 at about 28 years old, choosing to focus exclusively on dirt-bike performance.
He also served as a mechanic for Red Bull KTM Canada Fly Racing Team during the season and was on-site when Crayden Dillon won a moto at Round 5 of the Triple Crown Series in Riverglade, New Brunswick. Priority MX won the WMX championship, and riders tuned by or working with Gingras achieved podium finishes across classes.
Gingras blends bench ECU mapping with on-track setup and tuning. His race support includes pre-season and in-season mapping, and hands-on adjustments at rounds when teams need immediate changes. He describes a long summer schedule of race weekends and map work, then dialing back after the season to begin development for the next year.
D Spec operates between dealership-level service and factory engineering. Teams that need ECU specialization or riders wanting specific power traits come to Gingras for a focused service that standard dealer maps don't provide. His machining and electronics background supports deeper diagnostics and hardware-aware tuning.
Gingras indicated he was already working on development for the following year while closing out the season. Expect continued collaboration with factory teams and incremental improvements in mapping strategies, as well as ongoing race-weekend support for clients who campaign national or regional series.
