Couple weeks ago was the last round of TRIPLΞCROWN canadian motocross championship WLTN Raceway . The year 2026 marked my 3rd season being part of the KTM Canada racing team. Had the opportunity to spin the wrenches every week-end for Crayden Dillon . Grateful to have the chance to work alongside Nicolas Hébert who pushes me to build dirtbikes to the absolute pinnacle.

I was also fortunate enough to have the Priority Mx and the AVL MX team rely on our engine packages and ECU tuning to make their bikes grab holeshots but also make it to the finish line. Congrats to Jamie Astudillo for winning the WMX championship. Also congrats to Tanner Ward for hid 3rd place in the 450 championship and Josh Boaz for his 3rd place in the 250 championship.

Special thanks to the privateers that also trust D-spec to bring out the best in their machines. We had the chance to work with over 20 riders that races this serie, all with great succes. I've started D-spec in 2018 and the 2026 summer is the busiest I've ever been. The amount of experience acquired adds up and is shared among everyone that dials our phone number. Looking forward to raise the bar even higher for 2027. See you at the track.

Most riders know ECU tuning exists — but very few know what the ECU actually controls.

Modern bikes do far more behind the scenes than most riders realize. Throttle response, ignition timing, fueling, engine braking—mapping influences nearly every aspect of how a motorcycle behaves.

I wanted to explain what’s really happening inside a modern ECU, and why tuning changes much more than just horsepower numbers.

La plupart des riders savent que la reprogrammation ECU existe, mais peu savent réellement ce que l'ECU contrôle.

Les motocross modernes font beaucoup plus de chose en arrière-plan que l'on pensent. Timing d'allumage, réponse du throttle, comportement du frein moteur, limiteurs de régimes... La map influence presque tous les aspects du comportement d'une mote.

Je voulais prendre le temps de vous expliquer ce qui se passe réellement à l'intérieur d'un ECU et pourquoi une bonne calibration influence bien plus que les simples HP.

Capteurs, ignition timing, throttle response, engine braking and fuel mapping — this article dives inside the real logic of a modern ECU and explains why tuning has such a massive impact on the way a motorcycle actually feels to ride.

C'est l'heure d'une retraite bien méritée pour le race Bike 2025 de Alexandre Gougeon . 97.5 heures totales sur un bike très sollicité avec un entretien standard et aucun pépins mécaniques.

Safe to say our snowbike Power Package for the austrian 450s and 500s was put to the test for the last few winters. Great power and even better ridability helped many riders such as conquer the gnarliest terrains.

The power package incorporates the incredible exhausts and intakes from and a perfectly tuned GET SX1 PRO ECU to match this combination. ECU with mapping available separately if you already have the RP exhaust and/or intake.

First post was to catch your attention. This one is for the geeks.

2025 was once again a year of building fast bikes, pushing our limits, winning races and working with incredible people.

We keep on refining our craft to make sure this upward trajectory stays the course and to maintain the great relationships we've had the chance to build.

Cheers to all the D-spec supporters.
On to 2026. 🚀
