ECU Tuning
Custom-mapped flashes on MHD, Bootmod3, COBB, Syvecs and JB4 platforms. 93, E50, E85 fuel maps with valet, sport and race-mode switching.
A European performance shop run by ex-racing engineers. Real dyno work, real track data, real numbers on your build sheet. BMW M, Porsche, Audi RS, Mercedes-AMG.
Every car leaves with a printed dyno graph, a logged WOT pull, and a spec sheet. If we can't prove the gain, you don't pay for it.
Specialization beats a do-anything shop. Every job we book falls into one of these four pillars. And the technician who plans your build is the one who turns the wrenches.
Custom-mapped flashes on MHD, Bootmod3, COBB, Syvecs and JB4 platforms. 93, E50, E85 fuel maps with valet, sport and race-mode switching.
Coilover install, corner-balance, alignment to track spec. Öhlins, KW Clubsport, JRZ, MCS. Set up to the driver, not a spec sheet.
Big brake kits, J-hook rotors, Pagid / Endless / Ferodo pads. Bleed with Motul RBF660 and pressure-tested before you leave.
Pre-event tech, fluid swap, harnesses, fire bottle, AiM data logger setup. Same-day on-track support for your weekend at Big Willow.
Our Dynojet 224x AWD chassis dyno sits in a climate-controlled room with 18,000 CFM of intake-air balancing. You'll watch the run from the spec deck. You'll leave with the graph.
Test vehicle: 2022 BMW M3 Competition (F8X · S58). Stock turbos. Stock fuel system. 93 oct → E50 blend.
Built around the BMW M3/M4 Competition S58. But the logic is the same on every platform. Each stage is a complete package: hardware, software, dyno time, fuel-map calibration, and a printed result.
We don't claim to tune everything. Here's the honest matrix. What we do in-house, what we partner out, and where we'll politely send you elsewhere.

Filtered for cars Apex Tuned has wrenched on. Times verified against AiM Solo 2 DL logs. Cones count. No exceptions.
"Brought the M2 in expecting another shop that talks big. Got back a car that pulls cleanly to redline on 93, holds boost on a 30-min track session, and never throws a code. They explained every line of the map."
"I run Hooked on Driving instructor weekends. Apex is the only shop I trust with the GT3. Corner-balance was sub-2mm, brake bias is dialed, and the car is two seconds faster around BW than when I bought it."
"Honest shop. They talked me out of a built motor I didn't need and put the money into suspension and a proper alignment. The car is faster than it would have been with 100 more horsepower."
