About Us
Want to know more about us? We’re happy to talk cars and calibration — and we promise not to spill coffee in your pride and joy.
Who we are
We’re a small, engineering-led outfit focused on one thing: BMW E36 straight-six tuning with the Siemens MS41 ECU. We build, drive and tune these cars ourselves — road and track — so our calibration work is grounded in real-world experience, not theory alone.
The aim is simple: repeatable, reliable power with OEM-grade drivability. We pick parts that fit and perform, then map the ECU to suit modern fuels and your hardware.
What we do
From Stage 1 calibrations to cams, ITBs, stroker builds and forced induction, we align the calibration with the hardware so the car feels cohesive, quick and predictable.
We keep factory diagnostics intact, use proper logging, and iterate on the dyno and road until the data — and the drive — are right.
Still flying the E36 flag?
Same here. We run our own E36 328i builds — street and track — so we know what survives hard use and what doesn’t. If you want a stock-plus daily or a weekend circuit car, we can map something you’ll enjoy every mile.
Ask us about sensible bolt-ons, MS41 upgrades, and packages that deliver real-world pace without ruining manners or reliability.
E46s aren’t new to us
Although this site focuses on the E36, we also work extensively with the E46 M54 platform. If your garage has both generations, we can help you tune them consistently with the same data-driven approach.
Need MS43 support as well? No problem — we keep the same priorities: quality parts, robust calibration and OEM-like drivability.
How we help
We collaborate with other tuners and builders, locally and worldwide. Results matter more than ego here — if our experience with the MS41 ECU and the E36 platform can help with a turbo, supercharger, ITBs or big cam setup, we’re happy to lend a hand. For turbo hardware we rate K64 Performance, and for MAP conversions Hopwood Motorsport.
Watch What We Do
What people say
“Stage 1 felt OEM but stronger everywhere. Smooth torque and sharper throttle.”
— Chris M., E36 328i
“Cams + ITBs tuned properly — crisp throttle and stable idle. Exactly what I wanted.”
— James W., 328i track build
“Turbo calibration is spot on. Pulls hard but still drives like stock around town.”
— Maya K., low-boost GT30
