Dyno testing and diagnostics
A measured answer instead of a guess. Baseline pulls, wideband logging, and fault diagnosis on the rollers.
About the shop
About us
A calibration shop first. Every map we sell was developed on our own dyno, on a bike or car we had in the building.
SFN Tuning is a calibration shop that happens to sell parts, not a parts shop that dabbles in tuning. Every file we sell was developed here, on our own dyno, on a bike or a car we had in the building.
How this started
It started with one S1000RR and a stubborn flat spot that three shops had told the owner was normal. It was not normal. It was a lean cruise region in the factory map and a heat-soaked intake temperature sensor, and it took a wideband, a full afternoon on the rollers, and a willingness to keep going after the easy answer ran out.
What we will not do
- We will not sell you a file for a bike we have never had on the dyno.
- We will not quote a horsepower number we have not measured.
- We will not flash a sick engine. Adding power to a problem is how engines end up in pieces.
- We will not pretend this is emissions legal.
What we do most
Straight from the bays
What this includes
ECU flashing and calibration fitting
Bring the vehicle in and we do the flash for you, with a dyno verification pull included.
Engine rebuilds
Full strip, measure and rebuild for bike and car engines. Everything measured against spec and written down.
Come and see it
Bring the vehicle. Ask the awkward questions.
We would rather spend an hour talking you out of the wrong parts than take your money for them.
