UGBeta — end of August
ME7Tune
VR6
The 12v VR6 build is running. 110 named maps and values, the load caps opened up for boost, launch control and a MAF housing calculator — all working against a real 021906018.
Beta targeted for end of August · No pre-orders · No deposit
KFZW base ignition on the 12v. Table and surface side by side, the same as every other platform.
Where it
actually is
021906018 — the 12v VR6, 1999.5 to 2002, manual. Everything below is working against a real stock file, not planned.
Boost
Load caps opened up
The VR6 is naturally aspirated from the factory, so the stock calibration caps requested load where a stock engine would never go. Those ceilings are editable here — the volumetric flow limits across the rev range, and the two byte-level caps patched into the code. Raise them and the ECU will actually ask for the air a turbo or supercharger can supply.
Calibration
110 named maps and values
Timing, fuelling, the torque chain, idle and sensors — named, scaled and checked cell by cell against the stock binary. Each one has a plain-English note on what it does and what changing it will do, not just the factory German label.
Tools
Launch control & MAF rescale
The 2-step patch installs with ten editable parameters — launch rpm, retard, cut duration, arming conditions — and comes back out cleanly. The MAF calculator rescales the sensor curve by area when you fit a different housing, which you will if you are moving serious air.
The breathing curve across the rev range, and the two byte-level ceilings under it. Both normally need raising together.
Also in
Configuration editors
Output stages and the exhaust-side configuration are editable as named switches rather than raw bytes, with the ME7.1 bit layout built in. Useful when the hardware on the car no longer matches what the factory expected.
In progress
Flashing and logging
Both use the same code that already runs the other platforms. The VR6's logger definitions are bundled — 520 channels — and there is more work to do on the logger side before it is signed off. That is the main thing between here and the beta.
Patched in, with launch rpm, retard and the arming conditions all editable. It comes back out cleanly too.
Housing calculator above the curve it rescales — 73 to 83 mm is 29% more air, because the scaling is by area.
If you have a 12v VR6 and want to be on the beta, get in touch. Beta pricing while it earns its miles.
