      I'm going to answer my question with a qualified "yes". A replacement cluster eliminates the dim brake warning light on the dash, and nets this result in the AWD controller:

      While logging on wet pavement today I felt the front wheels losing traction. The ABS light came on, and along with it I realized the Haldex quattro system isn't functioning. Considering the...

      But not so much when the diverter valve is opening as it should be. And that's the salient point: his symptoms come with the diverter valve releasing pressure. This whole issue has the feel of...

      Well, I know you and a few others out there on the interweb have axes to grind. Go ahead and grind away.

      This is some pretty wonky stuff I'm posting here, but I want to show how the changed flowmeter (MAF) housing effects what the ECU "sees" and how to correct for it.

      The internal bearings in your turbo are shot. Metal debris in or outside the turbo could have contaminated your oil galleries and prevented sufficient flow. When the bearings went, the rotating...

      The OP is one of our first customers to take delivery of our newly-improved F23 turbo with an Anti-Surge compressor wheel. And his car was a great demonstration platform for showing off the turbo's...
    8. TT225 MAF sensor specifications

      We have a number of customers running our F23 turbo product in their TT225s, and while tuning them we always have to be mindful of the subtle differences between the early model year cars and the...

      Our most recent dyno has the car flirting around 300whp. But at the time the file was closing throttle to intervene against the load values. So the chart is uneven.

      Dan - even back in 2012 when these original tests were being done the F23 didn't have a 2283 compressor wheel. That BorgWarner wheel's susceptibility to compressor surge in a 1.8T was old news even...

      Not sure of the maximum power this MAF configuration will support, but it's certainly able to meter for more air than is possible in a stock 70mm housing. Here are the measurement gamuts compared:

      We're carefully raising the boost/power on this unusual setup. Making use of Eurodyne's BoostManager, we are able to define a boost curve that ramps upward to match increasing engine speeds. Here...
    14. moving to a new air metering strategy

      It's time for some experimentation. For some time I've wondered what kind of impact a change of airflow scaling has on these ME7.1 type ECUs. So, with C2's leave, I have changed the MAF sensor...

      Would you consider converting the car to a wideband Lambda-capable ECU like an AWP or BEA? Tuning on the more modern ECUs is much easier.

      It's good to see increasing tuning support for the platform. Here's an interesting graphic laying out their argument for N/A power. That hp figure they're quoting is pretty darned good:
