The past few weeks I’ve spent assembling and wiring a variety of sensors into the car and I’m finally reaching the point where I can make some recordings.

Here is a comparison of the manifold pressure on K03’s with a Stage 2 tune versus the exhaust pressure just prior to the turbocharger turbine inlet.

I’ve still got some more work to do with the car, this is an early release version of the TorqByte water-methanol system controller, it is a replacement for the Eurodyne BoostManager.  The TorqByte group are the people who put together the guts of the BoostManager and since Eurodyne stopped supporting BoostManager the TorqByte group has picked up the product and are making some nice enhancements to it.

I picked up a 3 bar MAP sensor in anticipation of installing a pair of BorgWarner K04’s.

Some of the dimensions of the two:

Concern about the accuracy of the MAP sensor on the car led me to removing the part and replacing it with a new MAP sensor that I had in my tool box.  I went and took a second set of logs with the new sensor and made a comparison.

It looks as though the old sensor is still functioning correctly.
