What TTS base tune was he running? (Scott will probably have to answer). The latest TTS base tune; "Rocket 3 SC disconnectedmapsensorbestmap.dat", goes
WAY rich at WOT.
I've never been able to figure out why Richard decided to disconnect the MAP sensor and stepper motor, especially since it's so simple to keep them. I've been running a 2 bar sensor since day one with the SC. I even posted a "how to" here on installing a JayCar DFA to convert the MAP voltage for the stock ECU. Guess it's one of those "not invented at TTS" issues.
Good on you for helping Scott to avoid future problems (ceramics and knock system).
