Boost reading
Got my tunes from Matt and was VERY disappointed. I talked with Larz at Gearheads and he suggested that the connection to the MAP sensor that my Attitude monitor uses to register boost was the problem. After removing the connection, NOW I see what an SCT can do for you. 2 questions: first, why does removing that connection seem to make so much difference?; second, how can I measure boost with my Attitude monitor without messing up the SCT? I use the Attiude to register RPM, EGT, and formerly boost. I am not running the Edge (set on zero). I have a ScanGaugeII but like to leave it on volts, EOT, ECT, and TFT.

Not sure, but 2 extra sensors to what? I'm in over my head since I didn't install the Edge myself. Don't know why the problem occurs, why disconnecting from the MAP sensor fixed it, or how to get the Attitude to register boost without causing the same problem.

No, the gauge is on the Attitude monitor. My ScanGaugeII is in the OBDII port.

I see the Edge was plugged into the MAP.
It may of been loading the circuit so the PCM
was having problems with the tune.
The boost fooler tricks the system into
thinking that the boost is not where is really is
and the system responds with more boost.
You should be able to add 2 extra sensors
to the Edge. That may be how you have to do it.

I think you're right about the Edge, hence it is being "mothballed" in favor of the SCT. I'm just using the Attitude monitor.
