Rep Power: 282 The MAP sensor measures pressure inside the manifold. So on a turbo car under boost, it measures the increase in pressure.
Not a problem so far, but the engine ECU is not programmed to measure positive pressure, so it cannot read it. An isolation valve bleeds off the positive pressure.

Rep Power: 0 You voltage clamp the map sensor so it never sees boost
For example, the car will read positive manifold pressure at 5 volts via the map.
To bypass that you get a voltage clamp and set it for 4.7 volts so the map sensor will never read boost and get confused.

You might have the voltage to low. If you do try setting it closer to 4.7 with a volt meter.

EDIT: My conclusion right now for you, without talking to anybody is that you're voltage is clamped too high. What the maximum votage at WOT? It's either 4.5 or 5.0V. I'll still try to find out for you... but I think 4.4 might be too high.

Rep Power: 0 You used to have to be a dealer. But they are still hard to come by. If it says lower... then up the voltage at the RPM the light comes on. (This is exactly why I said I wish I had logged all of this).
If you want to borrow the cable (and the software if you need it) once I have my numbers, PM me... we can work something out (free of charge).
