Provided that boost cut is turned off, and the and the map sensor reads SLIGHTLY above the rated boost pressure(3bar) how will the ecu react? Will it maintain the fuel delivery for the last bar of the fuel map (which will eventually go lean as pressure rises above that point), or will it failsafe an cut all fuel? Anyone have that experience?

I need to get to 30psi and need about 2psi extra for safety. Also is there a way to trick the m/sensor to handle more boost? Perhaps in the calibration settings.

Thanks

It will maintain the last load range. It just sees voltage from the MAP sensor. Once that's pegged, it has no idea if its running at the limit of the sensor or 50 psi over the limit.

Could anyone make suggestion if and how I could use the calibration settings to allow the ecu to read 32psi on a 3bar sensor?

It's impossible. The sensor won't read 32 psi. The only way you could get it to show 32 psi at the max voltage of the sensor is to tell the ECU you're running a 4 bar sensor and fudge the calibration. The E8 probably won't allow you to do that though because they always balk at custom calibrations.

Thanks for the info.
