I need a baro-correction for Overrun Kpa.

Post by montelibre »

I'm not sure where this topic should be.

I have an automatic jeep V8 running with MSX3.

I have updated my firmware from 1.4.1 to 1.5.1 beta and the Idle control works much better than before but, I think it can be improved a bit more.
I usually drive my jeep around differents heights, from sea level to about 2400 meters.

I have set my overrun at 23 Kpa. when it is at sea level this value works well, but when I am at high elevation (e.g. 2000 meters) this value is too near of the value for Kpa at idle speed (whit the automatic transmission at Parking position), and sometimes under 23 Kpa.

So, I think that It should have a baro correction for this feature. In this way, the CL idle Control always could work fine, in spite of the elevation.

What do you think?

I also think a baro% value might work better in this case.
