Pesky boost control hehe.
Better off with a HDi90 as a starting point
Are those sensors calibrated on absolute boost then, ie, 1 > 2.5bar giving you your 0 > 1.5bar boost range?
So the 3 bar sensor is a 1 > 4bar absolute sensor?
I've never looked too deeply into those calibrations on the HDi110 but I expect they are relatively trivial to swap around like MAF etc. I guess the bigger issue is if you fit a big FMIC for a 406 HDi 110 is getting an appropriate connection and/or loom adjustments etc so the sensor can be sited appropriately.
Have you ever logged the sensor output Steve? Just curious if they have much more overhead and are just mapped with a narrow range, or really do run out of range.
