how to change reading from Kpa to Psi on a microsquirt

[davidsproduction]

Greetings,

I have a microsquirt V3 Case and i would like to change it from reading Kpa to Psi. Where in the setting can i do this?

Regards,

im not not sure that you can do that, if you have a paid version of tuner studio you can swap one of the gauges to be a boost / vac gauge if you want and megalog viewer can convert the kpa to psi for reviewing datalogs but i think the load sites on the tables fuel,spark ect have to stay in kpa

Since the ECU does its calculations in absolute pressure, trying to render this as gauge pressure could end up being more confusing in the long run than getting your head around the kPa readings. There are two ways one could deal with it:

1. Have the zero point set to an arbitrary value. Result - depending on the weather and the car's location, you could see 1-2 psi of boost or vacuum with the key on and engine off.

2. Have the zero point actively move as the ECU updates its barometric pressure readings. Result - the load axis of the table and kPa based settings could move around while you're driving.

Does either one of these seem preferable to getting the hang of kPa? (That's not meant to be a rhetorical question - I'm seriously wondering if you would prefer this.)

Something discussed in the past is to put an optional 2nd column on the Y Axis as a reference. That could let the numbers change based on ambient changes, but the kPa would still be there, stay consistent and drive the tune.
