Y axis in kPa rather then %?
 
The Y-axis of tables (fuel, ign, afr etc) are all in % (of what, 250kpa?).
It seems more logical to have these directly in kPa, how would I do that?

Am I right that % equals kPa? So if I enter 180%, this would be 180kPa?

If you have set your control algorithm to "speed density" which you will and should have - the % are the kpa.

I haven't played much with my MS2 lately, but IIRC % = "Percent Baro", not absolute pressure (ie kPa). There is a setting somewhere to switch to absolute MAP pressure instead of percent baro.

MSx/Extra EFI • View topic - Megatune showing %, not KPA, also acting weird

thx, I'm using speed density, so it's kPa. I'll have to change my tables from 100% to 200% :)

Try using the MSPNP maps for fuel and spark - shuold give you a good starting point.
