Kpa/Boost

[rtviper]

What is the conversion for Kpa to boost. My car was tuned on a dyno and the target a/f and spark advance all read in Kpa. I am trying to see at what boost the timing changes to 18 degrees max and the a/f goes to 11.2 They both occur at 178 Kpa. I assume you cant really tell by looking at these 2 charts where the boost actually reaches the 22lbs that was used on the dyno. Both the a/f and timing reach their max 18 degrees and 11.02 at 4700 rpm with a 4500 rpm stall They never go above this setting the reast of the way on the charts Thanks

If you have no calculator, 100kPa ~= 15 psi ~= 1 bar. Every 10 kPa ~= 1.5 psi ~= 0.1 bar.

If you have a calc, 22 psi / 14.7 ~= 1.5 bar of boost. 1.5 bar of boost is 2.5 bar of MAP, which is 250 kPa of MAP in the map.

178 kPa MAP is ~ 0.78 bar of boost, which is ~= 0.78 x 14.7 = 11.5 psi boost.

this is what i have

I am glad the gen 7 system uses PSI. Makes you feel so much better that you dont have to convert

FAST can log boost......

Both fast systems can record map PSI
