converting map volts to kpa

[scott0999]

how do you do this for a 1bar map?

I would guess use a datalog? I don't know if I have any old ones or not.

hmm yea i dunno, youd have to figure out how to convert 0 to 5 volts into 0 to 255 dec lol

cuase all i know is .369 * (0-255) + 10.35 = map in the tunerpro/scannerpro

its showing up volts in the datalog

just change it to
.369000 * x + 10.35

[scott0999]

just change it to
.369000 * x + 10.35

using that formula 1.8 volts is 11kpa??

[sil]

factor should be 0.369000
offset should be 10.350000

all .ads files i have seen that have the map in kpa, read 10.35 in the display when not connected lol
they all use that formula

think its got sommin to do with real atmosphere and then what the intake sees
cant exactly remember why
