BRZEdit MAP scaling - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

jamesm · 08-26-2013, 01:40 PM

My tuner is having a hard time figuring out how to scale the MAP sensor (4-bar omni) on BRZEdit. Is MAP sensor scaling officially supported by BRZEdit? Maybe @epifan can chime in? Thanks.

I will await @mad_sb 's response. These kind of questions are the reason I haven't bought BRZedit yet to give tuning my car a shot.

Yes the scaling tables are in there. What problem is he having?

mad_sb · 08-26-2013, 03:29 PM

Yeah, there are two tables. One lists the zero volt offset and the other is the volts per bar. It must be a linear output sensor. They are in the 1d tables. Shoot me the sensor model number and specs via pm if you want me to try and figure it out.

EDIT, I found this from a real quick search. this should be what he needs will verrify when i get home:

bar/volt .833
offset (bar) .012

Easy enough to test, check an external barometer, key on engine off turn on logger, compare reading

Yeah, post the model number if you can the data i found was for a perrin omni-4bar. May or may not be the same.

I'm almost certain that is correct.

Can check later today.

the part # on the sensor is 'MAP-K-4BAR', two other numbers on the package are 'P0-000022227' and '032113'. hope this helps. thanks!

@mad_sb

would this be the same for the 3 bar AVO sensor??

i would imagine not, 4 bar vs 3 bar will have different scale factor for sure.

AVOturboworld · 10-02-2013, 12:43 PM

3 bar has different scaling than the 4 bar.
3 bar setup:
pressure (bar) offset: -0.0113
scaling: 0.629
