Boost gauge in MegaTune

When I view my datalogs with the viewer, I'm able to enter in my kPa value for the engine when it isn't running. It's 97kPa. I've selected to have a boost gauge in MegaTune, but is there anyway to give it my kPa value with the engine off so it will be calculated correctly?

Bump since I would like to know also.

Appearantly no one knows about this feature.

wasn't this the same as your other question? it'll show atmo when the car is off right?

We're talking about the ability to change the gauges in MegaTune. You have an option to display a boost gauge, but the boost calculation can't be accurate if the MAP isn't calculated into the equation. That's what we are asking. Is the MAP (with the engine off) automatically recorded so if you select to display the boost gauge the reading will be accurate, or is there a field where you specify what your MAP is and it calculates it from there.

You saw the datalog I had that showed 10psi in that Java log viewer. To get that value I had to tell it what my inital MAP value was and it calculated that into the MAP values of the datalog to read boost. Obviously in my case anything above ~97kPa would be considered boost.

Directly from the INI file. Looks like barometric pressure is taken into account.

Code: Select all

boostgauge        = boost,             "Engine Boost",           "PSIG",  0, 20, 0,  0,  15, 20, 1, 1
boost  = { map < barometer ? 0.0 : (map-barometer)*0.1450377 } ; Calculate boost in PSIG.
