if you mean kpa?

take it that:-

250 kpa = 2.5 Bar

100 kpa = 1 bar

You can do the psi bit your self

1bar = 14.7 psi just incase :wink:

:D The Apexi measurement is in KG/CM2,so 1kg/cm2=14.22psi :wink:
I also have a conversion table program,not sure if it will 'e'mail though :wink: I could try if you let me know if you want it :wink:

14.7psi is atmospehric pressure at sea level
we are not far of sea level :wink: Also the ecu map is done for sea level ie 14.7 psi or 1bar.

Not being funny but any one that say thay can notice .2 psi is being anal.

when you go 2 bar and its 0.4 then it makes sense to use correct conversions :?

The thing is depending on where you live or you are driving depends on the atmospehric pressure so all the ecu i have ever seen are set so 1bar/1000mb (millibars) is at sea level this is so the cars will run correctly weather you are on Brighton sea front or up in the alps.

Most of the cars read about 1012mb (millibars) when we do data checks in our work shop.

If you want to get your boost setting spot on then use a manual boost gauge that has been calibrated. You cant get it wrong this way.

that was one of the legend that was 20legacy's favourite posts how he was increasing his boost by .1 increments :roll:

he even got antilag all animated with his incredible boost stories :lol:

Isn't Google great?

http://www.convert-me.com/en/convert/pressure

put ur value in any scale you want and get 17 other ways to say it :lol:


For example due to clutch probs I'm running 8psi

or
.5516 bar
55.16 KiloPascal
551.6 millibar
.5625 kgf/cm2
413.7 mm of mercury (Torr) as the standard gauge uses.


It does feel dog slow though :(

Still saw off a Clio172 and SLK320 in Milton Keynes on the way to work this morning though :)

know what you mean mate :wink: im actually below it :D i always thought 1bar=14.7psi too :? sounds daft but a boiler at my old work place used to sit at an indicated ten (147lb) bar all day long on a digi scale :?

So does the Apexi AVC-R boost controller read in kg/cm2 rather than bar or psi??
