Hi

Does anyone know what the formula needs to be in excel to convert the load into PSI that comes from the Megajolt when you do a datalog.

Thanks

Hi,
14.7 psi is 1 bar or 100 kpa.
Remember anything below 100 kpa on a MAP sensor is a vacuum, so 200 kpa will be 14.7 psi of boost.
I'm guessing the scale is in kpa?
Cheers,
Gavin :)

a hah. 14.7 psi is one atmosphere.


1 atm = 760 torr = 14.7 psi.

Bar
(bar) The bar nearly identical to the atmosphere unit.
One bar = 750.062 torr = 0.9869 atm = 100,000 Pa.

there you go :)

Evo is correct.

1 atm is a average of the pressures we all expereince, as you know they change regularly!

So in our own way we are both correct. I don't thing 0.2 is going to make much of a difference anyway, not if reading my boost gauge is anything to go by.

Hi,
So we're all correct, but we've still not answered the question!
So ... multiply the number from MJ by 0.1450377 to get psi :)
