Like heading says, need this so i can data log.

It's the one Josh (Rogue Tuning) uses for the Chips and I think it's the same as the Vittesse one?

You can use this simple equation:

pressure = 9.1158*volts - 14.539

Kpa to psi is straightforward:

Kpa * 0.145037738 = psi

That is, of course, absolute, so you will have to subtract the result by 14.7 to account for atmosphere...

I don't understand. I should of been more clear maybe.

Either KPA or PSI will be fine. All I'm looking for is 0.01 = x (psi/kpa) and 4.9v = X(psi/kpa) so i can put it in the data logger to show the boost reading.

.25volts = -12.26psi
4.85volts = 29.67psi
