Just scanned using the BTT and found this code 30FE with this kPa amount 186.00 and another of 165.00 in front of the throttle valve. which if these are 'kilo pascals' this is 26 and 23psi respectively. A tad bit high if you ask me. I have JB3 and LOVE it.


EDIT: I'm retarded! I looked it up a bit more... I now realize that you take 100kPa and subtract it from whatever the total amount the ECU logged. Whoops.

In this case the ambient reading was

which is hectopascals not kilopascals...I know confusing.

Anyways that is about equivalent to 97.6 or rounded to 100 Kilopascal.

That is the ambient air pressure before boost is applied.

You then subtract the pressure reading at throttle valve of 167 kpa and you get:

167 - 100 = 67 kilopascals of boost above normal atmospheric pressure.
If you then convert the 67 kpa to psi you get about 9 psi of boost pressure above normal atmospheric pressure.

So Mike was right and I was wrong.
