How to convert KPA into pounds of boost??

[nitrorocket]

I have been turning up the boost more and more. I want to make sure a am well over 800 RWHP next time I hit a dyno on 93 octane.

My question is, how do I convert the KPA READING OF 227 to lbs. of boost??? Do you think this boostnumber from the Map sensor 100% accurate, even over a boost gauge??:)

I believe the conversion is 6.895 kpa = 1 psi. I'm going off memory but it should be close

A MAP of 277kPa is equal to a boost pressure of approximately 175 kPa. (You have to subtract 102 kPa which equals 14.7 psi-- atmospheric pressure.) 175 kPa equals 25.38 psi. Assuming you're running a 3-bar map sensor and it's calibraed correctly, the numbers should be accurate.

The tuning tool can convert for you If you cick the blue car icon you will see a conversions tab there you can choose the to and from units from the drop down menu

Hmm, be careful of the kPa to bar conversion.

:bash: :bash: :bash:

If you want to fix it, you'll need to modify the file:
\Program Files\EFILive\V7\Configuration\unit_conversions.tx t

Change the line:
0072 = kPa bar * 100.0 0.0
to
0072 = kPa bar / 100.0 0.0

Sooo, 227 KPA that I am at equals 18.12 PSI????

227KPA
-102 KAP
/6.895
= 18.12 PSI????

I cannot believe I am really running that much boost on 93 octane??? I guess if I am, I am! Is this correct??

I'd double check the boost gauge-- 18psi on pump gas sounds unrealistic unless you have a super low compression ratio.

[nitrorocket]

This reading is off the efilive data log. I have 8:1 compression.

I need to get this thing back on a chassis dyno again for some REAL #'s!
