Ok'' i jsut got a ross tech... what are the formaulas for fininding HP and Torque. And boost and PSI ??? in Excel.... i have the raw data but dont really know how to decifer it...
Thanks
Mike

Well there used to be a really good post here by Wolfsburg2 but it looks to have been deleted. Maybe he will chime in with a copy.... Anybody else save that post?

Here's a quick tutorial I put together for Block 120 and includes the formulas:-
lbft = Nm x 0.738
hp = rpm x lbft/5252

Boost Guage PSI = (mbar-1013.25)/1000*14.50377
[where mbar is the boost from your block 115, 118,119 etc]

Really rough mbar to psi boost calculation
((mbar - 1000) * .0145) = psi
The -1000 is to try to compensate for atmospheric pressure. Without it you will think you are running up to and over 25psi

. 1000 mbar = 1 bar = 1 atmosphere at sea level. If you want an ACCURATE measurement you will need a barometer on the outside of your vehicle to measure actual atmospheric pressure.

Make sure to log a single measuring block at a time because more blocks will give you less "resolution" so to say - It'll lower your sampling rate per block...

i agree,when i do 1 block i get roughly 42 measurements but when i log 2 blocks i only get maybe 20
