Once my MAF hits 11250 Hz fequency it levels off at 439.20 Flow gm/sec. However the table goes all the way up to 12000 Hz. The graph is an exponetial rise, not linear. So how can I complete the curve up to 12000Hz? Mighty Mouse was telling me that I can utlize my stock MAF and raise the limit to 12000 Hz toi handle my new procharger.

Thanks for your help guys,
Mike B.

 

Take the stock data (frequency vs flowrate) into excel or anyother spread sheet. Add an additional point of 12000Hz and 512 g (512 g is the max the computer will handle). Plot the data in a x-y graph or use one of the curve fit equations. If you use the x-y graph you can then do a curve fit to the data. You can try expontial or poly (of different orders). You want to check boxes that ask to print the equation and the "R" value. Whatever the curve fit type you want the "R" value to be closest to 1 (which means perfect fit). You then use the equation it spits out and plug back in the numbers to generate a new curve. Or you just get one of the many excel files built for this already or find someone with the correct info.
