RPM limits - how to add function

merror · Post by **merror** » Thu Aug 14, 2008 9:00 am

Hello

Can somebody tell me how to add this function i tuner pro ??

The formula to arrive at the value in rotations is approximately RPM = 9650000/(b1 * 2^b2), where b1 is the first byte (B2h or AAh) and b2 as the byte (03h in both). The cut rotations would be ~6800rpm and 7100rpm.

stop fuel = b1 (B43D) , b2 (B43E)
start fuel = b1 (B445) , b2 (B446)

Best Regards
Lucas

Using the formula 9650000/(X*(Y*Z)) sort of works. You need to have B1 assigned as the item. X needs to be 'Argument 0' with the argument type 'This Items Raw data'.

Y and Z need to be 'Argument 1' and 'Argument 2' respectively with the argument type 'Raw Data at Address', the address needs to be that of B2.

I say 'sort of works' because it does rpm range limit you.

If you look at the TunerPro help file you will find an explanation of how to do this; go to the 'XDF Constant Items' page (under the 'Editing Bin Definitions' section), scroll down and click the 'Click here for information on the conversion tab' link.
