Factory Apexi PFC maps?

[Peter Wilson]

Hi guys,

Can anyone assist with factory ignition and fuel maps for the R33 GTS25T PFC?

Any format is OK - I am just putting them into Excel to compare before and after maps to see what my tuner actually did...

Thanks, Peter.

I dont have the factory ones anymore but you will find they won't alter the ignition maps, just the fuel maps as they tend to run rich

Chasing it up for you...

anybody care to explain how to read it. Is that RPM on the vertical axis? not sure how it works. I guess this is BTDC ign at all diff load points. Is this how the PFC defines its load poits. 0-800 and 0 to 21213??

Yes, more input please!!

It should be easily converted to an intelligible 3D graph, but the scales and parameters are not clear.

cheers

Its quite easy to read. The horizontal scale is the rpm points and the vertical scale is the load points

[benl1981]

times by 10 on the horizontal is it??

[Dale FZ1]

cheers, makes more sense now.

I assume that the load points are arbitrarily chosen by the software writer to give adequate resolution? ie. don't be worried so much about the absolute numbers, just the variation between them in the scale?
