measured air flow
« on: July 13, 2014, 02:42:08 PM »

i have measured the air flow of my cylinder head plus intake runners using a super flow 600 flow bench in 0.050" increments until flow maxes out, about 0.4" lift.
I have detailed cam lift vs angle in 5 degree increments.  Head cc (44), compression ratio (10.5:1) as well as dynamic cr (7.8:1).
Is there a way to build an accurate map from this information?

Assuming you have the MAF and WAR Chip. Start with the provided base tunes there and work from that. The most important thing for the ECU is that the tune is calibrated to match the MAF and injector size. Everything else the ECU can take care of in terms of flow. The fuel maps are correction tables to "correct" the theoretical amount of fuel calculated by the ECU based on load.

Timing is another thing, but won't be too hard to dial in. The tunes provided will be a decent starting point.
