I wish I had a flow bench to test this on but- Does that calculate VE, based on the MAF? How is that accurate- like the MAF could be from a 300 ZX. VE won't change from that????Q45tech wrote:Simple calibrate the MAF to grams per second on a flow bench, then divide by 4 cylinders and rpm..................how many grams flow into cylinder per revolution vs displacement = VE.
