Message And Devin says :
"So lets say for example purposes that you double the size of the injector i.e. 740ccs. That means at the same pulsewidths, the 740cc injectors will dump twice as much fuel as the stock 370ccs [...] So if we double the size of the injectors then we must cut the pulsewidth in half"

So he means that the function is linear (but you have to modify the latency parameters).

But when I searched for K-values for 555, 720 and 740cc, I found values that are not a perfect ratio of the stock 370cc K. Especially in my Zemulator where Ash hard-coded K-values for 370, 555 and 720 cc injectors.

So who's right ?

And subsidiary question : if the function is linear, does it mean I can use a 370cc/single pop EPROM (AshSpec, JWT...) with 740cc/dual pop ?
