Re: Fixed point mathematics
We have discussed this at some length previously... I understand Hass's comments. It makes sense that a flat VE will not be hurt by taking multiply map out of the fuel equation and maybe even help. What I still do not get is the thought that a VE limit is a problem. It really depends, as I see it, ...

Re: Fixed point mathematics
yeah, i think that's my main issue - the individual VE entries in the table shouldn't be defining the resolution. it makes for a pretty big tuning mess unless you have a flatter VE table (which multiply map does help somewhat). I do like the flexibility of 3 VE tables, multiply, and additive - i was...

Re: Fixed point mathematics
I think there are a few ways to use 16 bit VE values - you could either have a whole number in the VE table, and divide it by X to get the "real" VE, or you could simply add decimal places. I don't know if that much resolution is truely neccesary though - highly accurate injector PW contro...
