Hentai's ecu strategy ideas
Posted: Tue Aug 04, 2015 2:53 am
Just a list of things I have been thinking off
Note I am not of educated experince on the ICE
1) load on a motor also is effected by time
2) I think\believe that there needs to be atleast the density factor and a seperate IAT compenstation table
I have seen so many ecu show they have the IAT compenstation table for density factor but it ends of being hijacked for altering fueling based on temp instead of using it only for density
3) I've realized that one can go into boost at stoichmetric but most cheap ecu's can't deal wtih it properly, most VE based ecu model commanded fuel with load as map or connected to the VE load. Its very annoying. As well as modeling the correction ign advance curve.
4) VE based ecu's and MAF based really require proper injector modeling. SD based seems to require accurate modeling of even more factors, Look at VW and their removal of MAF's now, tons of stuff is modeled in the ecu like egt, turbo speed, etc
5) torque based strategy with DBW implementation. This would require probably a good bit of work to implement but I could see it as a way to control the output better and usage for other things like power limiting\traction\etc
6) I somewhat question why you would have mutiple ve maps if ve is suppose be the engine's ability to breath. In the end I understand you can't model everything.
I have other ideas that eventually will come back into my head.
Most of my expereince is from a driveability standpoint and not much motorsports
