$OE wideband hack?

[babywag]

Anybody ever tried a hack to the $OE code to strickly use a wideband?
Mostly curiosity, but it would be better than NB.

as in, closed loop wideband control?

it's certainly doable.

Yeah, ditch the NB sensor and just use a WB.
Like the aftermarket systems that are on the scene now.

doesn't take a whole lot of code to impliment it. a couple hundred bytes used in place of the existing narrowband stuff could use the BLM and INT identically to how it does now. could either emulate the existing method of sending slightly rich and slightly lean constantly to average a target AFR, or just direct to a target AFR and don't attempt to swing around it.

I dare you!

i'm doing it eventually for nAst1.... i think i'll be implimenting wastegate control first though, since 3BAR MAP is already done.
