Dino is going to be sending me his DIY-WB o2 controller soon, so i'll finally have the oppurtunity to copy the PCB and build my own. (the guy wouldn't respond to my e-mails for buying a PCB from him so i'm just going to fabricate one off of Dino's after i build him his)
Bill has slowly been convincing me to get a Mega Squirt, or for those of you that don't know it's kind of like the 034 EIC but it's designed to controll any type of injector - high or low impedance. the only thing that i don't really like about it is the fact that it only really controlls 2 injectors via a batch firing mode, instead of sequentally.
i've been thinking... is it at all possible to link some sort of wide-band oxygen sensor (in this case, the DIY wide-band sensor) to an 034 EIC or a Mega Squirt to have it learn and perfectly tune the fuel curve in open loop by it's own? for example... i could set a goal like this:
RPM: 2000 4000 6000 8000 A/F: 12:1 12:1 11:1 11:1
or something like that... the DIY wide-band would output raw A/F readings to some type of injector controller (along with MAP data, RPM, IAT, and crap like that but i'll deal with that later), and the injector controller would say "ok, the A/F ratio is suppose to be 11:1 but i'm seeing 10:1, i'll narrow the injector pulsewidth by Xms every 500ms or something until it's on target. then i'll remember what the final pulsewidth should be at this paticular RPM for next time."
this seems like a really good idea to me in which the car would basically tune itself perfectly in open loop. any comments?
Well, the latest trend is toward direct port injection. That's neat stuff. Anyways, I believe deeply in the Megasquirt, as it is the best bang for the buck in fuel management. -=B-=
Dude, Boeing called. They want their wing back.

If you guys like I have no problem acting as a test subject....lol, might as well wait till I have mine up and running.... but I'm predicting awesome results.... the capabilities of the megasquirt are actually beyond what the EIC controller that most people use around here..... we shall see.
i have confirmed that the megasquirt does use input from a wide band signal its specifically setup for the DIY wb kit also...
i think that the mega squirt being setup like linux and open source where u can add anything u want is the best option...
Bill
maybe ill get one isntead of a smt6 anyone want to put mine together ??

You can have it cheap, fast or good. Pick any two.
If you want it cheap and fast, it's not going to be good. If you want it cheap and good, it's not going to be fast. If you want it good and fast, it's not going to be cheap.
ner hit me on aim and maybe we can work sumtin out =)
wanna make me a knock sensor add in that works with the mega jolt?

the o2 sensor it uses is a 28$ o2 froma vw or a honda and its oem equipment i wouldn't worry much about wearing out...
Bill
lookup lm-1 it has the part numbers for the vw 02 sensor
