after using the moates ostrich, APU1 and willem programmer, i found that the narrow band 02 sensor is a piece of junk tuning wise. I would like to upgrade to using a wideband, but am put off by the $300+ cost. Cant i just get a heated unit and stick it a foot or two into the tailpipe like on a stick or somthing? I have a very sensitive analog voltmeter with a playback function, and tunerpro supposedly can connect to the wideband directly for datalogging purposes with some cables. Has anyone dont this? I searched this site, and found out a lot about how 02 sensors work with the megasquirt system, but even searching google the talk seems to revolve around spending hundreds on diy kits and such. I really dont need to see a display of the actual a/f ratio as its the voltage that matters, right? After spending 500$ so far, i really would like to get out of this one on the low low and a heated wb sensor is like 80 bucks.


sorry if this is the wrong category i'm new to tuning

 

WB on a stick isn't reliable unless you have some serious exhaust flow moving out the pipe.. at idle you will most likely get false readings.. get the innovate LC-1.. can be had for less than $200.. and I believe give you a 10-20v output so you can easily read realtime A/F on a DVM
