ive been looking through old threads for a couple of min for the schematics for a wb o2 does anyone have a quick link handy or know the title of a thread they r in by chance?? and how much am i looking at to build one? thanks i just heard its the easiest and best way to dial in afr in wot thanks

and if anyone knows where to find a dissasmbley of a 8746 code or a windows not dos based program for dissambly/ reasembly plus table locations for stuff id appreciate that too.

The only expensive part is the sensor. It can be tricky finding the harness end connector for it.

would something like this work or does it have to be either an oem or ntx ??

 

I just bought a LC-1 wideband o2 off craig (www.moates.net) for $199, and you should too.

After reading the manual on Innovate's website, I was hooked!

This thing is fully programmable, comes with all cables. It has two outputs. One which can go into your narrowband o2 lead, and the ECM will think its running a narrowband.

The other into whatever pin your wb-02 hack uses, and can record true AFR in the "target AFR" field.

I can't wait to experiment and see how it reacts as a narrowband signal too. I'm curious if its accuracy is good enough to get the ecm to toggle a true AFR throughout idle and cruise.

I've been DIY prom tuning for about 5 years now, and I've learned a lot of stuff. But I'm really excited now that I'm collecting some "real tools".

I have been using the LM-1 from Innovate for a couple of years in NB simulate mode in a few different vehicles. While it maintains the stoich AFR pretty well in idle or otherwise in closed loop, it is not capable of accurately simulating a NB O2 closely enough to tune PID gains, thresholds, or the like. It keeps the ECM happy, but that is about it. HTH

 

thats not too bad a price probably alot better than the o2 in the civics but im gonna call around to some junk yard and see if they have any of the civic there if so i can get it for a few bucks but i dunno yet. if that falls through i will proabably wait and get that one from moates after i start tunning some.

 

My thoughts were using the narrowband corrections just for idle + cruise.

The only problem is, (and Bruce can correct me if I'm wrong), is I think on $58 mask AE and PE uses "learned" corrections from the 02 and isn't a true "open-loop" mode. That puts a damper on things and may force me to stay open loop anyway.

I am running an innovate LC-1 too and I love it.

Justlearning: Keep in mind, there is ALOT more to a WB setup than just the sensor. The sensor needs a controler to work. The LC-1 has one built in to the harness. The DIY WB uses a more expensive O2 sensor, while the LC-1 or zietronix setups use a cheaper (60$) bosch sensor.

 

yeah i know that but it seems all the other parts are all nickle and dime parts w/ a lil bit of solder and one company thats linked in that thread even has a whole kit....the sensor would be the only part to really hurt the pocket. the board looks alot more complecated than anything i have ever done but i can solder decent and i dont think there is much more to it other than tryin to read the schematic...i just build the serial aldl cable and that was one of the first things ive built form a schematic but it wasnt that bad although i havent tested it yet...the solder is sloppy but none is touching and all have good connections. it also seems like that board in the pics has alot more space to work. the schematic is alot larger w/ many more pieces but if i take my time i think i can do it.

thats only if i can find the wb sensor at a very good price like outta a yard or somethin would i try to do it if not i wouldnt take the chance on a part that costs over 100 bucks new i would just buy the wb u all r talkin about. thanks

Oh and BBmonte any idea on that pm i sent u about how many sanding rolls im gonna need for the heads?? as i said ive never done it b4 and dont wanna waste money and buy twice as many as i need. thanks if u could help id appreciate it
