Where do I get one and what will it take to install it in my 86?

 

got mine from
http://www.techedge.com.au/vehicle/wbo2/default.htm

They are a nice setup. Not too hard to install, just 7 wires which are pretty straight forward.

Cost is about 500 bean when all said and done.

Any questions email or PM me.

:cheers:

 

 

Is this a decent setup to tune off of?

 

:yesnod:

 

ski_dwn_it,

I have the techedge kit and I am waiting for my O2 sensor to show up from partsbin.com.

Did your kit come with any instructions for the installation? Mine didn't. I have the R232 option.

How did you run the O2 sensor wire through the firewall? Did you add a fuse or on/off switch to the power wires? Where did you wire the power to? Did you use alligator clips for temporary use?

I would like to know how you set yours up.

Thanks.

Mine came with a schematic. Here I will get it for you...



Just follow the instructions and wire it to the sensor. MAKE SURE you have the positive and negative right. I messed up and got them backwards and almost fried the whole unit. I was lucky and only had to replace a component or two.

I went through the firewall with the 7 or so wires right below/beside the brake booster. There was already a few wires going through there. I just opened it up a little more and used some of that corregated(sp) wire covering to make it look neat.

When I have my engine out this next month to put the 406 in. I am gonna redo all the wires and make it a little neater.

I have my unit tied into the wiper motor for power. Sees to be OK there. Any ignition activated hot 12v source will do.

I am gonna have someone help me out with installing another fuse pannel out under the hood. I have too many components *tied* into other things for my liking.

It will also make putting N02 in the car easier if I have an aux fuse panel.

Hope this help out. That schematic should make everything clear for you.

Be sure to put the sensor somewhere in one of the *main* pipes. Not in just one header pipe, or you will just be reading that one cylinder.

I have mine about 1 ft after the drivers side header. Just across from the H pipe, that way I kinda get a little feedback from the other side too.

The dispay is great. Here is a shot of it:



As stated before I have it tucked up under the dash infront of the stock tach. Since I have an aftermarket tach, I do not need to see the stock on. Plus its in the same like of sight with the tach so I can see both RPM and AF at the same glance. :cool:

I too have the rs232 option in mine. I am waiting for the software to be developed that will allow the AFR to be logged for a run.

For now, I have a solution to be able to go back and review the runs. Here it is:

Mount a vidoe recorder were you can video the tach and AF display at the same time. Then you can go back and replay the run and see EXACTLY what each RPM range's AFR is! :yesnod:

That is about the only way you can do it.

You will be amazed at how quick the AFR changes when say you *blip* the throttle. You can get you *pumpshot* exact and so on. There is no other way to get all that stuff straightened out, other than having one of these babies!

Good luck. Any other questions, just post. :cheers:

 

I wonder how I can adjust my pumpshot in a 94 Vette. I looked around in Tunercat and there's no table for adding fuel vs TPS.

:confused:

Thanks for your reply

Oh, if you look on the DIY-WB page there is software for laptop/ palm to record the AFRs

Super, will have to look it up. Do you mean on the DIY_australian or a different site. Can you post a link? Thanks

 

Nevermind. I downloaded it. Will have to go out later and see exactly how it works. best part is it is free. I figured it would be another 100 bucks or so! Thanks. I knew they were trying to develop the software, just have not been back to check to see the status! Thanks!

To all you others this is what the logger looks like:


Pretty sweet! Now I don't have to keep my eyes on the tach/AFR/road/chicks walking by :D

I should hope it would be free... That would take me all of 30 minutes to code! :lol:

 

ski,

Do you run yours on your car all of the time or just for tuning? Can the system be used continuous with normal car operation without shortening its life?

 

Well I have had this discussion before.

Here is my Theory and I think its pretty sound:

The sensor is about the only thing that could go bad in the system. The rest is all electronics. The sensors are made to be used in Honda something or other. So they definately are designed to last many thousands of mile of not forever.

Yes I have mine in my car all the time. I have not had any major problems. Just one connection came loose and that was my fault.

So my take on it is you can put it in and use it when you need it and forget about it when your not. I am always watching mine though. :D :cheers:

 

:yesnod:

I can't wait for my sensor to get here (maybe tomorrow).

Oh one last Q. I think I read somewhere that you want to mount the O2 sensor no closer than 15 degrees from the horizontal (something about condensation dripping on the ceramic). How did you mount yours? (In relation to a clock)
