I finally got around to getting my DIY-WB running yesterday. Went through the checkout procedure and all looks OK. Now I need to mount the sensor. I ran across a picture of a tail pipe mount yesterday, but now that I want to show it to my brother I can't find it. Anyone got a link to that picture?

Also, a while ago I ran across a page discussing modifications to the diy-wb circuit to improve its accuracy, but can't find that either now that i want it.

I got my emissions inspection notice for my 928/Vortech/749 track car in the mail Saturday, so it's time to get serious about cleaning it up! (not to mention the fact that we're back on the track in about 4 weeks!!)

Thanks,

 

Heres one taken from the dummys guide to building the diy-wb faq.

 

Might be easier to just weld a small set of vice grips instead of making that pinch clamp.

I'd suggest a few more inches of tubing past the sensor, ~5" seems OK. You also want it to extend into the pipe by about %-6 inches.
