<x-charset iso-8859-1> John, I see your point. It shouldn't be that hard to get rid of them if they're good. Lots of folks over at diy-efi.org are looking for solutions to monitor their A/F ratios for tuning. Yes, it is just a tool, and when used correctly, there's no substitute within most folk's finances. Many non-stock applications, I'm saying t3's as well as my headers-instead-of-exhaust-manifolds suburban, will require a heated 02 sensor to work correctly. 14.7 isn't a good A/F ratio for anything except textbooks, from what I've gathered. Most of the Chevy types are shooting for around 12.1 or so for highway cruise. Varies a lot on engine loading and immediate requirements, but that's why fuel injection can be so good. Remember, I get the list too, there's no need to reply to me directly as well. :-) Jake >-----Original Message----- >From: John Connolly >To: Kooser, Jacob >Cc: type3@vwtype3.org >Sent: 2/7/02 12:21 PM >Subject: Re: [T3] FW: needle mixture meter >I'd love to. but I have to have 20 made at a time, and the last set took >2 >years to sell them all (not a wise place to store $ if you want to stay >in >business).
