I use both types, only because the hole in the dash is there for the old analog gauge. the new style with the lights is the way to fly.mount it high and you can see it from the stands. Its hard for a driver to read a needle, the light, is nice.

If you want the ultimate setup look at tuneyourengine.com We bought 3 of these and have one hooked on our chassis dyno. They are slick. You can record 90 minute's of track time and down load the info to your computer to give you the air/fuel ratio. Well worth the money. In a few years they will become standard equipment.

Both of these items look good, but how do they fare with the typical Leaded racing fuel? The one from tuneyourengine warns that the sensor be destroyed in a few minutes with leaded fuel. What has your practical experience been?

I worked with a few different air/fuel manufacturer's and they said the life will be shorter but a few minutes is way off. I will get ahold of tuneyourengine and see where they are comming from. We have logged over 20 hours on one of the unit's and all is fine.

Sounds good. I believe I read that "minutes" info from an owner's manual that they offer for download on their site. If you do talk to them, ask(or maybe you know) what would the failure mode be for lead poisoning? Would it just die, or would it gradually go off the deep end with regards to accurate readings? I plan on putting some kind of A/F meter in our car this year. Accurate and repeatable readings over time are a "must have" requirement. Any info you could share would be appreciated.
