Anybody try one of these? I wonder if this is better then the normal A/F gauge people complain about.

 

Well i would imagine from the price and what that says that it is better. Myself i would just stick to an AFR on the rear bank and a EGT on the front bank. Cant go wrong there.

 

I'm starting to perfer the digital AF gauges rather than the christmas light ones....even being that they are a tad slower in reaction I think straight voltage readinds are much more reliable and easy to understand/use rather than trying to match the lights with the equivalent voltage readings.

 

Yeah that is a tad annoying unless you have all the lights memorized.

 

You guys should check out the dynotune.org digital a/f and egt gauges. They give the most accurate reading down to the .01 for actual oxygen/airfuel reading and to the 1 degree point for the egt. The only downside is there is no peak memory to get after a wot run. The a/f gauge does give an exact reading when wot, that can be converted to an actual ratio ie 12:1,11.5:1 or the other direction leaner. The egt probe responds just as fast, check them out, they may be able to add a peak/memory feature. These keyfob size readouts are much more concealable than bulky round gauges, if of course you don't need/want the bling of those big A pillar mounts.
