i have the auto meter air fuel gauge just be cause i got a good deal on it at the time. but i was wondering which one everyone would recommend for acuracy? Greedy? Apexi? thanx

 

The Greedy ones are really nice, and come with a 4 wire O2 sensor, but are around $300 The Haltuner ones are nice as well. Both are availible at rx7.com

 

i have both the autometer and the haltuner w/ 4 wire haltech o2 sensor. they both read exactly the same. the autometer did not read as good as it does now. i think its something to do with the fact its a 4 wire o2.

 

I have the autometer hooked up to my Bosch 1 wire O2 sensor. Works good. I think if I had a better O2 sensor (one with more than 1 wire) it would work better.
