A/F gauge
hello im running a carbed 400 sbc and i figure i should use an air fuel ratio gauge for safety and tuning.do i need an o2 sensor on both sides just incase one bank isnt running the same somehow?because i know hondas only have one pipe out so theres no need for more than one,so what do i do here just use one wideband and thats it?

Check this out mine work well but I replace R1 with a 5k pot and make sure to tune them to 0-1V

Re: A/F gauge
exactly.. those autometer ones that run off the O2 sensor dont really tell you whats going on with the car.
you need a Wide Band O2 sensor from Innovative, but i wouldnt leave it plugged in all the time, just for tuning purposes, then remove it. Those sensors are not cheap.
the whole system is about 375-400$

Re: A/F gauge
I'm using AEM UEGO Wideband sensor and leave it plugged in all the time. It was a great aid in dialing in a Q-Jet I had rebuilt. Here is a link http://www.aemelectronics.com/wideba...fuel-gauge-25/ Wideband is the way to go.
