by a friend I was told lately that monitoring an exhaust temp gauge can have a more accurate reading than the A/F gauge to see if you're rich or lean, true or false? I'm thinking about putting both in, I already had a 2nd O2 Sensor boss welded on the pipe, now waiting for gauge

Re: A/F gauge vs. Exhaust temp (G60ING)

I thought it would be a good idea too, I mean it's known that A/F meters are not accurate, they're just used to warn you when ur too lean or whatever.

Re: A/F gauge vs. Exhaust temp (G60ING)

Frank's right, they should be used together. AFR guages are notoriously innacurate when EGTs rise, because the o2 sensor can't deal with the heat. An EGT guage is a great tool, but can be tricky to use because you can have high egts due to running to lean, or not enough timing... it's not always one cause. Having an AFR for some validation can be of tremendous help. Get em both!
