Hearing Lean Air Fuel Ratio
Weird thoughts! Delete this thread. Will check into this to confirm.

Kevin,
Why not just install an AF gage and be certain? -Bill p.s. install it on the passenger's side O2 sensor. As I understand the EG33's fuel rails, cylinder 5 will run lean first, as it it the last cylinder in the fuel path.

Speaking of insanity, I was surprised at how solid your XT6 looks. I guess we will see for certain once it is on the lift.

I just want to see how it runs alongside an SVX after this current modification. I am hoping it can beat a stock to mildly modified AWD autotranny SVX in the 1/4 (not all out top end). It has already ran a best of 16.4. Not to shabby for being 90hp less than an SVX. Yeah Tom! It was that camera phone pic I sent you of the Porsche GT3 that was in front of me. The showoff ripped it up leaving the gas station.

while I wouldn't say its a good idea to tune by ear, atleast on turbocharged cars its possible to troubleshoot by ear.
9:1 is super "watery" almost drowned sounding and will often start having rich missfire issues. 10:1 is merly watery 14.7:1 is very thin, highpitched with minimal power 13:1 is high and thin compared to the desired 11.5:1 many people tune turbocharged cars to. |

I can tell rich/lean conditions better with an EGT gauge than an actual rich/lean air/fuel ratio gauge. You may actually want to run leaner with higher octane or richer with lower octane, depending on what works for your ride.
