OK, I have been tinkering with the new-to-me AFM on my 1911cc engine all weekend. I have adjusted the spring about 20 teeth CCW to get to this point.
I have been using an A/F sensor and gauge. can someone tell me, or direct me to a chart/table of what A/F I should be shooting for on my daily driver. The last adjustment of the CO screw has left me here: I have always had a strange idle situation, so lets ignore that for now. any normal adjustments to reduce the idle at normal operating temp eventually stall the car. A problem for another post. (IMG:style_emoticons/default/blink.gif) the idle is high.... at 1200 the A/F is a smooth 12.2. I found a long hill and drove up it at about 3800 rpm and the A/F was 12.5. thoughts? |

I just saw an ad for an AFR from Innovate that monitors 2 sensors. They say left and right banks on a V8 engine may run different numbers. Does anyone have experience/opinions on this? Could this be helpful?

Could this be helpful? I have one of these with my 911 engine headers. Info is very helpful tuning carbs. Do not cut the harness to fit your application. |
