I have an Apexi Auto Timer with A/F ratio readings on my FD. I am experiencing these AF readings:
Aircond OFF and Headlights OFF: 14.2-14.6
Aircond ON and Headlights OFF: 14.8
Aircond ON and Headlights ON: 15.0
Are these readings normal? Why does the AF Ratio shows a leaner FD when Aircond and headlights are switched ON. Can some sifu give some insights on this.
Some extra info and findings: I realise my volt reading is around 11.x when I switch the aircond ON and headlights ON (volt readings flash) and 12.7 to 13.1 when they are both OFF (volt readings DON'T flash). 11.x is low, cos it is flashing. Has this any effect on the fuel pump? I understand that fuel pump operates at 12V? Could this be the cause of fluctuating A/F readings as I don't have a volt regulator or am I getting everything wrong here? Sifus sifus please help :)
Thanks.
