Correct Air Fuel Ratio for Falcons
G'day fellas, I've just been reading my Max Ellery EA-ED manual...
The Fuel Mixture is adjusted at 14.7:1 and ideally maintained at that by the ECM.
On a the recent SA dyno day i discovered my ratio was actually 11.5:1! The guys at blackwood dyno used an addon fuel regulator to change it to about 12.5 and I gained about 4rwkw. they were trying to sell me this fuel regulator for $360, but im not so keen. I was wondering if there actually is something wrong with one of the ECU's sensors, as the mix is out (according to my book anyway) by 25%. The Intake is stock, with regular paper element, perhaps upgrading this would be beneficial?
