Frenchmeister said:Nicholass,
How ,how have you achieved your AFR readings, stoitch is 14.7 I believe, running 17ish when cruising is pretty lean
This question was just asked by Frenchmeister in another topic. I started a new thread so I don't ruin the original post.
Frenchmeister you are correct. Most cars run (or should run) 14.7.1 AFR which is known as perfect Air Fuel mixture. If you look into the manufacturer software, you will see on cruise Porsche have set my engine to run a LOT leaner than the figures I am running at cruise.
This is the original fuel map by Porsche (Bosch) for 911 Carrera 2S 3.8 Litre 355hp
