I have set my AFR target to 15,6 while no boost and my mileage is not fantastic.

Anyone has any experience which AFR and ignition gives best mileage in our cars?

Yes, when I had stock ECU I had also AFR 14.7 while crusing...

But what is best for economy?

Now I have set AFR target to 14,7 and it looks like economy is better. I do not want to waste time to try different settings, maybe anyone has went thrue this before:D

I would really apreciate any help

Thanx man!

I really apreciate your response!

What about ignition setting? One of best tuners in Europe said that more than 40 degrees advance for cruising might be to much.

Does anyone know how does look like stock ignition map in our cars?

The stock timing map is very agressive at part throttle cruise. Can go as high as 50. I wish I could remember who/where, but someone has posted a timing map pulled from a stock ECU by some sort of scan tool.
