Running lean..
I was thinking about how you could tune the AFR of cars other than hondas in order to get better mileage. Is the only thing that would prevent running lean would be the risk of misfiring and knocking/pinging? If I was able to avoid these conditions, would running lean be an issue on cars not designed for lean burn?
What exactly besides the "swirl" the honda introduces into the cylinder would make running lean a bad idea? I figure the swirl idea could be introduced into vehicles with 4 valves by having just one valve open on one side which is what Vtec-E does. Correct?
