Lean Burn

[Kracka]

I created this thread since its something I've been thinking about recently and it was being discussed in another thread. The above posts have been taken from the DD Civic thread in "Projects" section.

"Lean Burn" is a popular mod on the Evo's as it can be done very easily within the stock ECU. I figured it creates more heat therefore more wear on the engine (as backed up by Swanny), but am sure but how much. I used to run mine at ~15.6:1 (I've set many other local Evo's to the same) but am now back at 14.7:1 since installing my 850cc injectors; I know Scheides is at 16.0:1. I've been contemplating adding it back on my car to see if I can save a bit of gas. Swanny, could you please elaborate more on why you have chosen 15.5:1 and what made you come to that conclusion? Anyone else have any experience or insights?
