I have a Wideband Air fuel gage and have been adjusting my MPS. When I was tuning injected motorcycles I was shooting for ~12.7:1. What numbers do I want to shoot for in a 2.0L FI D-Jet runing regular fuel.
I was thinking that I want to keep the numbers setween 12:1 and 13.5:1. I have hear that >14:1 is to lean. |

Only worry about the numbers under load, accelerating and cruising. Forget about the numbers the rest of the time and idle can be a bit lean. |
