honda doesnt tune your ecu to run at lambda from the factory to make better gas mileage...
plus engine management will make every bolt-on mod you buy give you more horsepower when you tune your engine... crome makes most bolt on mods and turbos as easy as changing some settings...
when tuning though, data aquisition and a dyno will make your life much easier... try an ostrich realtime emulator... it allows you to hook a laptop to your ecu and collect data... then you can instantly change and upload your new settings to your ecu on the fly while you drive... i have even heard of some software that gathers your data and projects where you could make more horsepower and changes your program.. this is the 'autotune'
1. It costs more than $20 to tune. You have to factor in a chip burner, wideband, laptop, chips, rom editor (if applicable).
2. Stoich A/F is 14.7:1. You only want 14.7:1 at idle.
3. Lambda is the wideband voltage for any given a/f ratio.
4. You must have datalogging to tune. Blindly changing fuel and ignition values is retarded and will cause more harm than good.
5. An ostrich doesn't datalog. It real-time emulates.
6. Crome pro has autotune, but it changes the fuel values to meet target lambda, which is set by the user.
7. To my knowledge, F22 bin files aren't even supported in Crome, so the post is irrelevant anyway.
