Lean AFR during cold start
Curious about what you guys get as AFR during start with cold engine
tuned many cars remotely and locally and always see around 15.44 target afr during cold start.. then slowly going to stoich as it warms up Still haven't figured out how to hijack this leaning as it seems to me hard coded into ecu and/or not defined in ecutek tunes Why do these cars lean out during start? I thought OEMs usually made the cold start rich to provide a more stable idle |
