SUPRAGTE Forums Junkie Location: North Sydney Registered: May 2002	Re: 1JZ: AF ratios too rich Mon, 30 September 2002 02:27 Had you warmed up the car sufficiently before your run? If the coolant temp was reading anything more than 6-8 deg c below normal operating temp the car will automatically run richer as the car is still "warming up". That may have been an issue or not. Also if you were warming it up and maybe to much heat soak could have been an issue. Your intake temp sensor may have hit like 50+ degC while you were idling and this also will make the ecu inturn make the engine run richer. From my experience about 12.4>12.5 is optimum for turbo cars, well thatS what i run on full sing. The richening early on in your graph will be where your turbo is trying to spool. Extra fuel is added which makes the exhaust gases denser and this makes your exhaust turbine spool up much faster. I've got up to 18% extra fuel to help spool up in part of my mapping curve. That richness isn't anything to worry about, its a good thing. Your full load af ratios are important though. [Report message to a moderator]
