I am very happy it's solved. We need some strong fn2!

Don't know but this was what I had. The car was lean and 100 duty cycle. After changing the sensor the car was realy rich in reality.

your 02 sensor is dead and went to sensor heaven.
If you add fuel and it's still reads lean this is the cause.

you should buy a etune from Vituned or other etuner.

the car is running rich. Have you changed the intake or exhaust?

You haven't answered my question as to narrowing down the problem. I've got a forced induction vehicle which does not exhibit this problem on either Race or AFM calibrations, so I can assure you that it does not affect 100% of vehicles. You may have guessed that our development effort is concentrat...

part throtle very good. no problems.
WOT 2600rpm to 3200 lean.
WOT rrom 5600 to the cut rich.
Not dangerous but can be tuned with litle work.

No, that is not a fn2 cal, it's a civic si from usa cal. Don't use it.
Use the groupn cal.

You have not said, but I assume that you were using the race calibration. We do not recommend using race calibrations in street cars. I think you should review this movie: http://www.youtube.com/watch?v=E2fLKOtchso So, what are the problems that can be caused by running a MAP (race) tune on street ...

any news?

have you try to disconect the battery for 30m ? (I know this work in other cars like peugeot's)
But probably only with honda tools.

Any news paul?

Hi hondata,
Only to tell that I am now using the Vtc tables upon decel fuel cut and the car is much smother on lower gears off the throttle. Getting of the throttle and not going immediately to 0 degree cam angle is much nicer.
This new beta is great for the fn2.

I can't find that table also!

the fuel overrun cut delay it's on the Fn2 calibrations for some time.
