    AFR gauge

    Hello guys,

    is it worth to spend money on a AFR gauge to fine adjust the setup on a GP1300R with EFI Controller?

    what are the meanings?

    thanks

    I've got a wide band O2 sensor/gauge for the car readings, but to date I haven't found one person to give me AFR values for the EFI 1300....

    WB O2

    They are great tools, couldn't get my turbo cars tuned nearly as quickly without one. I'm not sure how well they work with 2-strokes. 2-strokes can loose a lot of the fresh air/fuel mix out of the exhaust port, this alters the reading of the WB. I have never tested a 2-stroke with WB02, but I have tested a supercharged V8 with a hot camshaft and we could not get accurate reading because some of the fresh charge was leaking out the exhaust valve. I know that some people have use WB02 on 2-strokes but there seems to be little information on this subject.

    I have always been told you can't use one on a 2 stroke

    I would expect the oil in the exhaust to be a big issue with keeping one accurate, most go with an exhaust temp guage instead.

    The water is the killer

    I just bought a LM-2 for the Doos, and will be testing it on a 2 stroke.

    Another project I never got around to. The bung in the exhaust is the same as the one in the 4-stroke Yamis, so you just need an adaptor from R&D or Riva & you're good to go on logging AFR.
