Pop mailed this too me and I have been playing with it this after noon. So far I am impressed.

You know what this works well enough that I think its worth buying guys.....

I'm bumping this because I think its probably the best SI engine tuning tool I have seen and used in the past 10 years......

I've had a couple of these for years and they are handy for dialing in the fuel mixture.  However the ones I have can't be used with the engine under load, like on a dyno or driving down the road, or they will blow apart  !  My dad told me once that the hot accessory for cool cars way back when(like model T hot rods with no hoods) were sparkplugs made with glass bodys instead of porcelain so it looked cool when driving at night  !  He couldn't recall any drawback to those plugs but remembers that it seemed a short lived fad.                          Leland

Been one in the workshop for 30 years, maybe more. Must have used it about 4 times.

I'd love to have aset of those glass plugs so I could watch the engine under load but this is good enough for me!

Haven't tried it, but I suspect that I would prefer a wideband O2 sensor.

Haven't tried a wide band 02 sensor probably very informative but I don;t have that kindof money and its not something I can carry on a bike with some different plugs and jets.
I can look at a gasoline flame and tell rich from lean just by the colour. I can't tell you numbers but I know what it looks like. Now give me a window into an engine and Mr. I can start to make some informed choices before I change heat ranges and such
