which afr meters you guys use? I did a search on here to see if this thread was started once but came up with nothing
I have older gills with long tails where abouts do you put the O2 bungs?

I use the F.A.S.T. EFI dual channel. Some guys use the innovate one.

which do you feel is the better one for the dollar?

I have never used the innovate one. The Fast one is available with 22ft long cables, which is nice in a boat, it datalogs also. A buddy and I went halves on it, we used it to tune our boats. Really a great tool to have.

zeke,is your exhaust a totally dry system?

no its not mike. ill try load a picture of them on my old motor

I use the Innovate MTX-L. Mounted the gauge in the boat and run it full time. Works great. USB connection for data logging. Real nice product.

how far above the water inlet should i have the bungs installed?

it doesn,t take a lot of moisture to ruin the 02 senser.

from what i recall mine mix pretty much right at the tail end of the riser
