Meth with nitrous tuning What's a good air to fuel ratio on juice with 100%. Meth as a fuel supply? I'm on a 150 wet shot and have a 225ml/min meth nozzle. I can adjust the fuel pill to help lean out the mixture but I have not a clue what the AFR is supposed to be. Right now its running about 10.8-11.0 Spraying. Seems to pull ok but I know with methanol you can get more aggressive with the tune. Any help is appreciated
Dont Tune in AFR, Tune using Lambda and your plugs...
start around .83 Lambda to .85 Lambda to start, and then fine tune by the plugs...
theres no way of knowing your exact mixture of Petrol to Meth, so you cant go by AFR
a 150 shot you should be on a #6 or #7 Heat range plug
and a non protruded tip Nitrous style plug

Whether he uses lambda or not 10.8-11.0 is too rich.
Tune off the plugs first then note what your wide band reads when the plugs look the way they should (little to no fuel ring and proper heat on the strap). Most have found their tune-ups start to clean up around 12.4-12.6 afr and a good clean plug and tune-up will 9/10 be in the 12.7-13.2 range.

Yes I'm using Ngk br6ef plugs.
I figured 10.8-11 was too rich but I was just wondering cause alcohol is a bit different.
I'm gonna lean her out some to get it closer and keep an eye on the plugs.
You guys have a good write up on how to read plugs?

PM Carter01, Camscam, or ATVracr and ask them for some pictures of their plugs so you can see what rich, kinda rich, looks good, looks perfect, kinda lean, lean, under timed, over timed and what the plug looks like with perfect timing.
