Wideband air/fuel ratio meters.

[Bill Dedman]

I just bought a F.A.S.T. wideband air/fuel ratio meter.

I plan to use it on my 360 Magnum, which is supercharged and has a SnowPerformance Boost Cooler water/alcohol injector system that is set to start spraying when the boost reaches 3.5 pounds.

On Snow's recommendation, I run windshield washer fluid (blue) in it. Supposedly, it's 50/50 water and alcohol. It sprays 4 oz. in 10 seconds.

This Boost Cooler seems to work as advertised, and I have had no problems with it, but I am curious as to whether running it into the intake airstream will affect the results of the air/fuel meter test.

Does anybody have any experience with this?

I was hoping somebody on this forum might have used one of these meters with water/alky injection and could tell me if it affects the readings.

I'll appreciate any advice or information about this.:read2:

i have a fast afr as well there are two settings one alcohol and one gas.

from what i understand the alky you spray is just to cool the intake charge the car doesnt run alcohol. you can just run it once without and once with it and see if there's a difference in afr's. on the gas setting of course.
