Anyone use F.A.S.T. air/fuel ratio meter?

Just ordered this from Summit, going to give it a shot.

It has a one year warranty in writing....which looks like more than most.

The thing I like about it is, it doesn't require a laptop be carried around, it data logs right on the screen.

Anybody use it before? Any luck?

I have a couple cars I have tuned have them but both have the optional rpm input which I really like. One is close to 2 yrs old now with 0 trouble.

Good to hear, thanks. Just hoping the thing works as advertised.

Hi
I have it , for a race car you have to use the collector extensions to make it read right , other wize it worked good.

Mine is 2 years old and the only thing I noticed was the o2's got a little lazy this spring so I replaced them right before Pinks in Belle Rose. Mine stays in my car all the time street or strip.

I've got this unit on my Duster. Haven't had a chance to use it much since I've only made 3 test passes since I installed it. I don't have the optional rpm software and I can already see that for a race car its a must. Otherwise you can't tell much about anything. It plays back in real time on the screen so its hard to get a good feel for the data. And with open headers it reads 0 at idle. It doesn't start to read anything until you get it under a load.

Thanks for the replies, appreciate that. Can't find anything negative on it, no buyer's remorse here.

I will be using it with an exhaust and mufflers mostly, which should hopefully help it work correctly.

Question: will using it with a pan evac mess it up?
No problem taking the evac hoses off with it, but I don't know whether to do that or just leave it alone.
