Can a DEQ dyno be repurposed?| Grassroots Motorsports forum |

We go to the Dyno a lot. It is cheap insurance to be able to make sure a car is safe to let out the door.

Boss man found a complete DEQ dyno for a price of taking 3 cars to our buddies shop. I have never been around one of them. I know Dynojet and that is all. It is small enough to be put into one of our outbuildings.

What we need is to be able to run a car on a load and check AFR's. HP and torque readouts would be cool but are secondary to our needs.

OK collective. Would we be able to coax a graph showing AFR over RPM with one of these? Would it be a project involving lots of soldering irons and arduinos?

You could get a controller from these guys.

I'm sure there are other options out there too.

Only if the dyno has a way of it's own to measure that- such as a sniffer sensor you put in the tailpipe as well as taking RPM somewhere on it's own (like on a spark wire).

That part really has little to do with the actual dyno but more with the accessories that it comes with.
