Air fuel meter
Hey guys, I have a FAST Air fuel meter, but have no way to reference the playback with RPM or time in the run. I don't have any other type of data logging system. What are you guys using to track and review this info? I have used the one I have and just used best guess to tune it in the past. But would like to see the A/F at rpm if possible.

No experience with this unit myself. A brief look at the product description makes it seem it is capable of outputting a signal to datalogging devices. Seems like your overall plans/goals would dictate a path forward on this. Lots of options. Most of the aftermarket engine controllers are capable of datalogging now and really more cost effective than standalone datalog systems. Hopefully someone experienced with this unit will have an easy option to offer.

I use a FAST unit mounted on my dash and have a GoPro mounted so all the gauges are visible in the frame. I start logging data just before I get to the line and stop logging after the stripe. It's been very easy to tune watching the data log replay and video from the run. Here is a run, start at the 3 min mark.

Nice run. Any idea on what the Track altitude is on that run?

The car was running 13.0-13.1 AFR during that run. Need to increase all jet sizes up by one size to bring it down to 12.8-12.9 where it runs the best.

My LM1 had an input for an LM3 that would do rpm(I had to use a variable resistor to get it correct), G force and vacuum so I could plot it all out and log. It might had had one more channel also.
