A goPro pointed at the gauges, about as low cost as it gets. After that low cost is really not in the equation for data logging.

I did this for years....Tough to read the gauges with it as the car and gauges have some vibration. You would have to put the camera rigth up to them, and even then, you may miss a spike or other quick change.... https://www.youtube.com/watch?v=Znuo3jMUXTkThe next jump up, and one I have adopted is the Holley Stand Alone dash.....Not as easy to setup as I thought, but you can expand it to read anything you want to monitor. So far I like it.

I think the goPro is very usefule and cheap. Guess it depends on how your gauges are arranged. You kniow where the needles should be whne things are going well. In my case a GoPro worled well, but I also have a delay box to show RPM and a racepak but at one point the GoPro was it. https://www.youtube.com/watch?v=73PrnH45uec&t=3s

I used an Innovate SSI-4 successfully for a while. The bad thing is you have to have the laptop in the car to do the "logging", but it's probably the cheapest way into it all. https://www.innovatemotorsports.com/ssi-4-plus-4-channel-sensor-interface.htmlThis alone though really only gets you very simple inputs that maybe you already have like RPM, Trans brake release, or temps (if you're running electric sensors). In the end it just depends what you're trying to read. Every sensor costs money, some more than others, some more valuable than others. Are you trying to tune the engine, tune the suspension, etc... they all need different sensors, and will have different costs to get there in the end. I personally think RPM, O2, Driveshaft Speed, and Acceleration (g-force) are probably the 4 most useful.

This video is with an iPhone. I have purchased a used GoPro 7 because it has the stabilization. Hopefully I can button up the new engine in the next week and be able to give it a try. https://youtu.be/CXS3ksWzN-U

I have been wanting a low cost data logger myself, and have been using a camera aimed at my AFR, Tach, and other gauges with mixed results. I'm not as serious racer as you guys running every weekend, so I'm making the camera thing work.

We've been using Low Doller Motorsport sensors on our racepak, happy with them so far. They are a way cheaper alternative to the plug 'n play branded v-net sensor but have to be used via a universal serial module (USM). Some low doller sensors may need the calibration table inputting but as far as I can tell, the majority are like for like. One advantage of data logging over a go-pro is you can overlay runs and see if your adjustment / tweak, has made any improvement to that particular parameter during the next pass and if it has helped 60ft / et / mph etc. I would keep an eye out on the various racing websites as a lot of Data logging stuff comes up for sale and can be had cheaper than new but there's obviously the S/H caveat. I've found support for Racepak real good here in England, appears to be the most popular logging system used and the various websites / forums are pretty good too for help and info.

In my experience you can datalog a voltage relatively inexpensively. The cost goes up if you require interactive software to interpret the results. Recording a 0-5v datalog can be done on a multimeter. Many of them have bluetooth capabilities so the data can be exported and manipulated in excel.

I use a gopro Hero. (One of the older ones that look like a cube.) I put it in the middle of the cross bar on cage hoop. It shows gages good enough to know what is going on. It actually saved me years ago when I realized my car was losing oil pressure on launch with the wheelies. As far as the LM2 that was mentioned, I have one, but IMO they are a flakey piece of junk sometimes. I have never been able to get mine to work half the time, and never did get the RPM to record. If you get a good one you are lucky. I sure wasn't. I have been considering dropping the cash on a Racepak Sportsman. Need to log RPM and Wheel speed to get my suspension sorted out.

I will say the lower dollar you try to go, the more tech savvy you need to be. LOL
Yep, that is how I have full sequential EFI and can data log anything I want for less than the cost of some dataloggers. Had to do my research though! lol

GoPro isn't going to give you driveshaft speed, input shaft RPM in a stick car, Gs, or a bunch of other stuff, or be able to pick up glitches that a good logger will.
I've heard guys complain about the cost, until they get it in the car. Then it's worth every penny. How much money you spend running up and down the track trying to figure stuff out?
If the results don't match the theory, change the theory.

Not low cost but I run Racepak with numerous sensors. It can be worth every penny for many different reasons. One I can think of one of my buddies cars had an issue where the car would slow down .3-.4 periodically. I noticed one time looking at his nitrous pressures it was always off with one particular bottle. Tagged the bottle and set it off to the side. The problem went away.

If you buy second hand, just make sure you are not going to have to pay for software updates etc to use it. I bought a system many years ago, the Software update was worth half a new unit.
I am going to go down the ECU route for my own project. It will do the data logging I need, plus I can look at controlling the ignition etc with it.

It's amazing how fast you can pick up on things, and improve your race program with a data logger. There is no guessing, did it do this, or that? It's proved it's worth for a clutch car.
