OK, I think i am properly confused!
Any recommendations for a lower priced scan tool that will show me live data?
It's easy to get caught up in the tools that are available. Bells, whistles, etc. And if you're like me, easy to nerd out on all the data we can grab. All goo and fun... until you see the price tag.
I have, and have been through, my share of scan tools. For me, the dust settled on TopDon and Innova. But honestly, 90% of those decisions came down to personal preference, not so much tool capability because they can all do the job once you match up what you need and consider the correct within a brand. besides, it's no secret that many of the Android based scan tools out there share a lot of the software, and as I understand it, they all use the same API to access the hardware.
But you asked... "Any recommendations for a lower priced scan tool that will show me live data?"
Not sure if it was already suggested, but take a look at the OBDlink MX+. It's a solid OBD2 dongle, but more more importantly, the accompanying ODDwiz software is great! The only downside is, it's Windows based. So you'll need a laptop/PC. But that's why this software is so good. It's not limited by Android capabilities, which is what most scan tools run on. Windows allows much greater software and feature functionality. Good thing is, the MX+ has pretty good range, so you're necessarily stuck in the garage. I've used mine with the software on a PC in a second story office half way across our 4000 SF house. No problem with that range. Gathering, watching, recording live data, is a breeze and very customizable. I run it on a 32" monitor because you can get so much data at one time you need that real estate. Just for grins, I once kept adding data PIDs to see how many live data graphs the MX+ could handle. I stopped at 40 simultaneous graphs (got bored). I was surprised the MX+ dongle, which is Bluetooth connected, could handle that mush concurrent data. I've used $2000+ scan tools that struggled with 10 or more graphs, and their DTC's were wired (not wireless)! If you do get he MX+ and use OBDwiz, you'll need the Professional Ad-on to garb more than four graphs at a time. It's like $40.
Beyond the MX+/OBDwiz... I have an Innova's 5610, Innova 7111, TopDon, Phoenix Plus 2, and TopDon's Phoenix Scope (oscilloscope). Also have a smaller Launch model, which is collecting dust. But honestly, with all this $,$$$ hardware, I still find myself at my laptop using the MX+/OBDwiz if I'm just looking at live data and freeze frames.
