I’m deciding which scanner I should get. To see live data, command things, relearn, etc and find the cause of a persistent cylinder misfire. And is more convenient to keep on the long run.

So I have a 2012 Buick verano 2.4L recently messed with the timing and after assembling I have a dead cylinder on cylinder #4. And tested everything to see if it was something else because I did a lot of work on it but everything was good besides timing which i don’t know if I did it right because timing looks off when cylinder#1 is at true tdc . How can I retime or is timing good ?
