All in all, the two scan tools are amazing. If you are an experienced enthusiast or a beginner mechanic you could consider purchasing Launch CRP129.

But if you completely have to choose one then there’s a simple way of deciding which one it should be.

Consider your budget and needs. In case you are cash strapped you can go for the Launch CRP123, it is cheaper.

Launch CRP123 is a great pick for average car owners or DIYers.

But if you want a wider functionality and coverage then the Launch CRP129 should be your priority.

The Bottom Line

Both scanners are good and you will get real value for money regardless of the one you choose.

But remember, while the Launch CRP129 covers almost all OBD2 vehicles, the Launch CRP123 only supports those made in 2006 and later. Don’t choose the latter mistakenly if your car isn’t compatible.

In terms of functionality, you will get almost the same features. But the Launch CRP129 has a few more advantages than the Launch CRP123 which in turn is cheaper.

  1. I just purchased the Launch CRP 123. Software updates are free for life? Also will this unit tell me if the ECM is programmed correctly or there is fault? I have a rough constant idle and the steerin g wheel vibrates when the engine is cold, but improves when warm. Drivability is ok. Engine mounts are Ok. Can you answer these questions. Were can i get a free user manual. I see them on the Internet with about 45 pages but may cost?

    thanks EJR
