considering what it has taken for them to develop the few accessories for the maxisys I would say most certainly not. The need for one also is not nearly as great as it once was anyhow.

 There are plenty gas analysers. Don't see how this would add something to current tools?

If you could explain, Autel might see and consider too?

We can already read trims etc. and do gas test with excisting gas analysers?

 Yes... And if you want I can recommend a good gas analyzer that is able to read the 4 gases and you can add NOX.
