Pro-CS

This question is for the one's that have used the GromCalcTool for long time and know exactly what licenses are needed to do the work.

I have my shop and do a lot of airbag computer reset, right now I'm using CarProTool (CPT) but it's being doing wrong, so I need a second programmer but more reliable and looking at this it seems to be my best option, so my question is.

What do I need to purchase (tools and licenses) to be able to cover all Renesas (RH850, H8SX, etc) Infineon... ok all ECU's. And if possible with K-line, Clear options or on board pinouts.

Please advise if the full package is my best option or buy separate. 

If full package is the best option, Do I need any extra tool or license to cover every single ECU (Including looked and tricore), all car brands.

Thanks for your help

My friend, I'm new to the forum, is there an specific area for english speakers, or just post my comments on the general section?

Please advice, Thanks
