How Do I program new CIM to Astra H With Tech2

Tech2 can't do without online access because it requires security authorization. OpCom is go-for in this situation

OP-COM is good enough for this.
Security Acces can be obtain offline by Tis2000 or Global Tis too

Good luck

If you have good op-com china clone you can use without problems even the last original/official ( uncracked ) OP-COM softwares. ( OP-COM Professional 210420b or Advanced 220314c EN )
If you are using cracked OP-COM softwares maybe that's why you have many issues or bugs.
If you have Tech2 hand held or GM MDI with Tech2win you can do it too. Using this maybe you will need Security Acces and carpass too.

Good luck

I have Genuine Tech2 and Genuine MDI With Tech2win I do have opcom but I do not trust it I think the software I have is shite iw Ould use if I knew a good trusted version of it
