You can use the canon of the mek to tame it its a lot more easier

To knock this humongous Dino just simply agro it on a quetz a shoot rockets at its head, it will make a noise if done correctly.

You can’t knock out with any tranq arrows.

Tek can knock out titan, tek tape is the best way, up vote so the devs will add tek stuff to the tame bar

Ok guys so all you need to tame it is a titanosaur platform saddle. It doesn’t eat anything and you don’t need any narcotics to tame it. Once you knock out the titan, place the saddle in it’s inventory and equip it to the titanosaur. Boom you just tamed a titanosaur! You’re welcome!
