Hello guys,

I use to work with the MED17 with TPROT in the bench, with KTAG.

But yesterday i went to visit my friend's new company and he bought the REVO technik tools.
He was able to read and write TPROT'S Ecu just flashing via OBD2.

Since i'm from Brazil, we don't get to know brands like REVO and might some more that is able to flash thoses ECU.

Can someone help me this out?
Wich brands or company should i go for Flashing thoses ECU?

Here's why:

No problem at all using KTAG, but my costumers kinda get scared when i tell that i have to open the ECU in the bench. Since it's all expensive here and prob lose warranty of the vehicle they are choosing others tuners instead me. Since they say that they are able to do it via OBD2.

Sorry for being "newb" but like i said i've been working for like 3 years and i only know MPPS, Dimsport, Alientech and APR, which all those have to bench most of the new ECU's.

Thanks alot for helping!
