Hi Guys.

I have got a Ford Mondeo 1997. I bought bluetooth mini obd2 elm327 version 2.1 in ebay.com and this item came to me but didnt work 2.1 in my car. I want to down this firmware to version 1.5.
Elm327 version 1.5 is working in my car. How can i down my mini elm327's firmware from 2.1 to 1.5????
Thankssssssss!!!

Hello

No this is not possible, as the software is written to the PIC and can not be changed

This also does not make sense because there are other ELM interface v1.4 or v1.5 to buy for little money

And why should be wrong for your Ford Mondeo version v2.1 ?????
With Multiecuscan you can read at your Ford no control !!!!

Use times Forscan.org
