Need some help. Purchased a MS2PNP from DIYautotune for my 99. I'm having trouble getting my Macbook to connect to it. I downloaded Tunerstudio & am also using the USB to Serial connector. When I go to create a new project, it will not detect the firmware nor will it connect to the ecu

 

Did you download the OS X driver for the USB-Serial cable?

 

^I did not. Where would I be able to get that?

 

Sorry, I'm not going to dig it up. Look on the Tunerstudio's site

 

This look somewhat right?
Installing a USB Serial Adapter on Mac OS X | Plugable

 

Just because I am feeling too nice today: Virtual COM Port Drivers

 

Got it! Thank you! Just had to install the driver & everything works now

 

You are welcome. Might want to change the topic's title and add "Solved" at the end.

 

I wrote this a while back. Should also help you when you go to upgrade firmware
