Hey guys I’m having a bit of an issue. I have got everything plumbed in and plugged in the car will crank and I know it will start. But when i have the car on and tuner studio open and i try to start a project i get this pop up (see picture) and i don’t know whats older megasquirt or TunerStudio. My buddy has the same software and a running car on megasquirt and even that computer won’t connect it just says miss matched firmware. Where do i start in terms of trouble shooting. Where do i get the correct firmware, its no where on my computer or the usb provided with the ms3. This is a brand new ms3 pro pnp from diyautotune.

 

Have you tried googling ms3 1.5.1 ?
