USB to Serial Adapter For MegaSquirt PNP Gen 2
Ensure you have a proper connection to your laptop while tuning your 86-95 Mustang with a MegaSquirt PNP Gen 2 with USB to serial adapter! DIYAutotune highly recommends this adapter to be used if your tuning PC/laptop doesn’t have a DB9 Serial connector. No CD is required with this adapter; simply download the drivers linked below, and you'll be tuning in no time! The adapter USB connection is on one side, and a DB9 serial connector is on the other. A short USB extension cable is included so you do not have the heavy adapter plug hanging out of the side of your computer or laptop for a more solid connection.
