MegaSquirt Tuning Cable (DB9 Straight Thru)

What DIYAutoTune products does this fit?

• All standard MegaSquirts with V2.2, V3.0, or V3.57 main boards
• MSPNP Gen 2 models except EEC4A8 and EEC4B8 versions
• MSPNP Pro models except JZ9298
• All DIYPNPs

My computer doesn't have a matching connector. How do I make this work?

• Add our USB to RS232 adapter to connect with your USB port.

My computer has a 15 pin version of this connector. Can I use this cable if I get a DB15 to DB9 adapter?

• No. The 15 pin connector is either a VGA display port or a joystick port. Connecting either one to a MegaSquirt is likely to cause severe damage to the computer, the MegaSquirt, or both.
