sensors
• CAN, RS232, and USB connectivity
The original MS3Pro features an O-ringed, splashproof nylon case with AMPSEAL connectors.
1.2.1.2 MS3Pro Module The MS3Pro Module uses the same basic design and feature set as the original
MS3Pro, but the unit ships without a case and the AMSPEAL connectors have been replaced by 0.100” headers.
This board is designed to mount to a carrier board incorporating additional circuitry and connectors, such as with
the MSPNP Pro, or it can also fit inside most factory ECU housing for racing classes that allow any tuning device
as long as it fits within the stock ECU housing.
1.2.1.3 MS3Pro Plug and Play The MS3Pro PNP is a line of vehicle specific plug and play ECUs using the
MS3Pro at their core. The exact feature set and pinout will depend on the application. All models offer peak and
hold injector drivers for the main fuel outputs.
1.2.1.4 MS3Pro Ultimate The MS3Pro Ultimate is picks up where the original desing left off with more features,
including peak and hold injector drivers. It represents the top of the MS3Pro line.
• 10 fuel outputs for high impedance or peak and hold injectors
– User selectable 8 amps peak / 2 amps hold or 4 amps peak / 1 amp hold current
• 8 logic level spark outputs
• 3 high current general purpose outputs (2 of which can be used as additional fuel channels)
• 7 PWM general purpose outputs
• 1 tach output (0-12 volts)
• 4 VR inputs for crank, cam, and vehicle speed sensor input
• Optoisolated RPM input for fuel-only installations
• 3 high frequency digital inputs (2 shared with VR inputs)
• 5 digital I/O outputs that can work as frequency inputs or 5 volt logic level signals
• 6 on/off digital inputs
• 8 general purpose analog inputs
• 2 knock sensor inputs
• Onboard 4 bar MAP and 1 bar barometric pressure sensors
• Dedicated inputs for CLT, MAT, TPS, and O
