MS3 Pro Mini Setup with 8ft bare ended loom - £675 plus £18 postage

The MS3-Pro Mini is basically a sealed MS3X setup but with less outputs than the full fat versions. It also supports a wide variety of engines out of the box, with the ability to run anything with one to eight cylinders with sequential fuel injection and sequential 'coil on plug' ignition (up to a 4cy) or wasted spark up to a V8. Over 50 different ignition modes are supported, from mainstream applications like the GM LS1, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeeps and the Suzuki Swift GTI.

The MS3-Pro's packaging is where it differes from the standard MS3X setup. Instead of the industrial looking split aluminum case and D-sub connectors, the MS3-Pro uses a sealed high temperature nylon case for light weight and compact size, and heavy duty AMPSEAL connectors. This provides a compact and sealed enclosure protecting the sensitive internals from the elements. The MS3-Pro's design keeps the heat generated to a minimum, allowing it to use a lighter plastic case instead of a metal heat sink.

This package includes the MS3-Pro Mini, USB tuning cable, licensed Tuner Studio software and manual on a USB drive, and 8' wiring harnesses.

Note that the MS3-Pro uses an built in 4 BAR MAP sensor as standard.

Hardware

Freescale MC9S12X 16 bit, 50 MHz asymmetrical dual core processor
8 Outputs for High Impedance Injectors
(Unused Injectors can be repurposed as additional High-Current or PWM Outputs for General Purpose use!)
4 logic level ignition outputs - (Suitable for coils with built in Ignitors)
1 high current (5 amp) general purpose output - (Idle valve, boost control, etc)
Camshaft and crankshaft differential inputs - supports VR, Hall effect, and optical input
Fuel pump output
3 Digital Inputs, 2 are capable of high frequency input (Ex. Speed Sensor, launch control)
4 General Purpose Analog Inputs - (Datalog 0-5V signals from various sensors)
RS232 and CAN communication
Onboard 8 gigabyte SD card for internal data logging
Temperature range: -30 to +80 degrees C (-40 to +85 without battery for real time clock)

Software features: - (Virtually the same as an MS3X setup)

Supports speed density, alpha-N, or MAF based fuel and spark tables
1 microsecond injector pulse width resolution
Tables for nonlinear injector behavior at small pulse widths
Allows blending multiple load types, including specialized mode for independent throttle bodies
Supports a wide variety of OEM cam and crank position sensors
Individual cylinder trim tables for fuel and ignition
Accelerator pump or model based acceleration enrichment
Closed or open loop idle speed control
Closed or open loop boost control with gear or speed based tuning options
On/off or closed loop continuously variable valve timing control - supports up to 4 channels
On/off or progressive nitrous control
Traction control
Rally anti-lag
Rotary support - can run up to 4 rotor engines with separate leading and trailing spark tables
Staged injection
Table switching
16 x 16 fuel and spark tables - can be reconfigured to function as 30 x 16 or 16 x 30 by switching tables based on RPM or load
2 or 3 step rev limiter with no-lift shifting
Wideband AFR target tables
Flex fuel sensor input
Real time barometric correction
Safety shutdown based on AFR or EGT input
Sequential shift cut and air shifter control

Please note: There's no Stepper Idle valve output on the MS3pro Mini ECU and no designated Tacho Output. One of the injector outputs can be used to drive a tacho if you add a suitable pullup resistor, but only if you're not using all 8 outputs. The Idle valve output is a single channel, so only a 2 wired idle valve can be controlled.

MS3 Pro EVO Setup with 8ft bare ended loom - £1145 plus £18 postage

The MS3-Pro is basically a sealed MS3X setup, so it also supports a wide variety of engines out of the box, with the ability to run anything with one to eight cylinders with sequential fuel injection and sequential 'coil on plug' ignition, a V12 with sequential fuel (An MS3X can go up to a V8 as standard) and wasted spark ignition, or a four rotor Wankel with separate leading and trailing ignition outputs. Over 50 different ignition modes are supported, from mainstream applications like the GM LS1, Bosch Motronic, and Chrysler Gen III Hemis to unusual modes like Renix Jeeps and the Suzuki Swift GTI.

This package includes the MS3-Pro EVO, USB tuning cable, licensed Tuner STudio software and manual on a USB drive, and 8' wiring harnesses.
