The Gotech MFI Pro system is an Upmarket version of the standard MFI ECU. This unit has additional features allowing greater control over Engine management. The ecu contains many more components providing for the greatly enhanced functionality. This ECU offers outstanding value for money and is much more than just "Competitively Priced" This unit can now be used on 5 cylinder coil per cylinder vehicles and eight cylinder wasted spark vehicles as well.

General Purpose Outputs (GPO)
Uses of General Purpose Outputs (GPOs)
♦ Switching of Shift Light ♦ Variable Valve Timing (VVT) control ♦ Used to trigger a Nitrous Oxide System ♦ Switching a fuel pump ON or OFF
Ignition Control Features
Full control over ignition timing at preset RPM intervals and 32 load intervals
Interpolation between load points for smooth timing transition.
Ignition control input provided by engine speed and manifold pressure. (software mixable)
A rev limiter is provided to prevent dangerously high RPM to be exceeded.
Progressive 3-stage gearshift RPM warning lights provided to remind driver to shift up.
Ignition is fully configurable using serial link to P.C. or laptop.
Gotech PRO ver5.3 is software provided for easy tuning. (Windows)
Gotech MFI PRO with wiring harness, installation manual & CD
Ignition Timing RPM Ranges
Please note that the rpm levels indicates to where the engine can be tuned, you will however be able to rev past the maximum rpm of tunabillity. The last rpm range figures will then be used for all rpm levels after the maximum rpm.
1 Cylinder vehicles - Up to 48 000rpm in 2000rpm increments
2 Cylinder vehicles - Up to 24 000rpm in 1000rpm increments
3 Cylinder vehicles - Up to 16 000rpm in 667rpm increments
4 Cylinder vehicles - Up to 12 000rpm in 500rpm increments
5 Cylinder vehicles - Up to 9 600rpm in 400rpm increments
6 Cylinder vehicles - Up to 7 992rpm in 333rpm increments
8 Cylinder vehicles - Up to 6 000rpm in 250rpm increments
Rotary engines(Twin Rotor) - Up to 12 000rpm in 500rpm increments
