Description:

Hi everyone,
Selling my used MS3Pro Ultimate ECU with GM LS 58x Plug and Play Harness. It’s out of my personal twin turbo LS-swapped FC and is in perfect working condition. It would take very very little work to swap this into your LS-swapped RX7. There are multiple other people running this harness of LS FCs and FDs.
The harness is setup for a 58X crank engine, but can easily be converted to a 24X with the cam sensor at the front or back of the engine.
It also includes a relay/fuse box for the injectors, coils, fuel pump, rad fan, ect.
Harness is setup for Denso-style injectors (ID2000s) and stock coils and sensors. Can cheaply and easily be setup for different coils/injectors.
In addition to the standard PNP harness, I’ve also added the following sensor connectors to support a turbo application:
• Fuel Pressure
• Oil temp (in pan)
• Dome Pressure for CO2 boost control
• Dual Boost Control solenoids for CO2
• Exhaust backpressure
• Front wheel speed (hall effect)
• Rear wheel speed (T56)
• Reverse lockout solenoid (T56 and ECU controlled via vehicle speed)
• Coolant pressure
• Crankcase pressure
• Turbine speed
All other remaining inputs/outputs are bundled up and uncut.
I've also taken the time to label each wire so that it's as easy as possible for the new owner to install.
The $1400 price includes the price of the ECU and full harness.
