    Free yourself from the constraints of the factory ECU.

    The Link G4X MR2Link V3 TST205X PlugIn fits the Toyota MR2 V2-3 & Celica ST205. The ECU PCB fits discretely inside the original factory enclosure. 

    Installation of Link's Toyota MR2 TST205X ECU is a breeze - no alteration of the factory wiring loom is required. A built-in connector (or pins in some models) provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches. 

    Factory features are supported - see Features for any exceptions.

    MAP Sensor not included.

    CAN Lambda Link’s CAN-Lambda is an easy to use CAN-module that provides digital wideband sensor control via CAN bus and is compatible with leading aftermarket ECUs.

    The CAN-Lambda’s ability to measure the proportion of oxygen in exhaust gases makes it an essential tool for accurately tuning fuel mixtures as well allowing your ECU to make tuning adjustments on the fly. 

    Being fully digital the CAN-Lambda’s powerful LSU 4.9 sensor will eliminate any loss of signal, risk, delays and errors that analogue alternatives cause. The CAN-Lambda never requires free air calibration.

    LINK MXS 5"

    The LINK ECU MXS Strada Car Dash Display is the evolution of MXL Strada, one of the most widely-spread dashes on tracks and streets all over the world. The MXS Strada has a 5″ colour display with great visual impact, configurable to show lap times and all the info coming from the Engine Control Unit (ECU) , analog/digital inputs, pre-defined math channels and optionally, the GPS Module. Its data sampling capability can also be incremented adding up to eight expansion modules.

    LINK ECU MXS Strada Car Dash Display is a high colour, high contrast 5" TFT dash display ideal Street and race car/bike installations. The Dashes are available with (Road) and without (Race) icons and are fully configurable.

    The Road icon edition has Road icons down the side, which include turn signals, high beam lights, oil pressure, water temperature warnings and an engine check light.

    ** The Link MXS VERSION Has An Engine Check Light instead of a Low Fuel warning light. See Photos.

    You can configure alarm LEDs choosing colour, blinking frequency and defining the logic for turning them on or off. 

    The Aim MXS Strada Car Racing Dash/Display is for use on tracks and streets. It acquires data from the ECU of your vehicle making it relatively easy to fit.

    An additional socket on dash for a Reversing Camera.

    LINK MXG 7"

    Link MXG Strada 7” dash, powered by AIM.

    The Link MXG Strada Street edition is a full colour, 7-inch dash display legal for road use featuring 10 RGB shift lights and street icons down the side of the dash. It is pre-configured to work with all Link G4+/G4X Wire-In and Plug-in ECU's. See features tab for more information.

    The Link MXG Strada Street Edition dash features customisable shift lights, six street icons and a high contrast 7” TFT screen display. Visual quality is always optimal as the ambient light sensor auto-adjusts the brightness of the display. 

    The 10 multi-coloured RGB shift lights on the MXS Strada can be customised to your liking to define the RPM threshold for each single gear. There are also 8 Street Icons located to the side of the screen. These include an indicator lights, headlight, high beam, check engine, oil pressure warning light, temperature warning light and fuel light.

    The dash is extremely easy to use, with buttons on the side to navigate through a library of preset display styles, depending on what information you want to see and in what layout. The screen can display all real-time information reading from the ECU such as RPM, speed, water temperature, oil pressure and much more. 

    The Link MXG connects directly to your Link ECU via the pin kit and wiring provided in the box.
