Description

The Link ECU MR2Link V1 - TST185X is a G4X PlugIn ECU engineered to help you unlock the full potential of your vehicle's engine management. It is specifically designed for the 3SGTE engine. This engine control unit is built for reliability and affordability, offering advanced engine management technology. It supports most factory features and offers I/O expansion options detailed in the features tab. For optimal performance, a Link Air Temp Sensor is highly recommended. This MR2Link V1 ECU is exclusively compatible with manual transmissions. Additionally, a modification is necessary to enable E-Throttle functionality. Before purchasing, ensure your vehicle's connector matches the header shown in the product images. Suitable applications for this ECU include the Toyota MR2 (SW20) produced between 1989 and 1992. It also fits the Toyota Celica ST185, with the exception of the GT-Four RC/Carlos Sainz Special Edition models, which require the Link TST205X Plugin ECU.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
