Show original supplier description
The LinkECU MR2Link V3 (PN: 222-4000) is a G4X PlugIn ECU that brings the latest engine management technology to your vehicle, aiming to help you maximize its potential. This ECU is specifically engineered for the 3SGTE engine found in select Toyota models. It supports most factory features and offers significant I/O expansion options, detailed in the features tab. However, it's important to note that this ECU is intended for manual transmissions only and will not fit in the original housing of non-turbo cars. Additionally, a modification is required before E-Throttle functionality can be utilized. Suitable applications include the Toyota MR2 from 1993 onwards (Gen3 3SGTE, excluding RedTop Beams), and the Celica ST205 models such as the Carlos Sainz Edition, GT-Four RC, and Group A Rallye. Before purchasing, verify that your vehicle's pinout connector matches the header shown in the product images.
