nabera Posted June 20, 2020 Report Share Posted June 20, 2020 Hey everyone, just wanted to create this topic as way to kind of track my progress on getting a Link ECU (TST185+) installed on my MR2. I purchased the PlugIn ECU however I will be running a full custom harness and lots of changes to the stock configuration. This is just sort of a fun side project so it will be a learning opportunity as well. I am probably in over my head but I work slow and methodical so I think I can work through and learn what I need. Anyways I just got the ECU and while I wait for the machine shop to finish up the engine I am going to start planning the harness. The plan is to leave anything that doesn't directly involve running the engine alone and basically have a dedicated engine harness. Why I chose the PlugIn? Well I like the idea of keeping things as OEM looking as possible. Although I will be adding a lot of things like a COP set up and removing the distributor for a CAS, the idea is to make these things look as OEM as possible. It seems the PlugIn ECU provides more than enough I/O for what I need, but I'll just need to significantly change the configuration. Here are sort of the major changes or additions to the OEM set up: TST185+ ECU DW Injectors (820cc) (18U-00-0078-4) Denso COPs (6731300) Hall Cam & Crank sensors (Racer X) Link 3bar MAP Link 3 way Boost Solenoid GM IAT (3/8 NPT) w/ KO Racing Cold Start Injector Adapter Plage Walbro FP Remove EGR Remove Fuel Pump resistor Remove OEM o2 Remove AFM There are still a lot of unknowns for me. I will probably ask a lot of noob questions after thorough research. Here to learn. My goals for the car are stockish power. Not looking to run more than 1 bar of boost on a CT27. I have a ton of supporting mods such as: 4" Intake (Racer X) 3" Downpipe (Berk) 3" Exhaust (Berk) Upgraded IC Core and Piping (TCS) CT27 (ATS) Rebuilt Engine* The rebuilt engine is in progress. I picked up a JDM 3SGTE with a spun rod that had JE pistons. The machine shop is checking it over and will advise what is salvageable. I have the stock GEN2 3SGTE that the car came with I will use as a fall back. Quote Link to comment Share on other sites More sharing options...
koracing Posted November 11, 2020 Report Share Posted November 11, 2020 Why are you getting 820cc injectors and only planning to run 1 bar of boost on an upgraded stock turbo? Are you considering upgrading to a larger turbo later on? I've seen some signal issues with your chosen cam and crank sensors - so I would make sure it's all working well with the OEM sensors first before attempting to install and then trouble shooting issues with these pieces, or give yourself a reversible path to do so -- maybe make the cam and crank sensor signals plug into a sub-harness that can be changed depending on the trigger types and connection points.
