  1. Toyota MR2 SW20 turbo, it was using the stock narrow band knock sensor with 1 pin. The new one will be running the donut 2 pin with new shielded dual core tefzel straight to the ECU plug. I think we might be all good though as the supplier where I got the knock sensor from said it doesn’t matter which pin goes where, as long as 1 is to the knock pin and the other is grounded. Which I assume it should be grounded to sensor ground and the shield from the wire to another sensor ground?
  2. Hi, My car is currently at a shop and they need to know which wire is what on a Toyota Donut knock sensor Here’s a picture of the connector plug. Thanks in advance
  3. Hi Kris, Sorry for the later reply. In regards to running the oil pressure sensor I take it you run it remotely on customers cars so there’s less of a chance of the fitting/adaptor snapping off? If so what size lines are you running to remote mount the sensor? I’ve also been looking at the Rife sensor blocks lately just unsure which way to go as I like the clean look. Here’s a link, they come in 2 3 and 4 sensor banks. https://www.motionraceworks.com/collections/pressure-sensors
  4. I just checked my stock ECU and it is 89961-17460 I guess it’ll be better to run dedicated sensors for temp and pressure from different locations for better accuracy as opposed to combined? I currently have a SARD oil filter sandwich plate with a temp sensor for my defi oil temp gauge. Perhaps it’s best to use that and send that into to the ecu. Yes the Syltech sensors do look interesting as they are Deutsch DTM, just need to figure out if clearance is ok depending on where they’re mounted.
  5. Hi Kris, Thanks. I’ve actually finished the test patch harness, just need to pot it and test it out. The files have been changed, below are the latest ones. Also it’s a JDM rev 3 car with a gen3 3sgte.

  6. Hi, I’m hoping if someone can help me by looking over the following PDF files I created to check if I have everything in order before I start wiring the ecu into my car. Vehicle is a 1994 Toyota MR2 turbo ECU is a G4x xtreme x wire in I decided on the wire-in version instead of the plug in as there’s more I/O available as the plug in version doesn’t have a few pins exposed. Additionally there’s a possibility I might do an engine swap later on down the track hence going with the wire in. The plan is to make a patch harness which connects to the stock wiring loom, however I noticed there’s a few incorrectly labeled pins from diagrams I found online compared to the labels printed on my stock ECU. I’ve copied the G4X MR2 LINK V3 plug in pin out (so I can play around with the base map) found in the online manual and have matched up most of the corresponding pins to A and B looms. I just need clarification regarding the grounds, which ones to use for which pin off the OEM loom. I take it anything sensor based uses the Shield/Gnd or the Gnd Out? The pin positions highlighted in red (middle pin out diagram) do not have connections from the stock ECU loom plugs. (Top diagram is from a website I found online some with different labels, middle one is what matches mine.
