Feezy

You both are fantastic. Thank you very much for the clear explanations.

Sorry. I get that. I'm trying to understand in general would I ever add these other sensors to the CAN port versus an expansion port? I have been trying to read up on CAN and what it is, but I'm a little fuzzy on what sensors are applicable to it and why.

I appreciate both of you. I think I get the wiring of them in, my curiosity now is the difference between the CAN ports and the expansion ports. I have three expansion ports on the board, so I specifically want to use the E-throttle one, or is any of them ok to use? When would I want to use a CAN port. I bought the adapter for the Lambda kit, but outside of that is there a benefit or a reason to use those ports? Thanks again. I really appreciate the guidance.

I have some questions about wiring and updating my harness for a Link Plug & Play ECU for the S2000. I know next to nothing about wiring oor electronics so some of the questions are going to be pretty dumb, please bear with me. I have an S2000 (2002) with the F20c. I have the following sensors that are on the main harness but have different connectors. These are: - Injectors: Bosch EV14 - IAT: 2 pin DTM: https://www.t1racedevelopment.com/product/t1-fast-at/ - TPS: Toyota TPS: https://racespeconline.com/products/toyota-2jz-tps-connector-kit (I need this to extend to the firewall. The OEM TPS is at the front and this new set up is on the firewall) - IACV: Honda K Series - https://racespeconline.com/products/honda-k-series-iacv-connector-kit?variant=27749049537 - MAP: Honda K Series - https://racespeconline.com/products/honda-connector-1?variant=5688085086246 If I understand how this works, it's as simple as me depinning/repinning the new connectors in place of the old ones, and then telling the ECU what the new sensor is. Is that right? From there I am adding three additional sensors: Fuel Pressure: https://www.milspecwiring.com/150PSIG-DTM-RaceGrade-Pressure-Transducer_p_459.html Oil Pressure: https://www.milspecwiring.com/150PSIG-DTM-RaceGrade-Pressure-Transducer_p_459.html Oil Temp: https://www.milspecwiring.com/RaceGrade-18NPT-Liquid-Temp-Sensor_p_398.html How are these added? Where would I find the wiring diagram for how to incorporate these into the ECU? I see expansion slots, and CAN slots, and I have no clue which to use or why. Last question. If I'm having a full harness made for my set up should I have the wiring for the O2 sensor removed? I have purchased the LINK CAN 02 set up which I'll be running. Is there any reason to keep the extra OEM stuff in place? Thanks in advance for all of the help. I'm very much new with all these electronics and I'm struggling to wrap my head around it.
