Ryley Coker Posted May 19, 2021 Report Share Posted May 19, 2021 Alright, the car runs, IAT works. The LAMDA is wired into the CAN H/L setup. The switch power and ground come from the old MAF wiring harness. I followed the directions on the setup. But it will not read with the ecu to pick up on the computer. It shows LAMBDA on channel 1 I believe, but thats it. Thoughts? Quote Link to comment Share on other sites More sharing options...
Vaughan Posted May 19, 2021 Report Share Posted May 19, 2021 attach a copy of your tune and a log please. Is it a Link CAN Lambda? Quote Link to comment Share on other sites More sharing options...

When I get to the car tomorrow I’ll attach one. Vaughan 1 Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 20, 2021 Report Share Posted May 20, 2021 While you are at it, give us some photos of the CAN connection to the ECU and at the Lambda end as well. Quote Link to comment Share on other sites More sharing options...
Ryley Coker Posted May 24, 2021 Author Report Share Posted May 24, 2021 We are up and running. One of the grounding connections with just a tad loose. Quote Link to comment Share on other sites More sharing options...
Christoforos Posted May 26, 2021 Report Share Posted May 26, 2021 Hi, I recently got my G4X plugin ECU for WRX V1. I also connected the CAN Lambda as per the instructions and I did the set up at the PC software. I don't know if it works as I did not start the engine yet. My concern thought is regarding the power to the coil. The diagram shows that the coil is energized by the ignition switch. During cranking though the power to the relay is interrupted (as we all know) and once the engine is started it will be energized again. Is this OK or does it need to be energized also while the machine is cranking? Thanks! Quote Link to comment Share on other sites More sharing options...

Ignition circuit should not be interupted during crank, if it did you would have no fuel or spark. Only the ACC circuit is turned off during cranking.

Christoforos Posted May 28, 2021 Report Share Posted May 28, 2021 You are right Adam. I mixed up with the ACC! Thank you for correcting me! Quote Link to comment Share on other sites More sharing options...
