ellisd1984 Posted November 4, 2020 Report Share Posted November 4, 2020 So I've finally had enough of trying to find out why whenever I have a high electrical load the ecu needs to add as much as 10% fuel correction in closed loop to say on the desired lambda. I'm hoping the problem is my analoge widband so I've orderd a Can/Lambda module. My Question is I alread have a 4 pin connector which used to be for the stock narrowband sensor which has 12v, ground and 2 cables feeding back to the ecu (originally signal and heater switch). Can these be used as canH and canL or will there be problems with interference as they are ran with the rest of the cables in the engine loom? If I can use them is there a type of cable that should be used which connecting Can modules? I'm an electrician by trade but have no experience of this typr of system.

dx4picco Posted November 4, 2020 Report Share Posted November 4, 2020 I believe canH and canL should be ran through a twisted pair, and not regular straight wires. Depending on the length it may be feasible but I doubt on the stability afterwards Quote Link to comment Share on other sites More sharing options...

Adamw Posted November 4, 2020 Report Share Posted November 4, 2020 Nothing special needed. Should be twisted though. Quote Link to comment Share on other sites More sharing options...
