randolph Posted November 15, 2021 Report Share Posted November 15, 2021 Hi, i’m having some confusion between what the can lambda manual say and what the link ecu product on sale, in the can lambda manual it says to use 18 awg wire connected from relay, but on the other hand the link part number: canext that is suppose to connected can devices directly(cleaner) uses a much smaller gauge of wire.i have include to pics, one displaying how i’ve connected 4 link can lambda and one can gauge(functioning) and one pics of the link can lambda instruction. My question and concern is if the small gauge power wire is large enough for all these devices or should i go with the manual and add a relay to power up the 4 lambda modules, thank you Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 15, 2021 Report Share Posted November 15, 2021 Yeah you might be pushing it there. The CANEXT power wires are only 0.5mm2 (~20AWG) and were not designed to take the load of 4 lambdas. I only tested 2 lambdas at the end of 2 CANEXT's when designing those cables. I would suggest making a heavier one for the first one which has total current going through it. Quote Link to comment Share on other sites More sharing options...
