Discussion and questions related to the course Link G4 Software Tutorial
That it is better to use for connection to v88,i88 ?
30-2340 - 4 Channel Wideband UEGO Controller or 30-2340-N - 4 Channel Wideband UEGO Controller - For use with Nascar McLaren ECU via CAN
The CAN configuration for the Link G4 and V88 is too restricted to take the input from the AEM unit however you could use the 4 ANV outputs and wire those inputs although you would obviously use up 4 inputs. On the G4+ or i88 you could take input from the AEM unit via CAN but the ECU isn't currently configured to take 4 lambda channels. You would be able to input these and configure them as 4 AN voltage inputs via CAN. They would read as a voltage input however they would be scaled as lambda. This is going to be useful for logging or while on the dyno however because the ECU is considering them to be voltages, it can't perform closed loop fuel control using them.
I would use the 30-2340 unit. this is the one I'm using with our Toyota 86 and the user manual has the entire CAN template so you can correctly configure the ECU.
