SC350Z Posted June 30, 2023 Report Share Posted June 30, 2023 Dears, I have to wire the Powertune dash to my G4x. (where there are already 2 link can lambda connected onto the G4x). Where shall I connect the cabling (Can H/L) from the powertune dash to what port on G4x board? What cable / extension do I have to buy for G4x? And finally...what setting are needed on G4x? Thanks for you help Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 30, 2023 Report Share Posted June 30, 2023 What ecu do you have? Probably easiest to connect it to your existing bus for the lambdas since the wires are already there. Set up instructions are in the power tune manual. Quote Link to comment Share on other sites More sharing options...

Powertune dash has 2 wires to connect to CAN port on ecu. Was wondering what port to use on ecu. Or as you said if I've to connect to lambda bus directly...In this case, how does it work?

CAN 2 is used for the OEM bus. 5 hours ago, SC350Z said: Or as you said if I've to connect to lambda bus directly...In this case, how does it work? Just like you have 2 CAN lambdas already connected, you can connect another. Quote Link to comment Share on other sites More sharing options...
Timboj Posted July 2, 2023 Report Share Posted July 2, 2023 You can daisy chain as many devices as you'll ever need in a car. Great excuse to learn wiring basics: Quote Link to comment Share on other sites More sharing options...
