Hello, I would like to use both CAN Lambda and have an extension loom to control two fan relays. 

Unfortunately the factory fans are controlled over CAN and with my setup I'd need a analogue way of triggering the relays. 

Is that possible with this ECU, I believe I already have the Can JST cable plugged into the ecu?

Thank you.

It appears according to the help menu you have two 8 pin epansion plugs on the board as well with one of them having 3 aux outputs suitable to ground the trigger side of a relay to control your fans.  You'll need the XSL expansion loom for G4+/G4x plug-in ecus pn 101-0106.

You could use Aux 6 & 7 at the ecu header or already in the engine bay in the O2 sensor plugs, or if it is the non up-rev model with only intake VVT then you will also have Aux 3 & 5 spare at the ecu header.
