Adaptronic Users:

  • To connect your Innovate Motorsports MTX-L PLUS: Wideband Air/Fuel  Gauge to the ECU you will use the Molex to Molex Patch cable (inn3812) to go from the Out on the the MTX-L PLUS to the IN S1 or S2 on the Adaptronic Modular ECU. 
  • To allow the Adaptronic ECU to know that you are using a wideband over Serial you will need to go to the inputs tab > O2 / Lambda Sensors, O2 Sensor 1 - Set the connection to Serial Only 
  • To allow you to see your A/Fs in the Eugene software you will go to Functions > Serial Comms - Serial IN 1 or 2 - Set the connection to Innovate - Type None, Number of MTXL, LC2 or LC1 connect to 1. If you are daisy chaining TC-4 Plus through the Innovate MTX-OL PLUS wideband you will have this device be at the begining of the daisy chain and the out will go to the IN on the MTX-L wideband and then the out from the MTX-L wideband will go to IN S1 or S2 on the adaptronic Modular ECU and the Number of MTXL, LC2 or LC1 connect to 1.
  • The Gauge type in Eugene will be AFR (Petrol) or Lambda depending on what unit you have chosen in the home tab under units.
