Keith Tan Posted August 7, 2010 Report Share Posted August 7, 2010 Hi guys, Its my first time using the G3 today. Its a nice ecu but i have to familiarize myself with all the functions to make full use of it. First of all, i want to wire my Innovate LM2 analogue 1 into the G3. When i pull down the analog input 0-5volt, i could use it for wideband #1. May i know which ecu pin is this? Where should i wire the grounding? Sensor ground or the main ground? Thanks guys!

Kristian G Posted August 21, 2010 Report Share Posted August 21, 2010 use LM programmer to set up LM-2 AN out to 0-5v linear. Then connect - (minus) lead from above AN out to ECU sensor ground (grounding to chassis where ecu are grounded will work ok) and then connect the + lead to the ECU`s AN in 1 or 2 depending on which one is available on your application. If you look at the ecu booklet you`ll find the pinouts there. last time i used this ecu AN-2 was pin no 5 starting from upper right looking at the back of the ecu connector. (note! the ecu connector, not the plug in board if your using that for your car) Quote Link to comment Share on other sites More sharing options...
Jurgen Biggelaar Posted August 31, 2010 Report Share Posted August 31, 2010 Hi Keith. If your still trying to wrap your head around it, Kristian has pretty much nailed the question well. Below are links to the two manuals available depending on what type of G3 you have.
