Link G3 ??? Digital Inputs

Recommended Posts

Hi All,

Photo of my ECU attached... I was told it was a Link G3 ? What I am struggling with is finding which wires are the digital input switches? I want to have one switch for anti lag, one for switching maps etc 

Any help much appreciated. 

Cheers

Sam

Not a great photo but yes it looks like a G3 LEM.  The G3 only had 1 digital input and it is possibly already used for OEM functions that the adaptalink connects to - for instance vehicle speed sensor.  You will need to look at the map to see if it is assigned to something important already.  

Pinout is on page 16 of the manual:  http://forums.linkecu.com/applications/core/interface/file/attachment.php?id=2542

Thanks for the reply. 

And wow... Just one input, so assuming this is already used, how would you recommend the best way to switch antilag on and switch fuel/ignition tables etc? Apologies if this is a silly question, appreciate any info and guidance. 

P.s on the software it gives me options of loads of DI's... Is that just because it doesn't know which exact ECU I have?

If the Di is in use already and is a needed input then you haven't really got any options as far as switched maps or lag goes.

The G4 firmware would give you a little more flexability in that is does have "virtual auxes" that you may be able to use.  You can use a virtual aux to turn on/off something based on a set of conditions.  Have a play with a G4 base map and you will see how it works.  

As an example if you had a spare analog input, then you could connect a rotary switch to that and then set up a couple of virtual auxes to enable when the switch is in different positions.  So for instance you could have position 1 is antilag on, position 2 is high boost map or whatever.
