G4 GTRlink engine fan

Recommended Posts

Hi team

I have a g4 pnp gtrlink, I'm trying to get only 1 fan going to start with using the stock Aux Inj 8 pinout which has been assigned to Engine fan.

I hooked up pin 6 from the ecu (which is aux inj 8) to the same cable that I had an aftermarket fan controller hooked up to which goes to my relay.  It works fine with the old fan controller, but when I plug it into the Link and set it to test on either low or high it won't switch the fan on.

Any thoughts before I pull the multimeter out?

Thanks in advance

Ok, set the 12v switch to be bridged with the 12v ign into the relay, and the link is now the ground.  Test works.

Is there a way in pclink I can have a display or gauge to know when it switches the fan on? otherwise i'll put an led somewhere

Worked out that I can do it with the runtime list.

On a seperate note, is there a way to do peak type gauges? I'd like to know peak boost and peak int duty cycle.  At the moment I'm doing it by data logging, then looking at the parameters list view properties to get the max value.

Is there a way I can also display if the ecu is running in CLL? couldn't find it under the run time list

You can also right click in some spare screen space and put in a digital gauge. There is no way to do a peak type gauge. For Max boost and Max inj DC% without ECU logging you an look at the ECU Statistics.

Looks like ECU stats is what i'm after, just need to clear them each time.

Is there a gauge for the NB oxy? or a way I can tell if the ecu is in CLL mode?

You can create a gauge for the narrowband O2 signal by right clicking in some spare space, selecting the gauge type you would like (maybe dial?) and then selecting the AN Volt channel that the O2 sensor is wired to. A narrowband O2 sensor typically oscillate up and down either side of the dither voltage. So although you may find if you are currently richer or leaner than stoichiometric, they will not tell you by how much.

The easiest way to tell the CLL status is to open the runtime values window (r key),  go to the fuel tab, and in the bottom right hand corner you will find the 'Lamba Status 1' parameter.
