Hi, 

Was wondering if I can Control the Alternator from PCLink to shut if off at full throttle like is possible to do in the MoTeC M800 ECU...

 

Thanks

The F terminal is not connected on our plug-in as it generally causes more issues than it solves having the battery voltage suddenly drop when you are at full power.  But if you want to do it you will have to shift that wire or connect a spare aux to it.

Thanks Adamw,

Can you post some more details ?

Thank You

Sorry I said "F terminal" previously, it is actually the "G" terminal that you want.  

The G terminal is originally connected to ecu pin 41.  You need to ground this wire to set the alternator to low voltage mode.  

If you car doesnt have the IC spray function you could move the G terminal wire to ECU pin 35 (ign 5).  If you have IC spray and want to keep that functional then you could connect the G wire to one of the spare auxes on the expansion connectors.  

 

You can then set up a GP output to control whatever aux you use with the conditions you want to switch the alternator off - for example TPS > 80% & RPM > 4000.
