RX7 FD3S - Haltech or Aem Boost Trim Pot

[Copyninja]

Evening Gentlemen,

Is it possible to add a rotary style 12 position trim pot on the digital input of a Link G4+ expansion loom?

I currently have it set to a simpler high and low boost trigger switch but was looking to add a bit more control over my boost range like from low boost of 10psi all the way up to 25 psi. 

Kind Regards,

Pat

The usual method would be to wire it up to an analog input and use that analog on one of the axes of the boost tables.

I usually also use a cal table to convert the "voltage" into a knob position.  

From there you can either put it on one axis of one of your boost tables or use two tables and blend between them.Here are a couple of examples:

Thank you, I suspected as much. The issue im having is i haven't got any spare an or analogue inputs. I currently have a boost trigger for high/low boost connected to a digital input on the expansion loom. 

I'm not using the RX7 OMP control....is it possible to configure that analogue input for the boost control switch instead?

Sorry, I didnt originally notice the reference to Digital input.  Yes you can use the old oil pump postition wire (AN volt2) for a boost knob.

Thank you Adam.
