Relay system for clutched supercharger pulley

[turbospace]

I have a blitz supercharger kit for an altezza with a link ecu and I was wondering how to output a signal to a relay based on throttle position target (say around >50% with a deactivation when it drops below 40% so that it doesn't stutter on and off if I'm at the 50%) how would I go about setting up this signal.

Use the Hysteresis example below.  SW cond 1 will be your 40% value and SW cond 3 would be your 50%.

I'm also finding a hard time finding an appropriate pin output, does the altezzalink ecu come with spare aux outputs for this purpose or do i have to buy an expansion loom.

Aux 5 and Aux 6 may be possible to repurpose for this as they are listed as ACIS variable intake control and Purge respectively.  There is also the Injector 6 output being used as o2 sensor heater ground for the oem narrow band o2 sensor that could be used.  If you need those functions to be retained, then Aux 8 on the expansion should work via an expansion loom.

Okay thankyou I'll repurpose the purge/aux 6 since its the least useful one, thankyou for the reply. I thought there would be a few spare aux outputs with how many pins that looked free but realised alot of them were NC.
