Question olderguys autotune as O2 clamp for EMU

Hi,

because I switch to the EMU now and can't seem to sell my olderguys autotune, I will try to use it as O2 clamp for my EMU.

Anyone has an idea about how to connect? Maybe Bruce can help me?

Is the trigger for PIN 14 at the EMU +12V or -12V? The OG autotune is switched by a -12V pressure switch.

If the trigger at the EMU is +12V - could I just sitch the autotune ground and connect the yellow and red wire to +12V?

Thanks,

O.K. I found in some older threads that the trigger for the vtec pin 14 is +12 v. So I will try to use a automotive relay to switch a ground to the yellow wire on the OG autotune. This should give me the clamping voltage everytime the aux map ist set to on.

Do you think a standard automotiv relay will handle the relatively frequent shifting for a reasonable time?

Thanks
