Like you say, the threshold is not adjustable. It's also not predictable, and not matched to the ECU's reference. The offset voltage is doubled, too.

But you could make it work if you feel that my design is overengineered.

Sorry it is not to offend your disign, i am just trying to understand it??

Maby i am wrong but if the ECU dont "see" a voltage higer then the 4.3V it won´t fuelcut.??

No offense taken -- that comment was meant kind of tongue-in-cheek.

Yes, you are correct about the voltage. The actual number seems to be about 4.3 volts for North American Legacy Turbos, but it may be different for you.
