The problem is the bypass valve. It doesn't just expect it to be plugged in, it expects to see changes when it's activated. Don't forget Weistec reused the factory bypass. Trust me it's not as simple as tricking the computer into thinking it's still plugged in.

The bypass valve is does not move independent of the throttle body, they move in opposite fashion, ie the throttle is closed the bypass is open, and vice versa, in a an equal proportion. so it you wire the throttle body potentiometer signal returns to the signal returns for the bypass, it may trick it into thinking its still there and working in the correct fashion!? Just some food for thought

I am confused why this is a mystery on how it will work if Eurocharged already removed a supercharger from a SRT6 Crossfire and tuned it with a turbo? They are basically the same, just 2 cylinders less.
Is it that the ecu is way different and that is the problem? What was done on that turbo converted Crossfire that had a bypass valve and clutched pulley supercharger before?
Only took them 11 days to build and tune this. It appears the supercharger clutch is left in the engine bay over on the passenger side, you can see it and the electrical connection going over to it. But since they have a clutchless pulley tune now I would think they don't need to have something like that done and I could have swore there was an E55 in the past that ran a DTM intercooler or it was just a custom one with no bypass. Think it was VRP who did it back then, can't remember so no idea who did the tuning, etc.

32K came from factory without a bypass, only a clutched sc pulley, and since the tb is before the sc no need to bleed boost after the sc or the vacuum that is between the tb and sc when releasing throttle. very simple.
i run a 55k sc on the V6 without a bypass and still no modification with the 32k ecu!
but the clutched is needed for idle and cold start.

Now let's see one with the engine and some numbers.

Thanks man, so far sock engine and trans, we'll see how far it takes us, and go from there, the set up works even better than planned I am very happy with it!
