This might be very useful to those who are running the TTE supercharger setup with an adjustable voltage clamp piggy back ECU. Greddy BCC, Turbosmart FCD etc.
I have a Greddy BCC.

After a bit of searching the net and a bit of trial and error, I've discovered the voltage clamp can be set to 4.40V without hitting fuel cut. A few guys on toyota forums reported a fuel cut level of 4.44V on their Celicas.

I just took the car for a quick blast and it seems more eager to please at this new level. I didn't want to take it much past that in case I encountered problems.

It's certainly put a bigger smile on my face.

Mucho, Mucho, Boosto!

Indeed. Always good to share information :laugh:.
After i get back from a pending work trip I might try and play with the Voltage level some more to see how high I can actually get it.
Like I said ealier the actual fuel cut level might be 4.44V.

That's great news Talisker :w00t:

Now I kind of regret selling my supercharger kit. I've calibrated all my boxes to 4,34V, but it's easy to adjust it afterwards using the adjustment screw inside them.

It would be great to see some dyno numbers with voltage clamp at 4,34V vs. 4,40 or even higher.
