Gaspar...doesn't/shouldn't the ECU just continuely re-adjust the pump voltage in order to maintain a stable idle RPM (55K for the 44-Gold)? Certainly if calibrated correctly on start-up....unless, perhaps, there is rapidly and large varying fuel system restrictions, e.g., beyond the ECUs ability to respond that fast. Which I think highly unlikely!

After all, the ECU is 'fast enough'/it quickly varies pump voltage to accommodate desired throttle demand/RPM extremes very nicely when all is well. So, I could understand a 'hunting' idle if there are truly changing fuel system conditions, but why it 'hangs' at a high idle is still a mystery to me. Unless, as you say it is solely a pump problem. And those of us w/ 44-Gold idle and flame-out problems have had them resolved almost solely w/ pump replacements, I believe.

I don't think we should be asked to up voltages w/ bypasses or replace our pumps as you suggest, however. I think Wren needs to resolve this and let us know just as soon as they have a capable, stable, and reliable pump. I've great faith they will!
