Right, I was taking it the opposite way.

This is more clear now, thanks a lot guys!!

I understand now better the role of the precontrol actuator and how it pre-spools the secondary, causing spike.

I'll fine tune it and keep you posted.

 

Here are pics of my set-up and dirty engine bay .

I have still a little spike at transition but I'm confident that by keeping on fine tuning it I will get rid of it.

Thanks again guys!
