Hi Rusty, I think that part of the problem is that you did not have an enrichment circuit that briefly increased injector open time as a function of butterfly opening speed; same idea as an accel pump on a carburetor.  If you look at TBI injection systems in automobiles ( or a v8 with a 4 bbl on a tunnel ram for that matter) they have longish runs and no hesitation problems. 
 
Hi Ian,
 
Well, the EC-2 does have a virtual accelerator pump function, though it isn't adjustable by the user.  Being able to increase that function would certainly have helped, but it wouldn't help the throttle closing problems.  Even with a fully adjustable enrichment feature, aren't you just using it to cover up a bad design?  
 
Cheers,
Rusty (Kolb turbo?)
