FLAT SHIFT problem

Hi
I am using launch control and today I try the flatshift . Problem is when I want to change gear at 7000 I press the clutch it activate flatshift button and it must go to my setted 5000rpm but with only spark cut it can not even if retard to 10 degrees ATDC and stay at 7000rpm so I must use spark and fuel cut , then will have another problem if I use spark and fuel cut it will be for flatshift and launch control , but launch control can not work with fuel cut it must be only with spark cut .
Can you add different revlimiter types to chose for launch and flatshift also if someone work on these functions - they need enrichments during launch on also can see VEMS menu for antilag it is usefull : http://www.vems.hu/files/MembersPage/Ga ... window.PNG

How aggressive is your spark cut? I use something like 5 out of 6 sparks dropped spark cut only and it holds at 4500rpm with foot to floor. It is very loud during shifts though.

It 3 from 5 because I want to build boost before launch .
When you say that holds 4500 do you mean that before cuts RPMs were 7000 and when it cut the go immediately to 4500 because shifting is about for 0.3 sec RPMs must go to 4500 in that time

Yep. I shift at 6000, but yes, the rpms drop down until I release the clutch.
