POPCorn Diesel Rev Limiter, EDC15 VAG 1.9 TDI

Looking for advise on a simple fuel cut for the popcorn rev limiter as seen here: http://youtu.be/OVbZXo2TpRM (from ecu connections forum)

fuel is cut but is not making a popcorn style sound :(

Any Advice would be great, Thanks in advance. :oops:

Just a quick update guys ...

This is what we now had created http://youtu.be/RqEHyOd7PdY

Also we have created popcorn limiter for the EDC16, Not yet finished but you get the general idea. http://youtu.be/r8mDCD-xy3Q

Enjoy, Thanks again for all your help and a BIG thanks to Raffel !

I think is set down the IQ/torque Map a few before it end"s and left the rest normal !
but it look"s that don"t give any healthy to the motor !

I think it can be done by 'jumpy' change in torgue limiter. Stock TL map or curve is decreasing gradually, it means that injected guantity decreases gradually with rising RPM until engine have so little IQ that it can't increase its RPM further. But when you write here a sharp change, (for example from max IQ to zero in differnece of 10RPM) engine rise its rpm, cross the threshold, sets fuel to zero, rpms fall down, cross thresold, again set max fuel , rise rpm, cross thresold... and so on :) So I thing the key to victory is in fast decrease in torgue limiter in narrow rpm range. But it is only my idea :D i didnt try it .. Am I right? :) And also I dont want to know what must be happening in injection pump :D Poor setting solenoid have to change its position from min to max multiple times in second.. :? (in nonPD car of course :) )
