anti lag ignition cut

[fetzi]

hello,

i have one major problem by understanding the parameters for the anti lag system on the m800.
ignition retard is clear for me.
but what does the ignition cut parameter?

Now i have about 30% ignition cut and 35 degrees ignition retard but i am not able to build boost.
there is enough air from a bypass (I think so).

thanks for your help.

regards
fetzi

Hi Fetzi,
Cut in MoTeC terminology means the percentage of ignition or fuel events that are stopped. If you have 30% ignition cut then 30% of the ingition events do not happen, the ECU stops the sparks from happening.

Hi there,

I think you should Open the Motec ECU Manager and Go:
Adjust->Functions->Boost Enhancement (Anti-Lag)->Fuel Enrich/Enlean Table

and fill the table with the %extra fuel that you want to inject for TP i.e. 0% until 30% and RPMs 2000 until 6000 (i.e. 7% for 0% TP, 6% for 10% TP e.t.c.).
Since you bypass air at the exhaust manifold (and you are sure that the bypass valve is working properly), propably you neeb the extra fuel for the "bang"...
