you dont need custom map


the stock table can effectivly disable overun fuel cut


go to ecutek maps
select folder Fueling then Overun


open the Overun cutoff table


This table shows the rpm at different coolant temps where the ecu re-enables fueling


so if its got 1300 rpm means the ecu on overun stops fueling till rpm goes below 1300


so if you make those numbers big like 4000 it will fuel on overun to 4000.


note you will increase fuel consumption


as overun fueling is not an input to custom map it not easy to do in custom map

you dont need the custom map it will likely cause weird issues with idle when the ecu transitions from overun to idle mode you ill likely over fuel it if you use the custom map.



all you need to do is change the standard overun fuel resume table, maybe dont male it 7000, 4000 is likey enough, assume your just trying to create some pops and bangs ?


you can do that with just ignition retard in base timing at low loads
