Hi

My rom is 52500010 when i make changes to high octan fuel map it has difference only at close loop, how can i change the open loop maps? i need another tables? where can i find them?

thanks in advance

 

you may have your terms backwards. open loop is what your are in when you go WOT (or anything over a certain load limit). closed loop is your "regular" driving.

changes to the high octane fuel map only effect open loop fueling.

there is no map to change your fueling in closed loop. closed loop is ecu controlled via the car's narrow band front o2 sensor to chase stoich air fuel ratio.

what are you trying to do?

 

I make changes to high octan fuel map but it doesnt make any difference in afr

 

what rom is 52500010? euro ralliart?

what area of the high octane fuel map are you changing?
do you have a wideband? are you logging it?

 

i have a turboed lancer 1.8L, 52500010 is my rom, i have wideband but i don't log my programmer tryed yesterday to change the high octan fuel map but the afr didn't change

 

i change the lamda target in high octane fuel but the afr dosn't change does anyone know to help me? i can post you the xml and my stock hex if you need
