Hello all. I have a honda civic ep3 type r (europian model) with k20a2 forged internal and rotrex. I am running kpro v4. I tuned the car in open loop and it is ok now i make it closed loop and everything works fine and the trims is between -5% and 5%. The only problem is that when it is warm and at idle the afrcmd it goes always to 14.7:1 and i want it little bit richer. I have change in the target lamda low speed the first cells that the ecu uses for idle to 13.7 but the afrcmd goes always to 14.7. What i am doing wrong? The idle afr is adjusting from somewhere else? thank you

In the idle parameters, have you changed the idle target lambda?

in the PRA model the target lamda at idle settings is always grey and shows 7.35 and you cannot change it. But i was playing with the parameters and i findout that the target lamda maps for the idle is working only when in the closed loop advance settings i enable the "enable target lamda tables" if i dont the closed loop is working but at idle it goes always at 14.7. So problem solved, thank you for your time. But now i have another question for anyone that knows. Lets say i am driving the car and the long time fuel bank goes to -2%, when i push the throtle down and go at wot the closed loop stops working but the fuel maps keep the -2% trim from closed loop or is the maps without trim?
