Hi, is there any chance to tune the open loop maps,on a 2011 STI, leaner than 14.7?
Of course just in low loads,where from the factory it comes with 14.7.
I would like to set for example 15 or 15.5 just to save fuel during daily driving at low speed.
With Ecuflash I have seen that with the EVO is possible.
Some of you guys has got a solution for this?
