First, let me say this forum is dead..... I'm not feelin the love for the Utec anymore.

Ok, back on point. Do NOT try to scale injectors without knowing what your short term and long term fuel trims are doing. There goes a wasted week of trying to build a fuel map....

Get a method to monitor these two vital outputs before injector scaling, or you're just pissin in the wind. You might get lucky, even a broke clock is right twice a day.

 

Hi. Are you talking about the 2 parameters in the open loop fueling screen??
