First, super new to tuning and the likes. Not new to automotive though.
Now what is the purpose of fords map sensor in conjunction with a maf? I'm in the process of building a 2.5 ford duratec from a 2015 fusion. Im using the factory ecm with hptuners. I've added a turbo and moved maf to blow through. I know that these maf don't like blow through but expected map to do something. Watching the data, the maf does nothing. The iat are over 200 degrees F and at about 1300rpm car starts to stumble and go lean, via wideband. And help? Haha..
