something has happened to the tune MAJORLY!![DOUBLEPOST=1412028948][/DOUBLEPOST]You need to add open and closed loop to your logs.. also at those coolant temps the engine should be in closed loop meaning the o2 sensor should be cycling from what I see there is no o2 cycle also don't see any fuel trim info whatsoever.. mafraw no info and also the airflow per rev is not showing anything at all... Do you know what your looking at? or how to fix any of this?[DOUBLEPOST=1412029499][/DOUBLEPOST]The tune is not at all fine... with the data that you have posted in the log. something has happened possibly could be the ecu or ecmlink itself. I can walk you threw some steps to try to find out whats going on possibly... But you may be up the creek without a paddle from what im seeing... im no pro tuner and do not claim to be,but I however do know somewhat of what im looking at and the main concepts and functionality of ecmlink. Any check engine lite on? What kind of air metering are you using 1g 2g evo mas gm3in or speed density setup??[DOUBLEPOST=1412029954][/DOUBLEPOST]Also I notice that the int temp is -71 degrees leads me to believe air metering is the culprit. check your plugs for the maf check for broken wires there should be a cel in ecmlink if there is an issue there. Also no airflow no maf signal your issue lies there somewhere my friend do some looking around and get back to me

Have you pulled the ecu and checked for a burnt ground trace? The -71 intake temp makes me suspicious of the ecu.

-71 is what the ecu defaults to if the IAT sensor is bad fyi. Check your sensors wires and replace.
