The car is in speed density mode, it doesn't even have a maf. The LTFT's are enabled, but I must be forgetting to do something for logging because when I take the car out, the fuel trim histogram shows up 0 in all the cells... As great as that would be, I know for a fact the car is running quite lean. What am I forgetting or not doing right? What exactly do I need to change to get it to read the fuel trims?
