I have another possible gremlin. This time with flex fuel.
The car:
Turbocharged FA20
FIC 770 cc port injectors
Deatschwerks intank pump
MotoEast Flex Fuel kit on Port Line
The issue:
Looking at all my logs over the past 3 weeks of tuning, I have noticed the Econtent dips at high rpm. It usually starts dipping right at 4500-5500 and comes back up by 7500-8000. I have confirmed this dip by visually watching the ECA during a wot pull. Is this normal? Is this cause for concern.
I followed the install instructions to the letter for the motoeast kit and the ECA definitely works properly otherwise (ie. 91 octane shows E10 and E85 here shows E78-E82 on the display).
The only thing that I can see that may correlate with this dip is PI duty % which starts ramping up at 4,000 rpm. Meaning that the dip only happens when fuel from the gas tank is sent through the PI lines (where the Flex sensor resides). Battery voltage is solid at 14V. Any ideas?
