2016 Camaro SS E Force Supercharged Issue

2 Attachment(s)

Cold start is really bad here. E Force Supercharger. Car has been to multiple shops and cannot be figured out(including dealerships). Shop here that has it asked if I could try to help them out. I downloaded a stock tune from the repository and it seems like the tune on this really isn't much different than stock. Anyone with one of these chargers on their car or has tuned one have a look at this? Seems to aim extremely rich at start up and the number 1 O2 goes extremely lean. Maybe a bad O2? Before I go suggesting parts be thrown at this thing maybe someone has seen something similar. I named the file stock when I grabbed it off the car but I'm assuming its the EForce file. Car was bought from a dealership with the charger already installed. Customer knows absolutely nothing about the install. I did not even attempt to take it out. It would barely move in the bay when I triedAttachment 108109 Attachment 108110

I do a lot of these, if I get a moment I’ll look!!

Thanks Ben, I do see where the insane Lambda is coming from at start up. The cranking EQ seems nuts to me, but a stock tune is the same. To have the commanded EQ we are seeing the fuel rail pressure is really low in the table. I honestly don't know if this is normal, or if there is an issue with the pressure here. This commanded EQ and the #1 O2 sensor readings has me stumped bud.
