Didn’t want to remove my chip so often, so I plugged in my Emulator, all of a sudden engine runs lean. I thought at first it could be a leak but I couldn’t anything.
AFR was about 14.0 now 19-21 AFR, on both banks since I have two wide bands.
MAP idle vacuum didn't change, it's about the same as before 62-65 MAP.
Fuel pressure is 44 psi
TPS .57 volts
Running open loop
Removed the Emulator and put in my last chip, same thing again, AFR way to high. I even tried much older chips. So I finally enriched the mixture to about 14.0 again and haven't noticed any problems since.
VE idle table value was 38.2 now about 42.5
All the way across the VE table up to 7000 rpm I had to add about 8-10%
What could have caused this??
