Hey guys. Looking for some help. Tune and Log attached.
I have a 2002 c5z06. I am currently experiencing a P0103 error and reduced engine power. When this error occurs the is the car now in SD mode? I believe the P0103 is due the MAF freq set to 0 and to MIL of first error, by why does it enter reduced engine power mode? When it goes into reduced engine power it revs up to about 2800rpm. This can been seen when rolling in the log at 1min and when stopped in the log at from 1:40 to 2:00. Is the high rpm due to airflow values in the tune wrong or a effect of the reduced engine power mode?
Previously the car was going into a full lean condition when WOT. Where my wide-band would read ~22:1 and the narrow band would read ~0.050mv. These issues started with the addition of ID1000 injectors, a fast 102 intake, and a NW102 TB. At the advise of members I updated my original tune such that:
Engine Diag- Airflow - P0121 Max 100KPa
Engine Diag- Airflow - P0121 Min 0 KPa
Engine Diag- DTC - P0101, 102, 103 to MIL on First Error
The car will idle and drive (obv needs tune work) briefly until it triggers into reduced engine power mode. I only have a few short trips on the setup as I cannot go WOT. Something must be wrong. What am I missing?
Any thoughts and suggests would be appreciated.
