2006 Tahoe with a BTR Stage 2 NSR cam that I am trying to get the BRAF dialed in. From Start Up (81 degrees) to about 130 degrees, I'm having a hard time figuring out what is wrong. Cold start is 81 degrees cause I'm in Texas. Things that seem out of place:
- Spark Timing
- O2B1S1 & 02B2S1
- Desired RPM (commanding 905 but shows 1175)
- STIT
I logged the desired idle air against the ECT and from 90-degree column to the 111 column, and the airflow is very high when compared to the rest of the ECT columns. Does this seem normal? Any info and help is greatly appreciated. Log File and Tune posted below.
