2-3K RPM hesitation/bucking - logged
Hey guys,
Wondering if anyone with some experience looking at logs and tell me what they think about my log file. After installing a S/C kit I'm getting part throttle low RPM hesitation/bucking. Even full throttle has hesitation in the same RPM range too actually. I purposely drove up a slight incline and in a lower gear to help the log show what was happening in a longer period of time. Notice at about 9 and 11sec the vehicle speed slows, then speeds back up slightly, this is when I was experiencing the hesitation/bucking. All other load points feel smooth. The calibration used is a CARB tune provided by the manufacturer. http://www.datazap.me/u/86fun/low-rp...ta=2-3-4-5-6-7 Thanks for any input! |

Looks like some sort of failsafe trip or something in tune, but this might be caused by malfunctioning sensor or air\boost leak. Send logs to tuner |

Knock looks like it may be another concern. What fuel are you using? |

I did not have this issue when on factory CARB tune from Edelbrock.
