could be a heap of things
bad MAP sensor settings in tune if your running aftermarket MAP sensor
faulty maf or map
intake leak boost leak ect.
did you clamp off hoses under intake manifold one might have blown off under boost.
around 3000 rpm is where your getting the knock up yo -5 degrees correction will cause some hesitation as ecu pulls timing and this is with Advance multiplier at 0.3 (it should be one) so ecu has already removed quite a bit of timing.
The Stock 02 sensor scaling does not read AFR richer than about 11.25, so without a wideband you cannot tell the actual afr your running. Boosted cars will run richer than 11.25, but stock sensor will not measure that.
you need to talk to your tuner about those issues.
all that stuff could be rersult of faulty sensor or air/boost leak |
I really appreciate the help here. During test drive number 1 I blew off one of the pcv hoses under the intake manifold. I then clamped the 3 under the intake manifold and 1 other by the oil filter. The long file with CEL was test run #2, and the short file is test #3. I have double checked all clamps and connections for obvious leaks. I have requested the tuner check over the logs and will have a revision by Wednesday I believe. I am new to the boosted scene and panic easily lol sitting on the side of an expressway today wasn't that fun. Looks like I need gauges sooner than I thought.
Thank you again Steve99
