recirculator tube unhooked= faster

Your LTFT wont move very much there is a reason it is labeled long term fuel trim and if it is off by 12% then you have an issue but I would drive the car around for a week just to make sure that everything is well settled before making more determinations.

so heres the update i was borrowing the logger and i plugged the hole reset the computer bye taking the battery cable off!! now as im idling with the hole plugged the logger says the stft1: stay at 0 percent the ltft1: stays at 12 percent. the ltft1 never moves even when i am driving but the stft1 goes from -3 to 3 degrees. my timing with the recirculator hole plugged will drop down to -6 degrees only going up hills and the boost goes to 12lbs at 2600rpms. with the recirculator hole unplugged i stay at 7 degrees and boosts to only 5lbs at 2600rpms going up hills. moral of the story with my hole plugged it smells really gasy REALLY GASY and i have like no power but it boosts. with it unplugged it drives completely fine. i have zero boost leaks new 02 sensors though the 02 sensor does react slow on the logger. any ideas if this makes sense to anybody sorry i would of tryed to put the logs up but the palm wont sync with my computer right now.

If your using THAT kind of logger it doesnt support WBO2 its running narrowband.

Is it a MAC or a GENYSIS I have the Gen and it doesnt support wideband readings. If your reading LTFT and STFT only this might explain why your readings are off.


EDIT** Are you running a wideband o2 sensor? I just noticed you said your using a Palm. Which logging program are you running?

it is a palm m100 i am using a program called pocketlogger 0BD2 it has a diagnostics feature and it has a datalogging feature which includes rpm,mph,timing,ltft,stft,engine load,coolant temp,and 02 sensors, and i am just using a stock oem denso replacement, not a wideband 02 sensor.
