i am new to it, and i discovered i had a bad o2 sensor so i replaced it and when i started datalogging again it was abnormal so i had a few questions

my o2 volts were .98 or above(1.06 highest) which i know is really rich, so i leaned it out 3% across the board and bumped the boost up to 13 psi(was 10.5) and logged it again and the lowest i saw was 1.00 so it got richer with more boost and less fuel :confused: and this time i logged my timing too, and i saw it hit 0 degrees at 1.02 at 4k rpm i have to hot of a plug in but still i was running 91 octane still. is this all because of the plugs or what?

could someone give me a link to a program for extracting(or what ever its called) datalogs so i can post them on the internet. i use the pocketlogger software.

do you think i got shitty gas the plugs a bad knock sensor??? i don't know what to do

my important mods are turbo back exhaust 16g 190lph fp hks super afr(like a safc) and that about all i can think of to affect tuning really
 
Are the O2 readings you're talking about @ WOT? If so and you've done most of your tuning on the bad O2 sensor, I'd personally go back to 'stock-ish' settings and restart.
 
i had the throttle smashed, my tps sensor only read 99% throttle... would that do it?

i never tried to tune it on the bad o2 sensor. i just got my datalogger setup like 2 weeks ago and a day later when i had time to use it i noticed my o2 sensor read .16 v at highest so i replaced it after checking it with a multimeter, just got my new one from oxygensensors.com(BY FAR THE BEST PRICE!!, and 2 day free shipping) and put it in and i decided to do a log and i was like wow thats rich and assumed my timing should be fine then i leaned it out to -1% on all settings and logged again with timing on and it was shit

anyone have a program that will take a log off my datalogger so i can post it on here?
 
i would also like to ask what should me tps read at idle? its reading 2% i just replaced it so i thought it might be a little off, i adjusted it according to feel my multimeter wasn't with me and i didn't have a datalogger
