I am honestly thrown by the prospect of getting this much retard @ 9.9psi. But why would this keep occuring at 9.9psi... because the boost harness wasn't likely calibrated by yours truely.
The MAF GPS, seems a bit low. It is possible that my MAF just crapped out... and isn't seeing quite what it is supposed to. But that doesn't explain the TPS and O2s. Not to mention that the car runs fine, like the MAF is okay. Hmm....
Unless all of the parameters were out of whack from the get-go?
I go do some more "testing" but it 2:45am and wet out...
On my way to studying I saw the knock retard (recorded runs were working in replay, corrupted files I suppose) and decided to bump my fuel pressure 2.5psi to 42.5 total (I have twin pumps and too much FP makes the car run crappy). The boost has been set to ~19psi since some Toulene tests... so I should likely drop it back down to 17psi, due to the cold air and straight Ultra94.
Your TPS indicates you were at less than half throttle. If you were in fact at WOT, I can't trust ANY of the readings you're seeing including boost, and have to get to the bottom of why everything is whacked.
Your MAF readings would be about right for that TPS and level of boost.
So, were you at WOT or not? I don't think you ever really said.
Not being much up on TurboLink, I can't be much help as to why the readings are all low?

...Yeah, I am kinda new at this too... it is just nice to finally have a full time scan tool.
Orlando_87GN, I just put fresh 94 in the tank before I took here out. I wonder if they F'ed up at the pump and put the crappy gas in the good gas tank? Wouldn't surprise me.
I also thought that I may have put my race chip in the ECM during some sort of brain-fart excerise.
If the weather clears up... I'll go for a blast or 11. I'll need a break from my homework.
I know a lot of guys in the club are getting wacked readings with the newer version of T-Link. Most of it is because of EMF. Are you using an inverter? Do you have a battery plugged into the harness? Plugging the battery into the harness seems to really help. Just my 10 cents!
I remember one run down the strip I did, it said I had 30 degrees of knock with 20psi and straight 117 octane. I don't think so! Unless your motor is ready to fall out, your probably getting false knock.

Yeah, I am running a power inverter (no battery thingy). Got it at RadioShack yesterday. I guess that I will be going back to purchase the AA battery case-nota9v-thingy. Funny, I just bought some new rechargeable batteries there yesterday too. Hmmph. I may just have to get the 5 year warranty on the inverter, as well.
As Dave suggested, you were under 1/2 throttle, EGR shoujld have been active and should have helped. Does your EGR work?
Sure nothing mechanical is vibrating at that power level? My DP touches the frame on light accel and my knock gauge goes nuts...just spinning around, to red-start over, to red-start over etc. But anywhere ELSE, its fine. Maybe a possibility?
