One more and that's it for now.

Here's a link to the complete TMO Log. So if you have TMO ... you can view this: http://benji99.homestead.com/files/BadTestLog.tlg

You should also check out this huge log pic: http://benji99.homestead.com/files/LongLog.jpg

Or download the complete log as an excel spreadsheet: http://benji99.homestead.com/files/BadTestLog.xls

91 GSX. 190LPH, Ported 14B and o2 housing, MAF-T 1.3, Blow through, 3" GM MAF, Stock SMIC, Stock Injectors.

At WOT or even mild acceleration, the o2 Voltage drops between 0.00 to 0.08V. Weird thing is that there is hardly any knock, timing is between 18-22 degrees most of the time at WOT. The is bucking horribly at this point.

Starting problems are also present. It's worse after you drive it for a while, shut it off and restart it. I have to prime it for 20-30 seconds. Sometimes it will not even run at all and immediately die numerous times.

Changed the ECU, plugs, wires, Coilpack, MAF-T, o2 Sensor.

Running 14lbs of boost. I am currently not able to see more than 8 or so as the car pops and stutters too much.

The O2 sensor seems to be cycling normal under cruise conditions as well at idle once warmed up. The car feels like someone is stepping on the brakes even at cruise occasionally.

The idle log was taken after about 15 minutes of driving so the car was warmed up fully.

The settings I had when I took these logs were:

Base: E +10%
Idle: 2 +10%
Mid: 8 +35%
WOT: 8 +35%

Then later I changed the settings to: (some of the logs are after the change of settings)

Base: 0
Idle: 0
Mid: 0
WOT: 0

No difference, it's actually worse when I zero'd it out.

OK, I don't know much about the MAFT set-up. To me it looks like you could still have a bad O2 sensor. Did you get one from the dealer?

Also, timing is getting pulled for some reason, but you have no knock.

Are you sure that the MAFT is hooked up right? The graph shows very little Karmen at WOT, which seems wierd, but like I said, I don't know much about the blow through.

If I had to take a wild guess, I would say that you were dead lean. On the WOT log, when you got a injecter p/w spike, the O2's spiked up a little. Being dead lean will cause no power like you were saying. Are you still on the factory fuel system? I would check/replace/clean the fuel filter as a start. It's getting enough fuel at cruising, but at higher fuel demands, it drops off. How does the fuel pressure look? Does it drop off at all? Bad o-ring at the fuel pump? Bad fuel pump? Clogged lines or filter?

This would not explain the lack of knock, but I've seen some weird things going on with some cars.

Try richening it up pig rich to where you're blowing black puffs (not clouds). Does it change at all? You may just have to change your MAFT settings.

Just throwing a few ideas out there.

Except for the Walbro 190lph pump, the fuel system is stock. I did change the fuel filter already. I have the MAF-T set as rih as it gets (settings:E, 8, 8, 8 - I believe) with no change.

Thanks for the help ...

[project94tsi]

from what i have learned so far about tuning it looks like you o2 sensor is failing, replace it and see what happens.

[psychlow]

I'm experiencing the same type of problems, excepting the fact that at any time I'm WOT, I immediately get 43 counts of knock.

If you coast downhill in 1st with no throttle, does it buck like crazy?
