Can someone take a look at my log

[CyberEye]

Need to tune the high throttle points. I have the low throttle points almost perfect for cruising around town. But I just got a new MBC, turned the boost up, and now need to tune the high points for it.

Just ran this log a few minutes ago.
96 Tsi Awd
15psi via S16g
550cc injectors
190Lph pump (rewired)
SAFC II

any help is appreciated. Thanks

Cybereye, your 02's are extremely lean. Your timing is low and there is a strange timing spike at 5808rpm. Max timing on a 2G map is 15-16* provided your intake and coolant temps are in check as well as knock. Did you log excessive counts of knock with this log?

I noticed the O2's saying i'm lean, and the timing's all messed up. I should be running rich with the 550's, I'm bloody confused.


using palm'n'stein to log

umm can't really log knock on a 2g?

Any idea on how's your injector duty cycle?

Yeah, judging by your timing you have some knock going on... try richen it up and go for another run, but to be on the safe side try running 13 or lower PSI check your logger and go from there.

I know my 1g reads .87v O2's when running good, im not 100% sure on your car, but .81v doesn't sound healthy and timing you want to get 18~20 degrees.

What are your high settings at?

I would give it 10% more fuel and try again.

high throttle points are 0 right now. Should I not be running rich with the 550's and the SAFC at 0?

Could the stock fpr being faulty cause these abnormalities?

 

[espinelli]

The stock FPR will not cause a lean condition with a 190LPH pump. If anything it might be overrun causing a rich condition. Check your base fuel pressure for starters.

Yes, 1G's like to run leaner than 2G's. But either way the 02's in this log are way lean and we don't need a WB to tell us that. Since you don't have a wideband your 02's should be around .92-.94v.

But what I'm saying is what if my stock FPR isn't functioning properly?
don't have a way to check the base fuel pressure

Set boost to stock, zero out your AFC and log another run. If everything was installed properly and is functional you should be running pig rich. If not, something is up with your fuel system or you may have a bad 02 sensor.

The SAFC is zero'd out on high throttle points. What could be installed wrong? and the O2 sensor is fairly new, It's running fine under low throttle and getting 25-28 mpg around town. So i highly doubt the O2 sensor is funked

According to your logs your car seems FAR from 'FINE' WTF . You need solid data so we can start ruling things out.

For starters. At what point did your car start running this way and what changed when this started? I can't possibly imagine your MBC being the cause for all this.

Without knowing any facts we could question anything from fuel system, voltage at the pump, crossed universal 02 sensor wiring, air metering etc. BTW are you running a hacked MAS?

Whenever I make a change to the fuel system I always check my base fuel pressure. You should do the same so we can rule out any pump related issue for starters. See if you can borrow a gauge.

that is kinda intresting. Your 190 wont over run the stock FPR. Your 550 on the other hand should be making the AFR run even richer then its stock 9.5:1. but the o2 shows 15% lean conditions. i would cycle your 02 on your palm to see if they are bad. It could be your fpr, or fuel filter.

BTW, Max timing on the 2g ecu at its highest map 2.1g/rev is 17 degrees.

Actually it's 16...

what exactly do you mean by cycle my O2 ? fuel filter is damn near brand new

 

[CanadianTSi]

Watch your o2 value when your car is warm, it should cycle back and forth.
