DSMLINK log: running real rich under boost... robbing power? help.

[quik4g63]

okay i've been running very rich under boost for safety sake.
my wideband is showing 10:1 flat under boost. i think its richer than that.
i was wondering if someone could look at my log and tell me if running this rich is hurting my performance?
the car feels quick but i did a hard pull to 100 mph and the log shows otherwise. (running 15 psi on gauge)
could you share with me what you think?
any tips or suggestions?
i think since there is almost NO knock, the tune must be okay...
just dont think im making the power i should be making... IMO
thanks for your help...

If your wideband says your rich lean it out some. Try 11.1 a/r. Why are you adding so much fuel if your running rich?
Your not doing yourself any good running that rich thats way past the safe zone.

your boostest is pretty close so I would just start leaning it out a little at a time. With those injectors you should be safe at or around 18 lbs. without overdriving them. Your not even gonna scratch the surface of the power you should be making with that size turbo at 15lbs.!

+1, if its stuck at 10.1 all the way up, then definately lean it up a little. Slowly but surely.

Have you posted in the link forums to get any help?

I suggest that when you lean it out you first fix your timing curve.

You need to look at the 1g estimates at the bottom of the "timing adjustment" window and make it more consistent. The 19* at 4500 & 5000 is good, but you will need to pull 5500 & 6000 down to 19* since they are at 21 & 23 right now. Don't try and make your sliders smooth, make your 1g estimates smooth. You can shoot for higher peak timing once you get your AFR closer to 11:1 if you're not knocking.

The fuel you have added from 4-5k isn't necessary since you don't hit full boost until ~ 5300. I have found that pulling a little timing at the full boost mark works better than adding fuel.

You are near 90% IDC with that AFR. When you lean it out you will be closer to 80% and can run a little more boost before you run out of inj. But they are too small for that turbo and high boost.

You need to do a 3rd gear pull. Get to a highway on ramp and do a 3rd gear pull from about 3k rpm to redline. That log will be much more helpful.

The t-67 is not gonna make enough power at 15psi to make you happy. My 14b was getting the same 70-90 time as you at 17-18 psi.

You need to calibrate your GM MAS. You are about 6% off, but I don't know which HZ slider to adjust b/c you need to log MAFRaw. Go to Jeffgst.com to see how I got that number.

Where can I buy DSMLink. It seems everywhere I search ECMlink is what comes up. Not to sound like a noob but are they the same thing? That's what I'm assuming but would like to know if I am wrong.

Ecmlink is the newer software and is the one you want.
