Post a data log.
Best guess is you have an air leak , either on the induction or exhaust side.
Post your latest tune.

from the log:
* during the WOT your STFT is -14%, seems to me like you have to tune the MAF a little better?

First of all, congrats on getting it to start.
Please explain here what you fixed to get it to work so that others can learn from your work. (at least i would like to know)
Why did you change...
Explain How you fixed it here so that others can learn as well.
twistedtx,
so your table 33486, do not push this above 95, if you have a stock turbo , this table should be close to stock values.
things are not really making sense to me in your latest...
I had the same problem with cold starts.
Here's the advice i got from this forum and it worked for me.

You need to make a better channel list (of signals you are recording) like we talked about before.
from the datalog, it is showing that the injectors are turning on while cranking. How are you...
i think it would help to record some extra turbo-related channels, like wastegate dutycycle, desired pressure ratio or boost , measured pressure ratio or boost.
During your first WOT:
I noticed...
Please post a full list of all your DTCs (diagnostic trouble code)
It wouldn?t worry me if you see 12v at the injector pin. The Ecm is very likely using ?low side drivers? to enable the injectors. A low side driver can look like 12v when the driver is off. It turns...

you need to record a better list of variables, we can walk you through it how to add more signals to record. a few variables you're missing, the pressure and temperature pre-throttle body, injector...
Yes, put your car in ?run, engine off? , then start scanning, then crank while it?s recording. Whenever ur done, click stop scanning, then go to file>> save recording.
Post it here and we will...

i'm not sure if it would be theoretically better to put it by the OBD connector or the TCM. Honestly your harness should be so short it shouldn't really matter as long as you have the right...
Yes, you still need the PCM connected to the TCM through GMLAN.
I think you can connect the OBD connector either way, either splicing a "T" into the wires, or i think you can also use the 2 pins in...
hey Ghost, sent you a PM.
