new logs, plus fuel upgrade time!

[venomhiss]

well in true DSM fashion, i switched my stock MAF back on and made a datalog run, and VOLA! the knock is gone.but my injector duty goes WAY up there...so im upgrading my fuel pump to my 255lph and m AFPR today as ive had them sitting for a while.

take a look at my logs and tell me what you see that looks strange, my air intake temp came back too....weird. coolant sensor is still shot. thanks

please guys, i am losing it with this car

whoa man your getting a lot of knock that could be fatal on your mototr in the long run! Your running hot and the ecu's gonna pull timing anything over 203 i think. I would suggest putting the maft (if thats what you had on it) back on it and taking a look at this site. http://www.jeffgst.com/index.html
its helped me a ton.

No wideband?

Bring the 5,500 rpm timing slider down 2*. Bring the 6,000 rpm timing slider down 5*. That MIGHT get rid of the knock.

What was your boost guage reading?

The gm maf has set values that don't change for the intake and baro inputs. That is probably what was doing what you mentioned about the intake temp. That is also why you need to ignore iat/baro when using a gm maf. You do this by going under the miscellaneous section of dsmlink.

You need to stop doing pulls until you get your fuel supply issue fixed.

Based off the o2 voltage your air/fuel ratio is pretty lean for pump gas. This is part of the reason it is knocking.

You really just need to fix the fuel problem and then post another log. And you should get a wideband if you don't have one.

Only 2G's pull timing due to coolant temps. Both 1G and 2G pull timing due to intake temps though.

boost gauge hit 15psi. but i need to find the boost leak as well since i managed to get it to hit that perfectly, anything over, and it does not hold. this was just to see what you all thought of my most recent trouble filled log. thank you

Is your maf hacked? If not, you have a leak between the maf and the turbo that is letting unmetered air into the engine. Look at your boostest at about the 5,500 rpm range. Boostest should match your actual boost from 5,000-6,000rpm's. Since it is reading lower than actual boost this indicates the leak I mentioned.

my MAF is stock now, just the 1g with no hack. and i think i can figure out where that leak is coming from too. recirculation tube easily. could this tube be my boost leak? o would it be after the turbo? i know i coul dhave more then one as well (damn it)

The recirculation tube is deffinately a possible cause of the leak I am talking about.
