Tuning

[Anduinlight]

Alright so i just bought a data cable so i can use my palm based data logger,
it's a direct into diagnostic plug thing with my palm m105 using mmcd
my questions is what values am i looking for as far as knock and injector pulse and things like that go
I have a 92 AWD small 16g turbo, gm maf and translator in pull though setup, 550 injectors and thats about it as far as mods go...
just wondering what i should be looking for
I'll post up som values that i'm getting later, but just wondering what to look for

alright one 3rd gear pull
from 4406 rpm-6781 rpm
99.6 %throttle the whole way through
knock 30-15
o2-R .07v-.01v
timing 5 degees-8 degrees (somwhere in there i hit 9 degrees of timing)
injd 58.5%-102.3%

a little bit better picture

you need to de-knockify

[Anduinlight]

alright..... how do i do that???

add more fuel or turn down the boost.

and rev to 7500. start with low boost(10psi) and to much fuel then up the boost a little and take out a little fuel, etc untill you find what works best.

Do u have a fuel pump? Looks like u are running out of fuel supply which leads to lean, which leads to knock, which leads to no timing...etc.
Fuel pump upgrade?
Throttle should read 100% on wot pull, make sure there is nothing behind your gas pedal, then check your throttle cable to make sure your opening all the way, lastly adjust your tps sensor.

The knock amount, coupled with the low 02 readings and the lack of timing makes me think your running rich. It could be fuel delivery, could be the tune (to much a/f signal being seen/being taken away) couldn't tell ya without more info.

About IPW's, I personally don't like seeing them about 90% duty cycle. Of that percentage for a constant demand is a good way to have one fail on you. I have run 110% duty cycle on vehicles, but the injectors don't like it, the car runs like poo, and its just generally bad. Either your way to rich (maf-t setting, what are your afc settings?) or actually running out of fuel.
550's should be good on a 16g..so maybe it goes back to that fuel delivery issue...
If you could list more information, that would be great.
