F&F Stage III 47lb turbo
Returnline
AGP WGA,
Snow Performance Stage II Meth/inj
11.40@125mph 26psi and no boost leak
371whp @22 psi pump gas ( With a big ass boost leak)
i just finished installing PTP's SST. i took it for a test drive at around 20 - 21 pounds of boost bc thats what the uncrushed dsm bov is letting me do. thing pulls hard as hell. it was awsome. I was getting some KR however. AFR were 10.2 - 10.5 (havnt started to tune yet) KR was at 6.5* at 5,100 rpms. IAT's were 66*. I was reading through this KR sticky and read that the stock or staged pcm are set for stock turbos and run alot of timing up top bc (a.) the stock turbo dosnt push alot of air and (b.) boost falls off meaning those 2 combined means lower cylinder pressure. therefore it can do higher timing w/o KR. now since i have the ptp's fuel tuning module clamping, the pcm sees less boost therefore adds even more timing. Since putting the SST on it is pushing MUCH more air into the cylinders creating much higher cylinder pressures, added with the fact that the SST dosnt drop boost up top like the stocker, and that the PCM is seeing less boost b/c of the FTM, would make the PCM want to run higher timing like 30* perhaps, when in actuallity the car wants to run lets say 23* of timing. So i think the car is knocking bc the pcm is advancing the timing too much up top, b/c of all the factors listed above. i still have my msd dis-2 unit on my desk, and i will try to install it back in tomarrow or later on this week, bc it has a nice feature that allows you to retard timing b/w 0* and 15* starting at a certain rpm. im going to set it up to pull 5* of timing starting at 4000rpms and log KR next to ignition timing w/ my aeroforce gauge and see if that solves the problem. let me know your thought on this, and i will keep you all posted when i get some results.

I see knock at 10psi and still see 6-8 counts of knock to redline on my aeroforce guage. I have a 50/50 water injection mixture and am running 93 octane with all supporting mods. I also have stage 2 pcm so that may have something to do with it. I dont know what the timing is at...was paying more attention to the knock. When I get my clutch situation figured out I will be able to do more...like changing the meth/water mixture, turning boost down, etc. I heard a few degrees ok knock is ok, but over 8 is where yuo need to let off. What I am really wondering is why do I see like 5 degrees of knock at only 10psi. My first nozzle for water/meth kicks on at 7psi and the second comes on at 17.

What are your other mods??
Piggyback?
how much are you pulling?
Knock sensor going bad maybe?
The Aeroforce dosent ready timing really, that sucks :0)
Have you flow checked your w/i? you should not be getting any KR at 10psi what are the temps were you live? really really cold or no?

The areoforce gauge does show timing, total advance and knock retard both in degrees. I had the same problem, wasnt that high of knock count but now that i have my W.I. it went away, also alowed me to turn my map clamp down some. My boost is in my sig and it runs strong as hell now. AFR's still droping into the 10's by redline but I need to do a boost leak some time soon.

The Aeroforce doesn't read timing? What do you mean by that? It reads base timing, spark adjust, total advance, knock retard in degrees, and knock sensor voltage. What is it missing that you want to see?

Dude its just my bad e-grammer (NOTE the "really") there should have been a question mark "?" and a coma, I was saying: 'it does not ready timing? really?' as in: Just asking!
thought id brake it down really, really good.. Now you know what I ment
from OTHER GUYS POST: "I dont know what the timing is at..." read a few posts up

my w/i might have been contibuting to my KR for a while actually. i had the nozzle right in the middle of the bottom 90* bend and did not have a catch can or a check valve. so all the oil that collected there was clogging the nozzle just enough so that it was not a fine mist but a stream or water. so when that entered the cylinders it could have been causing some of the KR. i still havnt installe the msd. but i have installed a new FPR w/o the PTP 80 psi FPR mod and put in a set of PTPs 650 cc injectors. ill let you guys know if the injectors helped at all tomarrow.

Not sure on the timing...I was concentrating more on the knock.
Knock sensor going bad maybe?
Not sure, but when I get the car back on the road I will be dumping some high octane in the car to see what happens.
The car is on a lift while I await a new clutch and flywheel from CM to come in. Once the new stuff comes in and I am able to break it in I will put some race gas in the car to see if I still get knock. It very well could be a bad knock sensor, but I didnt get any knock at all before. I had the stage 2 injectors in the car....was running 17.5psi to redline with 27-28 degrees of timing and no knock. I went ahead and put the 750cc injectors in the car and started tuning. Ended up so far with pullnig 26% of my fuel out globally and adjusting the map...needs more tuning of coarse, but thats where I am at.

by pulling 26% globally you are lowering the amount of boost that the pcm can see and therefore increasing timing. high timing w/ a bigger turbo is going to give knock.
