First logs need help

[AHALLA05]

I just did two logs from my car this after noon and i dont know what to really look for in them if some one could help me out.The first pull was a 4th gear pull at about 10lbs of boost which creeped up to around 15lbs.The second one was a third gear pull at the same boost but creeped up to about 18lbs.The second run is what my car has been doing the past half a year and i never figured out y it was doing it .It felt like it had no power and something was holding it back.All the time while i am just driving the knock will just go up to 43counts and im not even boosting. My mods are s16g turbo, supposedly ported manifold and o2, 3" turbo back, uicp, greddy type s (venting), 255lph,intake filter, hacked maf(honeycomb), hallman boost controller, and the rest is stock here are the logs

Pulled hard the entire 1st run

felt terrible at first then started to seem like it was clearing out and pulled hard but boost went to high so i let off

Log RPM knock and timing, o2 if you want also.

Looks like your car is kncoking terribly with the higher boost so it must be lean, try and keep the boost down until you add more fuel.

 

[AHALLA05]

its not because of too much boost it just does that some times it started off at the begining of the gear with that much knock its just does it i dont know why.then it will run fine 5 minutes later

 

[DSMTalonAWD51]

i dont see any kind of fuel management in your profile. if you have stock injectors jus keep the boost down but if its creeping to 18 from 10 you have a wastegate issue. buy a bigger o2 housing and/or external wg

 

[AHALLA05]

i think my wastegate is bad and ive been told to port my flapper hole. I just wanted to know what was going on with my second log. Thanks for the help though

How long was the engine idling before the second run? If you were just waiting forever and a day in the staging lanes with the engine running, you probably heat soaked the intercooler.

Either way, with a knock count that high, why are you staying on the throttle? If it goes past 20, you gotta abort, man. Save your engine for another run.

 

[AHALLA05]

this wasnt like a drage it was just a pull goin back to my friends house like i said i can just be cruising at 0 boost or some times vac and it will knock up to 43. I dont think it would be heatsoak because it kinda does it when i begin to drive it(start up and go).It just feels like it wants to be stubbern and not go sometimes idk. It just dont like me

Well their are a few things to do.

1: Check your base timing and put it back to 5* advance BTDC. That could be part of the problem

2: Ensure you are getting adiquite fuel. Might want to get a Bolt on FPR and fuel filter if yours is old. Your 255 is also over running yoru stock FPR on the low end until you start boosting around 10 PSI. The bolt on FPR will solve that and you can turn your trims with the FPR as it's adjustable. Your most conserned with the High trim. Ideally you would want all 3 trims around 100% but the High trim is most important for WOT runs.

3: Get at least of used 550 cc injectors and a 2G MAS. The two will kind of cancel each other out as far as the computer is conserned. The S16G will demand more fuel than the stock 450's can provide.

4: And of course check you knock sensor. If the black gooooo has started to ooouuuzzzz out it is time to replace it. I used to have simular issues and I got it taken care of by fixing up my timing tables. But I found my knock sensor had leaked all over the block and replaced it. Now it's not near as sensitive as it used to be.

5: Get a EPROM ECU and learn how to program it or have chips made for you application. This is by far the best thing you can do. I'm useing a EPROM ECU and a EPROM emulator and a laptop to tune with. I can tune the EPROM with the engine running with the laptop. I can see up to 3200 Hz of airflow, No fuel cut. Better timing and fuel tables. ect... And no piggy backs.

That is what I can suggest for you.

That sounds more like phantom knock. Do you have exceptionally loud lifter tick?

 

[Maglin]

Phantom knock is under vacuum not boost. It also is usually something like going from 0 to 43 counts of knock at the same engine speed just cruising. It also has the adverse effect of lowering your octane value and thus your timing. I used to get phantom knock and it is a pain. I used Kyle T.'s phantom knock code and my gas miliage went up and my octane stayed where it is supposed to.

I believe that I am getting phantom knock right now. Whenever I start out in a gear the knock shoots up to 43 counts and then settles back down to 0 after I get a steady rpm. This is all under vacuum, no boost at all. So what is this code you are talking about and will it solve phantom knock? Thanks.

Yes it will. You need to have a EPROM ECU and of course a chip made for your application. Have you looked at your knock sensor to make sure it hasn't leaked out yet? You might think that it's good cause you are seeing knock. But without the goo they become very sensitive. The engine harmonics will be enough to set it off thus why it's called phantom knock.
