Finally Got The Car Logged, Not Good?

[tsidrift1]

I finally got a datalogger and ran some logs. My car has been running like complete ass lately. Anyway, I havnt figured out how to transfer the logs yet, but I know I am getting knock and some other messed up readings. At 3250 RPMs, I am at 43 counts of knock!, Timing is 22 deg. ,tps is 24.6%, I am new to this stuff so I thought i would throw a few things out there and see what you guys think. Let m know if there is anything else I should be looking for.

 

[justin0469]

do you have anything to tune with? safc or dsmlink or anything?

 

[tsidrift1]

No not yet I will be getting the maft thought when I do the blow thru setup.

Since you have no tuning method, I assume you are at stock boost.


The logish info you posted... 3.2K RPM 22 deg timing, TPS @ 24.6%, was that at WOT? If so, check your TPS voltage. It shold be 100% at WOT in the logger. Or, are you saying at 24.5% throttle you have silly amounts of knock?

 

[tsidrift1]

I dont want to sound like a #### or anything, but my engine has just about 200,000 miles on it and I cant keep my drivers side intercooler pipes from blowing off. So, yeas that is probably at around 25% throttle. I am just a little cautious right now with the car. I just have payed attention to the knock mostly cause my car has been running like ass and I have been reading about knock. When i got the logger hooked up and saw the knock, thats what mainly I am concerned with right now. I am still new at this stuff, so it will take some time to get used to reading the fule trims and all that stuff. I have a manual boost controller with and a boost gueage. the few times I have realy punched it it can hit almost 18lbs of boost. So I dont think I am running stock boost. It kinda boosts to were it wants to right now. I am really looking for a sample log of a 1g to see what some of these readings are supposed to be set at, at different rpms. I know when I downloaded the mmcd program from that site, I think it is www.mmcd.com/sourceforge.net, I looked at the sample logs there, and my car was showing lower readings in every catagory than that sample log it was showing.

 

[justin0469]

do you have stock turbo? in your profile it says b16g coming soon but i dont know how old that is. investigating why the boost controller isnt working and getting your piping to stay together could magically solve the issues you are having. exactly which part keeps blowing off?

 

[Omega]

Well, 18PSI with no supporting mods won't extend the life of your 200K mile engine

Get your MBC sorted out and lower the boost to where you don't blow the pipes off. I would suggest bypassing it. Go straight from the compressor housing (or IC pipe) to the wastegate. That will get the boost undercontrol or reveil other problems.

So, you are saying you have part throttle knock. Have you done plugs and wires recently?

With that amount of milage, I would suggest changing the knock sensor and working from there.

I wasn't being an ass... and quite frankly I couldn't find a nasty comment in your reply

 

[tsidrift1]

I dont have the big 16g yet. The piping is blowing off right were there is a 180 bend going from the front mount to the j pipe. It is two 90s put together to get around the frame and into the bay. I can actually here the damn pipes leak when i start to hit boost.

 

[tsidrift1]

I actually was meaning to say that I am kinda scared to get on it too much cause it has so many miles on it.

 

[justin0469]

since boost leak can most definately make your car run like crap, i would fix that and it very well could take care of the rest of your issues, or the majority of it. i cant quite picture what you are talking about but im sure if you have common sense that you can figure out how to hold it together. to make your life alot easier, build a boost leak tester so you can tell exactly where the leak is coming from while you are working.

[tsidrift1]

I have some mods on the car. I have full 2.5 in exhaust front mount with 2.5 in aluminum pipes, I have a k&n filter if that matters. not much but a few little goodies I have the gm maf now and am waiting to get a translator, and I want to upgrade my turbo to a evo big 16g this winter. I dont know if you guys have seen my past threads, but my car has recently started smoking too, its not the rings or headgasket i dont think cause the compression is still good on the old bag. i am thinking it is my valve seals.

 

[tsidrift1]

Me and my buddy tested the pipes the weekend we installed it. We pushed them to 20psi and heard nothing. I think what happens is as the car warms up and the pipes warm up the few rubber couplers I have expand and start to leak. I need to replace the rubber ones with the blue harder rubber type ones. We had some sizing issues so we had to resort to the rubber ones.

 

[justin0469]

maybe they got knocked loose or became loose after prolonged exposure to boost pressure. to be on the safe side test it now and maybe you will discover other boost leaks you dont even know about

 

[BudmannG]

I can't get the link to work that you gave for the mmcd logger. I just got mine in yesterday and was wanting to check things out before I get to far into it.

 

[tsidrift1]

That link probably wont work, I knew that wasnt the exact website. If you search on the forums and type in mmcd, you will find a lin somewhere for the page. It is similar to what I said it was. It is a yello page and when you scroll to the bottom it will have some oics of a logger setup with the mmcd running.

 

[justin0469]

probably meant this
http://mmcdtools.sourceforge.net/
heres others
http://www.ecimulti.org/mmcd/
http://mmcdlogger.sourceforge.net/

 

[tsidrift1]

There ya go. Justin got it for you

 

[caz]

Just fyi...
43 counts is the max it will pick up. I would probably bet it's phantom knock.
Anyhow, you don't need to be running 18 psi without proper tuning and fuel...
Turn down the boost, replace wires/plugs, check motor mounts, boost leak test again, etc. etc.

Here is a sample log from mine. Not anything close to stock and it was a 2nd, 3rd, and into 4th.
