some weird stuff going on. logs inside

dirtmaster666 · 09-01-2012, 12:16 AM

hey guys. my car has recently been doing some really weird stuff. i am full bolt on with procede rev 3 running 5.23 aggressive stage 3 and was having no issues at first. So i have my gages high jacked for boost and afr and sometimes just sitting at a set of lights my afr will go from idling at about 15 or 14 to 1 to all of a sudden jumping to at least 21:1, and so when i leave the light, driving completely normal using very little boost, maybe 3 psi it sounds like it pulls timing and and starts detonating. then after a bit of driving my afr jumps back to 15/14:1 and i can run full boost no problems... i took a log to see what is happening when i get this detonaton feeling and the first log shows this but i dont know what to do to maybe help this problem. so i drove back home and when i parked i let it idle for a bit and now it sounds like i am getting a big miss when idling. so the second log is obv just stitting at idle. in both logs my open loop is also set to 100%. and aslo am getting no codes.

can someone please help me out with these logs? i dont know whats going on.

Make sure you turn CANClear off, so you can actually see if you are throwing codes, my bet is you are.

Sounds like something went bad since it was sudden change, Spark Plugs, Coils or Fuel Injectors would be the best guesses.

dirtmaster666 · 09-01-2012, 12:33 AM

ya i forgot to turn canclear off. i take a peak and updaste if codes are present

dirtmaster666 · 09-01-2012, 02:26 AM

so the codes i got are 10740 and 10741- catalytic converter ineffiency 1/2

should i lower my o2 modifier value or are these codes to do with my cattless dp? (i would assume the latter)

also went for a cruise to further investigate and so i changed to the stage 1 aggressive maps and i am still getting detonation even though i am FBO. one thing i dont have is meth though... any thoughts?

dirtmaster666 · 09-01-2012, 02:28 AM

even just on light throttle it definitely feels like a "miss" or sputter if you will but i am not throwing missfire codes. does it take a few days for the missfire codes to show up?

drewmeyer87 · 09-01-2012, 04:15 AM

Usually there is a certain threshold before a code is thrown, but it's usually pretty quick. For instance, my friend had a bad coil, the car was sputtering and misfiring on start, sitting there idling - no code was thrown, but the second you gave it some gas, ding - there was the code.

If you are getting intermittent sputtering or what seems like a misfire, my first question would be, when was the last time the spark plugs were replaced?

Problem without codes is it's hard to give any recommendations without hearing/feeling it actually happen. The codes you are seeing are DP codes, they wouldn't be causing you any physical trouble.

dirtmaster666 · 09-01-2012, 11:29 AM

The cars has got 66000 km on it. Maybe it's time for coil and plug replacement?

drewmeyer87 · 09-01-2012, 12:58 PM

I would say you are due for some new plugs. It's a cheap job to do yourself if you are not under warranty, just need the special socket for it from BMS or elsewhere.

If that does not fix it, I would look at your intake valves and see if they are caked with carbon deposits. That would likely cause some of your issues and not necessarily throw any codes.

Justin lmk if you're gonna do a plug change I have a spare socket you can use

That would be awesome. After driving around I finally managed to get 10701 which is misfire on cylinder 1. So I guess I will start with plugs and try coils if that doesn't work

Rob.K · 09-02-2012, 03:40 AM

I had the same issue cept on Cyl 5. Changed plugs and problem was solved

You just get plugs from dealer or somewhere else? What are they worth?
