    Thread: Installed BFI Stage 2 Chip, ran great for 4 days, now idle problems & rev hang

    1. 10-05-2011 11:50 AM #51
      Yeah ill agree with that...its just the wideband was 300 and I was told thats used more for guys running boost which I don't have(yet)....there's really nothing else I can check or change to make sense of all of this but then again ive always got crappy mileage even before all my mods but no CEL ...I'm guessing the more aggressive tune just made the problem more visible for the ecu?..these are all "maybes" and "ifs" Ofcourse..going out on a limb if u will

    2. 10-05-2011 12:04 PM #52
      Widebands are useful regardless. Its the only accurate way to relay your fueling. You can get an AEM UEGO for under $200 shipped on Ebay. Its right up there in usefulness as your scanner gauge.

      The crappy city, but good hwy mpgs tells me that you closed loop is fine, but once you go into open loop, you have massive issues.

      Have you checked your fueling system yet? Injectors and fuel filter? Almost sounds like a stuck/clogged injector.

    3. 10-05-2011 12:17 PM #53
      New injectors new fuel filter...I thought about swapping in a brand new ecu...haven't pulled that trigger yet tho

    4. 10-05-2011 12:20 PM #54
      New fpr as well...u name it I've changed it...except the ecu like I said

    5. 10-05-2011 12:38 PM #55
      you put in ABA injectors right? (just checking)

      Im stumped. P0172 is related to these in order

      Bad/dirty MAF
      Vacuum leak
      injector issues

      The code trips after you exceed the mazimum percentages adjusted on the short and long term fuel trims. But you replaced everything.

      Have you swapped the stock chip back in to see what happens?

    6. 10-05-2011 12:51 PM #56
      Stock chip=no code but sh*tty city mileage...u think maybe ecu's shot?

    7. 10-05-2011 01:25 PM #57
      No, I think there is something not right with your engine.

    8. 10-05-2011 01:38 PM #58
      Tell me about it...I thought maybe piston rings? How's about I just drop in a Porsche 3.6 engine? Seen a mark3 with one in at h2oi...wow

      Thats just the VW 3.6 V6. Its shared through a lot of platforms.

      So this thread doesnt get derailed any further, my advice to you would be to remove both the vacuum leak device and the PEM. Run the stock chip and diagnose from there. There is something significantly wrong with your motor. Remove the questionable variables and go from there.

      I haven't posted in a liit, but keep giong back and forth through PM's with some of the guys in the thread.

      I've also still got the p0172 code ('98 wolfie 5spd) on the car with the chip installed. I also get the same idle issues, I did adjust my idle down from the ~1050-1100 the chip came set with (did that this weekend). I have it set at ~925, and in order to adjust it I had to modify channel 01, but the others did not cause a change in idle speed. (channels 02-05)

      Looking at the vagcom screen I can see it's saying roughly -7% lambda numbers, I've already tried 2 sets of injectors, 2 maf's, 2 throttle bodies, new upper intake gasket (valve cover and throttle body too), plugs (different gaps and types also) , wires, cap & rotor, fuel filter, fpr, front o2 sensor (rear sensor is currently absent), coolant sensors, new intake elbow, new pcv & grommit, oil pressure sensors, etc. etc. etc.

      I've replaced all the vacuum lines I could find over a period of time, tried 2 different purge valves as well. I'm sure there is more that I've done, but can't think of it all off the top of my head. I've been trying to figure this one out for a very long time now. (I had another thread)

      The car is not as strong as it was when I first put the chip in, I think the full power lasted roughly 1 week after putting the chip in at H2Oi 2010. The idle and weird hesitation got on my nerves at one point that I just went back to stock for quite a while. I've had the chip in for months now, and the full power isn't there that once was. The car doesn't run bad or anything like that, it runs like say stock power or about that, but VERY noticeably lower from the first day I put the chip in. Always running 92-93oct as well.

      @ Travis,

      If you want I can do some logging or supply whatever vagcom data you want if that'll help solve this for us all.

      (I'm also MORE than willing to be a guinea pig for a new flash as well)

      EDIT: I forgot to mention that I also get that random stalling at idle too sometimes (it's been a while though), but it will act like it's about to cut out at the strangest times randomly...actually that part happened again today

      I had the exact same issue with my C2 chip and bbm supercharger setup, I just always figured it was because of the s/c and the position of the throttle body. When I put the throttle body on the intake it would stop doing it. It was exactly how you guys describe it though, random idle hanging/raising between 1-2k rpms when coming to a stop. Never had that problem with early non-c2 chips but they also ran like crap and stalled out constantly, the c2 chip was such a drastic improvement that I never bothered to mention it.

      Good luck figuring this out.

      Weird Update: Just for experimentation purposes, I ran 89 octane today and the car seemed to do actually better for some reason. Power felt like it was there and "almost" no throttle lag. It almost feels like the car has more power with 89 vs 93. Just an experimentation.

      Interesting, are you sure it wasn't just a placebo effect? That would be interesting if it was indeed a noticable difference in dong that.

      I ran lower octane in the winter and never noticed a difference.

      ive got a 98 jetta as well and have the same problem. ive got a 276 cam in there. the random rpms going up and down between 1500 and 2000 untill it eventually settles to 1050. also have a cel for running to rich and im also getting very crappy city mileage, yet amazing highway mileage. i know my maf is bad, kept cleaning it but the code keeps coming back, and i have a brand new vdo brand throttle body. any ideas? i noticed the crappy mileage when i went from my autotech chip to the stage 2 pem. from what i understand, the pem is like a fineley tuned machine that even the smallest kink will throw it off because it demands a lot from all the sensors readings.

      i have been having all these problems that all of you are talking about (P0172,car shutting off during warm up cycle, also while driving )
      the code only came up whenever the chip was installed which is weird..
      anyway, i sent out my ecu and chip over to c2 motorsports so they can check out whats wrong with it.
      once i get an answer from them ill post it up on the thread.. maybe its the same problem for all of us who knows....

      the rev hang is the major issue is it not?

      i think they're all important issues----cant pass inspection with a CEL...engine shutting off is no bueno on warm up or randomly while driving even worse. the rev hang is annoying and the jumpy or bucking throttle at lower rpms is just as frustrating. hopefully we'll get to the bottom of it all soon!
      take the road less travelled...

      I live about 2 hours from BFI in NC. I could drive up there on a Saturday or something if they needed a vehicle with the exact same symptoms we all are having to try and get this resolved.

      Just a quick question, has anyone changed the vacuum lines under their fenders? For the evap system on the left and the vacuum reservoir on the right? I haven't yet cause I haven't taken my fenders off yet. I have changed all other ones under the hood though.
