  1. Gotcha. Thanks Mike. I'll start digging for the needle.
  2. False readings not flash readings*
  3. You guys made me remember some things I have checked with varying success. Right now it seems like what caused my misfire code it a tune or sensor issue. The longer I run any one tune it seems like the stutter gets worse. Until the day I got the misfire code, I had a very rough idle. When I reset the ECU the idle and drivability got better. So either the tune is funny(which I doubt because even at Rev 1, infamous is pretty good) or a sensor is giving funny readings and messing with my fuel trims, etc. I do, for sure, have some bad endlinks. I have heard people say that they got flash knock readings from the click/thump they make. Those will get fixed ASAP. So maybe the computer is pulling too much timing in some places in closed loop and causing a misfire. But I don't know how much timing is able to be removed by tuner ecu. So maybe this isn't a problem.
  4. I'll start TYPE OF STUTTER/STUMBLE Steady throttle/Increasing throttle/Both: Increasing throttle (often), steady throttle (very rarely) MODS Intake: Perrin Turbo Inlet, FMS TMIC Exhaust: OBX catback, CNT Catted DP Fuel: Stock Turbo: BNR 16g Engine Management: Accessport Tuner and revision of tune(if you don't mind): Infamous1, Rev 1 (on a retune, changed mods) MAINTENANCE Sensors changed: Cleaned MAF, no change. Plugs changed: none Coil Packs changed: none OTHER SYMPTOMS Check Engine Light: Just got a PO302 the other day and reset ECU and it's gone and didn't come back Etc. Had boost leak a while ago and fixed it. It did help a little. RESULTS What has and hasn't worked for you: New tune and/or resetting ECU mostly "fixes" the stutter. If something worked, how long has it been working for: Only lasts for a few weeks and I have to reset again.
  5. Lets see if we can get a handle on this issue and get a repository going of what mods people have, what they have tried to do to fix the stutter, what tests they have run with either good results or no results. Let's define stumble/stutter as any form of hesitation at part throttle at either steady throttle input or increasing throttle input.

  6. What high gain setting? Is there a pot that will allow gain adjustment? My Belkin Aircast is distorting terribly with Siri and phone calls.
