    Do you have a log? Seems like a lot of timing to me.

    hello,

    1. according to the log your narrow bands are not close at WOT you have a discrepancy there. Bank1 is lean and Bank 2 is rich

    2. that is the weirdest timing table i have seen

    3. why you have no timing adjustment (for higher IAT or Coolant)

    4. disable spark smooth

    5. your Airmass load is around 1.8 and your last row in the timing table is 1.2 your (which your should base your engine timing on that last row)

    1. The way my turbo kit was built both 02's feed from one bank so I have them disabled.
    2.It is a table I received from a friend and I am still working on it I will post my new tune.
    3.It never gets above 105 iat or over 200 so I have not addressed them yet.
    4.I am actually fighting with my timing at idle the over under has it all over the place I am working on that now also.
    5 Are you referring to the g/cyl?

    The knock issue is fixed the exhaust wrap for my down pipe came loose and my plug wire was arcing and finally failed last night, new plug wires and heat wrap and its running very well now except the idle and idle coming to a stop. I do appreciate your advice and looking at my issue.

    ok I really dont want to start another thread so if someone sees this and has a suggestion cool if not I will just keep trying things I have read about. I cant get the timing at idle to stop swinging so much and not die on me, also after lowering the idle rpm and tuning some of the ve and spark it wants to die sometimes. I have done the raf table several times and if i turn the ac on it does not dip when coming to a stop. The tune is the post above this one and here is a log and the config I used to see what the timing was doing.

    If you want it to stop swinging at idle, 0 out your overspeed/underspeed tables, but I'll tell you that it does that on purpose and it's the quickest way to keep the idle speed in check. I highly recommend you start with a stock tune and work from there. What you're working from now is beyond help and just going to cause you to chase your tail until the end of time.

    Hey thanks for the advice this is actually the same tune from whenI purchased the car when it was supercharged. I just updated to a 3 bar and changed some things to match the turbo. I will use a stock tune and copy all the tables over minus the ve and tq management stuff and go from there. I didnt realize this thing was that jacked it ran well with the charger on it. Again thanks
