  1. In my experience a lot of the 4g63's do this, your likely in too high of a gear and are lugging the engine especially if you have aftermarket cams in it, I use overrun fuel cut as mentioned to make them stop doing that.
  2. You understand that the turbo flutter that you describe is compressor surge and that compressor surge is damaging to a turbo?

    Trigger Setup - Evo 5

    Are you running gasoline or E85?
  4. Ive had the same issue and figured it was something backfeeding for some reason, I now realize that I do run the newer software and have since it first came out so it could be an update issue, I just turned off the hold on the ecu to stop it because my check engine light would stay on permanently though very dimly and the ecu would not ever power down if I let the ecu fully cycle the fuel pump relay, if I turned the key off before it shut off the fuel pump by itself, the ecu would power down properly after a few seconds and after moving the idle control motor, if I let it stay on after fuel pump prime then the idle control motor would never move after key off and as I said the ecu would never actually power down, it keeps the control relay powered with less than 12v, I think I measured around 5v on the relay keep alive coil.
  5. The tables look a little generic to me with a good bit of interpolation.
  6. The car needs tuned, the tune that comes from Link is just to get the car up and running so you can get it to a tuner or tune it yourself, I wouldn't be making boosted pulls with it until its properly tuned.
  7. Thank you very much for the quick and easy to understand reply!
  8. Could you share this information with me as well?
  9. Gotcha, thanks for the quick reply, thats all I was wondering!
  10. I have a simple question, when using the dual fuel table, is the percentage the percentage of fuel table one that will be used or the percentage of fuel table two that will be used at say a certain ethanol level. For example if I set the axis to ethanol percentage and I want to run fuel map one at 50% and up ethanol and I want to run fuel map two at 80% when ethanol content is 40% or less how would that look as far as the numbers.
  11. Research the Bosch wideband type of knock sensor and its advantages.
  12. What Im getting at is that AEM sensors dont seem to have super high quality anymore, youve had one fail, it might not be the last.
  13. Im not sure if I could trust that setup, why not just use a 1:1 rising rate fuel pressure regulator and simplify things? even if you wanted to simply log fuel pressure you could without using the output to alter the ecu's calculations.
  14. I would suggest in the return line right after the fuel rail/regulator, that should give you the best indication of the true fuel temp reading. Some ethanol content sensors have the temp reading built in btw.
