  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.
  15. Bringing this back to ask if I could in theory tie my 4 aux injectors in series to my main injectors on the trigger side and then us a relay to only apply the 12v B+ to the secondary injectors under a certain level of map pressure so as to keep the aux injectors in sequenced mode but only use them when needed for the high map level of fuel? I do understand that I would have to lower the numbers in that part of the fuel map at the moment where the aux injectors are brought in of course.

    Lock ecu

    That will work!

    Lock ecu

    Is there a way to lock the G4+ ecu so as to render the car/ecu temporarily unusable for security reasons and then be able to log back in and make it driveable again quickly? I might have overlooked this already and it might be obvious but I dont off hand remember seeing it.
  18. Another possibility is your timing light is goofing up.
  19. Is there a way to make the text in these forums appear darker? its tough to see with the light background?
  20. Could you have had hydraulic cam followers that took some time to bleed down? possibly holding an intake valve slightly open...
  21. Are you certain that your injector dead times are correct?
  22. In my experience with E85, they are typically harder to start when its cold or the car has sat for a week or so, I havent came upon a good fix yet, although I have tried a few different attempts, that being said the stock ecu had the same issues with E85 so its not just standalone having the problem, its possibly the injectors not atomizing the ethanol as well as the gasoline and the higher flash point and water intrusion that happens with ethanol.
  23. You can retard your ignition as much as 20 degrees but I wouldnt go much farther than that and then add fuel enough to make flames if you really need to, but keep in mind that it can be hard on parts, including your turbo, exhaust manifold, and if your not careful it can cause valve to piston contact in some cases.
  24. Most people would just rather have their car run clean and pull nice, this crap is why the import culture gets laughed at and not taken seriously, making noise and fire just to annoy people that dont want to hear your car or see your car making exhaust fire shouldnt be your main priority, try to go fast with some CLASS, that will get you the RIGHT kind of attention for a change.
