  1. Maybe it has to do with having your pull up or pull down settings in your inputs?

    Modelled fuel

    You would use 500cc if thats what they flow at the pressure that you are going to run.
  3. If you lived local I would give you a hand with it. I would imagine your soaking your plugs with fuel right?
  4. That would be hard for me to swallow, I like to be able to make adjustments here and there when I get the car out, but I do understand why someone would want to, I guess "protect" what they consider intellectual work, although it wouldn't be all that hard to datalog the car on a dyno and fill in the blanks as to what the timing map and fuel map actually are anyway.
  5. Have you tried swapping your plug wires 1and 4 with 2and 3 to see if it will fire?
  6. I think its your map, but we would need to see your map to decide that, I can tell you that E85 doesn't seem to like large jumps in ignition timing on my 4g63.
  7. Your ignition timing is all over the place, your jumping like 30 degrees in a 500 rpm range.
  8. 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.
  9. You understand that the turbo flutter that you describe is compressor surge and that compressor surge is damaging to a turbo?
  10. Are you running gasoline or E85?
  11. 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 pu
  12. The tables look a little generic to me with a good bit of interpolation.
  13. 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.
  14. Thank you very much for the quick and easy to understand reply!
  15. Could you share this information with me as well?
  16. Gotcha, thanks for the quick reply, thats all I was wondering!
  17. 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.
  18. Research the Bosch wideband type of knock sensor and its advantages.
  19. 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.
  20. 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.
  21. 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.
  22. 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!
