I used the search function on the wiki to try and find info on RKTI, clearly theres more behind the accronym.
I really really need information that is researchable rather than accronyms i don't know what they stand for. If i need to find something in the FR, then it needs to be in german... If its on the wiki, english....
I said i was a noob, but i cant do anything with what you're providing me...
Give me something i can use, help me learn...
Google "RKTI Nefmoto" = http://www.nefariousmotorsports.com/wiki/index.php/RKTI_11.40_(Calculation_of_Injection_Time_ti_from_Relative_Fuel_Mass_rk) |

did that
found this:
RKTI 11.40
Calculation of Injection Time ti from Relative Fuel Mass rk
Calibrating for injector battery voltage correction, different fuel pump pressure and different injector flow rates via KRKTE, correction of errors due to pulsation in returnless fuel systems
Not sure if RKTI applies since my fuel system is RETURN. Just this part maybe? "Calculation of Injection Time ti from Relative Fuel Mass rk. Calibrating for injector battery voltage correction, different fuel pump pressure and different injector flow rates via KRKTE,?"
Not sure what to log.

I've told him to log and yes it applies on return less.
To be 100% sure ud have to disassemble it.
Personally don't touch them maps man. If set to x it won't lower load and you'll melt something.

Lower boost until you find out keep idc lower than 85% |

Agreed but I'm puzzled why even 11psi ends up maxing injectors... then again, I have never tuned a 1.8t with stock injectors... is that normal? Can they not keep up with 11.5 afr at 11psi? |

I did some very quick math and it appears they're undersized for him but further looking at commercial tunes don't mention injectors so puzzling indeed. Flow test then maybe? |

That would be absolutely ridiculous. 11 psi is stock on all audi and vw 1.8t 180 hp engines including tt and 20th AE, they all have the same injectors, two of my buddies have both, one a tt 180 and another 20th AE.
VW would not manufacture a car to intentionally max out original equipment.
Reading the stage 1 1.8t tune thread with his AK audi 1.8t, he has the same stock psi rating of 11.5 which means probably means the same turbo and the same injectors. He did not max out his injectors until after raising his psi to 17-18. Albeit, he has a returnless fueling system but that should not matter.
I dont remember comparing his IDC's before tuning and after tuning but comments in the thread support my statement, something is wrong with my engine, fueling or whatever, something is wrong.
I may have the injectors in my car flow tested after I get the ones back being flow tested now, just to have a backup set. That may reveal what the issue is.
Also, is lowering boost really necessary? I max out injectors at WOT 6000 rpm aprox. Everywhere else is getting 8.4 lambda AFR of fuel. Still not rich enough??!??

As long as you can keep 11.5AFR w/o maxing injectors you are fine. If you don't want BTS requesting 8.4AFR you'll have to tune the BTS maps accordingly. |

100 dc isn't good and the car reduces load.
I just suggest get fuelling safe and find the issue.
It's lowering load to meet ATR requested fuelling I think.
I'd be pulling plugs and getting the injectors checked sounds like you've covered most things already.
It's your car and my advice upto you buddy.

ATR will take over bts and lower lambda until the rich limit or it becomes happy again. |

no I mean LAMFA is set to level out to 8.4 lambda which is about 12.4 AFR give or take, I think. ORI values were .94 lambda (13.5 AFR) is 12.4 still too rich? BTS kicks it way down past that which I don't want but thats something to solve after I solve the fueling issue, not now.
Going WOT with a 12.4 AFR and BTS kicking it down to.....say 11.5 maybe less....I don't remember, is dangerous?
Also I asked LeRoy if I have the same injectors as him.

Once again, why are we messing with the tune? This seems like the biggest waste of time band-aid approach, that pretty much everyone looks down on here (rightfully so). 7 pages for a stock car with a stock tune that's having issues.  Also, can someone mention what map/scalar is the trigger for ATR on a car without an actual EGT sensor? |

All I was concerned about was maxed injectors buddy.
If they're maxed and shouldn't be hw issue. It been repeated a few times.
