Title: KFLBTS Problem with fueling Post by: maZer.GTi on February 12, 2013, 07:18:07 AM I have problems to get right fueling with this map.
KFFDLBTS = 1 FBSTABGM = 1 TABGBTS = 399°C i attached screenshot of my KFLBTS map, i see with this setup requested lambda 0,78 on high load/rpm. But my actual Lambda is < 0,75 and i cant get it higher. I lowered FKKVS up to 0,89 but cant get it over lambda 0,74. Under 4000rpm my actual lambda is very close to requested lambda, but over 4200rpm it goes crazy :( Does someone have the same Problem or can help me to get it working? thanks for help Title: Re: KFLBTS Problem with fueling Post by: phila_dot on February 12, 2013, 07:30:47 AM If target lambda is good, then KFLBTS is not your problem.
So, lamsbg_w is good, but lamsoni_w is rich? Why are you trying to fix it with FKKVS? What is your setup? Injectors, MAF, turbo...stock or...? Does your hardware allow you to run a stock file? Title: Re: KFLBTS Problem with fueling Post by: maZer.GTi on February 12, 2013, 08:16:26 AM Hello Phila,
no my hardware is changed a lot :/ 550ml Injectors with 4 Bar FPR. K04 with RS6 Wheel. MAF Stock Yes lamsbg_w is like i request in KFLBTS but lamsoni_w is to rich. I think this ecu cant show richer mixtures then 0,75 ( it shows 0,75 ) greets Andy Title: Re: KFLBTS Problem with fueling Post by: prj on February 12, 2013, 08:52:12 AM Pressure test and make sure you don't have boost leaks...
If you moved location of MAF sensor that can also cause a problem. Otherwise your KRKTE is wrong or fuel pressure is too high on idle (bad FPR). Start measuring physical things on the car, not playing with ECU ;) Title: Re: KFLBTS Problem with fueling Post by: maZer.GTi on February 12, 2013, 09:47:08 AM Lambda regulation is always near -10%.
Its only on wot and over 4k rpm. krkte should be good trims are fine :( Title: Re: KFLBTS Problem with fueling Post by: nyet on February 12, 2013, 10:35:02 AM 2nd hardware problems. probably leak post maf, pre turbo.
Title: Re: KFLBTS Problem with fueling Post by: maZer.GTi on February 12, 2013, 12:56:37 PM My Turbo is very damaged, he needs 1,5L oil on 500km.
Maybe Problem is that my wideband is showing me wrong values because my turbo burns much oil? greets andy Title: Re: KFLBTS Problem with fueling Post by: nyet on February 12, 2013, 12:59:50 PM could be.

Title: Re: KFLBTS Problem with fueling Post by: ddillenger on February 12, 2013, 01:18:00 PM We need a header at the top of the tuning forum:
DON'T ATTEMPT TO TUNE A CAR UNTIL YOU GET ALL THE HARDWARE SORTED! And if you do, don't waste everyone's time with it. Title: Re: KFLBTS Problem with fueling Post by: nyet on February 12, 2013, 01:20:09 PM Big thx, i stop trying to get it leaner now :) Either way, pressure test AND fix your oil leak, then go back to tuning ... :) |
