Title: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: munro on December 01, 2015, 12:35:13 PM Just wanted to say this is a great thread -- After reading through it about three times, the light bulb came on and I think I finally understand well enough to effectively update the following tables in "concert"... KFLDRX(NW), KFMIRL, KFMIOP, and KFPED while avoiding (minimizing) torque intervention. ok guys my question will seem stupid but you can adopt this intervention logic for good remapping?I ran into all the problems mentioned in this thread... Raised KFMIZUFIL thinking that would keep torque intervention from being an issue, but I only caused lots of level 2 interventions -- very inconvenient "throttle shutdown". I experienced the strange timing oscillations too -- it was audible in my exhaust note while cruising. One piece of advice that stuck with me -- Rick said that tuned KFMIRL/KFMIOP, but then fine tuned with KFPED. That really helped lay out the process for me... Start with KFLDRX, then design the KFMIOP axis you need to achieve those values. Create KFMIRL values by translating KFMIOP stock table values "through" the new KFMIOP axis. Finally, cross-check requested load vs max requested load by processing KFPED thru the new KFMIRL and KFMIZUFIL thru the new KFMIOP. Reduce KFPED whereever requested load is above max requested load. I've skipped a lot of translating and interpolation steps, but you get the idea. Once I had this modeled in Excel (nothing fancy -- manual interpolation using freeware Xlxtrafun, http://www.xlxtrfun.com/XlXtrFun/ReadMeXlXtrFunAndSurfGen.htm), I found I could optimize my pedal response while also avoiding torque intervention. The stock KFPED wasn't very aggressive at low pedal angles and low rpm, which makes driving a turbo standard transmission harder than it needs to be. I also found my stock KFPED was designed to violate KFMIZUFIL (induce torque intervention), which I wanted to design around. Why rely on a safety mechanism in normal operating conditions? Thanks to everyone that took the time to document their issues and discuss solutions. I don't know how I would have figured this out otherwise. I'll explain in the ECU edc16 that is based more or less like the motronics with torque control when I go to remap the various maps act starting to change the driver wish having in mind the level of the couple who want to get a result and then a given amount of diesel injection taken this step to eliminate various limiters that can hinder this process and as a result of this i add my level thrust bearing in mind the conditions of the turbine engine clutch etc ... what I want to understand there is a rationale for intervention in motronics on we can base?

So reading around a bit better on the forum seems to have realized that the first thing for an edited file you act on the supply by monitoring the mods do with a stoichiometric player .. in this process if it is replaced maf trying to adegaure carburetion monitoring the STFT and LTFT ... then go from there to various controls and maps for increased turbo boost which I think is also involved kfmirl .. and then go to advances .... am I right? I missed some steps?

unfortunately my English is very bad, and I use the Google translator to write here but unfortunately this is not the best to ask technical things ... you have to have a little patience with me . :'( Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: Rick on December 04, 2015, 05:25:59 AM Forget trying to compare ME7 with EDC and petrol with diesel, they work completely differently.
Rick Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: munro on December 04, 2015, 11:19:22 AM Thank you for your reply
I know that compared to diesel fuel is not possible but I was wondering a method of remapping the me7 from what I understand by reading the wiki page s4 I understand that you act like this: 1) add fuel monitoring the afr 2) if it is replaced with a bigger maf you must be linearized or scale properly this in his map 3) increasing the turbo boost 4) review the maps ignition so it is?

Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: munro on December 09, 2015, 10:18:16 AM why?
Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: adam- on December 09, 2015, 10:21:22 AM It's basically that, yes.
Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: munro on December 09, 2015, 12:29:41 PM It's basically that, yes. can you please tell a less basic to modify a me7?please do not tell me to read the forum or wiki page already made it over and over again the problem is that I'm really a rookie with motornic and all the abbreviations alphabetic naming maps also need to translate from English into Italian and many steps incomprehensible to me ... Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: adam- on December 09, 2015, 01:07:10 PM Ask for lots of load.
Have sane timing values. Have a good fuel table (lamfa, KFLBTS etc). Ask for boost with ldrxn. Log, done.

I though I still have some doubts about the method of changing motronic in the sense that here in Italy with the most people I spoke to told me that increasing KFMIRL you add fuel .. I read on the forum that increasing the target filling (KFMIRL) you must lower KFMIOP to avoid the intervention of the torque control and the closing of the accelerator but all Italian tuner with whom I spoke say they also increase KFMIOP because according to them makes this map increase the peak boost ... I'm not understanding anything more .. what do you think? Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: adam- on December 10, 2015, 04:57:07 AM Leave IRL and IOP the same, Bosch got it right from factory. No % mods here.
Increase the LAST line on BOTH maps to 95% and 230%. Adjust RXN to a common sense value (150 at low load, peaking at 220 at mid RPM, tapering/not tapering depending on turbo at the redline), With good amount of load and boost, add fuel. Copy normal fueling maps. Log. I'm making this as simple as it can be.

Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: munro on December 12, 2015, 06:26:44 AM maybe this has nothing to do with the tread but would like to ask more expert information about KFMSNWDK ..
1) comparing different file known that this map has differences .. the release of this map seems to be in kg / h but I did not understand what it does 2) in the truth of a car of a friend I tried to raise this map following the logic of a map with the most power and the result is that the car is accelerated and the minimum pedal pressure gas rises even more speed .. can someone explain to me why? Title: Re: EDC and KFMIRL, KFMIOP, KFMIZUOF - Torque Monitoring sanity check Post by: adam- on December 12, 2015, 06:52:17 AM Why did you change it if you don't know what it does? You cannot just change maps with the reasoning "Well this other file has it, so it must be right". Understand what you're changing, then change it, then log to make sure it's doing what you expected.
The map is measurement of airflow over the throttle plate. A 15 second Google would tell you this.

You cannot just change maps with the reasoning "Well this other file has it, so it must be right". Understand what you're changing, then change it, then log to make sure it's doing what you expected. ok just what you say but if you mount a FMIC and from most press turbo do not need to edit this map?The map is measurement of airflow over the throttle plate. A 15 second Google would tell you this. files me7 180-225 hp these maps are different because I believe that the turbos are different K03> K04 and "slide" more air .. how should I set the google search to understand this?
