Hi, Please try my modded TMM9 adx that have been changed to lambda (with my Spartan controller) instead of AFR and Boost in Bar instead of PSI. Battery voltage and injector duty works as well. Might need some tweaks to fit your setup..

Hi, I believe that the Turbo Tuner Usb ECU:s have an ostrich inside. Both for Motronic 4.3 and 4.4. I have my own ostrich and also a 4.3 TT Usb ECU as a nice backup (never teared it apart yet). // Turboforslund

Hi, How did you manipulate the system voltage? Are you sure it is above 15V when flashing? // Turboforslund

Hi, I mapped my engine with a stand alone WB lambda unit from ETAS (LA2). It was a good thing to have a second trustable source of the real lambda. Do you know any mechanic or company that has a lambda probe or likewise to insert in the exhaust while at idle? In Sweden we need to pass a yearly inspection including lambda at idle and elevated idle. It is always hard to know for sure when you only have the ECU values. // Turboforslund

Hi, Good post with a lot of info and digging. Have you compared the NB voltage vs. WB lambda to see the true Lean/Rich - swithing point? Might not be possible to compare them both within the WB Mod? (I got it but haven't tried it yet). // Turboforslund

It would have been awesome if Tunerpro would been able to create and handle .dcm files. I work as an engine calibrator as proffesion and our calibration tools such as ETAS Inca or ATI Vision would compare those bins and create a .dcm file to display all the cal-changes in between them. The .dcm could then be "sucked in" to any desired bin to make the desired cal changes. 🙂 // Turboforslund

Hi, That bin seems to need a different xdf to fully match. That seems to much off to be trusted. Wanna send it to me for investigation to get a better xdf for it? // Turboforslund

Hi, Had a look at an old post of mine from 2015: Hi All, I did check the matching of my previous "609" LPT xdf towards the original bins from Motronic suite. It did match all bins except 606, 607, 608, and 612. (note: STD rev5b works with these except the code specific features) Compability list (please correct me if i'm wrong): 0261204442, 0261204443, 0261204444, 0261204446, 0261204446, 0261204448, 0261204449, 0261204450, 0261204451, 0261204456, 0261204457, 0261204459, 0261204609, 0261204765 + more unknown. General XDF for these bins: https://www.dropbox.com/s/mx1hfr3xlcfp3dn/Turboforslund_General_XDF_v1.xdf?dl=0 0261204305 seems to need a 3rd type of xdf... // Turboforslund

Hi, Haven't tried it but it should be possible. I would suggest to log the NB emulation signal (raw voltage) while having the standard NB still in place. If they behave similar in voltage at stationary conditions I would see no issues with that setup. Do you see any benefits by running WB sensor with NB emulation instead of WB measurement and/or WB controlled? I guess a real (stock) NB sensor is always the most trusted "truth" in the end. Rich or Lean. Nothing else. // Turboforslund

Strange. Spark timing should be 20 to 10 deg before TDC to avoid issues. Earlier than that might be bad at tip-in. How about crankase pressure? Oil consumption? Bad oil scraper rings? Compression test? Heat value of the new sparkplugs? Any adjustments done to the idle position of the throttle valve? Low inlet pressures (below 300 mbarA) at motoring/idle will pull up excessive amounts of oil = knock. // Turboforslund

Hi, Dwelltime should (in modern ecu's) differ/ be compensated depending on system voltage to maintain the same mJ of spark energy at the plugs. Some platinum sparkplugs can react to ethanol blends in the fuel. Pre-ignition might occur but on higher loads. Sweden tends to increase the percentage of ethanol in our "gasoline" every now and then but i'm not sure if UK has the same blends. Is it reproducible if you disconnect the altenator? Is the enrichment a part of the built in safety function when knocking occurs? // Turboforslund

Hi, Some questions to understand it a bit more. Octane level of your fuel? Inlet temperature, oil age? Ambient temp? Is it still the same ignition timing and lambda value? Sparkplug gap unchanged? // Turboforslund

Hi, My loadvalue @ 4500rpm and 1.2 bar of boost is ballpark 8.1 ms (when looking into some old logs from 2015). 630cc injectors is at 65% duty and airmass at that loadpoint is 695kg/h. Wb lambda at 0.85. My pressurized MAF of 3" might bring those values down a bit. My understanding it that you cannot just add more than the max voltage out of the flow meter. If you get yourself a bigger MAF you drop in resolution but gain in margin. // Turboforslund

Hi, Good question. I will try to find some measurements from the tuned setup. Right now the power is reduced (to approx 300hp) to be able to pass inspection/registration with the supercharger+turbo setup. // Turboforslund

Hi, 24.48 is only better resolution afaik. I run GTX3076 (with pressurized 3" MAF) and 12.24 ms Software without issues. Approx. 450hp. // Turboforslund
