    Thread: Lemmiwinks: The guide

    1. 10-03-2004 05:03 AM #1
      I'd like to built a good guide to understand 100% how to fine tune our engines with the help of Lemmiwinks, as nobody has done it before and all the info is spreaded all over the forums.

      Please help me complete this guide posting all the information you have about all adaptation channels, if some of the specs or definitions are wrong please post and I'll update the specs on the original post, I'll do it until it has been done right.

      Ch01 : Idle Speed Offset
      Adjust idle RPM level
      - Higher number: increase idle rpm
      - Lower number: decrease idle rpm

      Ch02 : Fuel Tweak (Accel Pump); Increasing Loads
      -This channel adjusts a fuel enrichment under load
      -Modulates Throttle Response

      Ch03 : Fuel Tweak (Accel Pump); Decreasing Loads
      -This channel adjusts a fuel enrichment term coming off the gas or decelerating.

      Ch04 : Start Up Fuel Enrich
      Amount of fuel on any start ups?
      - Higher number: enrich the mix
      - Lower number: lean out the mix

      Ch05 : Warm Up fuel Enrich
      Amount of fuel on start ups E.G. on the first start in the morning?
      - Higher number: enrich the mix
      - Lower number: lean out the mix

      Ch06 : Lambda Regulation
      Controls how fast ECU adapts:
      - Higher number: faster adaptation
      - Lower number: slower adaptation

      Ch07 : Additive Offset To Speed Limiter
      Controls speed limiter in increments ok 1km/hr

      Ch08 : Secondary Fuel Tweak
      It adjust gain on the injectors responce
      - Higher number will increase the injector responce (smooths the ride)
      - Lower number will decrease injector responce (decrease backfires)

      Ch09 : Ignition Timing Offset
      Controls timing in steps of 0.75 degrees, all RPM range is altered
      - Higher number advances timing
      - Lower number retards timing

      Ch10 : Primary Fuel Tweak
      Controls fueling on run, ussually change multiplicative fuel trims
      - Higher number enrich the mix
      - Lower number lean out the mix

      Ch11 : Unused
      Unused

      Ch12 : SEL Scaling (Turbo Cars Only)
      Adjust fueling maps according to boost settings
      - Higher number increase injection period for higher boost
      - Lower number decrease injection period for lower boost

      Ch13 : OFF OFF
      Unused

      Ch14 : Idle Torque Additive Offset
      Controls engine load at idle
      - Higher numbers: spec load at idle is increased
      - Lower numbers: spec load at idle is decreased

      Aditional Information from Revotechnik:
      Adaptation Channer Explanation
      Revo Comparison of Adaptation Channels and Tuning

      Download Lemmiwinks Now from Ecodetuning
      Download Lemmiwinks Now from Unixprohost

      How to:
      1. Place key in ignition, turn to on position.
      2. Attach VagCom 'dongle'.
      3. Bring up Lemmiwinks software
      4. To store original ECU settings Click ON "Read". This reads your current settings.
      5.Adjust settings at will.
      6.Click on 'SET' to connect to the ECU and adapt settings.
      7. When asked to cycle ECU, simply turn it off, then turn the ECU back on.
      8. Enjoy (hopefully) new settings.

      Hints
      1. Take off your Instrument Cluster Fuse if you can't establish communication with the ECU. clear airbag DTCs.

      Special thanks to Don R, MRP2001GTi and BMFJETTA for great information.

      just updated the SEL scaling channel

    4. 10-03-2004 06:07 AM #4
      i know mrp2001gti knows how to play with channels 2 and 3. maybe he can chime in.

    5. 10-03-2004 08:20 AM #5
      Quick question, when hitting the "read" button, does that read ur settings as u have them now before u mess around with it so u now what ur original settings were?

      Also I have read that lemmiwinks begins to not adapt after a while, will I need to re input my settings after like a week or something?

      anyoe still have those drivers or emulators to make the usb port think its a com port?? there was an old thread about it but the links were corrupt..

      is there a way you can save your "stock" parameters BEFORE you start changing them with Lemmiwinks? Because if you reset Lemmiwinks, it just goes back to the default Lemmiwinks parameters right? THats what makes me shy away from Lemmiwinks , no way to reset it, or to know where you were when you started right? Maybe im wrong?

      Just hit default and make sure you are using Lemmiwinks with Windows 98 SE or higher.

      so that sets it to the ECU's default? Or Lemmiwinks Default?


    12. 10-03-2004 10:27 AM #12
      does it have to 98 SE? I have win 98 but i dunno if its SE?

      Sets it to the ECU's default and yes you should be running it with 98 SE.

      dont run this on windows 95 whatever you do.

      It will set your default values from 128hex to 100hex... And the car will not run.

      Default values are like this before you tweak anything:

      Addaptation channels changes software map defaults, but ECU will take some time to adapt new settings, that happens all the time you clear DTCs even if you never touch lemmiwinks

      Software can be used on any DBW engine even if it wasn't Revo upgraded, unfortunately I got DBC

      If someone knows a valid link to download lemmiwinks send it to me so I can post it on the top of the thread

      I got this from compusa some time ago and it still works like a charm, my laptop as all new ones doesn't come with serial interface

      http://www.ecodetuning.com/revo/Lemmiwinks.exe

      Primary and Secondary fuel tweaks should only be used to bring your fuel trims back to 0.0 They do richen and lean the mixture but your ECU will try to adapt so they are truly only useful for bring trims back to 0 or adjusting the mixture and staying within the limits of plus or minus 10% .

      Example, lets say you unplug your MAF and drive your car around for 50 minutes to let the ECU adapt out the richness. Lets say your trims end up at -9% and -18% (typical). You can use the primary fuel tweak to correct the off idle trim by lowering it 18% then resetting your ECU.

      On the above example you could lower your secondary 9% to bring the idle trim down to 0 as well.


    21. 10-03-2004 12:38 PM #21
      I have found tweak two and three helpful to adjust mixture under load. To get rid of the richness when you let off (popping and backfiring) I have set decreasing load to about 90%, my increasing load is 105% because I lowered my fuel pressure to 2.5 bar to get WOT AF closer to 12 to 1.

      An no you dont have to put your setting back in after a week. They do not "adapt out" so to speak. Yes the ECU tries to trim out to 0 after but trying to adjust your mixture using the promary tweak outside of what the ECU wants is not what I use it for. I adjust it to keep the trims within the spec range.

      This means that if you increase Channel 2, mix will be enriched in additive increments as rpms raises? does it increment according to load?

      LOL people still have windows 95? FYI it works great on Windows 2000 and Windows XP.

      I'm new to lemmiwinks, Could I turn down boosts via channel 12, would I be able to do this without adjusting fueling, for the snow. I understand that doing this will decrease the requested boost from the ecu, will the ecu adapt fueling or will I have to?

    26. 10-03-2004 01:43 PM #26
      just get a MBC

      good info
      so basically adjust the fuel pressure first for WOT AF
      then fine tune fuel trims (channel 2 & 3) w/ lemmiwinks

      This means that if you increase Channel 2, mix will be enriched in additive increments as rpms raises? does it increment according to load?

      It will be enriched proportional to the increase in load. Load will level off once you have fully spooled.

      Now when I go to put in my settings, the key should not be in the ignition? What does it mean to cycle the key or what every it says after it makes the settings?

    31. 10-04-2004 11:56 AM #31
      Step By Step how to change the ECU setting with Lemmiwinks.\

      1. Place key in ignition, turn to on position.
      2. Attach VagCom 'dongle'.
      3. Bring up Lemmiwinks software
      4. To store original ECU settings Click ON "Read". This reads your current settings.
      5.Adjust settings at will.
      6.Click on 'SET' to connect to the ECU and adapt settings.
      7. When asked to cycle ECU, simply turn it off, then turn the ECU back on.
      8. Enjoy (hopefully) new settings.


      Hope this helps

      Any Idea what vehicles are affected by this

      from the Revo Link

      "Other than having to pull the instrument cluster fuse (make sure VAG-COM
      will be able to clear you air bag DTC light before doing this!!!) on
      some cars we have not had any problems doing the limited number of
      adjustments available through adaptation channels."

      Will 2000 - 2004 1.8T's get an airbag DTC? Will we have to pull the clutster fuse to get this to work?

      Nope, no airbag dtc for me J.

      john, isn't your airbag light on all the time anyways?
