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

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.
