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. http://****************.com/smile/emthup.gif

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

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?

Ch02 : Fuel Tweak (Accel Pump); Increasing Loads
-This channel adjusts a fuel enrichment term when on the gas/boost or accelerating.
-Modulates Throttle Response
Ch03 : Fuel Tweak (Accel Pump); Decreasing Loads
-This channel adjusts a fuel enrichment term coming off the gas or decelerating.

Re: Lemmiwinks: The guide (Don R)

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?

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

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.
