Overview:

Tuning of Warmup carries some challenges that are somewhat different from the tuning your fuel tables. Where as when tuning your fuel tables you can collect data, make changes and observer the impact of those changes then readjust if needed,  with warmu up enrichment you only get one try a day. Once it is warmed up, you probably don't get to start off with a completely cold engine again until tomorrow, even then how cold depends on your weather. This is what makes Warm up Enrichment (WUE) Tuning an ideal candidate for auto tune. Your laptop can capture all the data needed to dial in your WUE in as little as 1 to 2 passes.

You may first want to familiarize yourself with the available settings in case you do need them, the default setting should work fine in the majority of cases.
Then go to the Using WUE Analyze section for the simple steps to have WUE Analyze correct your WUE.

Using WUE Analyze Live:
Operation of WUE Analyze should begin with a cold engine. If it is not that cold this time of year, not to worry, you can use it on the warmup from what ever temperature it is and perhaps come back to it when the weather turns cooler.

To begin using WUE Analyze Live:
  1. Power on your ECU
  2. Connect TunerStudio, and go to the WUE Analyze Screen by clicking on the "Tune Analyze Live - Tune For You" tab. There will be a sub tab for WarmupEnrichment1, select that.
  3. On the Warm up Enrichment Analyze tab, go ahead and click "Start Auto Tune". There will be steady active filters until the engine is started, so it will not begin processing the data.
  4. Now proceed to start your engine.
  5. Important! - Once your engine is running, try to maintain a steady RPM through the warmup process. Normally idle is good, but if you have an engine that does not yet want to idle while cold, hold the engine at a steady RPM from 1500 to 2500 RPM.
  6. Wait and watch. See what changes are recommended until it gets up to running temperature.
  7. Once the engine is warmed up, Do not turn off the engine. Review the recommendation to insure it appears correct. Then Click "Stop Autotune", then Burn.
  8. After Burn is clicked, the new Recommended WUE is saved to your ECU and you can turn off the engine. Try out your new WUE settings on the next warmup
