Here's the situation, with the ARC1 I was able to adjust the a/f ratios pretty damn close to perfect but only when the car is warmed up. When cold it's still running too lean, causing lumpy throttle response and flactuating idle. Seems there is nothing I can do about it using my current tools, but I noticed that Lemmiwinks has 2 adjustments called "Startup fuel enrich" and "Warmup fuel enrich". I can't get Lemmiwinks to actually work on my car, but I believe the settings it provides should be accessible via VAG if you know the right block to adjust, similar to idle speed adjustment, right? So the question is, what block do I adjust to get to these settings?
