I did a few things to my E46 yesterday:
1. Wash / Sealant before winter hits, using some sweet sweet AMMO skin that a buddy bought.
2. Installed my Oppo sticker
3. Updated the DME (engine management) & EGS (trans management) in the car. This is the big one. A really nice guy a named Scott (BaliDawg on the forums) Remoted into my computer, setup INPA / Winkfp / NCS / Daten files, and updated the software in the car. It had never been updated from the factory. The car is now LOADS smoother, feels peppier, and the trans shits great.
Anyone who has an E46, you should 100 percent update your software to the latest version. It’s not a terribly hard process, but Scott will do it for free if you contact him. He’s done hundreds.
11/10 would recommend!
