I'm new to tuning i have a 98 Passat 1.8t i downloaded winols and have a usb to obd2 wire coming but have no idea where to find tune to flash onto my ecu

To get started, there are no easy, free tunes available on this site. MPPS is the only GUI-based tool to flash your ECU, and while some members created a CMD-based program for M3.83 and M5.92 ECUs, I didn’t have much luck with it. For a 98 1.8T, you’ll need to match the software version of your ECU with the right file to flash. VCDS is the best way to find your ECU's software version.

You can find original files online, but make sure to use the correct one for your version. If you're in the USA, note that early drive-by-cable 1.8Ts don't have an immobilizer, unlike European versions—cross-flashing the wrong version can prevent your car from starting do to the immo system. You can also find Damos files for M3/M5 ECUs that will help you create a map pack, or you might get lucky and find one that already fits.

If you’re looking for a more straightforward solution, I can provide stage 1 or stage 2 tunes that can be directly flashed onto your ECU. Keep in mind, for safety, it’s best to use a wideband AFR gauge to monitor your fueling, as there’s no stock way to do this. Also, since there’s no boost pressure sensor in your car, you won’t be able to monitor boost with VCDS.
