Since a few of you here REALLY want an upgraded ECU here's an idea you may want to consider if you can't wait or plan to have your car for a while. JWT has cracked the 1997 ECU, and it will work in the b15. The only catch is you will have to splice it in. In other words, you will have to chop up your factory harness. You may want to keep this in mind because here it is 2001, and JWT hasn't gotten around to hacking the 1998 ECU. Besides, using the 97 ECU may allow you to go straight to the turbo kit JWT is offering
(as seen in turbo magazine).
