you gotta remember, JWT is a small business. i usually call. while i do agree that there is a demand for the 98-99 se/se-l/se-r ecu, the fact is that JWT will never make it. they've had 4 years to do it and still nothing. the best you can do is get a 95-97 se-r ecu (or a 94-96 g20 ecu) and sent it to them for a core. if you simply wish to remove the speed governor and raise the redline buy the said g20 ecu and simply swap. if you wish to go w/ the JWT method, you're looking @ approx. $600 for the ecu. that doesn't include the cost of you buying a used ecu for a core. the first program is set for whatever mods you have done to your car. each additional re-programming costs $100. the S3 program is the same ecu, you would purchase it IF you had S3 cams. they can program for S4's C2's C3's, etc. AFAIK nismo is concerned, AFAIK they charge around $1000 for their ecu's. i'm not even sure they would have a program for our cars. if they didn't, chances are they'd just call JWT and buy the program details!
