You do know you can send it out to be repaired right?

ECMTuning, Inc.

Ya u can send it out to get it fixed. ECMTuning is the best company around for this or you can order a new ECU from them, or you can search craigslist or classifieds on here... since there is a 99.9% chance you don't have an EPROM with that serial number any ECU from a 95-99 will work fine.

That's not an RS ECU it's a GST ECU from a 97.
Where is it burnt?

I thought I have pictures from the 97 ECU's I've fixed but I can't find them to tell you what that trace was for. Most of the problems like that tend to be from user error either by modifing the engine harness or from miswiring O2 sensors but somethings, very rarely, it's natural causes.
 
Ah, so you're the Steve that does the ECU work. I keep forgeting about that otherwise I would have posted you up as well. You should post an ad up on the classifieds for ECU work.

you cant possibly have a rs ecu the rs and gs ecu's are on the outside of the car under the hood and your car would not even run being calibrated for a map sensor seeing no boost! the rs/gs ecu is also a huge box with like a heat sink on it way different.
