I was thinking of swapping my ECU from my ST185 for an ECU of ST205, but before I do that I just have a couple of questions;

1. Would it be just a plug and play?
2. Does it have a any significant changes power wise?
3. Should I just find an aftermarket ECU to work with?

I'd like to get some of you're guys' feed back on this because I don't know too much about this.
Thanks :D :D

It's not as easy as that, unfortunately, or we would all be on gen3 ecu :D
You'll need:
  • Re-pin or use a 2nd gen to 3rd gen jump harness
  • 3rd gen ECU
  • 3rd gen MAP sensor
  • 3rd gen 540cc injectors
  • 3rd gen MAT sensor
  • 3rd gen ignitor
  • 3rd gen cams (recommended), or ACG for your existing cams
  • CT20b or something that will flow a bit more than the ct26 to take advantage of the upgrade to gen3 efi

I'm currently doing the same to my mr2 and those are what I used. It does enable you to bridge the cap between 2nd gen efi and standalone, while managing smaller turbo upgrades (ct27, 20g, etc..) pretty well. Most say drive-ability and overall response is improved as well. HTH

Beat me to it. Personally I would go with a standalone ecu. I will be fitting an ecumaster EMU unit in mine, then I can think about changing bits and pieces ( I have some sard 800's waiting to go in) this unit, once you have the 3s gte to EMU adapter unit should plug and play
