Hi,
The impression i get from the yank forums...it is a risk getting at as they are not genuine

I agree with 88-GTR.  Generally, modified chips don\'t get a great press in the USA and are pretty inflexible.  Probably Knight Sport is a safer bet because they have a brand name that they don\'t want to damage.  

Overall, though, you\'d be better of going to an aftermarket ECU like the Microtech or similar.  This will let you plan for more mods later.  The only pain is that the current Microtechs can\'t run the 89-91 electronic metrering oil pump (they keep claiming that they will do \'one day\') so you will need to use premix or convert to the 86-89 mechanical MOP.  

Or you go for the Motech (which is expensive) or the Apexi Power FC (which probably isn\'t too cheap either as you need a special loom converter to fit the FC3S).

Good luck with your FC3S whichever way you do decide to go.

Best wishes

Peter
