Yo, looking for some advice

Have an Is200 with a TTE Supercharger, has FMIC and HKS FCD thats basically it, car is being fitted with decat and manifold this weekend and full exhaust.

Is it worth while getting it mapped? If so would i need a new ECU? And what kind of ECU could be used?

It's my understand, that the stock ECU is basically self mapping. With the new bits fitted, drive it about a bit, then park it up, disconnect the ECU from the power (fuse out will do) leave it for a while (some say 3hrs, some say as much as overnight) then reconnect, drive it about a bit and it "learns" what's going on, and sets out new parameters to run properly.

You should also have a post over on OJC forum, and ask about getting one of Patrik's "black boxes". Apparently it makes the WORLD of difference compared to the HKS FCD, and is much much better
