I'm looking at upgrading the ECU in my car as I have nfi whats in it, and yer basically would love to upgrade it and have the car running at its best potential.

I have a 1994 Honda Integra VtiR, T04E turbo etc

I've done some reading and it seems something like a Hondata ECU is most applicable for upgrades in Honda.

But I would like to know which is most suitable for a turbo application, would something like a Hondata s200 or something be able to be used. I know there useable for boosted cars and allow for Expanded fuel & ignition tables for boost.
From this link. http://www.hondata.com/s200.html

But I main question is what ECU should I be looking at?

Where would I be able to purchase one?

And where in Sydney are the "preferred" for Honda Tuning? (TODA, DR.Honda etc)

I know this sounds a bit stupid but any help would be appreciated
