The main benefit of an after-market ecu on a high-(ish)-ly tuned NA engine is that they ARENT speed density based, and so arent as delicate when we are looking at fluctuating inlet pressures. Yes, as Paul says they are typically alot simpler in terms of functionality, and this is a good thing for the above reason. They are also alot easier to map because of their simplicity, and better software manipulation.
Simpler doesnt necessarliy mean it does the job worse....in most cases they do it better, as its scrubbing engine control back to basics i..e giving the engine what it wants/needs when it wants it, with minimum hassle.
In the case of this turbo 182 where there arent the problems outlined above, I would suggest letting someone like Paul with experience of manipulating the stock managment have a bash at mapping it. In short the stock managment is capable of meeting your needs without any hassle, so long as its calibrated correctly.
