How "plug and play" is the Haltech Pro for R33 GTST

[jacobzking]

I'm looking at the Haltech Platinum Pro ECU for my 93 R33 GTST.  With the base map loaded, should it be a plug n play with similar tune to OEM?  Or do they really need to be tuned, even on an otherwise stock car (intake, turbo-back exhaust)?  I do have an AEM wideband to monitor AFRs.

Also, I'm assuming I can use my Bosch sensor that's already installed on my downpipes (just before the high flow cat)?

Any tips for setting the thing up?  Other "upgrades" to consider to the ECU (z32 or r35 MAF)?  

Any info would be appreciated.  Thanks!!!

It is plug and play, load up the base map and off you go.

Throw the stock MAF(s) into the bin and run an intake manifold vacuum/boost reference to the ECU.

Preferably to run it to an external MAP sensor.

Get a Haltech CANbus wideband.

If you haven't bought the ECU yet, I would strongly consider buying a modern ECU. Yes it is very easy to setup and tune, however it is lacking many of the features of a modern ECU.

The pro plug in is something like 10 or 12 years old now? Can't remember exactly but it is very dated now. In that time the Elite was released and now we have the Nexus platform. 

I would strongly consider not buying the ECU that is 3 generations old now (especially as it isn't a cheap ECU!).
