Or is it possible to get a scaleable stand-alone?
Most standalones are fully programmable sytems. Some standalones are scaleable with respect to secondary features like launch, boost and nos control, etc.

Considering all the mods, an ECU with scaleable features is not a must..

It is the the mapping that has to be changed to optimize the system for whatever mods are coming in.

An example-
Changing fuel and ignition maps for a stock car wil give it performance gains no doubt.

Next I install a free flowing airfilter and an exhaust system , so i re-calibrated fuel and ignition to compensate for a little more airflow due to filter and change in cylinder filling due to exhaust headers.So i optmize for these addons

Next i install a wilder camshaft, so i re-calibrate maps for different operating characteristics ( engine volumetric efficiency ).

Now i go for a turbo. i would have to upgrade to a vacuum/boost sensor (if the existing ECU did not have it) and then back to calibrating maps.

So whatever the mods on the engine or its systems, an engine management system should be set to take these parameters into account to extract the best from them.

Hey RD Agree the ECU can help from day 1 itself the only reason it is typically set on stage three is for the following reasons:

1) You need a skilled person with experience to do the initial install and tuning
2) Better gains noticed with additional mods
3) Costs

The only reasons stand alones get pushed to later is because they are not plug and play like other simpler devices.

I have a 2003 Honda City VTEC. I would love to modify my car and was searching for the information posted here. It has helped me greatly. Thank you very much GTO. One last suggestion from anyone - Where do I go to modify my car in Bangalore - Who is a specialist with Honda City Vtec considering its different technology. Thank you.

Binoy, there is another tuner who specializes in Honda's these days. He is the one stop shop for any Honda engine transplant/performance parts etc and supplies parts to other tuners too. I am sure you know who it is .
