ECU upgrade pro's and con's?

The con's are simply engine wear and risk.

The pistons in the N-GT 360 are much lighter than a road car...and they are limited to only 9000rpm now, and used to be 8700rpm.

I've seen 3 N-GT engines fail where the small end of the conrod has failed and sent the piston into the head.

The extra heat, noise and vibrations at those extra rpm cause all sorts of knock on effects in terms of stress and fatigue of all components and ancillaries.

You'll always gain far more from weight saving, tyre choice, suspension set up and driver training........

If I did a PPI on a road car with upgraded ECU's, I'd recommend against buying it, or adjusting the price significantly.

 

I was also interested in an ECU tuning and learned the following:

There are companies which offer a standardized chip with a modified characteristic. Prices here in Germany vary heavily from approx. 200 $ to 2.000 $.

And there are companies which claim that escpecially with an older car the chip program has to be individually adapted to the specific car. They only make upgrades if you bring them the car for a day or so. Prices are in the range from 1.500 $ to 2.000 $.

I am unsure wrt the best solution. So I rather decided to wait a little until I have more knowledge.

 

If you are a driver who regularly laps every other driver with similar and more powerfull cars, then you can use the upgraded ECU. Otherwise, invest this same money in track time and instruction until you achieve the status of the first sentance.

Or to put it another way:

When you can lap within 2 second of the lap record of you car (same tire catgory), then you can start messing with the suspension and engine stuff. Until then, leave the car stock and practice practice practice. Rest and repeat.
