You can get a copy of the Mugen ECU for under 500$ CAN. While Trey is completely right about its limitations, it still is an easy way to make your V-Tec power more available.
I use one on my stock ITR. With it in place I can shave 1 sec off a lap (65 sec course) ....not because the engine is making more hp, but because I access the V-tec quicker....I believe at 4800rpm. In addition, the fact that it has no realistic cutoff, I can extend a gear and avoid an upshift that I don't want to do when a corner is approaching.
At 1500$ I would look for something else and especially if you are looking for straight line performance, but for quick fix on track, with no tuning headaches, it's a sure bet.
