Any of these kind of systems that claim to fix throttle response do not work for this particular problem with our 370Z.
Easiest case example. When my 370 goes into this frustrating 'mode', doing 90km/h (55mph) on the Freeway in 6th gear and flooring the pedal (WOT), if you have the ability to monitor both the Pedal Position and ECU Throttle Position (I use DashCommand on an Android tablet and Bluetooth OBD2 adapter), the Pedal Position snaps to 100%, yet the ECU Throttle Position does not, instead it will hit approx 35-40% and slowly increment (you'll feel the power slowly kick in over time while at WOT) as my speed rises until I'm doing about 130km/h (80mph), and
then the ECU Throttle Position will end up matching the Pedal Postion. This is not the case shortly after start-up when the Pedal Position & Throttle Position are nearly 1:1.
Second case example. Taking off from a stand still in 1st gear. As you take off you feel that massive gap of power even when flooring (WOT) the pedal. If you could monitor Pedal Position & ECU Throttle, you could see that Pedal Position is at 100%, while ECU Throttle Position is at 20-30%, and
then after about a second of delay, quickly ramps up to about 80% (this is when you feel the power come back), and the car starts to move properly again.
The system mentioned above is installed between the Pedal and the ECU. It interprets the signal from the Pedal and adjusts it based on what mode you put it on. But it still is not addressing the cause of the problem, the ECU limiting the throttle response, all it is doing is manipulating the Pedal Position signal.... your foot can do that. It would not solve the problems above in any way whatsoever.
I am not saying they do not work. The principle behind them is valid, but with regards to this particular issue in our cars, they will not resolve anything. If the car was working normally and not suffering from these problems and you installed one of these systems, yes you would notice a slight difference in response. No power increase, just response, (and again, nothing your foot can't do).
