I midaswell have my input. I bought my car with a faulty tranny (Who hasnt?) after replacing it, I noticed the power light is burnt out....which explains why the tranny was fried

Hiya,

With your "automatic power function" how long will power actually stay active for under acccleration? is it all the time you have the throttle down or only for a given time?

It seems a curious situation and I cant see any logic or benefit in your system when the JDM had the manual switch to either turn the fuction on full time or off to automatic like yours.

It stays on until you let off the gas, and as stated above once you let off the gas, it will stay on for 3 seconds.

I call it gas guzzler mode and thus I am grateful that I don't have a manual switch (what if I left it on by accident ). I think I can actually watch my fuel tank drain when in power mode. And from my experience, the power keeps giving as long as you keep pushing.
But with gas prices today... only in emergency.. or when I'm feeling rich
Cheers!

WOT? I know I'm going to feel like a dork for asking but..........

Wide Open Throttle.

No worries, it took me a while to figure out what "5MT" meant, and like 2 months to figure out what this "USDM" thing people kept talking about was.

I actually did a comparison. I did one tank of fuel with the power button off and another tank with it on. Surprisingly, I did not find any significant difference. I drive with the power button on all the time, except on long motorway cruises at 70+.

Yeah, Phil, I have posted this a number of times as well. I compared a number of tanks of fuel though, not just the one, Power mode permanently on, or switched off [which was on demand, really ]

I got 2 mpg difference once, but only one mpg difference for two or three tanks. Same as you, I eventually left it switched on, full time.

In fairness to Cosykat, driving a US car or a standard UK car with Power mode on all the time would be very sore on juice!! The only way you can do that is with your foot to the floor all the time. It could be hazardous to your life, your license, your sanity and your freedom [cops would lock you up]

For anyone who has not driven the Japanese model with the switch for turning on the Power mode shift map, the principal difference in driving is the gearbox will hold the lower gears for longer, rather than slipping up into the next higher gear at 1200 or 1400 rpm.

This does not give any magic extra power, as has been suggested in the dim past. However, it does feel better to drive, because the engine revs being higher drive the axles with more torque. As I said, the only penalty [with my driving style anyway] is 1 to 2 mpg heavier consumption.

Also when you go into power mode the car will shut off your A/C compressor to give you the max power it can, it comes back on as you ease up on the throttle. Figure 15HP maybe?

10 maybe, and only if you've got it blasting.

That's a very interesting point to ponder.

In the Japanese ones, even though the car can be driven with Power mode shift map on all the time, the aircon still works and the compressor does its job.

The ECU [rather than the TCU] controls the aircon pump and turns off the compressor when the car is accelerating hard.

So it is probably the case that the ECU turns off the compressor at or near WOT conditions based on preset parameters in the software. It is a coincidence that in the models with Power mode available only on demand that green light/Power mode cuts in for the same WOT conditions as turns off the A/C compressor.
