Normal & Power mode

[Toehead69]

For the 90 through 94 Eclipse/Talons that little Normal and power button on the A/T shifter, is that an overdrive button or is that just to get more power-->> if it is to get more power does it come with every Eclipse/Talon model (base models, GS, GS 2.0, GS turbo, GSX, DL, ES, TSi, TSi AWD. If not which models come with it standard. Also on the 92hp models does that have alot of effect or just a little. Any answers would be great.
Thanks

Im not sure bc i have a 5 spd but on some nissan autos there is a switch that is for power shifting it it just wont let the car shift until it gets to higher rpms, but it may be something else. just me 2 cents

In my car that button says power/economy. When the button is set to economy the car upshifts sooner in the rpm band and will NOT down shift under light loads as easily as when it's in power mode. I have driven my car in both modes through full tanks of gas and the economy setting doesn't get me any better milage during normal daily driving.
I look at it this way, if IM going to be going on long highway trips with minimal inclines i'll use the Economy setting. If im gonna run around town and do some "spirited" driving i'll use the power setting.

"Changes the shift points the transmission uses - that's all. Mitsu recommends that the economy setting not be used except over 50 MPH, to avoid unnecessary wear and tear on the transmission. See Club DSM Automatic for more information."

Just read the 1000 faq's and to my surprise it DOES say that mitsu doesn't recomend economy mode except when over 50mph. The only reason I could think for them saying that is that under 50mph in economy mode it doesn't take too much throttle to cause a downshift which means another upshift and so on.
Personaly, I keep it in economy mode all the time and when I want to hold a gear I manually shift it to that gear and upshift at the point I want to. The same for downshifts. I strongly caution on doing this without using a lot of common sense though. ie; downshifting from 4th to 3rd at 90mph = bad news as does holding a gear to 9000rpm

If you're easy on the throttle around town the economy mode should help your mileage a little and since you won't be running the rpms as high before every upshift your engine will be doing that much less work.

As far as providing more power that is complete nonsense -- like it was already said it only changes the shiftpoints and is not some magical HP button -)

Actually, in a roundabout way, the Power mode does create more horsepower. The 4g63 doesn't make peak horsepower until about 6300-6500 RPM and in Economy the motor won't rev past 6000. So yes it does make more power, but not any more than the factory horsepower.

Peak HP at 6.5k rpm? I think that really depends on the turbo. In general I seem to recall the stock turbo making peak power at 4-5k rpm.

Oh and 91bomb, you can't hold a gear to 9k rpm...you'll hit the rev limiter way before that . You could however downshift the motor to get past the rev-limiter...

I was talking about the 4g63 N/T in my post. Yeah, the turbos do make their horsepower at lower RPMs but the N/Ts are really peaky.

Hi Brad,

It's nice to see you on the forum once in a while.

According to Motortrend's 1992 'Bang for the buck' issue the '92 turbo 5-spd dsm's (they tested all 3) hit peak horsepower at between 6200-6600. For some reason the peak HP numbers were varried. They tested an AWD Talon, FWD eclipse, and Fwd Laser along with about 7 other cars. The Laser finished #1.

Stock Hp is definately at least 6000 or higher on turbo auto trans models too. I used to
run my stock 1g talon to redline in 1st gear until I realized that after about 6400-6600 the car ceased to pull strong so I now time my 1st gear shift (when manually shifting) for about 6500rpm. Revving to redline when your engine has basically run out of steam at 6500-6600 will only wind up hurting your acceleration times and unnessasarily stressing the engine, IMO.

Hmm...maybe...I was probably thinking peak torque .

I don't agree. It also depends on where it drop you on your RPMS after the shift. You want to be right in your power band after a shift.

I agree with this. My 1g turbo A/T w/13g pulls strong up to about 6500 in 1st gear -- so I time my 1st gear shift for 6500 and in my case I am strong in my power band when I hit 2nd. This is the case with the very few mods I have. If, for example, I was running a 14b w/cold air intake and higher boost then I'd probably be running higher rpms in 1st gear.
