well i have a stick and what would be the best-performance rpm to shift at while racing? i thank that makes sence but if not i think u know what im trying to say. lol. and what is an ecu reflash rrm?
thanks a lot!

 

Shift points may vary, but I'd say go as close to redline before going. At the very least, don't shift until you're well above 3500 since that's where the powerband generally lies.

The ecu reflash alters the timing and fuel curve of the car to allow for more power. Run a search and you'll get more detailed explanations.

 

Assuming your car is stock, then yeah like ghostrider said, you should shift at right around redline. Of course, if anyone has a baseline dyno along with gear ratio would really help.

 

Actually, my experience is that the Lancer stock loses hp very early, around 4500, so I suggest shifting at 5000 tops. With the reflash, I shift at 6000-6200 which is still 900-700 below the new redline.

Like Ghostrider said, the reflash adjusts the timing and fuel curves to run less lean at the low end and less rich at the top end. The end result should have more power, a flatter power band (the reason for shifting at higher RPMs), and better gas mileage. The first two I have experienced, still paying attention to mileage before making a verdict.

 

Somebody on this board has GOT TO have a baseline dyno... Anyone?

 

Interesting, since the peak power in the stock car is right about 5500 RPM.

Now I hope nobody's running around making EVERY shift at 5000 RPM. During normal driving, there should be no need for such an effort.

 

Horsepower @ rpm (SAE net): 120@5500

Torque (lb-ft @ rpm): 130@4250

That was my logic for shifting at or about redline when my car was running basic bolt-ons. Now my CEL is a shift light set at 6,000rpms.

 

so i guess 5000 rpms is were i should be shifting when im raceing
and my car is stock if that makes a diff.

 

No, not if your peak power doesn't come until 5500. Try redline.

 

is that bad for the lancer

 

Sure. Taking the car to redline every shift is gonna leave you in the shop a lot.

If you race, take it to 5500 or 5600, you shouldn't even need to pull farther if you're stock.

Now once you get an RRM reflash...well that's another story.

 

you should be hitting the Rev limiter as you push in the clutch. There is still far more power at 6300 rpms than shifting at 5 or 5500 and having your RPMs drop to 2500 rpm. you'll bog your motor for about 3 seconds before you'll get back into the powerband. Ive had my car at the track like 10 times and my best ET's are at redline shifts. And with a rev limiter at 6300 you can hit it all you like without really worrying to much.

 

And again, does ANYBODY have a baseline dyno and stock gear ratio? All this discussion is rather pointless without any kind of data backing it up.

 

No. Not that I'm aware of or have ever seen.

 

In Import tuner Buschur racing dyno'd the lancer at 103hp to the wheels.

As for shift points I agree with the people who say for stock you should shift at 55-5600 rpm. Anything near redline risks hitting it and bouncing off the rev limit which will slow your times down.

When I was near stock my best times were run shifting at 5500to5600rpm. Anything above that netted higher trap speeds but slower ET's (total time) in the 1/4 mile.
