Highway Driving in 'M'

[Bogus]

Hm I will try that.

All you guys need to get tuned the trans tune fixes the hunt these cars have i rarely use m mode anymore

What he said..

It's not unusual to feel the car jerk. I usually shift at like 2k-3k.

You guys shift at some incredibly low points in general aside from 1st or 2nd gear my shifts are around 4500-5900rpm

That is seriously late. When I'm driving conservatively, I always shift at or before 2k rpm (1.8L 5MT) except for first gear. Gotta save me some gas!

I could be wrong, and someone will correct me if I am... but from what my Ultragauge instant MPG tells me, it doesn't really matter what gear you're in or where your RPM's are, it's how far you're pushing the pedal down.

I can be redlined and get 40-50+ MPG if my foot is off the pedal. So to me shifting early doesn't make a difference, so long as you're light on the pedal all the way through the gear.

i periodically switch over to M mode just to know that it's still there. sometimes i even drive in M mode to see if other ppl notice a difference.

I thought I read in the owner's manual that you shouldn't shift to "M" from "D" when moving... maybe I'm wrong but I thought it said something about the car losing control? Maybe I was dreaming lol..

Yeah.... No.

 

[Bogus]

No lol you can go between D & M all you want.

If I remember I'll try to find what I read tomorrow..

This is not what I've observed with my scangauge. The instant MPG readings I see show that being in the highest gear you can will always give the best MPG, no matter what.

Even if that means having to press further on the gas due to a higher gear (lower RPM), or making more boost in a higher gear (lower RPM), a higher gear with lower RPMs always shows better MPG.

 

[Bogus]

That's cause you're turbo. In my N/A a lower gear with less throttle and higher RPM gives me better MPG. I can try to record a video for you guys.

 

[Stew]

We should both do that, not to try and prove each other wrong, but because the topic of MPG comes up so frequently. It could be helpful to the guys (and gals) without one of these kind of gauges to maximize their MPG and see for themselves how gear selection, load, etc makes a big difference.

 

[Bogus]

Yeah I agree good idea. I'll be going for a drive sometime today. I'll do it then.

The beauty of vvt

The beauty of vvt

vvt?

 

[Eric Smit]

variable valve timing.

 

[klb1.8]

You basically maybe at 4k but not quite hittiing the pedal but once youre more into it that 4k with the tps and phaser opened up basically vtecs. It seems to work best in mode or straight manual

I would just like to add a note that VTEC and VVT are two very different things.

 

[$ub$onic]

Isn't vtec a cam lob change a Vvt just shifting the whole cam
