Fuel economy - shift points and right gear to cruise in

Fuel economy - shift points and right gear to cruise in
Just curious if anyone knows how to drive our cars most efficiently. 5-speed F22/F23.
1) When accelerating, what RPM is the best to shift in each gear?
Shift too low and it's terrible for fuel consumption since the engine is very inefficient at the low RPM. I tried shifting at 2K and it sucked ass. Slow and bad fuel economy.
2) When cruising, above what speed does each higher gear becomes more economical than the previous one? E.g. I am going 40 km/h and I can't go faster (traffic or shitty road or something else). Is it better to be going in 2nd, 3rd or 4th gear? Car can drive in all. Or going 60 km/h. Is it better to cruise in 4th or 5th? Etc.
When I first got the car, I was getting 9.3L/100 km (25.2 mpg) but I have recently improved to as much as 7.3L/100 km (32 mpg). This is around 90% city driving - we don't have crap for highways around here.

Also the owners manual as some pretty conservative suggested shift speeds. Which would be good to look at for conservative acceleration.
Recommended Shift Points
Shift up - Normal Acceleration
1 > 2 15mph(24kmh)
2 > 3 28mph(45kmh)
3 > 4 41mph(66kmh)
4 > 5 52mph(84kmh)
Generally if I'm driving 40+ and just maintaining speed I'll be in 5th.

the fuel consumption ratings for the 2.2 5spd when it was produced are 9.5/7.0 for L/100km in city and highway driving respectively.
...and your getting 7.3 in mostly city, i'd say that's really good, or as good as you're gonna get especially with a car that is over 10 years old
I usually shift between 2.5k and 3k depending on the gear i'm in, the lower the gear the higher the rpm, but i don't get the mpg that you're getting
I've also wondered if it would be fine to cruise at 65km/hr in 5th.. i usually just shift into it around 75 anyways

How many RPM's are you guys cruising at 60 mph in 5th?
I'm tempted to swap transmissions in my H22 Prelude, it (still) revs quite high at 60 mph and quite frankly it has more than enough power

cruising at 60 in 5th is about 23-2400, i feel like its too low at that point. like im stressing the engine. i tend to drive with 2600 being my lowest point, which is about 65mph.

I am hypermiling so the stock values in the manual are just something to beat. It's easily possible to get way better than the advertised mileage if you know what you are doing. It's not as if I am going out of my way to keep my fuel consumption low. It's just that you can't go fast around here anyway
I guess no one has a specific answer, so I'll try asking on the ecomodder.com forums. I'll report back if I get anywhere with this.

Not sure really, I was just curious. I know the transmission from the F22/F23 swap. I get a respectable 27 mpg on the highway at 65 in this Prelude (its a '91 with an H22), I definitely enjoy the fact that in 5th gear, it has plenty of power even in the mountain passes.

instead of posting a new thread. I dont know about yall, but i leave my car in gear when i park. seeing as my passenger side ebrake assembly's spring is shot to shit, ive got no choice.
i met a kid who leaves his car in reverse as opposed to first. does this matter at all? is there any difference? i wanted to call the kid a dumbass, but i dont even know..

I shift when I feel like i've achieved the needed amount of power for that gear, very road and traffic depended.
If going uphill, i'll shift at 3.5-4
downhill, 2.5-3
sometimes i shift at 7.4

The only advice I could give 3.0ers is keep it in D3 for stop and go if your under 50 mph but over that, put it in D4 when crusing or else you will be crusing at way to high rpms. I could get 24 - 25 mixed mpg using this technique which is pretty good for the J30. BTW, the car is more reponsieive in D3 since it shifts through less gears. Give it a try.
