My tachometer reading is as follows at cruising speed.
80km/h - 2000rpm
90km/h - 2200 rpm
100km/h - 2400rpm
Some forumers claimed that their tachometer reads 2000rpm at 100km/h.
What is your reading tachometer reading at the above speeds?
*Note : Each small mark, ie. " - " above the 2000rpm mark represents 200rpm.
-
CVT and 4AT have different Tacho Reading so son't worry about it, your's will be common to that of the 4AT Gear Box
-
Yap, Jef is correct. For 4AT gearbox, the rpm is higher than CVT gearbox. That's why some forumers claimed that their tachometer reads 2000rpm at 100km/h is correct for CVT.

am on 4A/T, the rpm is correct.

Bro,
mine's a 4AT too..
so 100km/hr will be ard 2400rpm..
:thumbsup: :thumbsup: :thumbsup:

Hi,
I think the tachometer reading depends on the gradient of the road that you are driving and how fast you push the car to achieve that speed.
On a flat road, if i drive gently and let the speed increase, I can achieve 100 kmh at 2000 rpm.
-
You mean you managed to cruise on a flat road at at 100km/h at only 2000rpm on your Latio 4A/T? :w00t:
How did you do that? :confused1:
No matter how I tried, no matter how gently I stepped on my accelerator, my rpm still showed 2400rpm at 100km/h
-
the readings are right for the speeds you mentioned. For 4A/T only though. I add one more
at 120km/h, abt 2.8-2.9k rpm.

4AT??? Impossible..... even if u let go of the accelerator....

I noticed that at speeds above 80km/h for Latio 4A/T on overdrive, the tachometer increases 200rpm for every 10km/h gain in speed.

His ride is CVT lah. Never check frequency before using radio how to get 93.3 programe at 95.0FM :D
-
Mine CVT, 100km/hr at 2200rpm leh, 90km/hr at 2000 rpm. How lightly i press accelerator also, the readings remain as such. My CVT different ratio arr ? Mine is Oct 2005 model. Maybe later models different ? :confused1: :confused1: :confused1:

izzit.... his mini info state sedan base model leh :confused1:
nowadays base model all CVT meh :bleh:

Guys, pls do not neglect your rim size and tire profile, all these affect the speed and revolution. :smile:
-
For mine at 80km/h at 2000rpm, 90km/h at 2100rpm, 100km/h at 2200rpm. Driving AT.
-
I am driving Latio 4A/T on stock 185/65R15 tyres, and my rpm is as follows -
80km/h - 2000rpm
90km/h - 2200 rpm
100km/h - 2400rpm
Those of you driving Latio 4A/T whose cruising rpm differs from mine, did you upgrade your tyres and/or rims?
-
izzit.... his mini info state sedan base model leh :confused1:

Didn't look at his mini info, but I'ld like to see his RPM at 100kmh if it's a 4AT.
-

Nope, I don't think there will be a difference in READING the speed on you meter dial when you up your tyre size, it's still based on your standard tyre size unless your car is so futuristic that speed is not measured using parameters preset in the ECU or based on your wheel rotation speed but an external source or you've re-calibrated your meter after changing wheels.
I'm using 205/55/16 and my rpm is still at 2400 when I'm travelling at 100kmh.

me too(https://www.sgnissan.com/forum/proxy.php?request=http%3A%2F%2Fidobaby.com%2Fforum%2Fstyle_emoticons%2Fdefault%2Fph34r.gif&hash=87eaf4535742e8604f6f97d89601167452f2f8eb)

For mine at 80km/h at 2000rpm, 90km/h at 2100rpm, 100km/h at 2200rpm. Driving AT.
You sure bro, your meter dial is 200rpm per mark so at 100kmh it should be 2 marks above 2k so it should be 2.4K rpm. Unless you're saying your meter dial is just 1 mark above 2k when you're at 100kmh.
-
Perhaps he upgraded his rims and tyres to a wrong size and hence his speedometer is giving an incurrate reading - slower reading than actual speed.

Google and read about the tire profile size do affect speedometer reading. The ECU unable to re-calibrate to the new rim size and tire profile for your info. Bear in mind that our speedometer is analog, not accurate to gauge or judge the actual speed or RPM.
Lastly your speedometer reading with 205/55/16 is 1.67% slower compared to your stock size

That is precisely what I'm trying to explain, it shows 100kmh and tacho is 2.4k rpm, I'm going above 100kmh but it's not registered. It just don't show up in your meter dial so it should show the same no matter what tyres you're on. Those 2 figures are constant no matter what rims and tyres you're on unless you go calibrate. So where did the variance come from if every one is using the same gear box ratio and same calculation of tyre circumference.
-
Use the link below to gauge if your tyre and rim upgrade is of the correct size.
If the size is incorrect, you are likely to get incorrect speedometer reading.

:smile: thats is the reason why I always advise my associates when they change their sizes over the 2% mark, against stock.....
the actual speed will not be reflected on the meter.

I manage to get 2000rpm at 100kmh cruising on a flat load without passenger and empty boot. Petrol I am using is either Caltex RON 98, Shell RON 98 or Vpower. Stock rim and tyre.
May be because my car still less than 3 months old.
Haha

Brother follow the link http://forum.thelatioclub.org/index.php?topic=364.0, we're not talking about incorrect speedo reading in the thread here but the relation between speedo reading and RPM reading.
-
An incorrect speedo reading will affect your rpm reading too.
For example, if because of your incorrect upgraded tyre size, your speedo reading is faster than the actual speed by 3%.
Hence, when your speedo shows 100km/h, you are actually travelling at only 97km/h.

wah lao.. den my 4at sounds to love to rev abit more den :crying:
-
yo.. does it mean our 4AT drink more petrol than the CVT version? is the diff in FC big? :blink:
