But you can control your foot to stay in low revs..

That's what I do. Kasi may RPM requirement din ang manual mode para mag up-shift..

I'm not that sure, kasi kapag naka manual mode ako sa asx I can up shift gear kahit nasa 1300-1500rpm lang ako or lesser.i think di na sya manual mode kung kailangan pa ng rev requirement, kasi ganun naman manual trans, shift whenever you want to shift gear.

[tidus1203]

Even if it means the engine dies? May requirement yan the tranny will not allow you to manually shift on a RPM that is too low that it kills the engine...

So far its the latest trend of engine today of BMW, Benz, Nissan-Renault, Mazda, Ford Ecoboost, GM Ecotect & lately Toyota has announced to adopt gdi on 2013. Mitsu & Honda, no news.

I think its not just a trend but rather it is for compliance with the EURO-5 and in preparation for the EURO-6 exhaust emission standard. This could be the main reason why European manufacturers are now all adopting the GDI technology.

Is this GDI reliable engines??

In terms of lowering exhaust emission, yes it is reliable especially if the system is brand new, it can easily pass the test and inspections of the authority.

But in terms keeping the engine running at all times (when the car is in use), hmmmm GDI technology rely on solenoid valve (open/close function). Solenoid valve has a useful life of let say around 60-100 million times of open/close function. If we only know the designed useful life of the valve, math can easily estimate when will the valve is about to fail.

For example: If 1RPM=1 opening of valve, and if the engine has 4pistons/4valves this means if the engine is running at 4000RPM, each of the 4 solenoid valves have opened and closed 1000 times in 1minute.

Therefore at 4000rpm average engine speed:
For 60,000,000times(life)/1000= valve life-ends in 60,000minutes or 1000hrs.
For 100,000,000times(life)/1000=valve life-ends in 100,000minutes or 16++hours.

If the car average cruising speed is 60kph the car could travel 60,000km before the valve starts to fail. If 100kph it will be 100,000km.

Over the 100,000km most cars has no more warranty.

I did not say 0(zero) REV or RPM, I said LOWER REV or RPM. Sa 1300 -1500 rpm ba namamatay engine mo pag nagchange gear ka?i dont think so. I think we dont have the same experience cause we use different cars or probably different engine size.

Manumatics are still on active watch mode even if the driver shift the stick to manual (+/-). Although the system waits for the driver's next move, anti-stall control will automatically down-shift the transmission once the engine rpm is near the idle. Also the system will automatically up-shift once the engine speed reaches the critical point or reaches the predetermined up-shift points.

The up-shift points during the manual mode might also be similar to the up-shift points of the "Ds" mode

Ds is Drive Sport mode with a new settings that may double the engine RPM on each up-shift compared to the normal up-shift RPM of the "D" mode. Ds mode is useful when overtaking and going up and downhill.

"anti-stall control will automatically down-shift the transmission once the engine rpm is near the idle"- I would agree on this part, but "up-shift once the engine speed reaches the critical point or reaches the predetermined up-shift points"- I dont think so. Basing from my experience, at manual mode, there is no system intervention. I think better remove manual mode at all if the system will interfere at that mode.

We should remember that manual mode are installed for us to experience manual transmission even though we have bought an automatic tranny vehicle. So far I'm satisfied with what the asx CVT is capable specially at sports/manual mode.

Critical point and predetermined up-shift points is usually a function of RPM over a particular period of time. For example if the critical point is 6000rpm it doesnt mean the tranny will automatically up-shift once 6000rpm is reached.
Time or time-delay is always added otherwise the system will operate erratically.

Try to exceed the red line and stay on that RPM longer or rev the engine even further for 1minute or longer and observe again.

Ok men..I got your point..its a protection for your engine..I think all of us know that if we stay at high rpm could cause for engine burnout and doing it can cause higher fuel consumption.

This is the mode of operation of the Mitsubishi CVT/Jatco JF011E

When the mode is changed to the manual/sport mode using the paddle shift during automatic gear shifting, the manual/sport mode is cancelled under the following conditions.
• The upshift lever of the paddle shift is pulled for 2 seconds or more.
• The vehicle is stopped.
• No operation (no driver intervention) is carried out for 4 minutes and 25 seconds.

This situation happens when you use the paddle shift to change from auto to manu, these really happens mainly because you have bypassed the system and will return to "D" mode if no operation was made after sometime,but if you use the stick to change from auto to manu mode, different situation happens.The tranny is really in manual mode and never will it go back to "D" or "auto" mode even if the vehicle stops unless the stick is returned to "D".The gear will only go back to "1" or first gear as indicated at the instrument panel. I dont know if you have experience changing modes using the stick.

Nga pala...sa may mga asx...just now, I saw at the back of our rims na they were made and designed by Enkei. Share ko lang po..

Its hard to explain against your actual experience but I think its not.

The display may stay on manual mode but remember that the tranny is a CVT. there is no actual change of gears. The tranny can change that pully ratio softly/smoothly without the driver noticing it.

Would you like to try the earlier suggestion? this time staying in 1st or 2nd gear at over 6000rpm for a couple of minutes? And observe? Maybe you might wonder how come the car managed to gain speed of over 100kph and even continue to accelerate further? Its because the CVT has fail safe function that prohibits the sport mode and the TCM take-over the control as D "auto" at the speed of over 70kph with constant accelerator pedal angle and RPM of near or over 6000 for a period of time.

The stick and the paddle shift are the same. Their electrical connections are parallel. When you slide the stick from D to +/- its the same as activating the sport/manual mode using paddle. When you pull then hold the + paddle for 2secs or more its the same as sliding the stick back to D.

Everytime you slide the stick from D to +/- gate and back, you are hitting/operating an electrical switch in the selector lever assembly.

Im not sure if I can do what you want me to do, cause we started talking on how to improve FC and ending up revving up to 6000rpm,it doesnt make sense...... Are you using a Mitsu with a CVT? cause as for me, im talking through my experience.

What I suggested is just an experiment, basically a one time experiment to verify that "Ninja" like actions of the CVT.

Once high rev and large accelerator pedal angle is observed by the TCM for a period of time, the pulley ratio should be automatically and slowly reduce thus the car speed continue to increase in whatever gear is displayed. These actions reduces the tension on the steel belt and it also create a constant wear (or evenly distribute the wear) on the surface of the pulley.

Staying in one pulley ratio for a long time or most of the time is bad for CVT because it creates deep marks on the surfaces of the pulleys. Deep marks and scratches on the pulleys will make the CVT no longer as smooth as before.

One possible explanation why the system has to display the same gear number even if the "auto" mode is taking over is: Imagine this scenario, you start using the manual/sport mode for the first time while driving alone at the middle of the night. Nagmamadali ka dahil hating gabi na kakatakot sa daan sobrang tahimik. You read from some websites that once you are in manual mode it will stay in the same gear number as long as you do nothing but then you noticed that the gear number changes without your intervention at alam na alam mo nakamanual ka. Di ka kaya mayat-maya tingin sa stick baka may ibang kamay na gumagalaw? Or mayat-maya tingin sa rear view mirror kung may nagmumulto? hehehe just kidding.
Whereas if you notice that the speed is increasing, you can just ease your foot and feather the accelerator pedal to reduce speed and be amazed that such low gear display reaches high speed.

I have sir a copy of the technical description of CVT with 6-speed sports mode for 2.0L 4B11. Although the wordings are not complete, there are isometric figures, cross-section views and graphs to look into that can be easily put into words.

I think I will not risk my new engine for your experiment.hehehehe.. maybe you can send me a copy of your technical description for me to study. thanks for the information by the way.

Hello,

New to this AVT navigation thing of the ASX. I just checked the website of Inav.ph and saw an new update for the Head Unit of the ASX. I tried to download it and ran but i get a CRC error every time. Anyone else got this problem?

Didn't have any problems when I updated my SD card. Did you download the right file? It's ... MMASX.

[big_d_lou]

Yup i tried it 4 times. I will try it on another computer.

EDIT:

I'm still getting the CRC error. How big is the file you downloaded? The file that I have is just 39.8 MB

[arsen]

You can refer to this Mitsubishi F1CJA-CVT. Its a short version or maybe a public version of the document that I have.
