Do you think it is good idea I visit that SC again and talk to that SA face to face and ask him ALL my questions?  tongue.gif
I guess they can check their computer and the record should be in there?

Another option is to go straight to EON Sg. Pinang, they ask them to check ECU/TCU version and order recall parts. Do you think they will entertain me if I did not service my car there before?  blush.gif

it is worth the whole while i waited for more than 3 hours to do ecu/tcu remapping...

before i forget, in eon penang, u will see they use sagaflx ecu, i asked the technician there, he said its typo...

difference:
1. in D mode, press brake fully stop, the rpm maintain the same, at 600 or 700 rpm.
2. in N mode, the rpm change, at 900 rpm...
3. new ecu/tcu change the second gear issue, which it will rev up to 1.9k or 2k rpm then drop back to 1.5k rpm...
4. car ady move quite fast in 1.3-1.5k rpm, compare to previous tcu, car only move quite fast during 1.6-1.9k rpm...
5. can just maintain rpm around 1.5k rpm for 50-80km/h driving in town, compare to previous one, need to maintain around 1.7k rpm...
6. in D mode, after gear engage, the rpm will rev to 1k rpm to move, compare to previous one, rpm at 900...
7. feel like current tcu/ecu setting like put in S mode, very responsive...way responsive..

assumption based on my observation:
1. fc will be better...
>> for past two days, i tried put in D mode, then observe the "instant" in SID, from idle to start to move the car, it need about 99l/100km to move car.
>> now, new tcu/ecu, just need about 40l-60l/100km to move the car.

After ECU & TCU update i encounter this. When i on reverse gear "R" suddenly engine off. I have to start the engine back and reverse again. After that no problem when using "R" gear anymore. (hopefully)  cry.gif  cry.gif  cry.gif

i have mentioned the probability of this problem... sweat.gif

Hi Arthur, what do you mean we can "see" those?
I thought remapping ECU was simply re-flashing the chip?

Although I do not have exact comparison numbers, but I really do noticed the Instant FC number are lower when driving at about 40km/h to 80km/h regardless what is the RPM. But this will not make the average FC goes down because it's so pleasure to step on the pedal to feel the power.  laugh.gif

One thing not sure if related to your difference 3. that second gear rev up then drop back? For my car, when launch from standstill with about 50% pedal level, the car (or the rpm) seems to go up and down with a rhythm but not gradually going up or maintain at any rpm. It's quite hard to describe, wish I can attend next TT so I can let you test drive mine.

they use a laptop to do those remapping ma...they will choose ecu file...
what i'm saying here is observe it, make sure it is that file, unless they correct the typo...


in old tcu/ecu, from stand still, at first gear, the rpm will rev up to 1.5k or little bit more rpm then drop....
then (assume its 2nd gear), the rpm will rev way up to 2k rpm or 2.1k rpm..
then 3rd gear, the rpm will rev up to 1.5k or a bit more then change gear...and so on....

from the first gear to 7th gear, only 2nd gear significantly rev up so high...
but in the new tcu/ecu, we will no longer see this "fluctuation"...
it just smooth all the way between 1k rpm to 1.5k rpm....of course unless u press so much until 2k rpm...

now i have to be careful with my right foot, why? cause, before this, light foot become heavy foot now...need to be more light...


another important note, even u pedal hard (within 2k rpm), the "instant" fuel comsumption will around 20-40l/100km...
compare to previous tcu/ecu, the "instant" will be 40l/100km onwards...

Thanks mat79 for the background info on the various partners involved in developing Preve. Proton should actually advertise and promote this rather than saying that it is a global car. Make it the buyers feel that it is worth the money. Still the specs and pricing is still better than competitors.

I still think having leather seats would be good (do not think people will mind paying extra for the premium variants because it is worth it). I think no reverse cam and having better HU is also to cut cost.
