Punch Continuous Variable Transmission (VT2/VT3) Clutch Adaptation Procedure

INITIAL ADAPTATION (FACTORY/TECHNICIAN)

In order to compensate for the manufacturing tolerance, an initial adaptation for the clutch is required after:

• a reflash of TCU software
• replacement of TCU, or
• a replacement of the transmission.

The CVT check light flashes once every 2 seconds if the initial adaptation is not performed* (read foot note below).

PERIODICAL ADAPTATION (USER/TECHNICIAN)

The TCU keeps adapting  to compensate for the wear and tear as you use the vehicle.
However, due to the rarity of using certain drive modes (i.e reverse), the TCU may not be able to adapt to every drive modes.
This may result in the 'engine die off' issue while reversing, due to poor clutch lock-up.

Users can perform the following adaptation procedure periodically to compensate for the wear and tear due to usage.

Adaptation can be performed without additional equipment.

CONDITIONS

Throughout the procedure

• Vehicle being stationary
• Accelerator pedal is not applied
• Stable engine idling speed
• Stable and warmed-up CVT fluid temperature
• Foot brake is applied

PROCEDURE

1. warm up the engine and transmission
2. shift to Neutral (N) position for ≥ 5 seconds
3. shift to Drive (D) position for ≥ 5 seconds
4. shift to Neutral (N) position for ≥ 5 seconds
5. shift to Reverse (R) position for ≥ 5 seconds
6. repeat step 2 to step 5 for 20 times* (apply foot brake throughout this stage)
7. shift to Drive position
8. gradually accelerate to >50km/h
9. gradually stop the vehicle
10. complete

*if only the transmission is replaced, the CVT check light wouldn't flash, hence the need to repeat the shifting 20 times to make sure that the adaptation is completed. If the CVT check light is flashing, the procedure can be stopped once the CVT check light has stopped flashing and turned off.

UPDATE #1: it has also been reported that a long period power disruption to the system may cause the TCU to loose the adaptation data, hence the need to readapt it before the vehicle is driven. This is to prevent unnecessary wear in the transmission and certain drivability issue due to poor clutch engagement especially for vehicle with high mileage.

UPDATE #2: long term power disruption may cause the CVT check light to trigger once a new battery is installed. In the case that the CVT check light doesn't go off after this manual adaptation procedure is performed, send the car to the nearest SC to clear the warning.

Proton Preve CFE - Bosch GPS - KOYAK!!

Sri Iskandar township in Tronoh came out blank

The Preve CFE comes with in car Bosch GPS.  It is part of the HU unit comprising of the radio and media entertainment system.

For information I also been a regular user of  GPS software on my hand phone.  On my old Nokia E73 the GPS software is Garmin XT while on my Galaxy Note is Papago M9, NDrive and Waze.

Comparing all these GPSs I must say that the Bosch GPS cameout very poorly and the best is still the Garmin XT on my old Nokia.

The bosch GPS comes with big limitation because it is using very old Malaysian map.  A lot of places came out blank on the GPS especially new roads and housing estate.   GPS is about having the latest map and good routing software.  Even though the map is stated as version 4 and dated Dec 2012 it is actually very very old map.  If you are a regular user of GPS you will instantly noticed it.

How I wish the Bosch GPS  systems is compatible with maps produced by MFM maps at http://www.malfreemaps.com/.  The maps produced by MFM is collaborated by other GPS users.  It is almost daily updated.  You cannot beat that.  Both Garmin and Papago users benefitted greatly from this.

Further more, the maps on the Bosch GPS is a a closed system and cannot be updated by users and have to be updated by the manufacturer.  This make me really wonder whether the fella who decide on this in-car GPS unit really review out the system properly from user's perspective.  To me the in-car Bosch GPS system is a botched up job as Proton has the opportunity to make Preve a more complete driving experience.

Update PREVE GPS - BOSCH Navigation

This POI only for Preve CFE that have Bosch HU.
Step 1 : Download the file it
Step 2 : unzip the file it
Step 3 : empty your USB driver and copy the whole file name "myPOIs" to your USB driver
Step 4 : plug your USB at your HU USB port
Step 5 : HU will automatic detect the POI file, Wait until complete.

------------------------------------------------------------------------------




1. Extract POI file from .rar file in your computer (see above).

2. Insert in your flash drive to your computer and format your flash drive using a FAT32 file system.

3. Copy the myPOIS folder which you have extracted earlier to your flash drive.

4. Eject flash drive device from your computer.

5. Connect your flash drive with your POI data to the USB port of your HU.

6. Switch On your HU before doing step 5

7. A menu will pop up automatically asking you to download the POI data from your flash drive to your HU. Choose 'YES' to download.

8. If step 7 does not happen, you have to go to Setup button at your HU, then tap Navigation and tap the Download my POIs now.

9. If 'Download my POIs now' option are not highlighted on the HU, that means your flash drive is not readable. You have to choose a different flash drive or redo again from step 1.

10. The POI data will be downloaded to the HU now(assuming all step above successful)


*HU = Multimedia Compact Player / Radio / GPS.

To convert GPS to various format

I use GPSBabel, a FREE software to convert between various gps formats.

link: http://www.gpsbabel.org/

1. .gpi convert to .csv
2. Open .csv in excel to do some editing
3. Save as .csv
4. Rename extension .csv to .asc
5. Transfer to GPS HU in Preve

------------------------------------------------------------------------------------------------

Copied the latest AES location from malfreemaps.

Convert the GPI file format (Garmin format) into ASC with GPSbabel.
Should work nicely with our Bosch HU unit.
Just a sharing of what I found.

YES Account for Proton Preve

Here is the conversation....

let me repeat again...if u finish RM60 in less than 1 month duration (billing cycle) and u want to keep using the service,then u need to reload. if u do not fully utilized that RM60,the balance will be carry forward to next month.

u need to calculate how much u will be using.if more than Rm60,i strongly recommend u to straight away topup another RM10 so that u can get total Acc Balance more than RM68. with that credits,u can use to purchase Valuepack 68 worth of RM68....with PAYU,RM60=2GB of data only....with Valuepack 68 u get 3.5GB data+150min free call+150free sms...see the differences?

-----------------------------------------------------

Better to top-up RM10 monthly to enjoy 3.5GB data+150min free call+150free sms
