it should not change much.... if his ori is 15" 195/50 upgraded to 17" 215/45 the speedo should be +5km/h only

FYI 195/50 on waja the speedo shows -10km/h

for waja with 17" 215/45 should be as accurate as GPS.... trust me coz im using military MTK 15hz real time GPS logger for my carpc.

stock rims and tyre always incorrect... it's -5 to -10km/h diff.... you also cannot define the front car speed by chasing because by newtons laws the variation speed cannot be seen when you are behind the car due to co-drag efficiency unless you both at side by side.

stock cars always have "+" speed as a standard safety feature on commercial vehicle.

sorry... just now all the comments are terbalik hahahaha

stock cars tends to be faster on speedo by 5kmh to 10km/h

i always do reverse engineering

Lights measured by lumens not K... K is kelvin where it is light temp colour. The best visibility of lights tru naked eyes is 4800k

The GPS you can buy from ebay aviation GPS module, it runs on TTL data where you need to design a circuit board to translate the TTL NMEA data to 232 Data via FTDI drivers. not all GPS support 15Hz because and comport RS232 had its maximum duty cycle too where you need to select properly all the config else it wont works. Aviation GPS is very powerful even indoor it will try to use others signals to triangulate.

i have another one where i posted in Waja V11


Something to share with u guys.... a bit off topic here hahahaha

Okay.... i just found that we can reprogram GM-2 GPS become military spec.... accuracy from 12" to 2.5 meter..

1st get a iBlue GM-2 (not china GM-2)

Download GPSview 1.2.1 to program your GPS to 5hz

Note Garmin do not work on this unit if the baudrate is higher than 38600. The higher frequency the smoother it goes...

Connect the GM-2 and install the driver....

Fire up the GPSview

Follow the settings above

All is in $GP

GLL - Lat/Lon data
ZDA - Date and Time
GGA - Satellite Fix information
MCHN is a MTK NMEA sentence which shows the internal status of gps channels
GSA - Overall Satellite data
RMC - recommended minimum data for gps
VTG - Vector track an Speed over the Ground

The setting 1-5 is the frequency of data in sec. some set 5 some set 1 this is because i dont want to overload the data to RS232. Now the duty cycle should be 82%... dont try to push it to 100% else u will have a 232 crash and you have to recover the GPS using others software to init back the bootloader.

After setting.... click on the DGPS apply.. you will get WAAS Enabled....
WAAS is a GPS assistant which provide more accurate signal even indoor.

Follow all the settings above and click apply.

After u program it correctly, u should able to receive GPS indoor. (depends)

Yup coke is the best cleaning agent for corrosion thats why i like to drink.... it cleans my body like threebond.

coke.... just drink it and shut up

the brand dosent sound good.... i use Shell ATF is the best....coz i have done load chart test.... the most less load is the one shell dunno what ATF later i check back my auto log book then i tell u.

stock still the best for everything including wallet
