Hi!
1.0.3.1 version was made for my tests with alternative scales and manual creation of it.
Purpose of this work was remaking miles clocks to kilometers clocks with reduced speed limit. For example, 160 km/h for Passat an 180 km/h for CC boards.
Remaping table values is simple: divide speed value to 1.603 to get speed in km on the same arrow position.
Here you can see the table and graph:
I used 3C8 920 970 E panel for tests. It is 24C32, diesel, 180 miles. Scales from another dashboard with the same calibration.
Сlearly, i got flashing Error on mileage place due to speedometer control sum. But i went to natural test.
In collage bellow you can see, that Cruise is active on all photos. I check speed by:
-arrow on right dial;
-digital speedometer on the center;
-cruise control digital indicator;
-car speed on head device, got by CAN-bus;
-GPS data on head device.
My wheel is bigger, than factory recomendations, so usually i have no diffenece with GPS data and digital speedometer data (max 1-2 km/h) on regular 260-km/h board.
Test shows, that digital
cruise speed, CAN speed and GPS data is the same. Digital speedometer data and arrow is the same too - due to changing main speedometer table on EEPROM. But on different ranges cruise and speed data are different:
-up to 30km/h speedometer date are smaller, than cruise and real speed;
-from 30km/h to 115km/h speedometer and cruise(real) speed is the same;
-from 115km/h speedometer data are smaller, than cruise and real speed.
So, even if you vin speedometer data control sum, you can not get correct speedometer without changing dashboard software. And getting correct work in km/h with miles dials is nearly imposible.
Next my experiments would be reflashing miles dashboard with km/h flash and get it work with normal full speed limit (260\280). But it would be with Odis-E, not just VDO Editor.
