New Instrument Panel Install - GS911 recode?

<< < (2/2)

WayneC:
If Koso has managed to reverse engineer the CAN comms properly & has an install routine where you ender the ODO value then perhaps that aspect would be covered however it will be only by fitting one that the lessons will be learnt, see if Koso has install & operations manuals & if so read them. Note that reviews are unreliable

WayneC:
I took a look & the Koso Instruction pdf section 5-12 page 19 seems to explain the ODO aspect

They use the terms Internal & External ODO, a round about way to explain anti tamper backup in ECU's so the backup is "Internal" & the Koso is "External", there are 2 lines of text in the instructions which are relevant

1/ User unable to adjust or clear internal ODO.
ie you cant change the backup value in ECU's

2/ When connecting to the meter for the first time, the total external mileage displays the ODO record value.
ie the Koso reads the ECU ODO value & sets "External" Koso ODO to the same value

You can only assume Koso has reverse engineered the CAN comms to have the ECU ODO values updated as per BMW dash

The ability to increase the "External" Koso ODO value will be as per the Dealer System ability to correct any mismatch in ODO values & only allowing an increase in value is appropriate to stop total ODO value tampering
