sorry, this is no direct OVMS issue, but as many
Twizy users seem to read here, this may be the
fastest way to spread this news.
Renault have disabled tuning on new Twizys.
This applies to Twizys manufactured after June 30
2016, variants T45 & T80 have been confirmed,
Cargo most probably as well.
To check your SEVCON firmware, do these reads:
CFG READS 1008 0
CFG READS 1009 0
CFG READS 100A 0
CFG READ 1018 3
The new SEVCON firmware version is:
Gen4 (Renault Twizy)Thu Jun 30 18:21:36
CANopen (Object Dictionary) revision:
The effect is, that any write access to some
tuning register will result in a CANopen general
abort code 0x08000000.
Write access has been blocked selectively to just
the driving profile registers. Login level still
is 4 and other writes succeed, DCF download works.
The blocked registers have not been changed in the
object dictionary, so this is a hard coded handling.
I currently don't see any way around this other
than reflashing the controller with a previous
firmware (which has not leaked up to now and
cannot be read from the controller).
Of course this not only affects OVMS tuning, but
all Twizy tuning boxes.
Only SEVCON tuning (CFG command) is affected, all
other OVMS functions will still work.
Please spread this info to your local Twizy
