OVMS: Renault Twizy User Guide
Macro commands
Macro commands are shortcuts that simplify tuning by automatically modifying the set of
registers working together for a certain tuning function. All macro commands check their
parameters for valid ranges, to avoid faulty configurations. Macro commands can easily reset their
parameters to the default configuration. They also automatically switch into PRE mode and back to
OP mode as necessary, so you just need to issue the macro command itself.
All macro commands work identically for the 80 kph and the 45 kph versions of the Twizy,
automatically using the respective limits (see previous section on limit differences). The limits will
be applied on setting the registers, so you can even load a T80 macro profile into a T45 (but don't
expect similar driving results).
Generally, you should have your "Plan B" ready before tweaking. If you break your OVMS in the
middle of a config session, you will need some other way to login to the SEVCON and switch it
back to operational!
Reminder: you need to enable CAN write access (

Example session:
1. Set speed limit to 90 kph, keep default warning @89 kph:
CFG SPEED 90
2. Set max torque level to 110% = 60.5 Nm, keep max power levels at default:
CFG POWER 110 100
3. Set max recuperation to 25% on neutral and 40% on braking:
CFG RECUP 25 40
4. Set torque @ 66 kph to 25% in neutral and braking mode:
CFG TSMAP NB 100 80 50 25
5. Set start ramp to 45 per mille and acceleration ramp to max speed, keep defaults for rest:
CFG RAMPS 45 100
6. Set ramp smoothing to minimum:
CFG SMOOTH 0
Example #2: Twizy 45 emulator
1. Set speed limit to 45 kph:
CFG SPEED 45
2. Set all power levels to 59% = 32.5 Nm / 7.65 kW:
CFG POWER 59
