Toyota Yaris conversion

Post by evev » Mon, 16 Oct 2017, 07:24

Hi,

a couple of quick questions for the experts:

- can a late model vehicle be converted like a 2014 Yaris? I thought I read somewhere there were legal [Australian design rules?] issues with late model conversions

- if it is legal to do so, what would members recommend for a conversion for a town run around that is likely only to need a 30 - 50 km range?


Thanks in advance.

One issue with some (many?) late model cars is traction control/ADC and how integrated it is with the engine management computer:
1. you need to keep the traction control/ADC working
2. sometimes the computer which manages the ADC also manages the engine or talks to it in a non-trivial way
3. when you convert the car you remove the engine
4. the traction control/ADC computer no longer works because it thinks the engine is missing.

This affects some older cars, e.g. Smart ForTwo (the common tiny ones)

Thanks, looks like that idea is dead in the water then.

Not necessarily, the ADC / traction control may have a simple connection (e.g. cut the throttle) which would work for an EV too.
