Ecu Upgrade - Help Please!

[babaroga]

Guys

How can I upgrade ECU sw for 59 plate rav 4, 150 bhp version diesel, with the latest version and can I use Techstream to upgrade it? (if newer version is out).

Does Toyota provide ECU files on their wesbite ?

Thanks

As far as I am aware the updating of the software can only be carried out by a Toyota dealer for two reasons:

1. The EU now requires manufacturers to store/report the updating of engine control units to prove that the car still meets the relevant emissions regulations they where originally designed for.

2 The update requires the use of a VIM ( vehicle interface module ) this sits between to Techstream PC and the car and the update is transferred from the PC into the VIM then onto the car. At our dealer we have both full Techstream PC's with VIM and Smaller Techstream lights that don't have a VIM these can do all the operations of the Full machines but cannot update ECU software.

Many thanks for the info.

Do you know by any chance how much is upgrade at the Toyota Dealers these days?
