406 engine Bosch or siemens

I have the rapier 90 hdi how can i tell if the engine is bosch or siemens so i can get a tuning chip

The engine is a PSA

The ECU will be a Bosch or Siemens, and you can either do a search to find out which, or open the bonnet and have a look what it says on it

if you look on the rail on the engine there should be a sticker telling you which it is i think the early d9 was bosch and the later ones are simens
