Couple of 1.9 questions

[Whizzler46]

I have a 1985 van with a 1.9DH code engine with the Digijet injection system.

Firstly does this run on unleaded or should i be using a lead additive? (never crossed my mind until someone asked me yesterday)

Also is this systems ECU mappable? (more for restoring any lost ponies and aiding fuel economy than power increases)

Thanks

unleaded, time as per Bentley which has the info for the fi 1.9 wbx , ecu is not mappable afaik
