looks like someone has tried to tune your 3i using rs turbo injection setup. can't think why though maybe to make it look like an rs turbo?
looks like ke-jetronic but obviously you haven't got the turbo. it's definitely not the correct injection setup for your car. especially as you have the air intake running over the engine ( it's like this on rs turbo's but the air is compressed ) if i were you i'd get hold of another 3i ( probably get a crap one for £100 ) and swap everything back to how it should be, including inlet manifold, alternator, and all wiring.
