Who douse it? And i assume it will have a new chip on it?
Or is it better to go for 5th injector?

on a mfi s2 the fuel ecu is not mappable, it can have the rev limit raised or removed, the ignition ecu can be chipped to raise the boost limit but not mapped. to raise the fuel pressure on a mfi s2 you need to have the fuel pressure acutator on the fuel metering unit adjusted, when u have reached its limits of fueling which can vary from car to car u then need to go for a 5th injector or efi

So you can map a S1 Fuel ecu?

• Fifth Injector

To achieve over 200bhp the RS Turbo engine requires a higher fuel input. There are two options for this: modified Bosch KE-Jetronic ECU or fifth injector. A fifth injector comes in at higher boost and revs and lets the fuel system supply more petrol to the engine. Make sure the fuel filter is in a good state of repair as an old or blocked filter can restrict the fuel flow to the injector system.

Partially as-above, you don't remap the fuel computer but the spark computer CAN be fully remapped. I believe Ahmed Bayjoo is the only person who can do this.
