-G60 (code PG) engine came equipped with Digifant engine management. This is all electornic and can also be reprogrammed with custom chips which can be even found from Ebay (I dont recommend). But same time this ecu also show some age, with only narrow-band oxygen sensor, distributor etc. Since its all digital, convertion to aftermarket ECU is "relatively easy". I have run G60 with Megasquirt and now later making new build based on MaxxEcu. Here are some notes, I'ven taken.

-~~DISCUSSION~~
+===== Fuel system =====
+Corrado has electronic fuel injection. Depending on year of manufacture there is one or two fuel pumps. My model has one in tank, originally Pierburg unit which broke down and later on has been replaced with Bosch pump. Bosch part number is "F000TE0111", which fits with single pump models. If you are replacing Pierburg pump with Bosch, you need also new fuel gauge sender unit. That Bosch pump should produce 150l/h at 3 bar pressure.
+Pump is controlled by fuel pump relay, which is controlled by ECU. Control wire goes to original ECU, wire color for relay control is red-yellow and conviently there is another red-yellow wire which comes from same fuel pump relay output. Near ECU there is 3-pin connector and 4-pin connector. 3-pin has following wires:
+  - red-white = power from mains
+  - red-yellow = fuel pump relay control
+  - red-yellow = output from fuel pump relay control
+Injectors are Bosch 037906031D, 245cc/3bar (I cannot 100% verify that). High impedance, can be used as is by many engine management systems. Body type is EV1, wiring connector is Jetronic/Junior Power Timer. You can get bigger EV1 body injectors, or look for newer Bosch EV6/EV14 60mm body injectors which should fit also.
+Note that original injector wiring is very likely brittle and should be replaced. Also original fuel rail is plastic, mine seemed fine for 30-year old plastic but you never know. Replaced it just in case and to ethanol-proof fuel system.
