Erm .... It's easy enough with a little knowledge, BUT it's also easy to make a mistake with a little knowledge ...

Fit the uprated fuel pump.
Fit the 560 injectors.
Fit the 7 ecu.
Drive the car

Flashing the ecu with new maps is more involved. Easier to find guides or posts already done than to rewrite....

This should help with the basics http://www.evoowners.co.uk/f33/add-pops-bangs-your-evo-3562.html

you'll have to swap over a few pins first before the 7 ecu will work in the 4

this should help a little with that bit mate.

Evo4/5/6 to Evo7/8 Ecu wiring conversion:
Connect cable 8 to pin 22 (Fuel pump relay swaps with AC control relay) *not req. for Evo7 ecus I checked
Connect cable 22 to pin 8 (AC control relay swaps with Fuel pump relay) *not req. for Evo7 ecus I checked
Disconnect pin 87 AYC/ACD signal
Connect Cable 20 to pin 32 (Rad. fan hi to Condensor fan hi)
Connect Cable 21 to pin 34 (Rad. fan lo to Condensor fan lo)
Connect cable 6 Secondary air system to pin 53
Disconnect pin 91 or rewire for IC sprayer manual operation
Evo 4 only: Disconnect pin 40 and ground cable or connect to pin 92 sensor ground *definitely required
Evo 4 only: Disconnect pin 33 if alternator is not charging battery *not required for any Evo4's I tried
