I've tried 550cc injectors on RB20det (that means 6 units) with SAFC 1 blue screen, the car can still run, but it's too damn rich on fuel, even if everything is set to -50% and even with fuel regulator installed...
My 4 wheel steering (HICAS) is not functioning due to broken wires in the Boss kit (between the steering wheel and dashboard). I tried to fix it but failed. :sad_smile:
