sorry for MIA for quite sometimes, have to settle down on workshop at kuantan, wife deliver 2nd baby and involving in some motorsports event.
now back with additional product: ATF oil, gear oil, engine oil 5W50, 0W50
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...
