So, by adding several meters of high pressure fuel hoses with about 20 connections, 4 pairs of wires, 4 connectors, and 4 injectors, we end up with fuel being squirted just to hang around 3 out of 4 times waiting for the valve to open, kinda like old times. This is better than a carburetor how? OK, sure the answer is it's all digital and can be more closely regulated. Fair enough. So let me rephrase that -- this system is better than just having one single injector, upstream, exactly how? |
