FMU question
I'm planning on getting a vortech fmu for my 90 turbo civic si. I have 340cc injectors, an adjustable fuel pressure regulator and boosting 9psi. I'm confused on which one I need 12:1 or 10:1 or 8:1. I have a stock fuel pump. I'm not exactly sure I know what those numbers stand for. Just need a little help from you guys. Thanks for any and all replies.

Re:FMU question
Since you have 340cc injectors.. 4:1 or 6:1 would be OK.
Numbers represent how many PSI does it need to increase fuel pressure regarding to each 1PSI of air pressure. For example with 6:1 ratio: 1PSI boost = (stock fuel pressure)+6PSI (from FMU) 2PSI boost = (stock fuel pressure)+12PSI (from FMU) and so on... Just bear in mind that stock fuel pump is *not* good for higher fuel pressures... |
Re:FMU question
OK.
Read the Engine Management FAQ at the beginning of this forum. If you still want to use an FMU after reading that, well, you're on your own. FMUs are not for "high boost setups". Take the time to do your setup right, and it will provide you with the well earned power. Half ass it, and well, you'll see.. :-\ |

Re:FMU question
If you really did do all of that to your motor.. why the hell are you half assing your Engine Management.
It's ENGINE MANAGEMENT. It controls your engine, you know, the thing you spent all the money on. Wouldn't you want to protect it? Wouldn't you want to get the most out of your money? Please, read the FAQ. Change your EM solution. |
