#96501, "fmu and sfmu"


          

Hi, im about to finish my custom turbo kit and now I need to choose my fuel setup. Im afraid to run the stock injector with 8 psi and a fmu 12:1. I know it will be 100psi+. If I buy #310-315cc... injector and just put maybe a 10 or 8:1 disk it will be better right? For the idle, I think I cannot ajust the idle pressure with fmu ? Should I just wait and buy and sfmu with 315cc instead ? I just want to be safe and I dont think to run higher than 8-9 psi of boost.

thanks

IF you are going to stay at that and want to run safe but rich then you can stick with the 12:1 fmu, but if you want to up the boost later or if you want to run right and not rich all the time then get the sfmu. Others will tell you to consider the Megasquirt. Its up to you, the simplest fuel set up is the fmu, better option is the sfmu, and best is MS.
