  • The F.A.S.T. ECU in the video uses a property of mechanical physics called PV=NrT. The numbers in the Base Fuel table represent the engines Volumetric Efficiency. With this number the ECU can determine the proper amount of Injector Pulse Width that is needed to achieve the desired A/F ratio.

  • I believe the word is "interpolating" :)

  • @EFIUniversity There is a reason for your username. Good info dude! :)

  • @INSONIASXPOWER IWithout "software" your car would run shit(well sure you can go old fashion with carburators and FPR's) Yu change the hardware to make power , you use software to make sure that you get the most out of the hardware; something that stock ecu's aren't doing(as they're always tuned for something like 91RON and 30c ambient temps)

  • @INSONIASXPOWER Are you kidding me ?

    Ever heard of timing and variable valve control ?

  • @EFIUniversity

    First PV=mRT is the equation of ideal gases and second it has nothing to do with the VE you are reffering.

  • Easy fix scrap it and get a decent car that does not have Vagina-tec.

  • and my scanner tool wont communicate with the ecu.everything works good in the car though.thanks in advance

  • hi evbody! i got a problem with my honda civic 96.the data link connector seems to be dead
