    fast logging results ?

    Pinch off the return line and fuel pressure should go over 100psi if not it is a fuel pump problem, If it does than you have a regulator problem. Forget everything else and fix the fuel pressure problem first and than see if you have any other problems.

    fast logging results ?

    Your fuel pressure needs to be at 45psi min. What injector size? and are they ID in the FAST the same ? Sounds like a fuel pump or regulator problem, a vac. leak would not decrease fuel pressure.

    VE table- Max RPM?

    I would not try a full pass, Start off slow and get a feel for the fueling of where it is.

    VE table- Max RPM?

    Norbs is correct you will need to correct for the longer cell width but at low RPMs it wont be as much as at 7000. Data log at lower RPMs and adj than increase in steps. It should be close if you are letting the WB02 adj.

    VE table- Max RPM?

    In Ccom WP go to system configuration, operational parameters, table cell width(RPM) set to 500 that will be at 7500

    Why is it lean on passenger side?

    Spud You said you were still garage tuning so I take it that the A/F difference is at idle and low rpms. If this is so I would load the motor a little against the convertor to see if you A/f starts to stabilize many times you can have a header leak as small as a pin hole up stream of the...

    I need some serious help with this XFI POS box.

    I would not be connecting the battery 12V to the fuse block. The best place for that connection is directly at the battery. Put a test light on that circuit when you are cranking, I would bet that it dims and even might go out. If so that is most likely the source of your problem. Its not the...

    Why can't my XFI box hold a program?

    Some quick info on how the XFI saves changes. When you turn the ignition on you will notice that the green power light on the XFI box comes on. Whenever you make any changes you have to turn the ignition off but make sure that the battery power to the ECU is not lost. You will notice that the...

    XFI Race gas C-16 to E85 results

    Bob I have no experence with the ME-R , If you can target or read your WBO2 to 7.8:1 and get about 32% more fuel in the motor you can do it. We had 83 # inj. re id to 101# @ 65psi. We are now putting in 160# and are going to re dyno with more boost.

    XFI Race gas C-16 to E85 results

    If you do the math 11.5 A/F will be 7.8 A/F, but you don't have to because the XFI will convert it when you change your Fuel Energy Constant.

    XFI Race gas C-16 to E85 results

    I believe the same will hold true with fuel pump output. If you have a fuel pump rated at 1500 HP on gasoline then on E85 it should be good for 1020 HP. 1500 x 0.680 = 1020 or 1500 / 1.47 = 1020 (as Craig stated above) either way will get you in the ball park.

    XFI Race gas C-16 to E85 results

    The difference between gasoline and E85 is 32%. So I would start there. Craig would be the one to field this question since I seem to remember him running Methanol with a classic FAST system. Methanol has a fuel energy constant of .439 and E85 is .680.
