    Okay, I have been looking at FI lately and notice that alot of them or most of them are computer operated... is there a fuel injection set-up for custom built engines with-out a computer. The reason being I have bad luck with electronics in the truck. Another thing that worries me is, in deep mud, or water crossings couldn't the computer get wet? Or am I missing something. I don't no where your suposed to mount them or anything so If anyone can help me out it would be fantastic /forums/images/graemlins/woot.gif

    Fuel injection without the computer is called a carburator. /forums/images/graemlins/rotfl.gif

    No but really the most important and great thing about EFI is the sensors and the computer, and the adjustments that can be made as a result. This is what makes EFI so great--that it can constantly change parameters due to engine load, temperature, etc.

    The comptuer is inside and at dash level. If it gets wet, you're already screwed anyway so it doesn't much matter.

    /forums/images/graemlins/doah.gif I feel like a idiot now. Well at least now I know that the computer will be safe. For whom who has them... how are they for user friendly? Are they easy to adjust? Thanks /forums/images/graemlins/thumb.gif

    I'll have to say this, do a search for terms like ALDL and WinALDL, you'll pop up some examples how user friendly they are.

    If you're cheap, a paperclip can give you the trouble codes. You can dive in deeper with a laptop and a cable and look at what the computer is doing, and go even deeper by 'reprogramming' it. /forums/images/graemlins/waytogo.gif

    1960's GM rochester fuel injection was mechanical. Used a fuel pump driven of motor. Very pricey to 'vette guys. Good luck finding one cheap, plus hard to tune.

    There were many types of mechanical Bosch fuel injection on european cars. Would not transfer easily if at all to a SBC.

    If you can't go EFI, get a q-jet. Patience and help from a few ck5 members, and the thing will run a long time..............at extreme angles /forums/images/graemlins/k5.gif
