    You might've wired it incorrectly, call URD and ext#3 to reach Gadget.

    you did disconnect the battery before doing this correct?

    you are sure the green & violet connections are in the right order?

    did you solder the connections or crimp them?

    I didn't disconnect the battery, but after i rememberd, i unplugged all the plugs from the ECU disconnected the battery and then re plugged the plugs in hooke the battery up. Checked the green and purple, they seem to be in right order. I just twisted together the connections until i knew it would work.


    Next Question:

    This is a stupid one, but when i connect the wires of the MAF calibrator do the wires connect the plug end (the part that goes in to the ECU or do they go to the end that goes out into the vehicle?

    Look up Under Dog Racing Development and its called a Mass Air Flow Calibrator.

    Negative! Your not splicing 3 together, you will be replacing some wires with others.

    ok, well i don't know if i've accomplished anything or not, other than, the truck runs. What I tried:
    I connect the MAF wires to the plugs going into ECU, nothing.
    I connect the MAF wires to the wires that would have been leaving the plugs on the ECU, nothing

    What worked (as in the truck runs):
    I spliced the MAF wires into the wires going into the ECU plug and out into the vehicle. Will drive it here in a few minutes and find out if there is any improvement, I did start it and it sounded different.

    you want to peal back some of the rubber coating and wrap the calibrator wire around the ecu wire, then solder them together

    the green & violet connection is the only wire that you have to cut...then you will connect the wire "through" the green and violet wires

    Yup, definitely got it working, felt the difference going home and back to work, I notice it around 2500 rpm, but generally i can feel it through the gears and throughout the rpms. Gas mileage, hard to tell at this point cause the foot was quite heavy with the new power.

    I noticed the power jump around 3k rpm and my mpgs have gone from 16mpg avg to 19mpg avg (daily driving). If you're a manual, hit an onramp in 3rd and keep at it til 60 in 3rd...fun stuff right there

    What intake setup do you have? I have the volant with scoop

    .
    Glad it worked out, the other thing to make absolutely sure of is that you don't have any shorts, I would recommend heat shrink, if you cant find a three way shrink, then what i did was get some wider (flat) shrink, cut a length of it off, then split it open. I then folded my splice so it fit inside the split open shrink and then sealed it. I took as much time doing the heat shrink as i did doing the splices.
