A drop in voltage would probably affect the opening ramp, but I can't imagine it affecting the pulsewidth of the signal. The ramp should be a fairly small fraction of the total pulse width. Oh, but the fraction would be greater at idle. Hmmm... Maybe.

Hey, that Tempo alternator setup described here
https://www.ford-trucks.com/forums/s...d.php?t=186398
was pretty cool. When it comes time to replace mine, I could see doing that.

 

That tempo alternator is pretty cool. I'll probably go up to the junkyard and get one monday. How is the existing voltage regulator wired, so I can bypass it?

 

Ok, got it figured out. It's been quite a while, so I figure it's time for an update. I got the electrical figured out. I changed out the voltage regulator to the electrical kind. I got a new (napa) alternator. I wired up the electrical for the fuel injection to a switch in the cab, that comes directly from the battery. I found out that the source I was using was the one that powers the coil, past the ballast resistor.

I had it running fairly well, then it went to crap. After sitting on my hands for a few weeks trying to figure it out, I noticed the fuel filter was plugged. Changed that out today with one of those clear Fram (yeah I know) inline units, made all the difference in the world. I then proceeded to tune it at part throttle, then at full throttle. I would set the laptop to datalog, then I'd go drive it. Come back, tweak the fuel map as necessary, then repeat. Now I'm all done.

With the new exhaust system, and fully tweaked fuel injection, it sounds, feels and pulls like a turbine at full throttle. The only problem now, is that I've become addicted to it. I just keep doing it over and over again, "Like a retarded robot," to quote Ratsmoker.

Thanks to all who helped!

 

Congratulations!
You did it!

 

Well Kurt....Ya did it bud!! Gald to hear it...it was a long process..But now your a Guru at it!! So we'll be looking for the "smokey Burnout video" Kurt style! LOL..

Congrats...Russ

 

I'm workin on that video. The only problem is, I need a place to host it. I could do it myself, but I'd rather have someone with a website up do it.

 

Well Kurt ya might ask Sean, or Brian? I think they do...but Im not sure..Maybe Greg could do it? he's into those hotrod Computers and stuff...

Shoot I just do good to type on one? and that aint worth a crap half the time!LOL!

Russ

 

If it is not too big I will host it for a little while.

 

Thats sounds cool Randy..Thanks for stepping up to the plate for another Burnout!

Bah. The pickup in the gas tank is getting plugged. It turns out having a return line is stirring up the crap in the tank. I can use compressed air to unclog it, but I'm sure it will plug up again. Any ideas?

I was thinking of sticking some rubber fuel line on the pickup in the tank, and drilling a series of small holes in it and plugging the end, to make it so one small piece of crud wont plug it.

 

Kurt can ya put one of those inline glass and metal fuel filters in there leaving one end open..and when it cloggs just put a new screen in it until all the crap is out of the tank ? it may take ahwile..I dont see why it wouldnt work?

 

Do you have a in tank fuel pump? They have large nylon filter "socks" (2"x4") that go on the end of the pump. If not maybe you could fit one to your fuel pickup in the tank. almost all fuel injected cars use one of these "socks". I don't know the real name for them, pre-filter, in tank filter or something. They don't get plugged and screen small enough particles to protect the pump. After the pump you use a standard F.I. filter.

 

Randy..I just added some new Polk Audio Speakers making a total of 4...and it made a differance in the sound of your truck...And your wifes laugh still cracks me up!! Russ

 

It's an external fuel pump that I mounted to the frame directly below the tank. I used the existing fuel line and it's pickup in the tank. Didn't even look at it. I'll probably get around to looking at it tomorrow. Like I said, I have one of those clear fram inline filters right before the pump. I just need to screen out stuff large enough to plug the inlet on the line!

 

That is what the "sock" filter is for: to keep crap out of the line and/or pump.
