we've got RPM input. There are some pins on the ECU board that have jumpers on them, ad they were not jumpered right. I moved the jumpers to the right spot, and we got a noisy signal, so I adjusted the crank position hysteresis and noise circuits, and now have a nice, clean signal. the missing tooth is pinging about 3X higher than the rest, and the rest have a nice smooth wave motion to them with engine cranking RPM.

It still wont light, it sputters and burps up the intake manifold, but, won't go. I pulled a plug to check spark, and it blew a TON of fuel out the plug hole, so, I need to make some adjustments to the fuel curves. My widebands are pegged out full rich, <10:1 AFRs, so it needs som trimming, and it will probably light.

 

Done with the truck till spring, if ever again.

Something's wrong with the fuel system, drained the oil and there was 3 1/2 quarts of gas in it. I know for sure that all the misfired have blown an exhaust manifold gasket, and probably a headgasket while trying to sort out the crank position sensor issues, and, with that much gas in the oil, probably spun the bearings in the bottom end too.

I'm just tired of it.

 

Man that sucks, sorry to hear about all the problems. Don't give up on it though, it's too cool of a build to quit on.

As I've come to learn, our favorite projects are the ones that drive us nuts the most.

 

took some screenshots and posted them up on the megasquirt forums. Guys over there are helping me out a lot. I had some things backwards.

Figured out the reason for the flooding. The injectors have to be tied to a SWITCHED 12V source... doesnt show that in the harness diagram, so I had them hard wired. Changed that, and it has stopped flooding as badly.

Have started working on some other lttle projects I was going to do later, just so I feel as though I am still making progress. Got the front winch cable wound on, works good.

 

A beast!!!!!!!!! Love the tires.. but there is simply nothing Audi about it, well, cept the F.I.

 

THE BEAST LIVES!!!! AH HAHAHAHAHAHAHAHAHAHAHAAAAAAA!!!!!!!!!

:twisted:

 

oh, and YES, I heard the PS pump whining in pain. I swapped the lines around on the tie rod cylinder, and limped it out of the garage:

 

Been following this from day one. Love it man great work.

Congrats! Pure awesomeness. I bet anyone on the road near you is going to be sh*tting their pants. Either that, or creaming them!

 

Your rig is pure insanity man! This has got to be one of the best build threads I have ever seen, kudos to you on the crazy amount of custom fab work.

Just crazy.

Good luck with the tune and working all the kinks out!
