Almost done... only thing left is to tighten the manifold/headers down, do the plumbing, and the wiring. Sorry pictures are big, I tried to use the width= using straight html code but it didn't seem to take.

sounds like your idle woes are IAC related. |

I need to download that datalogging software. I just rolled my own in XL, but it doesn't look that nice. I turn off my O2 sensor and tune everything first by just looking at the O2 readings when driving at different points in the VE map, or by datalogging. I did my whole 2000+ mile trip last week with no O2 feedback and got 24-25mpg @70mph. Still tweaking a little, but mostly there. I have no fast idle provision at this point, and it idles fine after I rev it softly for 10-20 sec or so. Lou |

I've put about, oh, 250 miles or so on the setup so far. All I did tuning wise was set req_fuel , didn't work much on anything else. Need to fuss iwth the Accelerator encrichment and cold start params, but the driveability is good, excellent torque. |

Congrats, Pierre! You have some work to do with tuning, but it will pay off. Lou |

Latest updates to this mpfi business - megasquirt is now where the glove compartment was - I got tired of it sitting on the floorboard so I finally found a home for it in the dash. Pretty soon I will be getting rid of the relay board (I really don't like the type of screw connectors on it) and wiring everything directly to the board I mounted the computer on under the dash. Also redid intake plumbing - http://home.inreach.com/~pierre/airclea ... erside.JPG http://home.inreach.com/~pierre/airclea ... rfront.JPG I can now feel confident driving the car with one foot. Once I re-routed the fuel return from the pump input directly into the tank, hot idle is plenty stable now. Every now and then I plug the computer in and tweak the tuning, still needs some work to be 100% solid but tis a never ending adventure of fun

Pierre, the "width=" doesn't work anymore (don't know why) but a recent software update resizes your pictures automatically and allows you to click on the picture to load the larger image.

Nicely done... way to persevere on a project and see it through. Did you document how you got your MP injectors/fuel rail hardware set up? Did you have the fuel rail made or did you fab it? I have been running MS for 2 years on a '77 Ramcharger and love it. MS is the way to go. My Duster will have MS injection and spark control. Good Job!! |

The fuel rail and manifold came as you see it in the pictures from clifford direct. They apparently at one time were going to sell mpfi setups and they made a limited run of mpfi manifolds and rails. Those plans fell through - he gave me the manifold with bungs already drilled for same price as a regular one, and fuel rail for an extra $20. Only thing I "manufactured" were those hold downs and adapter plate for throttle body. Those aren't MP injectors, they are 22lb ford/denso injectors from www.fiveomotorsport.com Other than what's in this thread I don't have anything documented.... feel free to ask me anything here. |

Wow... thanks for the compliments, I thought my installation was craptacular personally.... The bundymobile is downed for a while, hole #4 had 60 psi compression, 100 less than the rest, due to jacked up exhaust valve/seat. Getting complete rebuild done, should have the engine back within 2 weeks. Should make the EFI easier to tune.... I may do little stuff in the meantime while engine is out, cleaning up engine bay, wiring, etc. We shall see. Eager to get the new mill back in! |
