Thank you Jasu, you are making it easy for me.. Now I don't need to search take a look at the bleu note...
and at the arrow it says it all....Attachment:

And you stopped reading after you find that. "Forgot" all what is there about timing etc... If you use one squirt/720 degree doesn't mean you have sequential injection... |

Now please read the article and try to understand.. And here's another article about the same.. http://www.extraefi.co.uk/sequential_fuel.html Attachment: sequential.jpg You see 1 squirt at 720 degrees here it is timed just before the opening of the valve... All what you mean with timing and alternating is just to try to immitate a sequential injection without being one (so a injection system without cam trigger)... |

SFI: Sequential Fuel Injection One injector per cylinder with a firing circuit for each injector individually. Results in better emissions and more power. |

Beter emmisions yes, cruising a long more fuelefficiency yes, but at wide open throttle theres almost no gain because the injector needs to be open longer then the intake valve is... as Jasu said already.. That's why I'm using 2 injectors at wide open throttle, I hope I can squirt within the opening time of the valve at wide open throttle and because I am squirting LPG it doesn't need to vaporise (as petrol needs to do).... |

And as I said earlier, I'm quite sure we are talking about same, but different words. Because both of us (me and Geo) don't use our "nature language" but english... By the way, I have researched a lot about D-Jetronic, because of non-correct-working of a DS21ie what my friend is restoring. Very nice "computer", without anything but analog electronic! Almost all functions what modern EFI has, with that first generation of D-Jet. Old traditional electronics, only discrete components and all the fun what an electronic engineer like to have... Also, another project, convert MS2 to handle D-Jet at DS, to other daily drive DS with 5-speed hydraulic gearchange (made by Harry Martens, that 5-speed). |

just some thoughts about 1-2-Squirt software..... Attachment: 1-2-squirt homescreen.jpg Ok orange is spark, green is fuel, I can't make it easier for you... Attachment: 1-2-squirt injector setup.jpg Here you need to fill out the time which is needed to open and close the injector in us, again at lower rpm theres lowes voltage so slightly longer opening times of the injectors Attachment: 1-2-squirt airtintaketempcorrection.jpg This is a corection on top of the fueltable in percent a coller engine needs more fuel then a warm engine.. You can correct it + or - 125 %.. Attachment: 1-2-squirt coolanttempcorrection.jpg see above Attachment: fuel table.jpg At last a fuel table. I will start with a 12 by 12 table just like adavance, later on I can always change it to 16by 16 or more... This can be filled out by values from 0 to 255. which means 0.0001 to 0.025500 seconds of squirting petrol... so a factor of 100 (us) will be build in. Maybee lateron I can make this factor adjustable just like the req-fuel in Megasquirt.... Well is is just a start... ok.potential testdrivers can start to read the Megascuirt Manual...

Your a mad bastard Geo! (Aussie compliment)  I guess the real benefit of sequential is for spark rather than fuel. Would you agree? My understanding is that both systems require the same inputs, eg. cam timing etc. Sequential ignition is what I am most interested in. Keep it up! Harley |

Nice, like it a lot! just one question your table goes up to 6000 rpm? is that enough? now you have to program an automatic adjustment using a lambdasensor (just teasing, if you get this, like it is, working the right way it would be great!)greetzzzzzzzzzzzzz |
