Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 Some info needed please.Ignition.I know the Lupo engine uses a wasted spark set up, but is this firing all four plugs together, or does it fire two plugs, then two plugs?Whats the firing order?Fueling.The 1.4 16v engine.Is it Multi Point injection.What would happen if injectors 1+2 and 3+4 fired together?

Mr P Posted December 14, 2006 Report Share Posted December 14, 2006 (edited) Searching around the firing sequence seems to be 1,3,4,2 which is the way most vw engines are set up.if the 1.4 16v engine is out of a polo it is most likely to be mpi (had a quick check of my nan's t reg one!) wouldnt like to say what would happen if 1+2, 3+4 were fired together hope this helps ya tigz.

Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 Thanks Mr P.Thats what I suspected, my ECU only has two outputs for the injectors.I would suspect that as INJ1 cable attaches to Injector 1 & 2, and INJ2 cable attaches to Injector 3 & 4, if plug 1 & 3 fire together, and 2 & 4 fire together the ECU wiring makes sense.If this isn't the case I am totally confused.

Mr P Posted December 14, 2006 Report Share Posted December 14, 2006 thats ok tigz i know how confusing engine electrics can be but by the sounds of it you've got it sussed.hows the project coming along then? Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 okSpoke to a auto electriction who works for us.He says that on the last VW he worked on, 1&4 and 2&3 fired together.So it would be fine to fire fuel into 1&2 and 3&4 together, as ingition is the opposite stroke to compression.Panic over style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...
Mr P Posted December 14, 2006 Report Share Posted December 14, 2006 glad you have solved the issues. i did go through all of this a few months back in college for my apprenticeship though cant remember much of that now style="vertical-align:middle" emoid=":blush:" border="0" alt="blush.gif" /> anymore help required gimme a shout i have dug out the explaination sheets on these matters from college and i'll see if i can help ya style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 OK, I think I have it sussed.There is a permanent live feed that goes to each injector.The two cables from the ECU controls the earth for this circuit.We've just been through the ELSA current flow diagrams, and it looks as though keeping the stock ECU and cabling in place, would be much easier than trying to get everything else to work on the car without it.He is going through both the 1.0 and 1.4 diagram to find how to stick with the loom and ECU from the 1.0, without having to mess around swapping plugs around in the engine bay.I looks like the plugs that a different will not be needed by the unused ECU.This still may change though, Id still like to rip out all the engine loom, and make it as simple as possible.Theres no reason why a 12v supply to a basic thermostat, cant operate the fan without this going through the VW ECU!The plan is, get the engine to run, then decide how to go about it.Who needs planning, eh? lolBut to the nameless guy who reads this, when you work yours out, please let me know lolThats all for now style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> Quote Link to comment Share on other sites More sharing options...
Jez Posted December 14, 2006 Report Share Posted December 14, 2006 Hey dudePersonally, ive just started looking at my loomAnd converting to 'squirti would go with making a complete new loomthen, you got summat to go back on if it goes completely pear shaped!on the polo, there are 7 wires that go from the Ecu to the interior of the carsome you wont need, and some megasquirt will generate (tacho feed, and maybe the gearbox feed, not sure if that goes throguh the ECU) Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 (edited) Thats what I like to hear!Are you making a diagram? style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" />Gearbox feed?

Jez Posted December 14, 2006 Report Share Posted December 14, 2006 Hai can do mate, i need to get all the gear ordered firstwant to jsut try and get the standard setup running on the squirt first, so i know that theres nowt wrong with the engineYou have access to elsa yea?Dont suppose you can get a hold of any of the wiring diagrams for the polo 16v ecu?

Jez Posted December 14, 2006 Report Share Posted December 14, 2006 ah right 1998 Engine code AFHfor mine, i think im going to buy a plug on loom, that comes with 10' of leads on the end, so just need to chop it at the right lengths and get the correct connectors from a scrappy and then solder them on Quote Link to comment Share on other sites More sharing options...
Tigz™ Posted December 14, 2006 Author Report Share Posted December 14, 2006 Sent it to your hotmail addy. style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />Id like to hide as much as the loom as possible, but keep the engine wiring visible.In other wards, anything that doesn't make the engine work hidden if that makes sense?

Teflon Posted December 15, 2006 Report Share Posted December 15, 2006 (edited) the firing order is 1, 3, 4, 2but the wasted spark system allways fires to spark plugs at once 1 + 4, 2 +3, the 'wasted' spark occurs on the exhaust stroke and therefore has no affect on the engine.the lupo actually uses a batch fired injection set-up where all 4 injectors are fired off every revolution, this has the advantage of only using smaller injectors with a lower flow rating, on modern cat equipped enigines it doesn't actually make much difference what type of firing sequence you use for the injection, the only general exception to this is in supercharged engines. however rover use the 1 + 2, 3 +4, semi sequencial injection on the k-series engines to quite good effect, the only thing seen on a lot of 'hot' engines is fully sequential injection where only 1 injector fires at a time, hence 1 single injector only fires once every two revolutions.which ecu are you using?? emerald m3dk??
