ANTOINE Posted January 12, 2013 Author Share Posted January 12, 2013 just to help me for finish the wiring loom less 5 wires, 2 +12,1 +12 for fuel pump,1+ for +12 after contact, and 1 - for mass i think i will try to do the triggle while on an another pulley, and i will change the joint crankshaft with, Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted January 12, 2013 Share Posted January 12, 2013 The general rule with earthing things is: - If it's a sensor/small signal, the earth goes back to where it is being measured to avoid interference / earth difference - If it's high-current / power, earth it to a good solid earth The lambda sensor shows this very well: The signal part gets earthed to the ECU so the ECU has a nice signal relative to its own ground, the heater part is using some current so it gets a good earth for the power to run through. The ground from the EDIS (and from the Megasquirt) is the return path for large currents (coil current or injector current) so they need to go through a good cable to a good ground.

Mr Noisy Posted January 12, 2013 Share Posted January 12, 2013 Fridge, I'm with you all the way on that, but as it happens the Wideband instructions told me to keep all wires together, so I did Had it not been for that, I would have earthed the lambda heater away from the ECU! It does seem to work ok though tbh! Cheers Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 15, 2013 Author Share Posted February 15, 2013 Hi all, a peace of advice, i will put my MS this we, i will put a thor butterfly but on this modele there is not nut for idle and i would like to know if only the pwm can make me a good idle ?? thanks Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 16, 2013 Author Share Posted February 16, 2013 Hi, We finish to fit everything. Now, when we start the computer, we are not sure to have started the software correctly. We did not have exactly the main question "Do you wish to burn values to controller ?" When we tried to start the engine, it seems that it has too much timing spark. When we released the starter, the engine went unclockwise.... but we are sure about the fifth tooth and the TDC mark. Can you help us ? Thanks Quote Link to comment Share on other sites More sharing options...
Mr Noisy Posted February 17, 2013 Share Posted February 17, 2013 What timing is your laptop saying? Rember with this system using timing gun/strobe light the indicated figure is double actual timing because we are using wasted (double) spark system...

ANTOINE Posted February 17, 2013 Author Share Posted February 17, 2013 i don't know how i can say it, when I see the screen on the PC, many tachometer is with a value (temp) i am sure (in theorie) the treegle wheel is good Sam , where i can see the laptop , and what it must be marked ?? this is a Nigel map, i think he know what he do, but me no, and i have read more and more explication, but i think ( hope) i have nothing forget .........

ANTOINE Posted February 17, 2013 Author Share Posted February 17, 2013 when I try to charge my programme, I have this, this is good ?, when I finish and I try to start, the engine bloc, i think too advance on spark .... on this picture i see Edis, this normal ? not twin edis ??? please helpppppppppppp, i want start without broken my engine ...........arggggggggggggh Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 18, 2013 Share Posted February 18, 2013 Your settings are correct, remember that a small difference with the trigger wheel & VR sensor will make a BIG difference in timing angle, so you must make the timing correct using a timing light and adjust the "trim" angle in software. I put everything to 10deg in the ignition table (remember to save your real .msq before you do this!) then use a timing light to check & adjust the trim angle in spark settings until the light shows 10deg, then you know everything is true. For 1st start, I would try to use very "soft" timing, even as far as 0deg, until you can get the engine running & check with the timing light. Trim angle, it affects the ignition map value only, NOT the fixed angle: Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 thanks very much, I am in my garage, and some pics i think i am good can you explain me how to change this parametre, for 10 deg please Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 18, 2013 Share Posted February 18, 2013 Set the whole spark table to 10 deg. Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 to change the advance, I must : 1 move the triggle wheel ? or 2 move the vr sensor ? or 3 change the parametre here ? Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 Set the whole spark table to 10 deg. yes but i think it is at 10 deg alredy, no, look my last picture , if this is the good table i read -10 and not 10 Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted February 18, 2013 Share Posted February 18, 2013 No, not there, the spark table 1 found under the 'Spark' menu. Quote Link to comment Share on other sites More sharing options...

ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 ok what i must change ? please sorry I am not good with this just for the info, i have hc piston and crower camshaft Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 18, 2013 Share Posted February 18, 2013 Yes. The "trim angle" is added to the table, this is how you can make small adjustments to the timing because the trigger wheel + VR can never be exactly right. MS calculates: (table value) + (trim angle) = (angle sent to EDIS) To get the timing correct, set all the "Ignition advance table" to 10, then use the timing light to see the timing. It will be different than expected (unless you are VERY lucky), so you must change "trim angle" until the timing light shows 10deg (so table value = real life).

FridgeFreezer Posted February 18, 2013 Share Posted February 18, 2013 Antoine - when we say "table" we mean the "Ignition advance table": Make all the values in the table "10", then use this menu to make the timing correct: Quote Link to comment Share on other sites More sharing options...
ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 to good understand and not craked the engine here i put 10 near the arrow ? and i change like you -10 and 8 , in the circle ? and here i change only in the red colour, or all the table ??

ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 i begin to understand, but if you can tell me a response for my precedent post i have forgotten i have a duplex timing chain to, and i think my problem can be came of this ............ tommorown i try to found a strombo light ........ i will start one day, thanks again to help me Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted February 18, 2013 Share Posted February 18, 2013 Do this: Then do this: So that your timing light shows 10deg advance (BTDC), so then you know that the number in "Ignition Advance Table" will be the real timing value you see on the engine.

ANTOINE Posted February 18, 2013 Author Share Posted February 18, 2013 ok, thank you very much i will try when i will found a stromb light, tommorown i try to found this, i think i have a problem because i have a duplex timing chain, ??? no ?? after, if i start what i must do ?? change the table ?? how ?? thanks i begin to understand better the MS(small better only) we don't speak again ve table and afr table now, mouarfffffffffffffffff first time, started thanks again to help me Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted February 19, 2013 Share Posted February 19, 2013 Sorry, been away ...Donnington Show also managed to pick up a nice few new parts for the 90 ....and a right royal stinker of a cold - again !! Yuck Will watch this thread and will help sort when you report back Nige Quote Link to comment Share on other sites More sharing options...
