Lanos 1.6 (VEMS and turbo on the way)

Ok so i definitely have spark now with the stepper motor, but i can't get the car to start

what's happening now is i crank the car and it feels like it wants to start and then all of a sudden i hear a bang from the exhaust, i'm using the config from a c20xe in the firmware release you gave me rob not the c20let because it runs on high boost, and then i modified the msq to suit my engine, and i'm stuck now on those bangs, here is the msq file

Now your talking!

Are you sure that the ignition is not 180deg out?  What cranking PW and advance are you running.

How are the plugs looking?  Are you rich or lean?

[bob3825]

how can i check if the ignition is 180 deg out?or what are the symptoms?

And these are the settings, i didn't change them much from the c20xe because i didn't want to mess it up as the config i messed up 



give me 5 minutes i'll go check the plugs

[bob3825]

I checked the plugs and they are full of carbon build up so i'm running very very rich

Hi,
Check with a timing light on the crank pulley timing marks.
Or the Ghetto way is to just swap the two trigger wires from VEMs to the coil pack around and see what happens then.
Cheers,
Gavin

I have no timing timing light and i don't think its sold here, i asked lots of people and friends but with no hope, i guess i have to try the ghetto way

[bob3825]

i tried swapping the vr sensor wires but that just resulted in strange rpm readings

[gunni]

No he mean the wires FROM the ecu TO the coil pack.
i.e move the pairs of cylinders that fire.
That way your moving the ignition timing 180Deg.

[bob3825]

oooh sorry i thought he meant the trigger wires, i'll try that and see if it will work

but won't that have the same effect as swapping the values in the ignition outputs from
0---->Stepper A
1---->Stepper B
2---->Stepper A
3---->Stepper B

to
0---->Stepper B
1---->Stepper A
2---->Stepper B
3---->Stepper A

or am i mistaken?because i tried that already

[rob@vems.co.uk]

Changing the order of the outputs is exactly the same as swapping the wires, and loads easier!

You really need a timing light, they must have them in commercial garages over where you are.  The clip onto the battery, and have a 3rd clip that attaches to one of the HT wires.

A nice simple one like this:

Would be perfect.

[bob3825]

Ok i'll go search in this commercial area over here and hope i find one, if not then i'll have to order one and wait for it

[bob3825]

i managed today to dig up the wiki (which i don't know how to use  ) and managed to find the trigger settings for a similar setup as mine and they actually worked, but the car still doesn't want to start, what happens is i crank the car, it responds normally and actually feels that it wants to start and reaches about 650 rpm but then just dies out, so i'm guessing its my afterstart settings or either my VE, spark or both maps are off

just trying to get the car started untill i find a timing light

advice please

Well now you´r getting into the tuning phase it seems.

Do the trick where you set crank threshold rpm to 2000rpm
Then adjust the cranking PW until your engine catches and is able to run.
You can adjust the timing to keep it running. When your able to start it like this
you can lower the crank threshold rpm and tune from their on.

[bob3825]

I guess this is the tuning phase since any plating around with the cranking and afterstart settings changes the way the car tries to start
and by adjusting the timing you mean the spark table or something else?
i'll give that trick a go and see what happens

[gunni]

Crank advance
in the crank, priming & afterstart settings.

Should be 10 to get running and idling.
