Now I installed the VR circuit,
as I have this on my board,
now I get this while cranking:



I sometimes get this after switching on the MS.
:


Should the CAM in settings set to off or on?

I tried this with these settings:

Ignition output capture: Rising edge
Spark output: going low
Spark hardware in use: LEDs spark

you still have no cam input.


When using the VR circuit, you need to use the cam in on the ms3x board to match the polarity. With the cam still on js10, I don't think you can run the VR input.


regardless of this, youre still not getting a cam signal at all.

botte

OK, so I have to rewire it to your setup or get an MSX board.

regards of VR to opto, without the Ms3x right now, the cam signal should be going into JS10 with a pull-up with a 470ohm resistor to 5v to at least get a signal.

botte

Ok, Makes sense.

So I put a cable from VRIN to JS10 and I put the 470 ohm resistor from JS10 to 5V,
Same as you did in your setup.

Then the signal should be there?

Braineack

no. iac1a to js10.


vrin/opto in is your crank.

botte

Thanks!

Its working,

I can see the cam now on the composite logger:



But I still do not get a spark.

Braineack

that's becuase your crank is outputting a falling edge signal and cam rising edge.

you could try switch your ign settings to the alternative one...i cant remember if that works. but those red lines represent where the MS was expecting a signal.

if that doesnt work, you need to revert back to the opto in for the crank.

botte

Ok,

I went bacvk to the optoin settings.
But I still get these sync errors:

Rising edge:


Falling Edge:

Braineack

yeah you gotta put the crank back on the opto circuit.


so:
tachselect to xg1
TSEL to optoout
top of c30 to 5v
and d1 and d2 are open.

botte

OK,
I did this,
i get this now:

Braineack

set to rising edge?

botte

Yes, rising edge
I just that i have a cable also gong from D1 to U5 (next to the seriel Connection), do I Need to remote this?

Braineack

iTrader: (62)

try falling?

botte

Looks much better:



Edit:

IT IS ALIVE!
Thanks Scott!! You are great!

there you go! wonder what was wrong at first.

botte

I have no idea, but its running, now :-)
