fd3s help...... no crank signal. FFE - hall

Recommended Posts

Do you get a spark if you use the ignition test function?  Trigger 2 sync mode should be set to none but I dont think that would stop it sparking.   Are you getting RPM displayed in the software when cranking?

This indicates you have two seperate problems.  Test mode will work regardless of trigger signal.  If you get no spark in test mode then coils must have either no power or a wiring problem.  What specific AEM coils are you using?

Your trigger settings look ok (except for T2 sync mode mentioned earlier) so it seems you may have a wiring issue with the trigger also.

The coils are getting power as I have tested for that. All the earth check out fine as does the signal wires. Aem smart coils. Should I have it set to falling or rising.

 

I've turned trig2 mode off now.

Now I cant say for sure on the rotary trigger modes, but with a standard piston engine, if the trigger 2 is config'd to something other than none, there will be no spark. 

Ran into this problem on one of my own cars, was running 60-2 crank with multipoint and wastespark.  Up graded ecu and trig 2 got mistakenly set to cam pulse and had me chasing my tail for a few hours.

Trig1 isn't showing any signal, it's just sitting at 10V.

Was the engine cranking while you pressed capture?

I pressed capture then cranked??

 

When I'm cranking I get trig1 signal goes from no to yes though??

Is the sensor too close?? When I received it, there was barely a gap. I would go as to say, touching. I have taken 1mm off. Maybe not enough??

Is it maybe because I have wired it with 12v?? Surely that should read 12 in stead of the 10v the scope says??

And the ecu is looking for a different voltage??

Ok so you dont have a trigger 2 sensor by the looks.  Set trigger 2 sync mode to none then tell us if RPM is displayed correctly..  Your trigger 1 looks ok.

What a complete dumb ass. Previously. I wasn't cranking it long enough for it to register an rpm Signal. 

On that scope log retry I kept it turning over longer to log. Which it did, and will of also given that rpm result , but I wasn't looking for that at the time.

Bangs head against wall several times.....

Thanks for all the help people. 

 

So what timing settings etc do I need for the direct fire setup.
