Anyone able to advise.

Cranking engine and this is the trigger scope I have got.

But it seems hit and miss.

Not tried to fire with fuel yet.

Just seems very odd to me but I am very new to this so trying to learn.

Many thanks

Probably need to remove 1 lug from dizzy 

 

maybe signals are back to front as waveform is negative value

Just make sure crank is on trigger 1 and cam/dizzy is on trigger 2

 

sure admin will confirm settings soon

I had planned to take the lug off but was trying it in the duratec vct setting first but  no joy.

Hoping may get a better understanding before I remove it.

Had big back fire once but keep getting trig1 error counts.

Scope just isn't looking like expected so not sure if issue elsewhere

Your trigger scope shows no signal at all, that is just noise you see there.  Did you click the capture button while the engine was cranking?

Morning.

Yes I had press capture. Or do you click whilst its cranking? I clicked before cranking.

That's all I seem to get everytime.

 

If I try with fuel it either coffs and stops or had it back fire once

You have to click it while the engine is cranking and then keep it cranking for a few seconds until the waveform is drawn across the screen.

Ok, trigger 2 voltage is quite low so set trigger 2 arming threshold to 0.2v @ 0rpm and 0.5v @ 1000rpm.  

It would be strongly suggested to remove one tooth from the dizzy for the most robust triggering but it may run with the duratec mode.  You will need to check trigger offset with a timing light.

Will give it all a try.

Struggling with battery power now. Think it may have had enough so will try my spare and order a new one if need be.

I will also pull the dizzy and remove the lug which comes closest to the crank missing tooth.

 

Happy new year
