I bought some brand new ls2/truck coils but im having trouble finding a wiring diagram. It would be extremely helpful if someone could point me in the right direction.

Thanks.

 

OK. I got the wiring diagram but now im having seconds thoughts.

Will my motor be safe running waste spark. Waste spark is the only option i have right?(as far as using the ls2 with e6x goes)

 

Can you post up the diagram you have? I've been looking for one as well. Thanks!

 

Here ya go.

 

can you use the 2 trailing ignitors with those ls2 coils to make it not wasted spark?

 

I am going to take a stab at answering your question..

I am making a guesstimation. The answer is no. I say this because the ls2 coils already have built in ignitors.


I think ls2/truck coils and e6x just dont go together... I might have to scrap the ls2/truck coils and sell them. Sucks because i bought 4 new acdelco.

 

I remember not using all the ignition out´s. I think I have either the leading or trailing splitted from one output, is that wrong?

 

That's correct. Both leading run off of IGN 1. The trailing run of 2 and 3. Ignition type needs to be wastespark (versus distributor for stock ignition).

 

I'm getting ready to dive into some LS coils. Here's a diagram I made, anyone know if this is correct or what I need to change?...

 

waste spark is an alternating configuring wired in series.

junito's diagram is direct fire, not waste spark and RMS' diagram wired in paralell will only fire one coil because using a single trigger circuit to fire the ignitors will travel the path of least resistance and only trigger one coil per firing sequence.

 

ie i believe if your particular haltech has a waste spark function it operates all coils in that format setting the triggers differently, for trailing it isn't safe to run in a waste spark as the trailing plug is exposed to the intake cycle during the alternating rotor firing sequence.

most more current haltechs use circuit 1+2 to fire leadings and 3+4 to fire trailings. i would just use junito's diagram and run them all in direct fire format. waste spark is more economical for the factory but less safe for high performance engines/setups.

at least those have been my observations but keep in mind i haven't dicked with an E6x unit yet.

 

On the E6X, wastespark would be wired like this:

IGN 1 Pin 36 - L1 and L2
IGN 2 Pin 35 - T1
IGN 3 Pin 34 - T2

The E6X will not do direct-fire as it only has 3 ignition channels.

 

haven't had any issue with the leadings wired in parallel only hitting on one coil? wonder if it would work wiring them in series with the built in ignitors.

even so, junito's diagram is incorrect then for his coil wiring with the 6x then and i wouldn't use RMS' either since running the trailings in waste spark also is almost guaranteed to turn one of these engines into a brick.

edit: or rather his diagram runs a waste spark for each rotor... ie 0 split and rear rotor is running off trailing timing also with 0 split. no bueno.

 

Ok, I didn't expect my wiring guess to be right.






Like this?

 

Yes. Gang both grounds on each coil together in parallel and ground them to a rotor housing or the battery negative terminal, which ever is more convenient.

 

No. Each coil has it's own power, signal, and ground. How would it not fire?

 

if you try it on coils without ignitors you will see what i mean. but being that they have built in ignitors, was curious if it was still an issue(resistance to trigger the ignitors being the issue).

 

I understand what you're saying but, in the context of this conversation, it's a non-issue.

 

So this wastespark setup with e6x is not a full wastespark. it will run the 4 coils like the fatory ignition system? This system duplicated the factory 1? SO would this ls2 coil setup be overly superior to factory fc?

 

Wait a minute, you say that the LS coils should be wired with a splitted IGN wire to the leading coils, which I have. However, my haltech E6X have no waste spark option, so I am currently running this setup as direct fire.

I was actually checking my timing todag which have been fine before, but now the timing mark is jumping around a bit and I´ve even had it firing att 180 degrees off at some point. Sometimes it lines up good and sometime it just dissapear. I check the timing at T1 but the L1 seems to be more accurate.

I also have a problem with the trailing plugs fouling on me.

 

I was having the same problem as you until I used the hitman stab method. When I built the motor I went by the fsm Cas stab and everything was 90 deg off. I stabbed the CAS with the home triggers facing the bolt holes 64 deg angle 3 tooth offset and it runs perfect now. I still cannot get the trail 2 to fire off of ignition 3 though
