The Buschur Racing Coil on Plug Ignition System and HKS twin power DLI II basically the same thing?

 

I have heard that the HKS DLI is basically more bang for your buck, pretty sure this is what buschur is running instead of the Coil over plug setup. I was kind of wondring the same deal becuase right now my 03 ignition seems to be crapping out at about 23psi with a 3076, never seemed to have a problem on the stock turbo.

They both amplify basically for a better signal, the COP though uses one coil per plug where the HSK DLI doesn't. It maintains the wasted spark.

 

whats the difference with wasted spark?

 

Wasted spark basically fires two cylinders at the same time. One in the exhaust and one in the firing cycle. This can cause heat and in high rpm cause the ign charge to get weak.

Coil on plug fires only one plug at a time gives the coils more time to recharge and produces less stress and or heat for a better charge.

Hope this helps.

 

Think of the HKS system as using a really nice Marantz amp and bottom line speakers from Costco and a true coil on plug system steps up and uses the right components. From what I understand, the HKS system just amplifies the signal, but you still use wasted spark and only have 2 coils versus 4.

The HKS is cheaper, but, as they say, you can either do it right or do it twice.

 

Actually anything you would put on the Evo will be a wasted spark setup with the stock ECU, even if its coil on plug.. The stock ECU only has 2 triggers (I think you can run a true 4 channel ignition with the AEM EMS)


Regardless of which system you choose, you want something that provides enough voltage to quickly recharge the coils, and something thats CDI since a CDI system will improve idle quality and reduce low RPM and Idle misfire. the Higher voltage improves the recycle time of the coils and therefore you will get a better spark at higher RPM, and the higher output will allow it to jump a larger Gap..

These systems are expensive, and shouldn't be your first mods, but some cars that have poor idle, and misfire at high RPM are good candidates for it..

the HKS DLI2 appears to be both a CDI And transistor discharge..

Anything is an improvement over the stock ignition, but you have to weigh the value.. Since it will only recover power that is lost due to inefficient ignition, the amount of power you gain is very dependent on everything else you have going on.

 

I was only referring in general, sorry next time I will be sure to categorize the information so it is to everyone’s likings. I was just defining in general. I don't have allot of information on the coil over plug ignition that Buschur built to run on the AEM since the AEM uses a collective amount of teeth to figure out the trigger so things know when to fire on either setup. Whether the coil over plug that Buschur sells does this in a Wasted or coil over plug form I don't know but hopefully we will all find out so we truly know which one is more worth the money. Buschur does seem to like the HKS unit though.

 

I haven't taken Electricity and Magnetism in awhile, and I may be mistaken, but I thought that 1) "Wasted Spark" ignition systems were invented to force the spark to jump TWO air gaps, thereby increasing the discharge voltage and 2) the strength of the discharge is proportional to the energy applied and inversely proportional to the time it takes for the field in the coil to decay- NOT the time it takes to "charge" it.

Can someone with some more technical and/or practical knowledge speak up? I'm not sure I'm remembering this correctly.

 

Yep.. what you said is correct.. however the term wasted spark is commonly referring to the spark being wasted on the exhaust stroke (AFAIK).. I should have used the term Recycle and not recharge in both instances.

 

Thank you! I didn't expect to get my question answered by the expert. As always, your posts are informative and to the point. Thank you for all that you contribute to this board.
