Hey guys/gals,

I'm actually not an LS2 owner, but I'm working on a project for another car and thought who else would be better than the LS community to direct my questions at.

First off, I have a set of D585 coils 19005218, is there any place that has full specs on these coils? Besides the heat sink, can anybody tell me what advantage/disadvantage/differences there may be to the 585 over a 581 or 510c?


Second type of question. I need to make some plug wires that securely fit the d585 coil, do you know the best part # for the coil terminal boots to use?


Much appreciative....

Read this article and watch the video. Summit has the coil terminal and boots for the wires.

The D585 coils require you to use a lower spark dwell time than other LS coils. If you dont they will start to overheat, but to protect themselves they will just spark early....which isnt good.

I dont know the point at which that happens, but thats what ive been told.

I've never heard of shorter dwell time on the D585's. You know where any documentation is on this?

I have a set on my TA for over a year and 0 problems with the stock dwell times.

I searched the parking lot at work today until I found an a set on an '02 tahoe. Then I uploaded the stock tune off the truck with HPTuners, and copied and pasted all the info into my personal tune since I have the D585 coils myslelf.

I have heard about the shorter dwell time more than a few times.....

The shorter dwell time is correct. As stated just check the difference in the tune file for a truck with these coils.

I did not know this. I'll check the difference between my 4.8 truck tune ( D585's ) and my 00TA ..

Here is the tune I pulled with D585 coils....Copy and paste anything that different in your tune if using these coils.

No problem, did you see a difference in dwell time settings??

I know mine has been too high for a while now, I like knowing im getting things closer to being correct
