Ls2 Coil On Plug Mod

[XKLABA]

When talking an engine like yours the term "mob i might try" should never be spoken

Go to someone that knows what he is doing and has a good reputation for this type of work

if I was you I would contact DVSJez and see if he can run it up and tell you what is going wrong

I have his number and to be honest I am farking sick of this shit.

If they tune rich all the time it will be the same again if I give it back to them

I will call him tomorrow

It is quite possible they haven't set the dead times for the ID1300s correctly

But then there is a heap of things that could not be set exactly correct that need to be which is why you need to take it to someone that knows what they are doing and not just the local mechanic

I do not understand, these blokes have been doing this for a long time and have people out there that swear by there work. You would think this would be easy for them to do right in the first place

I will not bore you blokes anymore and thanks for your suggestions

Im gonna install Haltech soon. does anyone have the settings for these coils

[Looney_Head]

what springs are people using when doing the CoP mod with the LS2 coils?

[Scott Black]

I'm not using springs the contact in the coil is directly on the plug, also dwell time is 5ms

[etang789]

Where do you guys buy your AC Delco D585? Seems like this place has a pretty good deal, http://www.amazon.com/ACDelco-D585-Original-Equipment-Ignition/dp/B000BYD3Y0

drop it back a bit 5ms at 13-14v is asking for trouble

[John.O]

I got mine running at 4ms no problems at all. this is the bracket i'm running at the moment.

[XKLABA]

That's a neat bracket, if you don't mnd me asking, where did you get it from ?

Does this print screen of LS2 Spark Dwell Settings look correct?

[burn4005]

Yea thats definitely on the safe side

here is the OEM GM dwell map for a Yukon truck:

Hi Guys,

Looking at doing this conversion on my SR.. I have found plenty of wiring diagrams so Im pretty sure I can sort it out. BUT if there is a plug and play harness already made by someone I'd be pretty keen to get one.

Also just let me double check, the coils I should be looking to get are D514A? I can get 4 acdelco ones on a bracket etc from ebay for around the $160 mark including plug cables delivered to AUS

As for dwell it seems I should be chasing around the 4ms mark at idle to 3ms top end?

I am running nistune and e85

[MrStabby]

To summarise the way I understand it;

- D514A are powerful and safe, D585s are powerful (guessing probably more than D514A) but can fire early if you run too much dwell, that is, over 4 ms. Firing early "can lead to major engine damage".

- Genuine coils (AC Delco or Delphi) are more powerful than generics.

I'd guess you'd want maximum dwell at maximum torque, because that's when its going to be hardest to ignite the mixture.

Has anyone on here swapped to the LS2 coils while using a Power FC?

I'm considering the swap and given the difficulty with changing the Power FC dwell settings, am wondering if the D514A coils will work fine on the stock Power FC dwell settings?
