Ls2 Coil On Plug Mod

[omnigear]

thats why i went with the D514A along with that if the 585 gets too hot they go to safe mode. or so I read.

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.

So you're using the D514A with stock Nissan dwell settings?

Also what plugs are you using?

[omnigear]

I have nistune, i dont remember the spark plugs

Last question I promise... Are you using the www.LS2RB.com coil bracket?

If so, did you have any problems fitting the D514A coil? as I believe that bracket is designed to fit the D585 coil

[omnigear]

D514A cant use the LS2RB/ MojoPerformance

gotta make a different one

Thanks mate, I've been in touch with Rick from Mojo Performance and he has informed me that the stock Nissan Dwell setting is around 2.5ms. So I will be fine to run the D585 coil without any risk of premature firing with the standard Power FC settings.

Although you can get a better spark by increasing the dwell slightly, at 2.5ms I will still get better performance than stock or Splitfire coils, so no need to mess with it.

Finally got to install my Mojo Performance GM LS2 Coil RB26 Kit and here is my Dwell Settings. Is my setting too safe?

I switched from Splitfire to LS2 Coils seems like the rev is faster and more responsive

if it doesn't misfire then all good.. however it's recommended dwell drops as RPM increases.

For the love of your engine check the base timing, I did the swap from Splitfires to LS2 truck coils with 3.5ms dwell time and the timing of the coils moved advancing timing by 15deg which lifted the head and made 4 pistons catch the bores, have now gone back to splitfires

[XKLABA]

What was more interesting was the timing changed with dwell time, changing from 3.5ms to 4.5ms advanced timing 8deg

Something seems wrong there, what ecu?

Change the dwell time on the splitfires and the timing stays rock solid, it was something to do with the coils

Coils may have been fake but bought as new genuine GM coils

Crazy!

So you mean the D585s right? That's some whacky shit. Maybe another reason to stick with the lower power D514a's (assuming the don't do the same thing).

Did you notice any weirdness under 4ms? Maybe this is just the known "D585s go nuts over 4ms dwell" thing.

Yeah D585s, the dwell was set to 3.5ms and at that it advanced timing 15deg, which was tuned around but then they started moving the timing around randomly

I went the D585 because they are COP and much neater conversion then anything else, and now that shit went bad I am finding mine isn't an isolated case and actually becoming a common occurrence with these "smart" coils, info I couldn't find when I researched it before going the setup

It is like they where somehow firing on the rising edge instead off falling edge when they should have been

I am now looking at Audi R8 coils to get the spark I need to run 30psi

[iruvyouskyrine]

I'm sure you have looked into it XKALABA but have heard a lot of good things about yaris coils, nothing on RB's though.

[GTSBoy]

I was going to say the same thing.

[zebra]

Yep many a 1000+hp JZ using Yaris coils

[XKLABA]

I have heard about Yaris coils, Scott @ Insight actually mentioned them at the same time as the R8 ones and they are a consideration but I'm leaning towards the R8 coils because NGK do a replacement and they have a shop at Homebush
