Yes and yes.

See my pic two posts above for how to rewire the coils and eliminate the ignitor found on the S1

HAHA This is why I love the internet!!

But thats for the info, its really amazing how smart alot of the average car guys are. Keep up the great work!

Would you be able to run these coils with Nistune? IM running it on Z32 ECU but i dont think you can adjust dwell..

It shouldn't be a big deal to run the coils without adjusting the dwell. I ran mine for a week without changing it and the car actually ran smoother.

Here's some information I've compiled:

Hope this helps other guys out.I couldn't find any junkyard in FL that had them.So I had to pick them up brand new.

Supposedly FL junkyards can't have cars newer than 10 years old. GHEY!!!If you know anything otherwise. LMK

LS2-Coil

History:

Starting in 1997, General Motors used a new (for them) coil-near-plug ignition system for the then new Corvette LS1 engine. The system features eight coils (one per cylinder) mounted on the valve cover, with short spark plug wires to connect the coils to the spark plugs. The General Motors LS1 coils are not just conventional ignition coils. Instead they are complete single-cylinder ignition systems. They contain all the electronics for dwell limiting, current limiting, etc. These coils are controlled directly by a low voltage, low current signal from the sequencer. There is no intervening ignition module (like an EDIS or GM DIS). Because the LS1 coils have the igniters built in, they make for an easy installation and generate less electromagnetic noise in the other wiring under the hood.

About these LS2/Truck coils:

The LS2 coil-near-plug coils are similar in form and function to the LS1 coils described above. The LS2/truck coil has a visible external aluminum heat sink near the connector.

These LS2 coils are incredible. Even compared to the LS1 coil, these are just crushers! On the LS1 coil there is around 40 milliamps of peak secondary current with 5 milliseconds of dwell time. On the LS2/truck coil (AC Delco D585), there is 120 milliamps!

How to use:

The LS2 coil has 4 connections (as well as the high tension terminal for the spark plug wire, of course): A = Coil Primary Ground B = Ignition low noise ground from ECU (ground) C = Ignition digital signal from ECU (+5V) D = +12V Supply to Coil Primary

The two capacitors are optional but recommended. The 1.0 µF capacitor on the +12V is helpful, it is similar to the one used on EDIS. What it does is provide brief energy storage for the discharge. The other capacitor will help eliminate back-fed noise to the MegaSquirt controller. Use a 100 pF to 0.001 µF cap on the TTL trigger input wire to ground. What this does is shunt extremely fast noise spikes to ground and not let them feed back to the MegaSquirt processor. The added capacitanceis minimal - with the series resistance of 1,000 ohms (in the controller) and a 100 pF capacitor the RC 3dB time constant is 2πR × C = 0.6 microseconds.

The LS2 built in coil igniters (the amplifier that drives the coil's primary current based on the sequencer signal) will follow the sequencer signal pulse width. When the signal from the sequencer is high (3 to 5+ Volts - with very little current from the controller, a few dozen milliAmps), the coil current will be building. When the signal from the sequencer is pulled low (shut off), the coil will spark. The duration of the signal from the megasquirt / sequencer determines the dwell (though the coil igniter limits this to no more than ~8 milliseconds).

The dwell should be set at 5 milliseconds input pulse trigger - going longer does not generate any more spark current.

To get 5.0 milliseconds of running dwell, the nominal dwell parameters shouldbe set to:

Maximum Dwell5.5 milliseconds

Maximum Spark Duration2.0 milliseconds

Acceleration Compensation0.5 milliseconds

Battery Voltage Compensation

Setting Net Voltage Dwell Compensation

-4.0 8.0 Volts 2.4 milliseconds

-2.0 10.0 Volts 0.9 milliseconds

0.0 12.0 Volts 0.0 milliseconds

2.0 14.0 Volts -0.5 milliseconds

4.0 16.0 Volts -0.9 milliseconds

This will give 5.5 - 0.5 = 5.0 milliseconds at 14.0 volts while running with the alternator charging normally.

Here is a video of the coil in action - with the LS1 on the test stand you canhear the sparking, not loud but certainly audible. With the LS2/truck coil it sounds like someone is banging on the table! The big resistor you see in the video is part of a voltage divider setup. Its value is 100 megaohm (R1), in series with a 100 Kohm (R2), this pair is across the spark plug. The voltageacross the 100 Kohm resistor is what is viewed on the scope.



Comparing the stock dwell tables between the two vehicles, the truck runs slightly more dwell in the normally used 12-14v cells, but they're reasonably close, and radically modifying dwell time is not the answer.

2001 C5 LS1 dwell table:Click on the link above to see this link

2004 Silverado 5.3 dwell table:Click on the link above to see this link

(I did check a 6.0 LQ9 tune as well, it's dwell table is identical as this one).

Again, for a stock(ish) car, I too would skeptical of any substantial gains, unless the coils just compensated for another ignition weakness, like junk plugs/wires.. But on a tougher-to-fire FI or high compression setup, the truck coils could prove to be of benefit.

http://www.ls1tech.com/forums/....html This is info from http://www.megasquirt.info that i found not long ago,,

:the LS2 coil (GM# 12573190, AC Delco D514-A) from the 2005-2006 Corvette (& GTO and Avalanche), and the GM coil used on 2002-2005 Cadillac Escalade, 2000-2006 Yukon, 1999-2006 Chevy Silverado, 2001-2005 Trail Blazer, and some Hummers, etc.. The model is GM# 10457730 or AC Delco D585 (also Wells C1251, Standard UF262, GM/Daewoo 190005218). The LS2/truck coil has a visible external aluminum heat sink near the connector. These LS2 coils are incredible. Even compared to the LS1 coil, these are just crushers! On the LS1 coil there is around 40 milliamps of peak secondary current with 5 milliseconds of dwell time. On the LS2/truck coil (AC Delco D585), there is 120 milliamps!

We will call the second coil type the LS2/truck coil. These two types of coil have the same connector and pin-out, but the physical mounting pattern is different. The coil connector (GM# 12580353) can be found as:

In case anyone else has the same question.

I'm running the LS2 Truck Coils on the Stock RB20 ECU. Dwell not adjusted.

The car runs soooo much smoother.Also due to the fact that I had a problem.But the engine note sounds a lot better/cleaner.

Great to hear you don't need to update the dwell even to see a benefit in spark energy.

Thanks for keeping the thread updated for all.

Yeah, but Carl is chipping my ecu and going to play with the dwell tables.

But immediately I heard a difference when I fired her up on the first try.

Hopefully the next guy will find this info helpful.

Would you be able to post up your dwell tables?

Essentially all I did for the dwell tables was to run a static 5ms dwell across the board (5.5ms at 12v). Unfortunately each EMS has a slightly different way of representing dwell. The AEM has it is weird timebased units, the PFC is in degrees to my understanding, and I'm not sure what the stock ECU is in.

I would just tell the tuner to put it in static 5ms dwell and they should be able to convert to whatever units the stock computer needs. Otherwise if you know what the units are I can convert them for you as well.

post your aem cal please. thanks

Whatadsm- I'm not sure what the units are.CARLH is Tuning the ecu for me.I'll let him know what your running.

Thanks

yikes

you guys have saved me SO much trouble and expense, I have been looking for a way to get rid of the crap coil packs for about 6 months
would it be to much to ask for you to e-mail me some instructions with some pics along with which connectors you used and where to get them please, sorry for any trouble I'm still new to import muscle

hey whatadsm i have question for you (or anyone that might know the answer). On the aem ems you simply use the ignition wizard and select chevy corvette ls2 ignition and call it a day or do you have to manually set some values? if so, which ones?

Working on the r33 today I was looking at the stock coils which looks to be weathered. I then released I had a set of LQ4 harnesses, mounts and coils on a shelf. I am going to be doing this swap too seeing I need to tune as well.

Hey i was wondering if this would work on a rb25 s1 with rb25 nistune?

yes.

I gotta take pics, I mounted mine using threaded rod, and aluminum stuck above where the factory ones were. I had some stock LS1 spark plug wires layinig around too, and they worked perfect.

Here is a distant pic

Hello!
Thank's for the great info!!!
I've made such swap and the car now drives excellent!
But now I always have Error 21 Primary Ignition...
How do you fix it?
RB25DET NEO with Nistune...

Bump for KavVeMan

I also I have the Ignition Code (running Nistune) I don't believe there is a fix you could email Matt directly he replies quickly

Its looking for the ignitor so its going to throw that code.

i dont have an ignitor on the NEO tho neither would a series 2

Sure u do they are built into the coils. Since its not the same I'm sure the ecu is freaking out over it.

I have a series 1 and never had a CEL pop up after the coil swap. I was running PFC at the time, so maybe that made a difference. Does the car run like normal but throw the CEL anyways? Or is there an ignition misfire that is initiating the CEL?

rehost the pics!
