You didn't say anything about the French model's girlfriend, though. HEHEHE;)

Re: Anyone care to guess...
 

That commercial cracks me up everytime I see that smirk on the French Model's face.

Jep, that project sounds promising. Excellent R&D!!

Dom,

They are not GM. They are from a high horsepower, high revving 5.3L V8. I'm not going to say any more at this time.

They are 3 pins. BAT+, GND and trigger. Trigger high to start dwell period, trigger low to cut primary current and fire the coil. I have a scope so I can get data on dwell as installed in the OEM application. This data can be used to populate the cells in the LS1 PCM coil dwell table.

This will be quite cool.. especially if it works with the CCM

Re: Anyone care to guess...
 

Part of the issue w the LT 5 ignition module and LS coils. No way to modify dwell. The LS coils use 4 wires w +, power ground, ECM ground, and trigger.

Re: Anyone care to guess...
 

Dom,

I can understand that, since dwell is entirely controlled by the ICM. The dwell tables in the LS1 PCM will allow folks to choose what coils they want and tailor the PCM to properly trigger them as long as:
a) the coils have built in driver circuits (smart coils) or external driver circuits are used and
b) the coils or external driver circuits use a TTL level trigger.

I know that you and others here understand this, I'm just spelling it out for the benefit of others who are reading.

Don't hold me to this, but my intent is to have my car in BG running on the 411 PCM with full cluster, cruise, etc. functionality with secondaries deleted and COP pencil coils installed. I may or may not achieve that goal. We'll see.

Assuming that all of that goes well, I will begin work on a solution that integrates full secondary functionality. That will take more time, though, as it will probably involve modification of the PCM code.

Re: Anyone care to guess...
 

how is this progressing?

Re: Anyone care to guess...
 

Jep, Got an add on for you. Anyone out there want to make up a CNC aluminum din rail to hide the wiring? Could be held down by cam cover bolts. This could be fully customized with any logo added to the top.

Re: Anyone care to guess...
 

Robert,

I've already ordered and received the 6061 aluminum bar stock to do this. I will have to do the first set manually on a friend's milling table, but once I get the fit(notice that I din't use "fitment") worked out, I will produce a cad file for reproduction.

Re: Anyone care to guess...
 

Jeff,

1) I'm finishing up the wiring harness mods.
2) I have ordered and received one of the COP coils pictured previously to be used for testing.
3) Today I received my EFILive FlashScan V2 and software to load up the base tune and for follow-on tuning.
4) As stated in my previous post, I have the aluminum bar stock to machine the billet coil/wiring covers(rails).
5) I have received the stock needed to machine the crankshaft reluctor mount. I still need to obtain the stock for the sensor mount.
6) I have started working on the base tune to get the car up and running.
7) I'm still waiting on a benchtop programming harness(to load tunes onto PCMs while removed from the car) and flanged Deutsch connectors to attach the coil rails to the coil harnesses.
8) I think I've found a suitable PCM bracket, but haven't ordered it yet.

To all,

Keep your eyes on the For Sale section. I will be posting some stock parts up within the next few days. All profits from these sales will be dedicated to funding this project.

Thanks for your interest and support,
Jep
