The one thing I always liked about the LT5 was what a good looking motor it is. No cosmetic plastic covers to hide all the ugly. Just all functional motor. You might get better performance and I hope you do but............Sorry guys that looks like a Rube Goldberg Chinese fire drill.

I agree with Brad, you guys are amazing with this electronic stuff! Kudos!

May I be second in line? Please. Anything that will prolong the life of our DIS box is worth trading a little "good looks" for, JMHO. Car will not be much use if the DIS lunches & ya can't find a replacement or some place to fix the brain box.

Interesting thread. Maybe the coil used on the 2007 Audi A3 would work? It would fit down the hole nicely.
Watch for new thread on this.
Here's a price sheet and vendors for the part.

Very nice...

I think your CNP system would be a nice addition to my PNP ECM. It could allow you to get rid of the wasted spark methodology.

You need to find a way of using the 9 slot reluctor on the crank or install an LSx reluctor and sensor. I'll be interested in seeing what Jep comes up w in adapting thee 411.
Ron,

The MS shouldn't be an issue supporting CNP OR COP but again would need reluctor/sensor.
Our setup converted the IM grounding of stock coils and used it to trigger the LSx coils. However, they fired in waste spark mode, ie in pairs. So the IM became a "sequencer". So we didn't eliminate the IM. I know that a similar scheme was used successfully on the GNs. The difference however is that our IM has much more capability built into it. The GN module was dumb.

RHanselman · 05-02-2013

The MS still uses the 9 slot reluctor on the crank and uses software to convert to an LSx type reluctor and sensor signal. No additional hardware needed... This was one of the initial requirements. The IM would not be used in this situation.

I plan on exploring the COP version on my Turbo Car.

Ron,

Would MS develop a stand alone sequencer to use the existing 9 slot crank signal and fire COP or CNP?
