The Ignition Pages
This area discuss some of the ignition options that are available on GenBoard. Along with that, are discussions about timing technique, parts, availability, and other research.
Ignition Topics
- EdisIgnition - Ford EDIS System where we calculate the spark advance, send (1536 - spark_adv_degrees * 25.6 ) usec SAW pulse to EDIS, and EDIS takes care of the actual ignition timing relative to crank position, dwell control and spark generation. EDIS uses it's own VR input from 36-1 timing (crank-)wheel so you'll have to add this to your crank.
- DwellControlIgnition -
- DummyIgnition - Taking care of dwell control. To make sure the coil is charged sufficiently.
- IgnCalc
- IgnitionPage/COP - Coil Over Plug technologies.
- IgnitionPage/TransformerWithAmplifier - coil with builtin driver
- IgnitionPage/TransformerWastedSpark
- TimingLight - See this page for a very simple DIY timing light
Q: are the COP off a BMW M5 3.5,3.6, or 3.8ltr diffrent?
what do
- part numbers
- mechanical and
- electric
Q: how can I use GM LS1 (???) smart coils which have built in drivers. Can you get some links to the documentation ? Maybe aliases (other names for the same , part numbers) ?
- [check on this page] (or actually [this]) if it's not another well-known system with another name

Is there any chance that there is no such thing as "GM LS1 smart coils" because LS1 is a car (corvette?) ?
LSX are 3rd gen chevy engines
LS1 >> C5 corvettes, 98+ f-bodys, Holden Munaro, Commodore and ( chevy caprice and lumina in the Middle East)
LS6 >> Z06 corvettes
LS2 >> C6 corvettes and 2005+ pontiac GTO
LS7 >> will be on corvette Z07
there are also 2000+ truck VORTEC engines that have the same ignition system but with hotter sparks
each of these engines has 8 coils "CNP" and uses a variable reluctance type camshaft position sensor

I've read that these coils have built in drivers and considred as smart coils

download this pdf file it has some info about LS1 ignition system
[LS1.pdf Dead Link!!] According to the drawing the "smart coil" has an NPN inside (maybe same type that Keith bought the other day). However it might just be a draft. It's easy to verify (eg. with DVM: the Base-Emitter of an NPN drops about 600mV).
Here, you can buy several ignition coils, wires and several usefull things: http://www.nology.com/products.html
I recently found a very nice system that is used to upgrade the stock Honda ECUs to have all the unlimited tuning power the standalone ECUs.While learning how the system works i discovered that the Hondas that use VTEC (variable valve timing) use 2 different and independent(!) Ignition and Injection tables for low speed cam profile and for high speed cam profile.

Would be nice to have this feature.(also with dashboard switch switchable,so race and road modes can be tuned for eco and maxpower)
Hackish told me on the IRC that we have multiple maps already. How they work is not known to me
