That should be a cool deal for those who can't build there own.

For us Luddites, can you explain something? If the crank sensor tells the system where the motor is, why does it need a cam sensor?
Does this use 8 coils, with a wire to each plug? COuld it be used with coil on plug in a 426 Hemi?
THanks, Joel It works great on a 426 HEMI since the HEMI is an RB block. Yes, 8 coils with a coil to each plug. ****** Below is from my web site. There will be a quiz afterwards!!! ****** Why go CNP? Coil-Near-Plug is used on almost all modern engines. OEMs do this to virtually eliminate ignition noise from modern heavily computer populated cars. It eliminates the ignition coil and distributor, and it also allows for individual cylinder timing adjustments. Spark energy increases because the coils have plenty of time for dwell saturation regardless of RPM. And EFI data logging is so robust that a separate data logger is not needed. A Quick CNP Tutorial The ECU must know when to fire each coil. There are two ways to do this: Waste spark with missing tooth trigger wheel: When the ECU sees the gap on a 36X or 58X trigger wheel it knows that the engine is coming up to TDC for either cylinder number 1 OR number 6 (assuming a 18436572 firing order). It cannot tell which coil to fire since both are coming up to TDC, but only one is starting the power stroke while the other is starting the intake stroke. So the ECU will fire BOTH #1 and #6 coils thereby wasting a spark. This is an acceptable technique that can be used if there is no cam sensor, however the trigger wheel must be a missing tooth style, and individual cylinder timing control is not possible. Sequential spark using a CAM sensor: A cam sensor generates one pulse, or edge, per camshaft revolution. This allows the ECU to be in sync with the engine’s cycle and fire only one coil, thereby not wasting a spark, and the ECU can also control individual cylinder timing. Since the cam sensor synchronizes the ECU to the engine cycle the crank trigger wheel does not have to be a missing tooth style. A typical configuration would be a trigger wheel with four magnets and the pickup. However, you can use the 36X or 58X style wheels with a cam sensor as well. In fact, the missing tooth wheel is preferred because the timing is more accurate during rapid changes in engine RPM. Using a CAM sensor is better than the waste spark method.

I see you have the ign1/Holley coils. I just put a set on a guys car to replace a set of "heat sink" GM coils. The car now has a quiet, yet noticeable high frequency "buzz" sound from the coils with the key on/ engine off. Do they all do this, or do I have something going on?

I would love to put one on my 572 hemi, but until I finish the car, I have to hold off on modifying things....Rich, is it possible to put a dual sync without having a separate crank sensor, something like the jeep one? Tim

Does anyone make a cover (cap replacement) for the old Mopar steel/iron distributors? I have a small block tach drive distributor. I would like to go to CnP, keep the mechanical tach and not have to leave the empty distributor cap on the distributor.
Bill Not that I'm aware of, but I'm sure someone could make one.
