CNP/COP using factory ECU and FAST eDist?

LTCC for the GN?

I make a device for running LS1 coils on LT1 cars, its called the LTCC.

I have also run LS1 coils on my GN.

Bob,
Do you have any plans to make a bolt-on GN product like your LTCC?
Would the Fast-Start conversion be useful or required?

yes, many plans.

there are several ways to do 'fast start', the 3x18x style stuff is interesting. I'm not sure the average user is going to want to do all the extra work.

I have a pre-prototype that runs, but I loaned it out.

Its a matter of having time to work on new stuff, I hope to make more progress on it this season.

Bob,

Interesting you would suspect that. The one time the motor ran for any length of time is when the coils were getting power from the ignition or when coil power was grounded thru triggering circuit. I have tried using power from ignition housing for one bank of coils, but no joy. With both banks drawing power, motor started altho that blew the fuse. I'll check cal to see if I can force bypass mode. Otherwise I would need to hack harness which I am not inclined to do. Thanks. Keep you posted.

you might try putting some big resistors in to take the place of the coils. The module may be looking for a certain amount of current draw. It may also be looking for the voltage spike from the coil kick-back.

Let me know what you find.

Sequential spark idea

I've been trying to get around to this but haven't had the time. I was thinking of using the factory ign module and seting up a regulated voltage divider to tap into the coil signal and then sending that through a set of j-k flip flops to demux it. Then I was going to use darlington pair's, one for each coil, triggered off of the demuxed spark signal to drive the COP. I think it could work and was considering adding an optical pickup to the cam sensor to reset the f-f's for starting and redundancy. With this setup it would probably be best to use the slow start system so the spark would be sync'd before the fuel started. I just don't have time to mess with it right now and I probably won't for some time. I anyone is familiar with electronics workbench I could send you a rough schematic to show you what I mean.
