The relay output and the two programmable outputs in the newer design aren't necessary at all, I just added them because there was space and thought someone might find them useful.

For sure they will be a handy addition for some users applications.
Nice work.

Cheers

After a fair delay I now have a few more of these units on hand. The new version is the same as the old but with the addition of two rpm based programmable outputs (for switching a relay,shift light,etc). Have also made a few changes to the instruction manual to include the newer versions of the un...

This is completely different to the VL400 module. The VL400 module is programmable including its own dwell settings and replaces the factory ignition module (Its also no longer made). This one retains the factory module and piggy backs its output. Thank antus, although that snippet above about the ...

LS2 D585 & D514A not recommended.

Is your LS Coil Driver different to VL400's LSx Coil Driver possibly ?

In the notes for that LSx Coil Diver it has the D514A as being know to work.

So how do I know which coils are not recommended ? I do know of one or two who have used these IGN-1A Coils with a LSx Coil Driver box (Not your SilentBob) supplied through this site. Both had Kalmaker tunes applied & as far as I know no issues yet, apart from a bad earthing issue in ones wirin...

I had some issues with the d585 coils when testing. In reality it's probably not going to be a problem, but it's easier to not recommend these types of coils to save someone the hassle of finding an issue if it comes up. So how do I know which coils are not recommended ? I do know of one or two who...

The protection is a thing with most the LS coils. I dont think it'd be a problem, > 5ms dwell is a long time. Handover to PCM is usually 400 rpm, so with a safety margin you could measure what dwell the stock coilpack provides and subtract 5ms and if it travels less than 10 degrees in the time of t...

No, it is effectively a capacitor in series with the signal which will bleed off the voltage going to the mosfet/ignitor inside the coil. It doesn't spark when dwell is exceeded, it just slowly discharges the coil energy over a few mS. It heats up the ignitor but there won't be a spark at all. If t...

Hi SilentBob, Coils with overdwell protection ? Is that possibly the IGN-1A type ? Hoping not. Cheers Coils like the LS2 type will discharge if you try to have a dwell period that is too long, greater than about 4.5ms. When the dfi module is controlling dwell (during cranking or fault modes) i beli...

Following on from VL400s thread https://pcmhacking.net/forums/viewtopic.php?f=11&t=3065&start=150 , I've made my own version of the LS coil driver box. This thread is for discussion, questions, people wanting one, etc. The ECD (Ecotec Coil Driver) is to convert the DFI coil signal to allow ...
