LS1 Coil Packs

LS1 Coil Packs
I am in the process of converting to LS1 coils from my Toyota COPS.
From the research I`ve done, the LS1 coils fire on 5v just like the COPS. So simple question. If I wire up the LS1 coils exactly the same as the COPS, all I `should` have to do is set my dwell to 5.5-6.0 or so. Or will some changes need to be made on my board. It seems like there were some posts about changing out the pull up to something with a lower resistance.
Also, has a recommended cranking dwell been figured out for these coils yet.

So it looks like the one difference between the LS1 and the Toyota coils is the extra ground on the LS1 coil and the tach signal on the COP.
How would the wiring change when going to the LS1. Would the sense ground go to an ECU ground pin, and the regular ground just to the head or something.
What would happen to the blackwhite and yellowblue wires that go to the tach signal on the COPS

Wait, What? I've been lurking here because I have a set of LS1 coils that I'll be putting on my car. It shouldn't be too hard to get a tach output using MS1. At least according to this thread. https://www.miataturbo.net/showthrea...s1+tach+output

MS1 does have a tacho output, bit of an extreme reason to upgrade to MSIII.
To get your MS1 to create a tach signal just build this simple *** circuit, should take all of ohhhh 10 minutes.
