And since I kept the old ignitor in place i pulled power from the old coil

Anybody having issues with the Bosch Motorsport coil? My first lasted a week and now I've just had my second in a row fail on me after a month and I'm starting to wonder if there's another root cause here. Both times it was during a huge rainstorm but all the connectors are full of dielectric grease and have rubber boots.
I've tried searching for causes of repeat coil failures but Google isn't finding me much that seems relevant. I'm going to have to keep track of which side of the coil is going bad to see if there's a pattern.

I've mounted it above the valvecover on a bracket I made to bolt to the old distributor mounting holes and hold my wideband plug, ignition module/amplifier, and coil. I've seen others mount it above the valvecover via the valvecover bolts so maybe my bracket has too much vibration?

EDIT: Problem vanished overnight. Hooked up oscilloscope and found perfect signals so I took it all off and found a bunch of water mixed with the dielectric grease. Revised bracket to correct positioning of the ignition amplifier, hopefully for good this time:https://imgur.com/a/9rD65re

I'm currently stuck with no grounding from the ignition modules (I'm using two standard modules as I bought a new one to test previously and found both to be working fine.) I've added my voltage readings below with ignition on. Has anyone else taken these voltages so I could compare?

5V - 5.3v
VR - 2.4v
1-4 - 7.7v to 8.2v back and forth
2-3 - 6.9v to 7.4v back and forth
Spark - 0.33v

I've never installed one of these, but since no one else has replied, I'll take a guess.

Your 7volt / 8volt whatever measurements are way too high. I think those should be logic level outputs of 5volts, or less on average. You could unplug your WS-to-ignitor cables and re-measure, or check that the ground on your ignitor modules are good. I'm wondering if the ignitor ground isn't connected, but ignitor +12v is connected, and that the +12v is raising the WS output voltages.

The 1-4 and 2-3 output voltages should never be above ~2.5V. So yes, it appears something has been wired incorrectly.

Can you explain what you mean by "I'm currently stuck with no grounding from the ignition modules" please?

If you have time, take a clear photo of your EZK with the board wired in, and post it here.

Ended up being a failing EZK, it had been struggling on and off for a while with ignition problems. Unfortunately, one of the pads on the wasted spark board came loose on removal from the old EZK so I've ordered another!
