all the above motors running off of V2.2 boards, VB921 ignitors and LM1815 conditioners where applicable.
90% of them are running the Hi-Res 09C Firmware.
Any More details on the 20v? Such as:
- 3 wire or 4 wire coils (Assume 3 wire since you say you used vbs)
- Dwell Settings
- Wasted Spark or Sequential?
- ...anything else you care to add ;)
iv got the 4-pin coils working here (on a turbo'd rover k-series) at the moment car is off the road so not driven it yet, but got dwell at 2.6ms (found on the net somewhere, again not scoped) and these coils need driven by a PNP transistor that pulls the signal pin UP to +5v .. the COP's have an internal pull down resistor of around 120ohms so any attempt to drive them with the conventional transistor/vb921 and a low value pull up resistor jsut results in a weak spark or no spark atall.

Running dwell 2.6ms and cranking dwell 3.0 ms. Driven by 4 x VB921, however just for the reliability. Spark Output Inverted = NO.

- Connected according: http://www.msextra.com/manuals/MS_Extra_Ignition_Hardware_Manual.htm#2coils
with pull-up to +5V for the COP signal (I believe 1k, but I'm not 100% sure).

Please note that you need to set SPARK Output Inverted to NO !
If you want to use the drawing for the Manual feel free to do so.

I had to swap 1&4 and 3&2 to make it run because MS2 assumes that the second trigger is used to signal the opposite 360 degrees of crank rotation compared to MS1. It seems to run fine, though I am tracking down some noise.

COP can have a built in ignitor....this is similar to a VB921. If they are built in, you don't need vb921's but can trigger direct from the PCB.
If they don't have built in ignitors you MUST use vb921's.
Did I get that part correct?;
If so, how do you tell what you have? My COP are champion pieces, and thats about all I know. They came with the engine i'm currently fitting.
If they have built in ignitors, then you could still drive them from the vb921 anyway, they will just be under very little load?
