I missed the edit

Whatever the 123tune distributor is doing must be creating or allowing voltage spikes on the coil
If VRIN+ is working but inaccurate, try turning on "Noise Filtering" in the Ignition Settings menu

For those that intend to interface FrankenCIS with a Frequency Valve controlled Lambda fuel head there is a firmware update 5.5.6k available at www.frankencis.com FrankenCIS_firmware_release_556k.zip

This resolves an issue found by 'awjens' where the FV output was reversed or inverted

This is good news.

Cool !!
what did you end up using to get it to work, VR and noise filter or OPTO ?

Table 2 values are now correctly oriented and the allowed range is 0-200 where 100=50%
If you would like the table to be 0-100 and reflect actual percentage just change the “Freq valve Duty to VE%” setting on the Injector Dead-Time page to 2.0 instead of the normal defat setting of 1.0

If you are running the latest version 3 of Tuner Studio it has an internal firmware update tool now
Very simple to use and walks us through the process nicely
Tools Menu - > Update/Install Firmware

Can you explain this in a little more detail for the slower members of the audience, like me.

Sorry, a bit of geek-speak shorthand in that

Basically the frequency valve has a range of Zero to 100% and normal operation is at 50%
with lower being lean and higher being rich

With our standard table setup we have a value of 100 in the cells as normal
so 101 to 200 tunes a richer mixture
and below 100 leans it out
This is with "Freq valve Duty to VE%" set to 1.0 or a 1:1 ratio as we are actually controlling the valve in half percent steps

If we change the setting to 2.0 it then means the table values are directly proportional to the Frequency Valve values
so Zero is off , 100 is fully open and 50 = 50% or half way
this is now in 1% steps so we lose a bit of resolution, but someone may prefer this option

The recommendation is to have it at 1.0 so Table 1 which controls the WUR and Table 2 which controls the Frequency valve are both operating the same with 100 as the centre or normal fuel delivery.

I've been going through the settings and trying to make sure everything is set for an initial start. K-jet w/lambda. I'd appreciate it if the more knowledgeable could have a gander at these and advise if incorrect or insane

AFR 1 and 2 are identical as are VE 1 and 2

a little off topic

would there be any interest in a drop in engine position sensor for the Bosch VR distributors?

The optical CAS I'm using in the above prototype is a Nissan SR20DET unit
the adaptor plate is 3D printed ABS at the moment but will be Acetal or Aluminium
The sensor has been modified by cutting off the plug and bending the pins up to fit inside the distributor housing

This is a 928 distributor so will need to confirm dimensions for a 911 unit before committing

The Nissan unit has 180 effective crank teeth and four cam (360+4 pattern) and that high a resolution needs a good ECU to read it (AEM infinity does!)
there are lower resolution wheels available though

the Bosch shaft is thicker than the usual 10mm Nissan/Mitsubishi/GM setups so a laser cut disc is probably going to be necessary

I'm looking to see if I can use a DSM or GM Optispark sensor instead of the Nissan unit so the hacking of the plug can be avoided

The internal diameter of the 928 Distributor is 83.5mm
if the 911 is smaller I doubt we can make it

rough measurements from photos indicate an ID of around 75mm

Sorry you are having trouble with the Microsquirt, they are normally very tough little boxes.
I've done some terrible things to mine over the years and it's happily kept on ticking.

FrankenCIS does not fit on an 86 930 and probably other similar models.

I found that the damper fouls against the mounting boss of the throttle body.

Has anyone else discovered this or found a solution?
