Note: it is recommended to split thematically to several pages. (inputs, outputs, other wiring details, issues, etc...)
MembersPage/PerH/VemsWiring - detailed wiring is necessary to be able to help.
- (from the response last month, still neglected, apparently preventing effective help): no wiring details provided
- The method of debugging is to reproduce the setup (or parts of it) or review .vemscfg according to the detailed wiring.
- This is impossible if one or the other is not provided (or apparently neither, in this case).
- The method of debugging is to reproduce the setup (or parts of it) or review .vemscfg according to the detailed wiring.
- Important: Detail your wiring grounding. See GenBoard/Manual/GroundConnections
- Device will get damaged if grounding is not good.
Always examine the Validate ("check" icon) from Vemstune (after "update ini files from web"), that might draw attention to important issues or suspects.
Publish the uptodate (.vemscfg) config (and .vemslog if "dynamic" behaviour can be interesting) in case of any outstanding problem. That could allow tech crew or someone to reproduce your setup and perhaps find something that can help you.

Introduction:
I have a '72 1300 GT Junior, and mounted a 2000 GTV race engine with 45 Dellortos. Now i'm in the process of installing FAJS ITBs and the following equipment:
Trigger: VR primary using standard 60-2 wheel from Alfa 75 TS and a custom sensor mount:

HALL Secondary trigger using the distriutor (welded the centrifugal advance shut):
Other sensors are: TPS, IAT, CLT, Map (VEMS module), and one knock sensor (https://photos.app.goo.gl/GVaZPkz6Tbzyhf47A).
The VEMS 3.3 was ordered (by a friend of mine, who didn't use it) like this:

Ignition is a standard Bosch ignition module running a motorcraft coil (wasted spark).
This is my wiring list (note the multiple sheets for compartments).
__________
With everything connected, I verified that all sensors except primary trigger was functional.
Problem 1 (VR Trigger): SOLVED (solved by "lifting" p259 VCC and soldering it back and now works?)
Problem 2 (Relay outputs):
Problem 3 (ignition outputs?): SOLVED
