I purchased VEMS with the following:

1 x Assembled v3.6 controller

- 1-wire interface: no

- withSDcard: removable

- PS2 connection: no

- secondary_trigger: HALL

- mounting-style: no-screws

- MAP connection: 400kPa (5/3mm pneumatic)

- LCD connection: no

- EGT input: 1

- Flyback: 30V flyback

- ignition driver: 8

- Knock input channels: 2

- primary_trigger: EC36/27 VR $845.35

1 x Wideband connector

- With wire: with crimped wires $14.10

1 x Econoseal10 wire-wire

- Sex: pair $13.38

1 x K-thermocouple connector

- mounting-style: panel-mount

- Sex: pair $16.64

1 x VEMS sticker

- Color: metallic: silver

After the purchase a different engine was bought and now needs a sec trig with VR not HALL like ordered.

Here is what i've done so far to my board to convert it from secondary trigger HALL to VR:

I've now put a blob on LM1815 at the bottom side under the FETs.

I also removed the connection between SOT23 NPN base and collector.

After doing both of those things and verifying that my VR cam sensor works with a multimeter I still have no reading on my trigger logs.
