As usual, check in VT help:
[VT help knock configuration] is one of the best step-by-step guide
- just follow the steps, do NOT skip (if skipping, on your own: do not complain or ask)
- before asking for tech help or support, make sure to have followed the steps, show it explicitely having done so, and also indicate which step seems problematic and why, how (expecting what, measuring what ?)
If missed to order VEMS ECU with the correct number of knock input - or need some deeper diagnostics:
See GenBoard/Manual/KnockInput
Knock sensors
Any sensor (that is used for acoustic knock sensing) should work with GenBoard. The frequency and gain can be configured in software. The frequency depends on engine (mainly bore and cylinder head) while the gain depends on several factors (engine, sensor, screw fastening torque).
It is recommended to verify that sensor can be mounted well. Cling the engine block with a wrench and record the sensor output with your soundcard to measure frequency and verify sensor operation and connection. Especially if the engine bore (the sensor was originally ment for) is very different from yours (say a sensor for a 50mm bore mounted on your engine with 100mm bore)
