In dash knock sensor monitor

[Steptoe]

MK1 was an analogue meter stuck to the dash top with blutac

MK2 was a seperate powered LCD unit mounted in the clock hole of Project Cheap Grief - my GLA SeriesOne EA82T

It's plastic screen buckled under our sun

MK3 is this new $2 eBay Voltmeter powered and earthed by the former resident's supply. Cig lighter socket lived here.

It should display 5.0 with IGN on, but gives 5.88

It should display 1.7 engine running,but gives 1.6

When a knock is sensed the Volts should rise incrementally from experience, up to 4.5V. As or if this happens, the timing is retarded by up to 10° from experience. It is also incremental or seems to be as the naked brain catches the actions.

Volts signal is taken from the Black/white trace wire at single white female plastic terminal at the ignition coil of 85,86 SeriesOne EA82T that run flapper AFM, white two pin knock sensor and 3 plug ECU, and seperate Knock Control Module KCM mounted between glovebox and body

Really not expecting to see this activate much due to higher octane LPG. I ran it for almost three months with KCM accidentally disconnected and no worries, no audible ping
