Hi All,
So I've finished creating my engine loom and the car is running and idling on Speeduino
I do unfortunately have sync issues at 2000-2500rpm and 4000+ rpm. The rpm goes like crazy and sync is lost.
- I'm using a Ford zetec VR sensor on a 60-2 trigger wheel.
- Using the v3 conditioner with 4.7K 3w R10 resistor (also tried without).
- Set trigger edge at RISING. Not using a filter yet.
- I'm using this shielded cable: https://www.aliexpress.com/item/5M-24AW ... 4c4d3E77Uk. Is it a bit thin but that shouldn't be an issue right?
Below is a few pictures of my oscilloscope connected to conditioner input and output pins.
First question: Is the VR polarity correct? The MAX9926 is a reverse type...
I do have a air gap of around 1.5mm.
I still have options left of trying filters but currently I have to many questions like the polarity, cable used and air gap.
Any help would be very appreciated.
Melvin
