wiring the crank sensor and oscilloscope

Post by pule333 »

Hi again. maybe wrong section.
tried today to crank the engine for the first time. no joy.
i have a dry sump set up with a trigger wheel on the pulley and a magnetic sensor.
first question, how can you wire a magnetic sensor wrong? its only a 2 pin sensor. are they sided?
below is the oscilloscope. is there something immediately obvious that is wrong?
its a 30-2 wheel. crank mode 0.

cheers

also another question, i have wired my coils as per diagram. coil per plug. but have no cam sensor. is it vital? or I must wire them differently as wasted spark?

The wires on the crank sensor are the wrong way around. Swap them, and try the scope again.

If you have coil on plug, wire them to each ECU output in firing order (assuming you have at least an S60), and then tick twin spark in General Engine Settings. This will run the COPs in wasted spark.

thank you Alex again! would have never thought you can wire it wrong haha.

woohoo it worked. it started. not very well as most other map settings are way off. but it started.
also I need some new pins for the plugs where can I buy them?. and also would like to buy that rotary switch is DTA website not taking orders at the moment?
Thanks
