what you say does make sense

Iam wondering why mine fires at TDC because normally the timing is retarded to make it easer to start but not sure if only done by software in ECU or wether its the magnet positions or wether it see a north pole first then a south and decides where the piston is, maybe like you say the magnets do need to go either side of the logo and when first flicked ignores the first and fire on the second untill running which to me means the first magnet at TDC at the moment could have be wrong polarisation as well ?????
