Hello 400PrarieXLT. Yep, the single black strip is a zero ohm resistor.

Gougeonit. I wonder why it even needs to be 1khz. Seems to me that an engine running at 6000rpm has a trigger coil that only triggers at 100hz. So I am not sure why the timer needs to be 1khz, much less 3khz.

BryceGTX,
At one time the modules only put out 70 hz to 540 hz during testing there was speed drop on the top end. Yes the frequency from the speed censor doesn't put out much to change the timing but it was found that a higher frequency did help to keep the speed up. Since then the module frequency has been raided from 540 to 3000 or slightly more now. This one shown has an output of 1100 hz I beleive this timer will handle a higher value of 3000 hz without any problem. Hope this helps.

 

Hey alltoys. Do you think the trigger coil generates multiple pulses per revolution? Or does the higher frequency force the timing to go beyond its normal advance at high speed?
Thanks BryceGTX

 

BryceGTX,
After the quad reachs a certain speed the OEM cdi puts out 28* no matter what the frequency is output to the cdi. Now when the cdi reachs 6500rpm the OEM cdi loses timing again it doesn't matter what the module puts out the cdi it will detune itself. This is why modules only work on the bottom end. Through a stronger bottom end acceleration given by the module it will help in a given distance but top end is not effected at least with the newer modules.
