seperate supply for coil ?

[Not Anumber]

Is it desireable to use a seperate +v cables to the Megajolt and the Coilpack or can i use a existing supply cable (capable of delivereing 15 amps) to the Megajolt, Edis and the Coilpack ?

If you've got the hard rev limiter, the coil supply needs to go through the megajolt anyway.

If you've got the hard rev limiter, the coil supply needs to go through the megajolt anyway.

. Ive factored in running a relay from the MJ's hard rev limiter output to interupt the +v supply to the coil but thats just for switching.
My question is really whether i should aim to use seperate +v cables to feed the coil and the MJ/ Edis in order to reduce spikes in the + supply ?

To minimise interference screened cables are used for the switching signals (sensor to Edis and Edis to MJ) - so what about the risk of the coil creating spikes in the +v supply line that could potentially interfere with the MJ and Edis ?

For instance would it be sensible to run the coil via its own online fuse directly from the battery (with a relay interupt to ensure it would only be powered with the ignition on and below the rev limit set) ? Any spikes the coil could cause on the +v line would be entirely smoothed out by the battery.

This was one of the things I considered, I mean the limp home mode can't work if the supply comes from the megajolt.
