Auto-electrician Genius Needed

[Martin@PRD 0]

Just before I go and cut out my Glassfibre dashboard to fit the mass amount of gauges and switches I have been collecting, I thought about fitting in a Nos controller I have (Twisted Sanity).

 

As there isnt enough space for an extra controller needed for the other engine I was wondering if there was a way to control the two extra solenoids with one controller, knowing that each solenoid is powered by pulses and needing the correct voltage/amperage for activation there would be no chance of it communicating correctly with the extra solenoids as well, but If I had the controller connected to a relay or two controlling each pair of solenoids would this work or will it require a special relay to produce a clean pulse?

 

Any ideas would be much appreciated

Should be OK if you fit the solenoids parallel to each other.

The only problem with running 2 sets of solenoidsa in series is that you will draw twice the amount of current the the controller, If this isnt a problem then you should be fine mate.

Running them in series or parallel direct from the controller will course problems, as the controller needs to power them as well as being able to talk.

 

The only way I could think of at the time was again to use a relay to power them while the controller can still talk with the relays for triggering, though Im not sure a relay could handle pulses without some kind of delay or irregular pulse, as each solenoid requires the right frequency to operate correctly to perform progressive activation, power staging and charge mixture.

 

Here is a quick picture of my planned method.

As long as the combined current draw of the two sets of solenoids doesn't exceed the controllers maximum (written in the instructions?) The controller will just 'think' there are two large solenoids and not four, surely?

You'll have 2x the resistance which will slow the speed of response.

 

What you really want is a mosfet transistor switch. This is basically a solid state relay which will cope with the fast rate of switching. You split the trigger line as you have done. Then run it into 2 mosfets.

 

Finding suitably rated mosfets shouldn't prove too difficult. But if you need some help i can probably find some bits that would work.

Hi Fella, Yes that would be great and thanks for the useful info!!!!!
