Which electronic ignition?

Unless you want to build an ignition system for fun, I'd stay clear of building your own and buy one. There is a big difference between hobby electronics and electronics designed to operate reliably in the harsh environment of a car engine bay with the associated heat, vibration and voltage transients. It took the car manufacturers until the 1980's to make underbonnet electronics reliable.

Jaguar couldn't be counted in that...and the Aston Martin Lagonda...well :oops: :oops: :roll: :roll:

I am a electronics engineer and what you tell here is partly the truth, I have knowledge to make it reliably very easy with the modern components like the ignition power mosfets who are special made for this. This ignition can be very good, and yes I now the build need to be very good, a small mosfet driver under the bonnet and the rest inside the passagers room wil do work fine.

The processor used here is very reliably and special made for this tasks. But I need to test it and I will do that when I have the rover. I have a mercedes W115 and build in a transistor ignition, and never had a problem with it, just put it outside moisture, encapsulate in resin wil work perfectly.
I do not now who good is the program who have to be program in the chip, it is just testing and wee what happens.

Now there's an opening for you .
You make them and the P6 boys will be knocking on your door
 
It is entirely impossible to protect an electronic design in electronics unless you hold a patented circuit or process, all that can be protected is the copyright of a PCB board layout or direct wholesale copying of the product exterior which maybe copyrighted.

I would hazard to guess that early unreliability of car electronics is solely down to car makers employing designers with a poor understanding of device parameters and or poor real world understanding of the automotive environment.

I use a Pertronix Ignitor on my old Triumph. Apart from a tachometer compatibility issue(tach not working)it has been superb for the last 7 years. My father has the Lumenition Magnetronic fitted to his P6B which I believe is the best for reliability and stealth with no unsightly amplifiers on display.

I had found the Simonbbc ignition systems didn't really work for me. Other than being a low cost initial purchase, I found the finite life span a little inconvenient to say the least.

Invert the tacho signal with a single transistor of mosfet?. most the reason of this.
 
Controller of parallax is quite modern, I go make a test soon, possible retune the software also, IT has to be
used with original ignitor, but weld the centrigual weighs tegether to disable them.

Then use handheld programmer and drive, if oke, program remove programmer.

Best is afcourse to use the original chart, and use a LPG chart here.

Nice read.

Not only rover drivers knocking on te door but also other classic owners . I do still think this is not my own
design, I do NOT steal, so I ask first,

I've got Lumenition, no problems with it at all. Also had Lumenition on a Scimitar many years ago and likewise, no problems. Doesn't go wrong, doesn't wear out, works well, not hugely expensive, what more could you want?
 
Hi

These one can adjust ignition advance in steps with a controller, this you plug in and afterwards removed when done,
it has also a posibillity to program the best advance for LPG gas, it do automatic switch between benzin and lpg if you
want that with a single wire.

It uses heavy duty mosfets for low ohm bobine, do switch bobine of after some time not runnning with kontakt on.

Yes you need to build it, I have still to examine it, special the software for the parallax processor.

Why on earth would you want to build this ?

1) The electronics he used is a $10 prototyping board.
2) His website was last updated in 2005
3) in his own words 'This code has not been tested'...
4) ... "I'm not a programmer, this is the first thing I've ever written"

HI, the same question could asked of anyone of us that own, drive and repair 40 year old cars
that have not been updated since the 70s :wink:
Because he can and wants to. :D

I have a Lumenition with original coil on my car but it dosent start that well. Plus, i really dislike the big block and yard of wires attached to it so im thinking of putting a new one in. Just need to work out how wire it all up now.

I can rewrite the program if needed, the board is for al ignition schematics very simple.

That the man say I am not a programmer is strange, I think that he has find it maybe somewhere, if no
programmer then he can not write the software, what he did or get from somebady else, also
the code is nog so difficult for a advancer, using timers.

I do try later on if I have a rover found, I have look to one but it is wet inside and one side off the bottom and
inside sill is rusty and thin. I like to find a place for a new inside sill on the right side seen from front of the car.

Motor did get to much benzine in one carburetter.

I can simulate electronics and also ignitions, I have some more designs here. Even a injection setup.

regards.
