Help! DIY Mappable Ignition
Turbo Mini Forums

Hi a couple of months ago in Retro car magazine it had a how to on DIY Mappable ignition, which use a home made circuit board and components from Ford EDIS, like the module, coil pack and sensor. Here's the web site www.picasso.org/mjlj

So i was wondering has anyone used this setup? and would this set up work on a Turbo Mini and how hard would it be to set it up?

cheers

So i was wondering has anyone used this setup? yes

would this set up work on a Turbo Mini? yes

how hard would it be to set it up? not so hard, if you know abit about electronics.

Fastest 998 mini in the world? 13.05 1/4 mile 106mph

I'm running it!

And as it happens will be fitting another to a mates engine in the next few weeks, so if you want any pics of a particular part then PM me.

i'd love to get this, if you could do a little how-to that would be ace. I see most of the EDIS parts are available on ebay and a fully built controller is only about ?75.

At last i can get rid of my dizzy, bloody thing is sooo close to the rad!

gibbo that would be great, when i first saw it i looked into it a bit. Where too do you get your electrical componets from? like the vaccum sensor?

what about mounting the crank sensor? how do you do that?

A bit like this.

It's been done a bit neater since

nice pic, just had a reply from a chap u can supply all the parts ness for a full system...


Hi, thanks for your email.
I can supply you with a kit that will give you a distributorless setup. It will also give you the option of using fuel injection (easily added by using a jenvey 45mm 2 injector throttle body @ about ?145)
I can supply the parts to give a distributorless mini at the following prices.

Megasquirt ECU modified for Ford EDIS ignition control (still maintaining fuel capability)
(inc. Basic Loom fully soldered with labelled ends, Software, Documentation, Serial Cable)
?240

Ford 4 Post Coilpack
New: ?60.99
Used: ?15.00

Ignition Module EDIS4
New: ?145.99
Used: ?20.00

Trigger Wheel
New/Used: ?15.99

CPS Sensor
New: ?24.99
Used: ?8.00

Used parts are thoroughly cleaned, and as they are solid state, do not really suffer from wear.
New Parts are Genuine Ford.

The only fabrication necessary with this setup is to weld the Trigger wheel onto the Crank Pulley, and to create a bracket to mount the CPS sensor. (both simple jobs)
I can supply a ready fitted trigger wheel and a CPS sensor bracket at extra cost if desired.

This is an ideal system for a boosted mini, especially if you use the injection setup aswell.You could easily upgrade to a Throttle body at a later date using the same ECU.

Hope this helps.

yeah i can get all the pats myself from a Ford dealership i use to work at, and all the software and stuff is on the internet so i'm not bothered about that, its just the electrical components neede to build the ecu part of it. Cos when i looked into it i couldn't find anywhere that sold a vaccum sensor cheap enough?

do you know where you mate gets his electrical components

soz i was just posting that for everyones elses info, unfortunatly i dont know where he gets them from, he's just someone i found on the net who can supply the kits.

matter of interest, whats the vaccum sensor for?

i think its for the ECU to know when to advance and how much? i think so i remember there being one on the part list. Go onto the website at the top of this thread

I would just also like to say that retro car mag said that u could build this kit for ?150, mmmmm we'll see

ah y i see it now. I think if u built the kit yourself it would be a lot cheaper, just depends on your electronics skill level and time!

Personally, with a 60hour a week job and two kids i would have it built for me!

I managed to get most of my components from work. But I did order the map sensor from digi-key.

It might be possible to get a map sensor off another car, but i haven't looked into it.

All the Ford parts came off a 1.1 1994 fiesta, except the trigger wheel that came from a 1.8 sierra.

The EDIS is a EDIS4 unit, beware there are some old EDIS units that have a pipe on them for a mapsensor that aren't suitable.

The pic above shows a 998 crank pulley without a damper, the 1275 engines have a damper on the pulley, so you may need to modify the rad bracket slightly.

Apart from that every thing else is covered on the mjl site (www.picasso.org/mjlj ).

Is not running a damper advisable? I am converting to a grooved belt (blower) and am having serious thoughts about how to get a grooved crankshaft pulley AND fit a trigger wheel. Bearing in mind my realistic top end will be 6500. At a total push...

Bugger off, I'm getting there.

would you notice a power increase if so how big do we think, surely with mappable ignition it can open up a whole new idea on the quest for more power, maybe someone can buy the parts and make some kits up to sell to us lot at aprofit of course!

when i was on digi-key a couple of the compents on the list wasn't found in their catalouge, and the description they give isn't clear engough to find it in another catalogue.

Gibbo did you make the whole thing your self?

Post up what your short of and I'll find you an alternative part.



All the parts are available from Digi-key, there's a direct order page on the picaso website, but import tax and shipping from the US is a bit high.

The picture above is infact a 'damper pully' it's just been machined down to fit the timing wheel on.

Looks like the best idea rather than just bolting it on like I did!
Mine fits but it fooking tight lol

so Gibbo, do you rekon its best to get all the other components from electronic catalouges in this country and just get the vaccum sensor from america?

how much did it cos all together in the end?

dont forget import tax, that chap who makes the kit (brent picasso) emailed me to say that when he ships he puts a $75 dollar value on it (the full premade kit) so i doubt customs would be too bothered to be honest. I'm seriously tempted to go fully mapped, the cost is comparible to a good aldon dizzy and coil!

p.s. can u get dizzy blanking plates?

Just machine a plug and hold it in with the dizzy clamp

here are some photo's of my mapped ignition install

That's som geinus wiring Jim

As I mentioned before, I obtained a lot of parts from work, so I don't have a list of parts you can just go to maplins and buy sorry.

Due to the low price of the pre-built unit, I'd be tempted to buy one next time. It's not worth the effort sorcing your own parts at that price to be honest.

If I remember correctly, I think someone on the mjl site had found a UK vendor for the MAP sensor, so it might be worth asking on there if you are determined to do it ultra cheap!

the wiring was easy, I know it looks mad there, but I made a diagram before hand, and there was no two wires the same colour. Although this did cost a bit in the first place, it made it much easier
