woohoo step into the future (finally)

[Mk1Sport]

well ive finaly put my order in for my megajolt ecu!

now i can finally throw away that stupid distributor, and get 90BHP from my little 1300 escort

[Mk1Sport]

ok question; does anyone know where i can order a crank sensor mounting kit from? im on limited time, so dont want to mess around getting them made up

[Mk1Sport]

burtons do a kit for around £80 this includes trigger wheel and all mounting accesories, and crank sensor with all mounts aswell. does anyone know if this crank sensor would work with megajolt?

[Stevie]

should do m8

[dangerousdave]

Is it the weber one? If so i would say no as you need to use the ford sensor, but at the end of the day its probably exactly the same sensor in a different casing! I would save the £80 + vat and just make one, youll be able to do it before the kit could be posted to you

[MegatronUK]

Get a trigger wheel off ebay and then get a pick-up, EDIS module and coilpack from an Escort, Fiesta, injected Sierra CVH, or Mondeo in the scrappy.

Check the wiring - the EDIS system is very sensitive to interference on the lines from the crank sensor and tps, if you make your own, make it's good quality shielded cabling.

Dosent need to be expensive and the bracket to fit the sensor is easy to make

[neilm]

C'mon Ian... you are being a little biased here.. being a man who is good with his hands, or so it says on the toilet wall at Ace Cafe...

You and I both know that the positioning of the sensor is critical, it needs to be exactly 90 degrees from TDC and also the distance from the trigger wheel needs to be correct too.

The weber kit comes with everything to bolt straight onto a crossflow and all the thinking and working out has been done for you.

Give Troy or Steve at Northampton Motorsport 01604 766624) a call,they always keep one on the shelf and they may be a little cheaper than Burtons... you never know.

[Mk1Sport]

thanks neil that was my thinking.

oh and dangerous, i would go the 'make it yourself' route but i cant make jack shit because i got nothing to make it all with therefore dont have time to mess around getting ten different ones made and finally finding one that works properly. at least the burtons kit is (almost) bolt on

and do northampton motorsport have a website? i live in new zealand...

and would a weber crank sensor really not work? after all its just a simple little electronic component, they all do the same thing and work in the same way? right?

[Mk1Sport]

oh never mind... i found the website for northampton motorsport... it was www.northamptonmotorsport.com go figure...

[Johnson]

The bracket isn't that difficult to make I found the throttle one to more of a pain on the ass.





I have a pdf with the dimensions for a TPS bracket here I can mail you if you want it?Its for 45's (Dellorto's) and I had to modify it to fit my 40's but it works well.

[dangerousdave]

Johnson that looks cracking mate, much neater than mine how did you attach the trigger wheel??

[Mk1Sport]

tps bracket isnt a problem for me, im going the MAP route...

will let you all know how it turns out!

[Mk1Sport]

would it be possible to get an even vacuum without a collector/plenum if equal length hoses and t-piece intersections were used?
for example like this...


or perhaps like this, if you join runner that fire 180 degrees out from each other (ie 1,4 and 2,3)


my thinking is that when the pulses arrive at the intersections, they will 'smooth out' because the hoses are equal length, they will take the same time to reach the t-intersections

or will i need a plenum?

Ahh, my ECU can have the trigger where ever it wants, you just have to dial in excess amounts of advance relative to where the gap is, I think I run 66degs of ign advance at cranking, I would think most ECUs should have this facility

[dangerousdave]

I would just use tps dude its a lot easier, plus if you want to use it on a turbo engine later on then the weber map sensor from a cossie fits the same plug for the ford mondeo tps most people use over here, you just need to swap 2 wires over No need for internal map sensor then!!

[Johnson]

Cheers Dave,

Whilst we were playing with the lathe at work we turned up a spacer to fit inside the boss of the crank pulley then I just drilled it all and put a roll pin in.

Whilst we were using the lathe we also made one of these



To go here



I have attached the pdf for the TPS as well.I take no credit for the design it was done by another Westfield owner.As I said I had to modify the design for mine but it would give you a good starting point.

I would not bother going MAP based either not with twin carbs as its not worth the hassle and you will probably end up switching to TPS anyway after you have ripped all your hair out in frustration .

[dangerousdave]

Ah right i can see that now! Did you use a standard or solid front pulley? im guessing standard

And if you get a chance can you make me up one of those dizzy blanks? Il happily pay

How long til you pop round in it then? cant be far off surely

[Johnson]

Hehe I will add your name to the list of people who want blanks made up.

I have struggled with it all lately as I have been working at head office on Technical support for the dealer network for a month.

That's now finished as of yesterday and I have next week off so hope to crack on with it then.

Still have to fit my floor mounted pedal box,tidy the Megajolt wiring up,mount the number plate light,lower it some more,change the wheels(maybe),adjust the suspension geometry,get it on the rollers and MOT and tax it.

Doesn't sound a lot when you write it down does it?

I know the missus has jobs for me to do as well.....

Plus I have to fix a couple of other peoples cars.That's why I am up at this time today.

I was going to post some pictures of the car but not sure if I should put them in the New school section or somewhere else??

Anyway back to the topic

[dangerousdave]

Old school restos mate and the lists tiny comared to mine thats why im up at this stupid hour too

[Mk1Sport]

thanks for the advice everyone, but its too late now my ecu has already been shipped!

and after a bit more thinking, i'm just going to drill some male hose fittings (with threaded ends) into each intake runner, collect them together with t-pieces (like my diagrams) and then use a biggish fuel filter as a balancing plenum! works out nice and cheap! and perhaps the filters will act as a 'pulse-damper' aswell?

no tricky little adapters to make!

oh and johnson, i was planning to have something like your 'dizzy bung' made up, and weld a plate to it so i can mount my coil packs in the same place the dizzy was! still looks a little closer to standard that way

i plan to have this all running in a few weeks before i leave to the airforce, so i'll keep everything updated to let you all know how it goes

[Mk1Sport]

how far up the intake runners should the hose fittings be drilled in? closer to the cylinder head or carbs? would it make much difference?

[Johnson]

Damn it I just wiped my last post.

I would have thought nearer to the head personally.Happy to be proven wrong though

[Mk1Sport]

would this work?

would it create any vacuum problems if the hoses joined each other so close to the I.R's?

this way would be a lot tidier...

[Mk1Sport]

Mr Brent Picasso says that this will work fine...


so thats the way im going

oh, and if my MAP version doesnt work then i'll modify the circuit board for a tps instead, but for the sake of science im going to try it this way...
if it does work then we will have turbosport members with experience with both TPS and MAP versions of megajolt

[DaveWRC]

Anyone want to make me a crank sensor mount and triggar wheel spacer? I will pay pray:

[Mk1Sport]

Anyone want to make me a crank sensor mount and triggar wheel spacer? I will pay pray:

ahh ya beat me to it! the burtons kit is back-ordered 4 weeks
i might just have to get everything else in set up in the mean time

[DaveWRC]

I've been dreading sorting this side of things out for ages. I'm thinking of buying the burton one and getting a machine shop to copy it then returning it

[Mk1Sport]

now theres an idea


oh and ive been trying to contact northampton motorsport but they wont email back could be because of the easter break i guess.

[Johnson]

Dave I can knock one up for you but I am not back at work till monday week,then I have to go to Millbrook for 3 days testing some cars.

I guess to be safe you are probably looking at a two week wait with me unfortunately. Happy to do it if you want though.

[Mk1Sport]

well i finally recieved my megajolt ecu today!
been shopping for a few things, heres what i have...

megajolt itself


two fuel filters sprayed black, im going to use these as balancing plenums for MAP. i used two different sized hydraulic fittings (5/16" and 3/16") joined together to act as a 'step up/step down' adaptor to connect the 5/16" fuel filter to the 2mm or 3mm vacuum hose... the 3/16" fitting is a bit tight, but hey its the smallest i could find...



and i'll get one of these tapped into each intake runner, probably going to use the shorter ones (on the left) and trim the threaded part so it won't stick out into the manifold too much...

[Miniliteman]

would this work?

would it create any vacuum problems if the hoses joined each other so close to the I.R's?

this way would be a lot tidier...

Connecting the vacuumhoses together does not work at all in my experience. Whenever people are using Megajolt type aftermarket systems I advise strongly not to use a MAP sensor with independant runners. The MAP will only work with a large plenum. But then I don't know everything maybe Graham B has some other experiences.

[Miniliteman]

Ahh, my ECU can have the trigger where ever it wants, you just have to dial in excess amounts of advance relative to where the gap is, I think I run 66degs of ign advance at cranking, I would think most ECUs should have this facility

66 deg advance at cranking??? Hope not!

[DarthVader]

Ecu I use has similar function - im running 40Deg

[alladdin]

im guessing people are talking about the ability to input offset figures for timing ?

im under the impression that loads of m/s ecu installs are utilising the map feature with independant runners without problems ??????? i also agree a resevoir as a damper is a good idea.

[Mk1Sport]

yeah, heaps of people are succesfully using the MAP feature with megajolt, take a look at the forums here...
http://www.autosportlabs.org/

oh and i think what v8ian is saying is that its not absolutely critical to position the crank sensor 90deg BTDC of the missing tooth with the crank pulley at TDC... if you are, say 10deg out either way, you will just have to adjust all your ignition timing values either a further 10deg advance or retard, so while you have excessive ignition advance at the ecu, in reality your advance values are perfectly normal

[Dan]

will be following this one with interest popcorn: .. hopefully it'll be my next project, once funds have recovered from the gearbox and rear disk conversion.. mines a 1300 too so should be good to see what its like afterwards

[DarthVader]

Correct Alladin - variations in timming can be dialed out with ecu software.

[EscortDan]

That is the route we went with the crank sensor, it was simpler to put it 90 deg past top TDC as there was a way of mounting it there, then just adjusted the timing values on the laptop hey presto it started!

Don't ask how many trigger wheels marc destroyed!

[Clint]

I am just putting EFI on my Fiesta Xflow, the timing wheels in these pics are the ones I make and fit the front pulley perfect, I will also me doing a weld on adjustable sensor bracket for the sump




I am using Weber management though as soon as I get it running I will post some more in for so people can copy me.
