EDIS 4 module

[Bonzo]

Hi folks.

Today. I have been mainly soldering again.

This time I have built a Megajolt unit for my lads project. :rolleyes:

The surface mount components were a lot easier to solder than I thought they were going to be. Sooo tiny.

I am now looking for the source of an EDIS 4 module.

The one I took from my 1.8 Escort Zetec donor (1994 car ) was mounted on the nearside inner wing. However I have been unable to find another at the breakers.

The Escort Zetecs I am finding are newer & look to be complete, no sign of an EDIS module though. :confused:

Have Ford located them in a different place or is it that Ford has done away with them & are now running the coil pack direct from the ECU :confused:

Has any one got any idea as to what car to be looking out for & location of the EDIS unit.

The EDIS comes up on ebay from time to time.
When you get one mount it in side the cockpit not the engine bay, our engine bays get hotter than Fords and the EDIS is vunerable to excess heat.
MegaJolt is best mounted close to the EDIS and on some sort of shock mount to lessen the vibration.

Heres a pic of the Megajolt unit that was built this afternoon.

This was bought direct from Autosportlabs in the states.

Quick delivery & lots of info on their web site.

A lot quicker to build than the Megasquirt. Although the surface mounted components are tiny. :) :)

Hi Ronnie

Looking good there. As I see you're playing with both the 'jolt and the 'squirt, I was wondering if you knew the answer to a question I have. Can you run the megasquirt as an igntion only controller (i.e. the same as the megajolt). It seems to me that the prices aren't that different, but it would be an very cost effective upgrade solution to simply by a megasquirt, run it like a megajolt, then when you want to go for the full monty, just add injector and wiring.

Cheers

Hi David

Yes I beleive you can use the Megasquirt for spark only. There are a few options available to suit just about any budget.

Number Two son, has visions of fitting bike carbs to his spare Vauxhall Calibra XEV engine. :eek:

[davidimurray]

Hmm I see a plan forming - dam stop it David, build the car first! I've been involved in injecting two previous engines, allthough we had the luxury of a Motec M400 to play with. Even thought we had over £1k of ECU to play with it's amazing how simple things like a poor connection in the loom can cause all manner of troubles - been there, done it, spent 54 hours with out sleep trying to find the problem!

[Bonzo]

Yes, faulty connections can be a real problem to detect. Even more so when they are of an intermitent nature. :eek:

Having worked on a fair bit of marine electrics. I have over the years learnt to carefully solder each joint or connection & then seal with heat shrink tubing wherever possible.

If I am in one of my anal moods, i'll do a continuity test as well . :D :o

hi bonzo
if you need an edis
try trigger-wheels on the net or big-wasa on locostbuilders

Just completed the instalation of a complete V3 system after discovering some loom problems on my V2.
Built up a complete system on a board in the Utility room (with the Pinto race head on the chopping board next to the ironing) checked all the wiring several times and used shielded twin core properly earthed (unlike the original loom) then spent 2 days carefully wiring it in to the car, separate fuses and power supply, soldered and heat shrunk, replacement EDIS and Coil pack.
I am sooo hoping that my cutting out problem has been solved.

[Bonzo]

Fingers crossed for you snapper :)

The importance of good quality wiring can never be over stressed. ;)

It is so often, very tempting to use scavanged wires for critical components .

EDIS 4

Yes indeed they do turn up from time to time on the bay.

The reason I was asking about suitable donors are two-fold .
Firstly if I can remove it myself, I get to have the plug, VR sensor & coil pack.
Secondly, If buying other things at the breakers at the same time, all of the above will be thrown in for next to nothing if not free. :D

Twas up the breakers last week. Needed an alternator for my nephews Mondeo.
Whilst I was about it, I removed a pair of good 2 litre Zetec cams to use on my 1.8 build.
Charged £10 for the alternator, cams thrown in for free !!?? Bargain. ;)

More and more problems with the Megajolt so wired the jolt, edis and coil to the battery (with a simple switch so i can turn it off) runs fine to 4500rpm then pops and bangs.

This is what i did to isolate the fault, with the total help of the Autosparkslabs forum.

Run car, 4500rpm ignition fails
unplug Megajolt, start car ( car should run at 10 degs from EDIS alone) rev to 4500, ignition drop out.
replace EDIS, no megajolt rev to 4500, ignition drop out
replace coil pack, rev to 4500, ignition drop out.

At this point i should add that i have a complete V2, EDIS, Coil pack spare.
I have rewired the loom with all new cable and proper shielded stuff for pip saw and VR sensor.
I have replaced VR sensor, cable and plug previously

replaced VR sensor with older one, no spark at all, threw it in the bin.
Noted face of VR sensor has been shaved by toothed wheel and slight marks in the side of sensor from locking bolt.

Replaced VR sensor with one from Trigger-wheels.com, revs to +5500rpm no problems.
Take it for a spin achieve 6800 red line.

The only way to check the sensor is to use a scope but its the VR sensor (and bracket) that is the weak link so check that and the plug/cable first.

Hope this saves people some angst

[Bonzo]

That information may very well come in handy for future reference. ;)

Those blooming sensor problems can be a real barsteward to diagnose :rolleyes: :(

Is all well with your setup now !!?? :)

[snapper]

Ronnie, so far so good.
I will be taking the car further afield as the weeks go by (carrying spares of every thing) with AA card in hand.
Project 2 is to rebuild the Megajolt V2 on a board with sensor and plugs as a complete plug and go testbed.
Project 3, is a rebuilt 2.1 Pinto with Cosworth Rods and V6 pistons, this will have a much firmer VR sensor bracket. The one on my car was built for a fast road Sierra and is to low for safety.

[Bonzo]

Good news then :)

You can never have enough spares ;)

I have been quite lucky on my last few visits to the breakers. Found a few Edis modules, a few spare coil packs, 1 nearly new & lots of spare sensors.

Keep up the good work, you may be my savior at a later date. :D :o

My next modification is the twin ignition map modification, all the wiring is in place on the V3 Megajolt ( and i may open the V2 to do the solder wire mod) but i do confess to having great difficulty getting the firmware upgraded to work.
My biggest problem is that i use Macs most of the time so when it comes to using the home laptop my brain shrinks and hides in the corner of my skull till i feed it beer, then the laptop has won, again.
