The States look cheaper initially but then you get stung on bloody import duty, then VAT on top of that! - I remember my Engine/rods/pistons/clutch/flywheel getting held for ransom when I had to collect them!

I'll be buying an LC1 Wideband, as I saw the write-ups on them on the Megasquirt forums.

It's going to be an uphill struggle getting this lump running but we'll get there!

[Ruishy1]

i dunno, it wasnt me that bought it, was my mate.
Got it from USA, was the higher spec innovate kit for a little less than over here.
More kit for roughly the same or a little less.
Know what i would go for.
Ive bought other bits from ebay.om, and its always been cheaper than over here, unless its for large items in which case HMRC usually gets a cut.

there not cheaper unless you prove it post up some links its not hard ,when did your mate buy it ??

i THINK it was ebay.com, this was 2 years ago granted, and the exchange rate was a little better.
It hasnt fallen that much though.
His car is on a metro forum, his username is brownjamie14, you can search for it as i cant be fooked

Jimmy small parcels usually sneak through and you dont get the 27.5% vat and duty whacked on top, i got my uncle in florida to re-send things and mark them as gift to avoid this

[heeman10]

It's fallen 19%, and was even more favourable the year before. I was waiting for the moment to strike when buying the rolling road at the time, saved a packet by holding on just long enough

[dangerousdave]

dangerousdave - yep you were right about the on-board 21 psi MAP sensor! No bother though, I'll still use the FRS one that I bought for the signal to run the boost gauge on the FRS dials...



Apparently I need to change a transistor for a more powerful one to drive the Ford ISCV that I'm using as the Megasquirt is normally used for stepper-motor type idle valves

sounds like you got it all sorted mate

cant you run megasquirt without an iscv? or at least a better one than the ford one?



i was also looking at buying from the states but as you said, by the time youve waited weeks and paid the import tax customs charges etc its not worth it,

[jimmyesh]

A bit more progress!

Thanks to "cowie20" on these forums I now have a full FOCUS RS wiring loom which he sold to me for a very reasonable sum, thanks again mate

Seeing this box of wires took me back to when I built the MANJ and had to decipher a whole ST170 loom!



I went through it this evening with the Ford TIS CD and have identified the parts I require. As you have seen in earlier posts, I'm using the Focus RS Clocks and consequently need to use inputs from the engine and Vehicle speed sensor to supply the ECU with the info that it needs to drive the clocks. I have pinouts for the FRS 104-Pin ECU and should have this little lot sorted soon enough...

Also, as the FRS dials incorporate a boost gauge, I have a FRS MAP sensor which will provide the signal for the ECU to drive that gauge.



I am using other features of the Focus loom too, such as the twin cooling-fan drivers (using cyl-head temp sensor & ECU), the outside temp/ice warning sensors, the Ford Passive Anti-Theft (PATS) system and keeping the alternator wiring to the ECU.

I'm going to pare this lot down to the bare essentials to save weight/clutter and generally to only keep what's absolutely necessary for it all to work.

I should have the driveshafts back from recoprop this week and have started making up the engine loom for the Megasquirt, the coil packs and injector loom is all sorted and looking rather neat even if I do say so myself! (will take pics next time I'm in work).

[rob pace]

was that exhaust you picked up from me a good enough size for the engine you have?

[jonboisescort]

loving this car just as much as the manj

great work fella

[jimmyesh]

was that exhaust you picked up from me a good enough size for the engine you have?

I'd say it should be fine mate - obviously I haven't had it running yet so it remains to be seen. For the power I'm after I reckon it will be just fine

:D

loving this car just as much as the manj

great work fella

Cheers buddy

[Ruishy1]

the suspense is killing me
your going to slow mate

[jonboisescort]

[cowie20]

i tried to get it in box neatly mate but wasnt happening. glad its came in handy to someone...the longer i kept it it could of been chopped for spare wires.
good luck with it mate, cant wait to see it finished

[frostie]

jim i dont know if you know but the frs has a feature where you can get engine temp sensor ,inlet temps, digital rev, digital speed and a load off other features on the clock just above the mileage counter! you have to hold the mileage reset stalk down when the car is running then you keep pressing it to go through all the options its very kool

[jimmyesh]

Just been on the phone to M-Tech Automotive in Wiltshire, they supplied the ECU to my friend for the Golf engine.

Luckily I have confirmed that the loom & ECU is definitely configured for C.O.P ignition and works in wasted-spark mode so both wires marked "Spark A" go to coils 1 & 4 and both marked "Spark B" go to coils 2 &3.


The bad news is that I have no provision for boost-control solenoid unless I get a driver added for about £45

Better get busy sorting the loom this week!

[FRSJON]

sounds good mate but a nightmare at the same time...

[jonyb4]

oh my that loom is so scary, and theres me crying over mine!

keep it up mate, im ever more getting excited over this car, maybe it could be ready for some shows later this year?

keep at it mate

[jayrs]

would be worth the extra 45 notes though mate

[jimmyesh]

The loom looks a little less scary now guys! I've been chipping away at it for an hour or two every night with the TIS CD, my ECU Pinouts and a huge pile of wiring diagrams/connector views.

To be fair, I don't need a great deal of it and am keeping only what's absolutely necessary for my instruments to work

I spoke with someone who's very experienced in this field yesterday and basically as I'm using two ECU's (MS V3 for engine, FRS for dials, anti-theft & cooling fans etc) I need to add another crank sensor to drive the Focus ECU (for tach driver) as misfires can occur if you try to share the CPS signal between two ECU's. It doesn't have to be accurately mounted either as it's only for the dials and is not actually running the engine so can be sited anywhere between 0 & 360 degrees. Luckily the Duratec lump has the trigger-wheel mounted on the outside of the cam-chain cover, behind the crank pulley so it shouldn't be too hard to knock up a little bracket

[Rhinopower]

Can you not use the tacho output from the ms ecu to drive the frs ecu?

[jimmyesh]

Right everyone, couple of new developments

Firstly, I returned the Megasquirt V3 to my friend and am not using it any more - I've been chatting to some well-known ECU-tuners who can remap (hack into!) Ford EECV ECU's and am going to run the engine on the Focus RS ECU as well as the clocks! It means ditching the C.O.P setup but in many other ways the 104-pin EECV is more sophisticated than the V3. It seemed stupid having a powerful ECU that's already designed for an inline-4 turbocharged Ford just sitting there driving the clocks!

Here's the ECU...



I'm still working up North in Catterick for another couple of weeks so took my box of Focus RS wiring up, and also my TIS CD and full pinouts for the Focus RS 104-PIN EECV - my mates think I'm both mad and sad at the moment!

Here's what a few boring evenings have produced - I have completely stripped the engine loom back to the ECU connector and re-made the loom to suit the layout of my Fiesta MK3 Engine bay + back-to-front Duratec HE engine. I've left most of the sensor connectors off for now though so that they can all be added once I have it all in-car once I'm back down south - it will all be tidy and use the normal Fiesta MK3 rubber boot that covers the ECU. The ECU will also be mounted where the MK3 Fez item normally lives.



The driveshafts have arrived from Recoprop and as you can see, they are almost equal-length. O/S one is 380mm, N/S one is 355mm so hopefully torque-steer shouldn't be as prevalent as it is with the normal Fiesta transmission



Exciting times - things are looking up!

[jonyb4]

oo that is a smart option mate, i mean what them rs ecu's cost? im guessing around £60-£100? seems a wate having it run only your instements

that loom is scary stuff mate, id faint at the sight lol

im in bit of a pickle on where to mount my ecu, the si loom is designed to ave the ecu liek you said in the mk3 position juster hanging under the bulk head, well a mk4 (my car) its futher down int he foot well

i might put it in the pollen filter lol im not allergic to anything that i know of

nice update mate, your one of my biggest imspiriations for me doing my own car

[jayrs]

sounds good mate, would be a waste having that ecu doing jack really, and i love the weay you go out side the box on things, most would do this and those that did would use aftermarket ecu etc

keep up the good work mate

[Ruishy1]

sounds good mate, always nice to try something new, but if your mate wants to sell me the megasquirt for the price you got it il have it

[Excursion]

Good news mate

[RS rob]

good stuff jimmy,
a good decision made there!!

[FRSJON]

nice one jimmy

[jimmyesh]

Cheers for the kind words guys It will obviously need a fair bit of re-mapping to suit my engine but there should be no problem at least getting it to start/idle on the Zetec/FRS base map as the sensors I'm using are FRS items or share the same parameters as FRS items so here's hoping!

I'm also using the Focus RS relay box ('Battery Junction Box') so that will be getting some special attention from my fair hands this week!

Once I'm back home in Colchester properly I can go to town on all this and things will hopefully move quickly - they need to as I'm back out to Afghanistan in October for 7 months and from now until then we're going to be in training and away on courses so I need this car done!

[Ruishy1]

you should have an FT day mate, we could all come down and lend a hand, get the car done in a few days

[jimmyesh]

Hello everyone and happy Easter

Had a full day working on the car yesterday and finally started to get my modified Focus RS wiring loom fitted...

Firstly the dash was removed to make things neater/easier towards the end when I'm hooking up the wiring to the Inst cluster/OBD Port/PATS/Fiesta fuse box;



As I'm using the Focus RS ECU and loom, I also needed to fit a Focus PATS tranceiver so here it is;



As per my previous updates, I pared the original Focus RS loom right back to the ECU connector and started from scratch, reconstructing it to suit the layout of my Fiesta's Duratec engine bay. I'm using the standard MK3 Fiesta ECU mounting location so here is the bare loom emerging from the passenger footwell!



This job is extremely time-consuming! Basically I left all the connectors off the loom so that I could tailor it exactly to my engine bay, and heat-shrink each individual "branch" that goes off to a different part of the bay then soldier the relevant connectors in place (been triple-checking the wiring diagrams and ECU pinouts at every stage! ) - we're partially there in this pic...



Here is is as I left it last night - most of the engine bay components are all connected now, including earth leads etc. As I've needed to revert back to conventional HT-Lead ignition due to using the FRS ECU, I've had to re-route my hard boost pipe slightly (see pic) - no hardship, I'll get that sorted soon. As you can see, I'm also using the original MK3 Fiesta ECU wiring rubber "boot" for neatness and also, The Focus battery junction box - this allows me to run all the ECU, PATS, sensors, dash, fans, fuel pump etc with the correct fuses/relays already in place. I'm also using the Focus relays in this box too such as, Starter relay, Engine run relay, Fan relays, Ignition relay, fuel pump relay. As a result, I'm only keeping the fiesta fuse box for the lighting, heated screens, central locking etc.



Here's the wiring that needs hooking up to the dash,OBD port,PATS,Starter button,fuel pump and the fez fuse box. Not too much really as the ecu and engine bay wiring that uses the battery junction box all gets taken care of under the bonnet. (sorry for the grainy pic - crap mobile phone! )



Got a bit more to do and I have an extra week's leave after my wife goes back to work in a week's time so going to beast it then!

[FRSJON]

its great to see progress on the car looks like a bloody nightmare though

[Ruishy1]

Good to see your making progress mate
your a braver man than me, just looking at that wiring is making me sweat

[jonyb4]

lol aye me too, im confused like mad lol

glad some of us can comprehend these things and make awesome cars liek this, its really starting to take shape now mate, the final stretch is soon

keep it up man

[jayrs]

excellent progress mate

[RS rob]

rather you than me with all that wiring jim
you must have wicked patience for that

[cowie20]

f**k yeah mate, awesome build! am so glad i got that gotech because if i didnt i would off been doing that on the loom to get into my car.

[moondustka]

It's good to see someone spend so much time on the wiring and making it look factory - to say the least! Excellent job there.

The electrical world gets so bodged way too often - whether it be cars, houses or commercial places.

This fiesta is soo unique!
