For those interested in MegaSquirt EFI...
Here is everything you need to do the conversion! 
Complete EFI inelt manifold and sensors.
Astra VXR 480cc injectors for up to around 220bhp, Siemens Deka IV 630cc injectors for more than that.
Zetec Coil Pack, Supressor, FRST Plug Leads.
36-1 Trigger wheel, VR Sensor (or EFI Flywheel/CPS and EFI block, or drilled MFI block)
Fuel hose (Filter to rail, and return).
EFI Vacuum hose to Master Cylinder.
MFI to EFI head adapter plate, and gaskets.
MegaSquirt MS2 Extra V3.57, and loom.
FRST EFi Throttle Cable.
5/8 Take off for CC pipe to ICV.
Dizzy blanking core plug (not pictured as it's arriving at my local Ford dealer tomorrow).
MFI to EFI pedal modification.
Total Cost was £675, you could save yourself about £95 by getting second hand plug leads, throttle cable, and not buying braided fuel hose,
bringing it down to £580, and even more money if you want to use other second hand injectors!
Plug wiring diagram for standard Inlet assembly loom! Saves chopping all the individual connectors and allows you to just unplug the entire Inlet assembly in one go!
Coolant and Air Temp Sensor setting for MS using standard Ford XR2i/XR3i EFI sensors!
Air:
5C........ 71900
36C...... 18300
100C..... 1900
Coolant:
5C........ 71900
36C...... 18300
100C..... 2000
FRST Air Temp Sensors are different and are as follows..
4c....... 5000
36c..... 1345
100..... 170
Hopefully will be fitting by the weekend at the latest!

lmao i turned loads of hand towels into drying rags or for wiping my hands lol, so this conversion why is it done, is it because its just better then mfi?

Pretty much yes!
MFI cannot be mapped all that can be adjusted is the fuel pressure and static timing, going EFI means you can use brand new parts (sensors, injectors, wiring etc..) and gives you full control over your fuelling and ignition timing through out the rev range making the car more reliable, responsive, economical, and powerfull!

hmmmm economical i like the sound of that lol, mind u having a rs isnt good for someone looking for a job 
i may look into saving for this conversion, looks easy enough to do

have you stripped all the old wiring out of the loom yet to do with the mfi ? started the same conversion on mine last weekend when i ripped old motor out hopefully have it all in and running by this weekend if all goes to plan

Can't see it being any cheaper at all.

good guide, you can use any injectors with megasquirt, so don't hold back to a certain type.
also you can modify the coil pack to use escort rs turbo leads using an 8mm drill bit in the holes from the coil pack to leads and cutting the plastic back on the outer case of the coil pack for the leads, that'll save a few quid if you already have good leads.

It's my MFI pedal with a small plate welded on the end to use the EFI cable.
Thats very true!
Basic loom comes with the MS, but you have to fit all connectors, and heat shrink it etc.. No dont think it supports ALS, but it does have launch control and boost control!
Spot on there!!

Karlos, after reading this lot last night and my mate also reading it who's into electronics we are now between us planning on the same conversion for my cabrio over the winter months, my mate has already fitted mega squirt to his own car (1.6 16v astra 1997) just for a little project of his own, he also added bluetooth to the system and has a pda for displaying info or can connect to his laptop, He reckons it will be a lot easier to do my turbo.
He reckons we should use a wideband lambda sensor on the system to aid mapping ease, he also mentioned fuel pump which brings a question you may be able to answer
Is the standard erst fuel pump up to the job?
So now my shopping list begins, I will be keping a close eye on your progress.
I'm also hoping I can sell a few of my old mfi bits to recoup some costs after conversion as its all in great order with no running issues

I have std rs turbo fuel pump, car is running 0.9 bar of boost with no any sign of pump problems.
I have wideband lambda sensor too, it is "must" thing with megasquirt.

Standard pump is more than up to the job it runs 6 bar on a MFI RS and you only run 3 bar for this EFI setup
WB Lambda would be great, it saves sticking one up the arse of your exhaust and using a seperate gauge! I just have not got one to save costs and Doug who is mapping it with me has one.
I will get one in the future though, as coupling that with some Det Cans gives you all you need to tune your RS!

rs turbo fuel pump would be fine for up to around 250bhp, after that fit a cossie external one, that'll run 300bhp.
as for wideband, i highly recommend it, how do you know what's happening without one.
also you'll need a lambda anyhow for the ecu to make it run nicely and not too lean/rich on low revs.

), the car will run just fine as long as it has been mapped well!

I recommend wideband lambda, because it is pretty cheap life insurance for your engine. 120£ for innovate kit is not bad, or is it? I often make some little tuning and adjustments for my rs turbo program and i always do need wb lambda. Best thing in megasquirt is that you can map and tweak program when you want and little modifications such as cam timing or exhaust may change how engine works and need some mapping. Would you take it _every time_ in expensive mapper when you change something in your car? Second thing is that megasquirt runs nice in closed loop mode, megasquirt do read wb lambda all the time and you can adjust how much is lambda authority to adjust, i have 7% EGO mixture correction adjusted when engine is warm. All modern cars run with ego correction in roads, why should we not take that option?
Even if you have really sharp mapped program, there is always some closed loop tweaking and you can adjust target areas in different driving style. Basically i have 15 afr target when driving easily in highway. Then if i put a little throttle and boost say 120kpa there is something like 13.5 afr and if i floor it and put 200 psi pressure in to manifold there is 12.5 afr. Get the idea? That is important thing in fuel economy. My rs turbo runs 5 litres / 100 km when driving easily. 56MPG
I hope you all folks can understand something about my bad english essee

Hope you got the MS set up for what your running. Just been trying to set one up on a Zetec turbo 
Its been almost 3 years since i set one up and there a pain

I was ready to run my FRST on MS about 9 months ago. Had to put the standard ECU back in as I was moving 450 miles away and I've never got around to putting it back in, mainly due to lack of a decent base map.
If you suceed in getting yours going, would you be willing to share your early maps? Ignition map was my real concern.
What volume do the astra injectors flow?
Cheers

PassionFord Post Whore!!
will you share base map with me too please karlos???
Also what trigger wheel set up are you using, looking at the picture is it a universal wheel attached to a pulley, is it welded to the pulley? and is it a homemade cps position bracket? is this going to be attached to the cambelt cover or something else. I should be ordering a lot of my parts in the next couple of weeks

Yes mate of course!It is indeed a universal trigger wheel welded to the pulley (centered and then 2 dowels put through with the ends welded), and yes it's a home made bracket for the VR sensor and uses one of the oil pump bolts to hold it in place.
