Over the last year I've done a lot of reading/research, asked a lot of questions when speaking to experienced mappers, until I was satisfied I had enough knowledge to try it myself.
Key is not to guess anything, if your not sure then ask someone that knows

Thanks for the comments mate, i'm very happy with my results

as above, it's not so hard when you figure what every little change does.
i found it hard work when i started as i had a forum that took days to get a reply from and the guy i got it all from was slow at replying.
read, read and read some more.
feel free to ask anything i can help on too, i don't want a million how to questions, but i'll help pointing you in the right direction, just never ask about closed loop idle as it's biatch to setup if the alternator is not supplying a constant 14v.

sorry should clear this up its a fiesta st150 with a 2.1 blacktop turbo (zetec conversion)

Hello guys,

I have been looking over the photo's of your inlets, but i can't see where everything goes. I can see that most of you blocked the pipe comming of the idle valve.

Now i have the next problem. I have two EFI inlets. One has the place for the idle valve and the other doesn't. Can i blank of the place for the idle valve and connect all the other stuff without any problem? Or is it better to use the other without the idle valve connection.

Was there a early EFI without idle valve? Where is the connection for?

This is the one without


This is the one with idle valve connection



Does anyone have a picture where all the hoses of a EFI inlet go? I'm building my engine up on a stand and not in a car so difficult to see at the moment


Thanks!

juffer

how do i wire in the idle control valve as in the the instructions it meantions a stepper motor??????? im using the fiesta ICV.

You are MS1 mate so I dont know?! MS2's can directly drive the Fiesta ICV's but I dont know about MS1.
Check with who built it maybe?

juffer

I have got a ms2 now from extra efi. Im in the middle of wiring it up infront of me.

Karlos G

iTrader: (4)

Oh ok!
You run one of the two ICV wires to an ignition live, and then the other one to the wire on your MS loom thats labled Idle Valve (or something like that), cant remember which way round though! lol

juffer

once again mate cheers for your help. Just what i needed.

iTrader: (2)

pretty much as Karlos said, run to pin 30 for the negative and ignition live feed to the positive.
you'll hate getting it setup right though

Karlos, I've read this thread in the past and just wanted to say thanks for taking the time to make it! should definitely be a sticky!!!!

Just been wiring my inlet with the picture of your connector in front of me

Rob,

Karlos- Nice Thread! I'm seriously considering changing to MegaSquirt in the next year or so after reading this thread....

TBH, in the past ive thought of it as a cheap and cheerful Management system that i wouldnt want on my car. But it seems i was wrong!

Its good to know there people on here who dedicate the time to talking ppl through things like this!

Karlos G

Value for money it cant be beaten and as long as you buy it from someone decent with warranty etc. you cant go wrong!

mk1trb

one with just the pipe will be off a xr3i, there iscv sit on the inner wing irrc, other will be a later fiesta xr2i/turbo one

mk1trb

can ms run with a dizzy instead of coilpack? what would be needed for that route? do you have to use efi sensors aswell?

Karlos G

iTrader: (4)

Yes it can but why would you want to? lol
Can use any sensors as you calibrate the ECU for whatever you are using.

Rob_DOHC

iTrader: (4)

I thought about using a coil so it would look 100% standard. But i've settled for the much better route of a coil pack. OEM is the only reason i can think of???

Karlos G

iTrader: (4)

Yeah I supose if you want 100% original look.

mk1trb

for the origninality factor mate, so you could use say the mfi sensors, just need to get the inlet modded to accept necassary injectors, would it still need a trigger wheel though?

Rob_DOHC

iTrader: (4)

Yes it would, and IIRC mfi sensors fit the efi manifold too lol

Its a fair bit of work keeping every thing looking original tbh, faffing around with the inlet manifold and air box.

martinmilne

karlos i already have the efi stuff so would i just need the ecu and loom that come with it and how simple is it to fit doest it come with the software to map ? and can anyone do it

Karlos G

iTrader: (4)

Yes you would just need the ECU and loom from www.extraefi.co.uk it's simple to fit if your ok with wiring but mapping is a different ball game all together mate.

martinmilne

once fitted would i be able to get it running so i could get it to someone who can map it

Karlos G

iTrader: (4)

I could email you a base map to get it running, but you would have to make sure things like your temperature sensors and TPS are calibrated etc.. all in the docs that come with MS.

martinmilne

ok mate cheers do you know wat sort of prices it would be to get mapped

Karlos G

iTrader: (4)

You will need to find a tuner that will map it and I imagine it would cost as much as any other standalone management mapping, or someone off here maybe thats close to you, if I were closer I could but your a bit of a drive.

series_one_rst

hi karlos, would you minde mailing me a copy of your base map. would be good to see your idle control settings. mine seems to not want to play and is either of or on.

thanks. ste.

as for outside companys mapping them for you, i think there are a couple places reccomended on the extra efi site. bailey motorsport near telford is one and cant remember the others. worth a look mate.

Great topic(s) on here about megasquirt. Learned quiet a lot about it. I can tell a success story. I have my own soldered megasquirt running on my cvh EFI with two coil outputs to leave the EDIS unit.

Now I need to get some last bits done to go for MOT and I can start mapping some more on the road as now its a bit shit without insurance and MOT. Base calibration needs some tweaks, but it runs a nice idle!

slimwynn

would be nice if this could be made a sticky.

Can anyone help me with a base map file for my ms2?

studabear

I might have some that could be used.
