once conversion is done I don't plan to be changing spec, money isn't a major factor but I just can't decide which route to take, but defo need to start finding all the required parts

Pro's and cons for both or general opinions please

 

MS has lots more features, brand new loom and ECU, but less tuners map it, Cossie has far less features, 15year old looms and ECU's, but every man and his dog can map it! lol

 

as above, i'm an MS'er, i think it's a great thing, i've learnt so much about how an engine behaves with it.
what do you want to know, ms can fuel and spark properly, full wideband controlled adjustments if you want, so varying fuel would be no problem, launch control/anti-lag, boost control, nitrous control, shift lights, full stepper motor control if you wish.
i'm sure there is more, give me time to think

 

how much is megasquirt? where is the best place to buy it from?

 

Buy from www.extraefi.co.uk

See my thread here for full details......
https://passionford.com/forum/ford-e...quirt-efi.html

 

how much and where depends on who/what you know.
i paid Ł320 for my ecu an dpart loom running wasted spark, so no edis, just a coil pack.
you have to make a loom from a frst/2i/3i/zetec engine loom, then you need to start mapping and get the startup settings right, this is the hardest part IMO.
you can go to M-tech, although i've heard mixed opinions.
i got it off a guy on xrtwo.com forum called 'steve'.
they'll probably cost more due to the drop in the pound over the last year.
you can get a lesser version, but the MSIIv3.0 is the best and can run on extra mode, so 16*16 fuel tables, much more precise control of fuelling then.
lesser models can be bought for around Ł200, slower processor though.
ideally you need to get a wideband afr setup too, innovate do one for less than Ł200, then you can map it whenever you want after any changes, such as cam,turbo, injectors etc.

edited: efiextra.com is where i would recommend an ecu etc.

 

im on cossie managment and although people are saying its old, it doesnt matter you can get a brand new loom made by ryan (think thats what hes called) as youve said money is no object, anyone will tune it who can specialise in cossies and jano is a top bloke and will give you as much help and info about converting and can supply all parts ready!

i was going to do EFI conversion but you dont get much gain and its harder to map, so i was lead to believe and i never even looked at megasquirt seen people on here having issues with it though so i stayed well clear.

 

If your on Cossie mate then you are EFI, and have gained plenty

 

More people can map MS than L8!

FAR more in fact!

Me for example, lol


Mtech is a good option for a well built MS unit, although its branded as their own in house and has some slight upgrades to it over a regular MS.

 

-Both do the job of fuelling and ignition fine
-Megasquirt can do COP/wastedspark more easily
-Megasquirt also has autotune
-Megasquirt has full support for a wideband, this is a BIG minus for Cossie
-It is easier to hook up things like rad fans, water injection, etc. to the Megasquirt.
-Cossie is fully sequential as standard, MS (MS2 only) only with upgraded firmware.
-Cossie is ok if you tune it once, then just drive for years.
-MS works right away with either the RST distributor or the cvh-efi flywheel triggering, Cossie always needs its own dual-trigger scheme. Doing this DIY can be unreliable.
-MS is so easy when you want to change a setting, like the temperature where fans kick in, literally a one minute job.
-MS has the ability for anyone to record datalogs and there are software to analyze them later.
-MS is only an option for people who are able to search for and follow instructions and don't expect a plug and play install.
-After the MS is installed and set-up, it's at least just as reliable to drive and forget.
-If killed, the MS can be easily repaired by anyone for a fiver. As all the repair instructions, schematic drawings and test sequencies are available.


Happy choosing.

 

some good points on both sidesn there

 

ive a cheap l6 and 2wd loom going fo sale in the rst and cos parts for sale mate ,

 

Thats right, MS should. But in my experiance 8 out of 10 cars i have seen never run right or have some issues that the installer or maper has not been able to sort out. This doesnt mean it cant run right, as obviously it can. Your in finland (It says) so availibility of tuners for weber may be harder for you to find, hence why you chose MS. Where i am there is 5 good tuners with respected names that can map any of my cars for around Ł100-150.
Why is it more easy? All you need for a L6 which costs Ł50 is a coilpack driver which is Ł100. The L6 variant costs Ł1600 new which you can still buy direct from the manufactor. The weber setup is what most after market systems are based on anyway and other systems use the same sensors anyway like Pectel, Omex, autronic etc etc..
Great? So why it cars running MS still dont run 100%
This is another easy upgrade for a weber ECU using MSD chip. I would rather a decent name like MSD controling my closed loop lambda than a home made ECU..
Rad fans? Why involve fans to the management system when most cars that we would fit management systems to already have a great fan control system.

As for water injection pin12 from a weber ECU is the earth trigger for Wi. So all you need to do is set the ACT + the BOOST level for it to come on at, then if the pressure drop below x amount or ACT drops below X amount it switches off. Simple.
So out of intrest how much is the MS2 ECU that has been professionaly built and convered to stop dust and issues etc..
As said sequential injection is std on all weber ECU's which is far better than a batch firing system which is why even the best and fastest etc etc.. RST all use sequential cam sensor and cps setups.
Thats exactly the point. Why would you want to touch it once its 100%
My advise would be dont DIY important CPS and Cam sensors. Just spend Ł100 with a well know company to supply a 100% setup. For any system!!!
As said above the FORD fan control system on early cars are fine as long as you use the correct fan switch thermostat and liquid.
This is a nice feature available on most newer systems however if the car is setup and running 100% why would you want to be datalogin and messing around with the system. If you want to mess about then again MSD supply a fully mapable system for the Weber ECU that datalogs and adjust's etc. Why the "normal" person would want to do this is another question.
But above you said its autotune which is a bit mis-leading.
Any system from MS, Cossie, Pectel, etc etc.. would be reliable to drive and forget as long as its been done right using the correct parts.
By anyone? I doubt. For a fiver.. just makes me like the ECU less meaning it only has a fivers worth of parts in it..

 

I'm sorry if I offended you in some way with a subjective view.

 

O.K.C. you're talking shite lol!
MS is very capable, it's the suppliers and fitters that are crap.
mine has been absolutley fine, with me being the only fault.
somewhere like M-tech would now make it, fit it and map it, or so they claim at least.
of course cossie management has everyone mapping it, it's been around 20 years or so.
you can't say Megasquirt is worse, it can be better.

if you're not confident with DIY, then go for something off the shelf.

 

Megasquirt do a PNP model now and they have just released a DIY PNP take a look.

www.DIYAutoTune.com

Ok so there's only three types of auto plug at the moment but they say there will be more and all your have to do is plug it into your existing loom.

Should be really good then they do the Ford plug.

Ferd

 

We're about to launch a Ford PnP V4 ECU, should make all of this alot easier.

We fit and map our V4 for Ł995+VAT, thats a 'trailer in' drive away solution...

 

OKC makes some good points, the point of closed loop being the be all and end all as told by some is crap, I notice ZERO difference when mine is enabled, but it is mapped right, CL is just unnecessary imo if mapping is right.
tabetha

 

I've chose weber marelli after speaking with jano at ford fair and national day

 

makes good sense mate. i'm going weber on mine with a p8 and all the toys
