Iv got a S2 ZVH and I am trying to find what management people would rcommend and wher to buy from. Short and sweet, any help much appriciated. Cheers

 

What's your budget?

 

Not sure yet as im just after a rough idea what people would recommend then go from their really.

 

There is a gotech ecu and mos parts for the efi conversion in the rs turbo for sale section,400 quid the lot

 

Iv already got the EFI stuff just after the loom and ecu, but will have a look

 

choose your mapper then fit what ever system they want to work with.

 

As Crazycage said go to who ever is going to map your car and fit what they like mapping.

 

+2!
We do when it can save people literally Ł1000's of pounds and a year of ball ache!!
Fucking bell ends!! lol

 

Jamsport are pretty close to u,around 75 miles

 

jano.

cossie managment.

 

You will not beat a properly mapped megasquirt even at many times its price.

 

Sorry but how can you put a commen like that above?
Have you any proof of this?

 

Who can map megasquirt tuner wise?
Isn't it a DIY system?
Does it have any downfalls over say gotech or autronic?

 

Pm Karlos G,he's successfully mapped megasquirt,and i havnt heard of any horror stories with his mapping..........

 

What do you mean, proof of what? lol
It's standalone management just like any other and is as good or as bad as the mapper.
There are a few of us on here that can map it, myself and Rick included but not many of the big tuners choose to map it (they could but they dont), mainly down to problems that can arise from poor DIY assembly/installation.
It can be baught DIY and assembled yourself but much easier to buy a prebuilt one.
No downfalls what so ever, can do everything that any other management can do and is far cheaper.

 

Oh ok... So where would i go to buy a pre assembled ecu & loom for an EFi Fiesta RS engine?

 

www.extraefi.co.uk is where I buy all my MS ECU's from, list price for a MS2 ECU and loom is Ł370.

 

Proof is a strong word, but I will attempt to justify my commen(t).

I work as an instrumentation engineer for a multi billion pound company where I put systems together as for measuring and calculating flow, level, pressure and temperature. I have a first class honours degree in Electrical and Electronic engineering. As part of this, my thesis was on engine management.

I have built and mapped many engines in my spare time, on various aftermarket management systems. I also understand and can map - from scratch - certain modern OEM ECUs like Bosch Motronic which are several orders of magnitude more complicated than the most sophisticated aftermarket ECU.

I have no commercial interest in any system so my views are purely objective, based on experience and education.

It's my opinion that Megasquirt can't easily be beaten by other systems unless you have specific requirements such as fly by wire.

FPMSL! well said that man!

 

Hello Rick,

I would not compare MS2 to Ford EECV or many modern factory ecu's.
MS2 is fantastic for the pricing - but in standard form does not even provide for
fully sequential fuel injection. It is a batch fire arrangement.
MS3 has come a long way, but still not close to some factory EMS.
However, factory management systems are not all that easy to map - unless on has the
correct tools. Same goes with the Cosworth management. I have programmed the old Cosworth ecu's - a bit of understanding required as they use hexadecimal (00-FF) for mapping values.
For the self mapper (like Karlos) the MS systems are fantastic. Low cost and relatively easy to map. The mapping software is quite user friendly.


These were used for many racing engines in the late 80's (I am aging myself )

 

Perry,

may I draw your attention to this from the post above:

With regards to sequential, it may only have two injector drivers as std, but the software support is there. One of the first things i did on my old CVH was put in Jean's peak and hold 4 channel injector board. Very easy add on and you now have 4 channel seq.

However, i have never needed it on the engines I've mapped. The control over large injectors is superb - std CVH's on grey's that cruise at 1.1 and idle where ever you want them, with excellent response. There is the potential for more economy and off idle response with seq but most people wouldn't notice it.

Hi Rick,

I am not trying to argue with you. I agree that many factory ecu's are very sophisticated and impressive. However, you cannot say that these "factory ecu's are several orders of magnitude more complicated than the most sophisticated aftermarket ecu."
This is just not a valid statement. The Pectel SQ6M12, and Motec M880 are just 2 examples. These are aftermarket ecu's that professional race teams use. Costly yes, but certainly a step up from the Bosach Motronic system.

 

You guys have lost me...
What does "cruise at 1.1" mean please?

Karlo's - Is that Ł370 MS2 ECU & Loom pretty easy to wire into the existing sensors etc?

 

Relating to the original post: Figure out your budget, find a tuner, and then figure out what is best for you.

Cheers

 

its the fuel ratio

 

Oh ic.. should it be a 1:1 ratio?

 

Yes mate just chop your old connectors off and solder them onto the new loom, really easy!
1.1 is as said the fuelling in Lamda.

 

Oh sweet... Maybe MS2 might be a wise move in the future then... How easy is it to map? Is it literally like you see the pro's doing with a laptop on the move, adjusting fuel tables and spark advance etc etc?

Oh ic now, 1.1 in lambda!

 

Yup exactly like that! Takes some skill and a good understanding of what your try to do though.

 

Wicked, better add that to the ever growing list eh?
I know you managed to convert Jonnie from OFAC to MS2, so maybe i'll hitch a ride in his sometime and then go for it!

 

Im after a few suggestions so i can find out whats best for me, i was really just after a rough idea of what everyone else uses and what the pros and cons are before i go and commit to buying.

 

Lambda 1.1 is quite lean.

I like Omex for simplicity and ease of use.

 

whats your afr on cruise ?

 

I'm still on a CVH with big heavy valves that don't like heat so it's between lambda 0.98 and lambda 1 on cruise.

 

i know you are that why i asked . the afr's mentioned are not from my zetec, there from richies 300+ hp cvh that rick mapped.

 

I'd certainly have no problem running a Zetec at leaner than lambda 1 on cruise.

 

1.1 runs cooler than 1.

And at steady 70mph there isn't a lot of heat anyway. Soon as you tip in, that's when the fuel should come in.

Rick

 

been out in it today and sitting at 70 with afr reading 15.8 egt was around the 650 mark with engine temps mid 80's so possible to cruise at a lot more than lambda

 

Rick, not on my car it's not. About 50 to 80 degrees warmer. My engine doesn't like running leaner than stoich. It starts to struggle.

 

Thats very interesting!
Mine is the same, anything leaner than about 14.3 and it starts to hold back/struggle.

Wonder why Richies will happily cruise so lean?
