Vems Vs Megasquirt pros and cons

[lakeone92]

Hi guys
Looking for an engine management system alternative for my car (s2 3b)
I'm pretty new in terms of electronics but I have plenty of time to try things and eager to learn, first look for something that is P & P is that you start easily or not cost much.
I've seen these two options between which there is a big price difference.
The first is known Vems great forum. http://shop.vems.hu/catalog/vems-motronic55-p-122.html

The second MS is very popular on other sites but this seems stranger than it costs half http://www.diyautotune.com/catalog/d...kit-p-385.html

Are equal to the Vems, and MS? to the naked eye are the two 55-pin Motronic and appear to be suitable for our engines. which you recommend me in terms of simplicity of use and ease of assembly?

That would need to start my car with one system or another?

A greeting and thanks

Don't think Microsquirt will work... unless you keep the distributor, but that'd be defeating the purpose.
If you want a true plug and play setup, then get the PnP version of VEMS.

And please define what means "will not cost much"?
A programmable ECU will cost much, it is normal. Besides installing it, you need to tune it (or get it tuned) as well.
So it will cost lots of time and/or money.

Then again, if you need the programmable ECU, chances are your car has already a very powerful setup, and in that case the costs of tuning and installation (~1500 EUR) might be "not much" for you.

Could you tell us more about the car where you want to use this control unit?

Any way i look at it, 1500 EUR (~$2200) is a lot of money.

Lakeone is looking for something between 400/800€ ...for tune everything himself

Vems seems to be the cheapest solution maybe

and be careful,because tune it by yourself it is not easy as you think

Regardless of engine management, you need to understand very well how a FI engine works if you want to tune it yourself.
A standalone ECU is a great way to learn - of course the question is, is it worth risking damage to your expensive engine?

Because it would be counterproductive to keep the distributor? I could not get out of the hall sensor signal and make ignition coils?

What I seek is essentially the "plug"and start without much difficulty.

From us about what the "Will Not cost much" I mean that I would not like that cost me much money, have much time.

My car is a s2 3b and this stock, I want the programmable ECU to take advantage of the mechanics of series to 100% and to get the most out of every little mod that will make the car to end up having a big machine made and programmed by myself.

1500€ is a lot of money for me right now I can not assume that spending (I'ma student)

1500€ I see it very expensive, I guess that can be done cheaper using more time and I have much time

I told you what he wanted, which is almost plug & play and cheap, I do not mind being a long time adjusting because I like the track and I have a desire to learn we walk in plenty of time I can use it

I'd do it all slowly learning, because most low and well worth that much and bad.
I like to learn and eventually know how to handle a 100% programmable ecu and I think if I do it with some means such as wideband, EGT, careful not do crazy things with a sense not run a high risk



Greetings to all and thank you very much

The only plug and play solution would be VEMS, which costs about 950 EUR, this is not counting tuning.
On a stock car for 950 EUR you can do a lot more - get it chipped for example...

If your objective is to learn how to tune cars for cheap, get some old car with a carburettor and a book. Play with ignition advance, AFR, etc..
Or if you have a lot of time, you could always get an Ostrich 2.0 emulator for 175$ and start playing with Motronic. There is enough info out there to find fuel/ignition maps and limiters...

950 eur is an affordable cost for me expensive but I guess I think it will be worth spending the money 950euros although many things can make my stock car, turbo injectors etc, I prefer expended in a programmable ecu and go slowly learning and in the future to make my maps for my mods poprios.

It is very difficult to me with warranties chipped in Spain, I do it myself, since I have a long long time and go slowly learning.

I like the idea of ostrich 2.0 Tell me more about this option please, but I would like to control fuel, ignition, turbo pressure etc etc could do with ostrich 2.0?

Hi,

I'm running VEMS since two years and i can say that it isn't easy to tune by yourself!
I spend a Lot of time, but when i was at PKM i can see that this
man understand his job!

When you will cheep tuning than let your Motronic work, don't think
an VEMS or MgSq are cheep!
The only cheep thing is the ECU !!!

The main thing I want is to be not very expensive, approximately 950eur maximum. I have the stock unit to move while learning to drive the programmable ecu and I would like to learn to do, I want something to start easy and get better myself and learn little by little, time does not matter to me (I'ma student) and I really like the subject, I have also wanted to learn. I just ask something that is not too difficult to start, from there I would do it little by little.

Thanks

You should start with this:


This would do you good as well:


Before you start playing with your engine it is a good idea to read a few books.
These are two decent books that will show you the basics...

[Rocco]

Gonzalo,you have to start firstly your car

my car is "finished" and walks, runs and others but is an S2, do not expect no problems

As I said - if you have no experience calibrating an engine, you should start with *learning* and then applying that learned theory into practice.
It's pretty easy to blow things up when you do not have any safeguards.

Take very good note of what this man said.

Very interesting! any recommendations more about books? Especially one that addresses the 2.2 turbo audi or similar?

I would like to apply the theory gradually practice, start with something simple like ostrich 2.0 I do not know if you can use in our ecu chip to carry two "turbo" and "gas. "
Doing so consistently and quietly without working beyond my means need not pose a risk, I do not want a drag car in the car not the day.

I know that the only thing cheap is the unit but keeping it and would have a base and go about doing things little by little, I think as a long term project slowly with small upgrades each time

Greetings guys
