Vems Vs Megasquirt pros and cons

[mushasho!]

There's only 1 choice... VEMS!

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...

Very good book, explained in human language
Learned a lot of it.

Could apply that to women also...

sorry.

so true!

[th.b.w.]

Without any more equipment like afr,intake and exhaust temp.sensors, knockcontrol unit, you blow up the Engine in a few time.

When you realy go to VEMS, you must calculate more money than the ECU.

Don,t make the mistake and think cheep !!!

Good luck, Thomas

P.S.
And buy the VEMS with good support, not the cheepest...

I started to learn from here: http://www.vemssupport.com/forum/ind...opic,97.0.html I'm not a pro, but I have at least my car running

I already wrote everything.
Less talk, more deeds - no one can decide for you.

I know, I decide to VEMS, from what I read in the forum I think is most appropriate for me as it is p & p and I'm no professional.
Thanks for the explanations and advice

Get the car mapped by someone, VEMS isn't a magic box that will self map

I'd rather do it myself, do not work in Spain Motronic s2.
VEMS is that it is not magic and that will cost me time to do it but that's what I do it myself slowly calmly

sorry.

jajaj dominated the field so much better than cars

If you want to go the route of learning by doing then go for VEMS PnP. You will find here some maps to start with. Just be carefull and work your way up. Low RPM->High RPM then Low Boost->High Boost.

That's what all of us did! If you have no time for this then let someone do it for you

Forget MS one-way or another.

Thank you very much for your reply, my idea was to start with maps "basics" and cash them myself improving little by little, I guess everyone started this way, if I have time, could spend about 10 hours per week minimum in summer limit would not have me spend the whole day with my audi.
Then I forget MS
Thanks

I'd say that it is almost impossible to map an engine (let alone optimization efficiency-wise) without any knowledge of the (gasoline powered) combustion engine. Stay off if you aren't sure of your capabilities!

First of all i would suggest to start with understanding the basics of your programmable ECU controller functions, and how they react on the engine.
Next to that try to secure your setup by means of sensoring temperatures/pressures/AFR (turbochargerspeed/knock/cylinderpressure... you know that i'm after)

Engine software calibration is a specialistic job qualification (i am lucky to have a job in that sector...)
I have respect for anyone mappping an engine on the street and keeping it in one piece (that with normal service intervals and power output )

I have knowledge of gasoline engines but especially large turbo diesel engines over 4000cc displacement, trucks, trains around a bit.
Would also have an EGT AFR future and if necessary a dyno, also count on the advice of an engineer if necessary, is not the first time I talk about engines, but if the first time I go to map an ecu, and how to learn.
I'll try to learn everything possible about the engine management, internet etc books and go slowly applying the knowledge obtained.
The accurate calibration may be left to a professional but I want to make the most of the work.
By the way I'm glad you work in a place like that

Thanks

gonzalo i think you should put your on the street first and then think about that , and is not so easy as you think and i know how you think , take it easy and put your car on the street first , make 5000 kms and you start thinking about that . its a good advice in a few years you remember me .

Jorge, the motor car is finished part is missing some things from the car mechanics, but goes up 2xxkm / h, this is a project that would carry out in one month when the car and would be walking by economic issues could not do now I prefer to leave it and report soon to do so safely.
Thank you very much for the advice see you soon friend


Thanks to everyone for the tips greetings

I'd love to work on an engine dyno someday... without the car around...
I am sure it would be a very interesting experience.

There is no book that will tell you exactly what to do.
All engines are similar to some extent - read the books, understand the theory, understand why you are doing something and then give the engine what it wants.

Could apply that to women also...

sorry.

As for switching between LPG and Gasoline, yes you can easily do this on 3B ecu, requires a little knowledge of electronics, but it's pretty much using different chips and soldering a couple of wires. Very easy.

Ostrich allows you to real-time emulate your chips on your ECU and you can easily tune your car for LPG with it. But of course the problem with Motronic is to find all the maps needed...
If you do not intend to do it on a broader scale, it is much, much easier to buy VEMS and focus on tuning your car, than try to make sense of Motronic.

I suppose all the other would like, but wondered if there was any chance that dealt by our engines, then I recommend anyone else besides those two?
I meant gas when talking about gas sorry. Conversion to LPG is not something that catches my attention and other costs seen

Motronic talked about using a turbo chip for management and one for the management of petrol and if they could make proper activation with ostrich 2.0, since as I have seen only handles 1 chip and do not know if I could handle 2 having Motronic .

Then you think I should v-ems? no better than the ostrich? that would be easier to install and adjust?
Engine is quite a bit, but I'm not profresional defend myself and I can easily learn and I like it.
