Hello, not 100% sure had it looked at they said some thing could have gone throught from the turbo what ever it is they said it aint good. It's a knoking/rattling noise from both the turbo and bottom end.
liam.

Please move that off topic to a topic of its own.

Here in Slovenia plenty of cars runing megasquirt.One of them is also 3B S2, it runs 12.7 with stock turbo.Fastest MS car here is nissan nx100 his best ET is 11.95

Yeah, I'm wondering why the bad vibes on the MS from people. Have they used it and had bad experience? Seems to be a lot of people who are running this with no problems?

[Jensk]

Maybe the problem with MS's reputation is that since it is so affordable, people who shouldn't be messing around with standalone EFI's is. And blows their engines etc.
I can't see any reason for MS not to be as good a choice as any other, but if you require lunch control, water injection and such you have to modify it.

Support is maybe one of the downsides. As its "free", it doesn't come with a full manual and warranty that an Autronic og Haltech unit would. There is a manual on the internet, but some knowledge of electronics and computers would be of great use.

The tuning software used is MegaTune. Its actually not that bad. I liked it more then i did both Haltech and Autronics. VEMS also uses it. Again, Megatune is free.

.

There's no need to modify it.It normaly supports NOS options, lunch control, water injection etc..There's is no need to use MAF.It has his own MAP sensor, you can choose between, 2, 2.5, 3 bar map sensor.

The software does. but you need to run MSnS (megasquirt and spark) and you need some additional electronics too for it do work. Take a look at this page

One case with megasquirt, 2ms dwell was set in megatune but what it actually gave was anything between 12-18ms. Fried 1.8T coils after 60km drive.

You simply cannot compare MS to any other of the standalone brands mentioned in this thread. MS is budget system for budget projects.

Let me see a megasquirt-equipped 11 sec daily driver, and prove me wrong.

I have tuned more than 10 different brands of standalones, and I must say that although the tuning with megatune is easy, and software itself is very visual, the system just does not have all the compensation maps You need to get MAP-controlled motor to work in daily use.

And by working I mean that motor does not cough or hesitate or nod or do anything else but run smooth.

Here I'd like to quote a friend of mine:

"getting power is no problem, getting it drivable is"

This is called second Makke's law.

Also, for those who dream of swapping MS to Your Audis. I have done that. Twice. By experience of installing more than twenty standalones prior to those. Took me four days from first start-tryout to get the first one running. Had probs with interference, bad solders, insufficient spark, bad ecu connector, wrong type components... All the probs in the book You'd never face with "real" standalone.

After we got them running, they cannot handle high boost, as the spark is too weak. You need to tweak the dizzy to get the pointer to point the contacts of the plug cables and play with spark plug cap clearance. And still I doubt, You get serious performance, as the dizzy-system just is too weak for high power.

By the experience of tuning cars for 6 years as a professional I can say I will not touch a MS again. And I certainly recommend people to stay away from them, unless it is really a budget project, which S2's rarely are.

3B S2, it runs 12.7 with stock turbo

Yea right.

Downhill dragstrip maybe? Terminal velocity tryout?

MS is pants, had it on my old ovlov never again!

It's a cheap american lego set

The VEMS system also uses megatune, tough obviously with another config file. Have you got any experience with that system? I'm wondering, because I'm thinking of sticking it in my UrS4 (as long as i don't have to go back to using a distributor that is). But if you think it lacks features critical for the system to be a "safe" daily driver then it might not be such a good idea.
I don't know if VEMS is a completely new designed EFI or if it is some sort of MS clone.
But there is a guy (http://www.brillko.se) in sweden using it in a high sevens(7,56@291km/h) car. Should indicate that its not TOTAL crap atleast

Anyone else heard of KMS?

[kalsket]

I'm currently running VEMS in my RS2. Only thing it has to do with MS in MegaTune software, nothing else.

It is possible to use vems with original triggers, COPs (or dizzy), sensors etc.

Biggest problem at the moment is that over 6000 rpm there are trigger errors. New firmware to get rid of that problem is coming....

I don't know if KMS has five ignition drivers, but it has only one injector driver, which automatically means that it's not good for Audi. Or You need milliongallonperminute fuel pump.

Also tuning KMS is pain.
