Why are you considering changing is the 1st question?

VEMS is great but it's not for everyone, you have to spend time learning about the basics of a car engine and be prepared to tinker for a while until you get the right settings for your car.

I wouldn't recommend VEMS for people who are expecting to fit it and forget because it does take some time to get the car to where you want it and you have to make the effort to keep up especially as documentation is very high end where present.

Others however are happily running early releases and once car is at a level they leave it well alone not wanting the new features as their car spec will stay stable, for me your better off with motronics and a remap if this is the aim as it will be less hassle

On the flipside the reconfigurability and the running of wideband for closed loop feedback is superb and my car runs very well on it.

Hi,

In my opinion i think if you will buy VEMS V3 or 034EFi is a good product to make very hourse power.

I will buy a VEMS V3 to my 3B model.

If you can make ... buy this product.

like jamo says its not for everybody...at first.

i think we all have a similar passion here for fast cars. the ways to make them faster is based around electronic tuning.

Vems was one of the first items i bought. i have previous ecu experience though. i know in most factory units there is room for timing improvements along with fuel savings.

one thing worth noting is closed loop is best on narrowband but i wont confuse matters.

ask yourself

1. do i intend to seek more hp by changing physical parts.
2. do i have issues at present that may be resolved with standalone.
3. do i have the knowledge to tune. confidence and guidelines megamanual.com
4. do i use it as a daily driver.

go stand-alone if your answers are. 1.yes 2.yes. 3. yes. number 4 is subjective but if the answer is yes be sure its a yes to 1,2 and 3

i like the idea of it, but i'm not that geeky when it comes to computers - is it easy enough to pick up?

[GazzaG60]

its the eaiest ecu i have used and have looked at 4 types.

the software in megatune is easy. megamanual is a grewat reference.

with a good basemap your car will be running fairly well in less the 1 day. the important thing is to get good feedback so good EGT and AF gauges and logging.

to hazard a guess i spent about 5 hours in total on my car. it starts in all weather, runs fine with a few minor issues but in general smoother than motronic better on juice. idle is the hardest to get right but is getting far better.

i spent about 40 hours on a subaru with a link G3 ECu. having said that the map was pretty nice after.

I have had my troubles with VEMS, but NONE of it was because of the actual ECU or software. Its things like the USB to serial adapter and your own wiring/grounds, etc. that are the hard part.

If everything in that respect is sorted, then its super easy to pick up the software and start tuning. Also, Marc Swanson (EFI Express) has the best cust. service.

cool.. for me upgrading to a 20vt engine in the future, having to buy an ECU and then pay for a map on top is roughly the same cost as buying VEMS...

as error says im not geeky when it comes to computers, but if its easy to pick up i cant see a problem, i have few mates runnin big hp in different cars and they run different ecu`s like vems for audi. Spoke to them and they say is simple enough, but at the moment its just an option im lookin at, i think it is the way forward cheers
