Which engine management system to use ?

[Error404]

Well I can't speak for anyone else but I was put off VEMS bevause of reliability and usability concerns. I'd rather pay more and not have glitches and have a smooth user interface. Also I can't be bothered pissing around with settings that need hours of research to understand. I just want to map the car.

Not buy thinking but buy resarching. I have opened so many OEM ECUs and seen so many pictures from the inside of aftermarket ECUS, I can not count... I've never seen something like that.

...and don't missunderstand... we still use and I still map VEMS but I know the glitches - also those, most users would'nt even notice. I logged for the VEMS guys to sort out some glitches I found and they brought out new firmware . I have done hundreds of logfiles on VEMS with different cars and now its simply time to go some parallel routes because I dont want to follow blind one route. I think I will buy also a ECUMASTER or a MAXXECU in the future cause their development looks promising. Maybe someday a syvecs. But now It's LINK time and I will share my experiences in the future when going to high boost.

Remember most users here have no time or money to spend searching as trying our aftermarket ecu's.
If you can or do this for a living your opinion bears more weight. Remember vems is not only distributed by one person or company but a lot of retailers collect the parts and put them together perhaps the ones you have seen look that.
I have had 2 vems ecu so far, both worked and work flawlessly

Glitches that blow engines up? Please explain these glitches... The way I see it, there's always constant development going on with VEMS.

only motronic , only hardcore

What makes you think that there is no hot glue inside an original ecu already? That's the way the motherboard is connected to the plug. If aftermarket ecu were always that we'll built as the motronic they would cost the same!

Since it works it's fine for me

Exactly. Maybe it's because when people started using vems it was in its infancy and the only cheap plug and play option which of course had a lot of glitches.

Those that are building race cars will invest in something worthy of that. More expensive more accurate perhaps and for a completely different purpose.

I see no reason spending 2K and above for a daily driven car. Vems has progressed so much since it was first introduced and works fine

[mushasho!]

As usual with these threads it's VEMS Vs everyone else

I find it funny because I'm not sure what the hate towards VEMS has been... I don't know of one example where the failure point of a build has been directly pointed at VEMS. Not one... That perhaps another ecu has a better GUI or more comlpete feature set, possibly, but that's personal preference.

With new Emu Black Lsu 4.9 is possible and much more.

I dont like adaptors too - but I like hot glue armageddons much less



but like prj said, it all depends on your specific goals and capabilitys. Some points for me, full race functions, CAN, on board LSU4.9 Lambda , on board EGT, on board knock control
AND reliability!!!
- fortunately I dont need a tuner

[A80Avant]

Looking at the ecu master it doesn't support 4.9lsu wideband.
Also for me I never liked the option of having an adapter for the ecu which will mean that I would have to modify the dash to fit it.
Of course this makes little sense for a race car

If you are looking for a cheaper unit - the Ecumaster EMU is very good for what it does.
More expensive - Link/Vipec.
Even more expensive - Autronic.
And by far the most expensive is Motec.

As it is possibly a race car - you need to answer questions such as Dash integration, Traction control (if allowed), E-throttle support to create proper antilag and so on. Autronic and Motec work very well together, for example the Motec dash has support for the Autronic stream protocol. So you can save a little on the ECU and if you need one of the best dashes in the world, you can easily add it later.

And most importantly - who is going to map your car? If you know who is going to be mapping it, then throw this entire thread out of the window and ask them what ECU to fit. Then fit it. This will give you the best result.

Let me put it this way - your initial question is far too vague. The answer is "the right one for the job".
If you are not planning on motorsport, maybe planning to map the car yourself then the Ecumaster ECU is cheap, works well, has great support, and is a professional product.

This got me intrigued. Still after full pricing Ecumaster costs about the same as VEMS package.

I'm interested to see what the general consensus is on the Haltech series of ECUs as they are favoured by the Mighty Car Mods boys and they seem to know what they're doing (the Haltech guys)....
