Aftermarket VS motronic management

[Jamo]

If you believe that I need to prove anything to anyone, then you are grossly mistaken.

Well no you are mistaken because you are trying to sell a product, how can you sell a product without proof?

If you don't want to prove anything thats fair enough but then do not rubbish others tuners work for being dangerous or silly!

Popcorn anyone?

I'll take butter on mine

Vas is going to be in for a nice surprise when he looks at his thread in the morning

Great statement from someone who does not understand.
Yeah, let's turn off fuel cut, boost cut and map 200 hp of the engine to the last cell.
Lower the entire fuel map instead of telling the ECU the size of the injectors, etc.

Sure, that's nice tuning.

And I go back to your supremist attitude, you have no idea of what I do and don't understand, I'll take a leaf out of your book

I've said my bit end of the day

sorry folks no more popcorn

sigh, I wish Mihnea still came on here

On a calibrated temperature measurement system I use for work it got down to -21.2 here on our coldest day. My Audi on vems started first crank.

But it does idle slightly better on motronic.

But vems doesn't eat maf sensors

I can tweek my own vems

I have to pay and travel for motronic adjustments

Vems Is happy to work with wideband so I can run lean burn on lpg.

Both had great boost control.

So I prefer vems, but motronic is great too, just not as fine tuneable.

For what?
There's not enough financial reason to develop anything for ancient 2.2T. That's why he quit long ago.
You guys crap on anyone who still does anything anyway.

But vems doesn't eat maf sensors

Neither does Motronic with a HFM5.

Vems Is happy to work with wideband so I can run lean burn on lpg.

And why can't Motronic run lean burn? I have been running lean burn - 16 AFR cruise for half a year now.

but motronic is great too, just not as fine tuneable.

Correction - you do not know how to tune it. Every single aspect of the damn ECU is mappable. The only thing there is, is that it won't run on anything other than 5 cylinders, because the code is custom crafted to it.

[Billman]

Lets get back to the topic. I still have my original Motronic and i intend to use it on a SQ replica someday. I can run it either on the chipped RS2 setup or something else. If you develop the daughterboard and i can tune it myself cheap then i will use it. If not and i want more than a couple of chipsets i have then i go there to VEMS also.

[A80Avant]

Dmitri, you do know that VEMS provides all of the above, (fuel cuts, boost reduction above EGT set level, Fuel addition above EGT level, etc. So at the moment i cannot see motronic being better than VEMS in those areas.Cold start is not an issue either and as Jamo said, if i am not going to be living in the Freezer, i dont really care if the car starts at -35.And even if it is -35 outside, am i going to take my more than 30K euros car outside for a spin, in the snow and freeze? probably not. So extreme enviroments make all ECUs a bit twitchy and it will not be a turn down for any potential buyer.

Up until you entered the tuners' scene, i must say all owners had a few well respected names around that could trust would build them a proper tune on motronic. We asked no real questions, we payed the price and got our smile on the face, until possible problems appear and then the tuners dissappeared!!! (at least that was my experience)

People that have had similar experience to that would possibly want to tune on their own anyway, or at least get involved. If i were to pay you to do a tune for me, i would like to have the possibility to understand motronic to the extent that i would be able to handle a few things on my own once you left. If that meant that i would need to spend some money on equipment, i dont care, cause once you go back to the country, i cannot have your help anymore, and i cannot wait with the car in the garage until you have a look at settings.

That is the same with ANY aftermarket ECU that you will get a tuner to tune it for you and you dont get involved. So motec,haltec,Vipec, Nira, etc. All will have the same downside.

We are talking more about vems because its an open community, people shared and a few that wanted to get involved and interested, do it. Sure it takes Billman, Jamo and myself longer to fine tune everyting than a proper educated tuner in these matters. But that is our choice.

My suggestion would be that anyone wanting to run a modified car to some extent( not a Lambo he just bought and chipped), needs to be aware of some mapping stuff. Most UK hobbists do a lot of stuff to their cars on their own, and this aspect is left out, whereas im 95% ilitterate in mechanical jobs (Rob will confirm!!!) but i did some studing in the mapping department. I am not a tuner in anyway, but if Mihnea or Dmitri give me a few hints of translation of values in motronic, ill understand much more than what i would 3 years ago.

Question is, are motronic users willing to share? (Ancient question....!)
