DMS or Revo for RS4

[bobjebb]

Anyone had any experience of DMS Automotive? Or as an alternative Fontain doing a Revo upgrade?

Advice welcome and thanks in advance

Bob

I'm sure I'll get corrected, but DMS can use the Dual System (One-Click etc) and ex AmD guru Geoff Everet makes these and loads his maps on them. So, effectively you will be getting an AmD map from DMS which is pretty well proven.
But of course they could have their own maps, but you can certainly have one of Geoff's (I have spoken with him about this a while back).

Appologies if I have spelt his name wrong

Cheers

Thanks for the info - just come back from Fontain with the Revo 5hr trial. Absolutely flies from 11mph up to 23mph on the M4 in friday traffic. Awsome.

just be careful with the boost levels on the Revo remap! does it make a screeching noise when under full boost, Bob?

[bobjebb]

not that I heard.. anything I should know? Thought this trial was harmless..

This is not the first time i have heard of the above.
Could someone enlighten me as to what is going on with the REVO software in laymans terms.
Where is the screeching coming from and why?
Cheers fc

Screaching is coming from the turbos which are being worked harder and longer, the bearings dont like it.
Have a very long relationship with DMS, they modded my Mercs and Porsche with a great deal of success, merc was increased by 50 bhp without increasing the supercharger wheel which is what tuners do with them, the Porker is just silly, with 550 bhp from upgrade and exhaust. At no time do they increase the boost, just use the ignition and fueling to gain more power, so longevity are not affected.

yes highly possible, additionaly this sound could also be the wastegates clattering also - due to excessive boost levels.

there is a post about this somewhere, where Mihnea provides some explanation.


not trying to scaremonger, just that I've been in plenty of RS4's now and the only tuners code that induces this sound is the Revo code, and using the SPS3 device, you can turn the boost levels back so that this sound doesn't occur (however performance is much reduced IMHO) - proven by datalogging the boost levels.

Seriously? I didn't think that it would be possible to add more fuel without adding more air (via more boost)? Surely it would then just be running really rich.

I will be corrected though

errrh.... Lesson in engine technology coming up not to go into the physics of how an engine works, and not to blow your theory completely out of the water, but changing the amount of fuel and the timing will generate more power in certain places, and reducing the fueling in other places will also increase power, the increased fuel is not only used to increase the combustion, but also to cool the combustion allowing more timing advance, increased boost will also increase the power of the ignition stroke in the same way, but to the detrement of the engine, whereas modest changes in fuel and timing will not unless you get to the point where you are running so rich, the inducted mixture does not burn completely, introducing bore wash. To increase boost pressure, you need to add fuel to reduce the combustion temps..... shall I go on????? Not at this time on a Friday night.

Guys, do not want to upset anyone - but when I had my REVO code done at Dialynx. Geff was there the day before looking at the Revo code as he was so impressed with it. So if the DMS one-click is a 'Geff Map' one would suggest it was fairly simualr to the REVO code.

I have REVO and am very impressed, currently running Timing 5/High Boost 6 on optimax and octane booster 160K mile RS4 with no problems.

In fact - if Kev (REVO) is around I am sure he will back up the REVO side of thigs as the code was tested in an RS4 one of the REVo guys owned for a long time before it was released.

Has anyone actually got any HARD facts about turbo's dying after REVO code, bearing in mind that JR knackered his turbo's after an MTM upgarde and bushy's engine went TITS up after some work at AmD and many people have had their Turbos just Fail on them.

Not trying to get anyones back up, just interested in discussion.

Saying that though, my next amount of money on engine mods will be spent on 100 CELL cats and a Minhea custom chip ( I want to know what all the fuss is about, this man comes highly rated)

Just my 2p

High boost 6 and Timing 5 Tom ?? That seems very high to me mate...although it depends which map is in of course...I was recommended to run low boost 9 mostly...

Have you done any Vagcom logging ?

[Tomson]

Would love somoene to spend some time teaching me the ways of Vagcom.

Anyone with the knowledge around Gloucestershire ?

[sitas3]

Tom, I'm willing to show you by all means - I think it is very important to regularly log your vehicle if you're remapped..

[lengster1]

How do you know when you have got a revo set up correctley,surely there are optimum settings that are recommended?would i be right in thinking that the system is very similar to power commanders on bikes?
