Maybe you could explain to us why a tuned engine eats plugs poverty ?. In my 35 years of engine tuning, an engine developed to run more efficiently but "within the parameters of the stock components and retaining fuel economy " should have enhanced plug life when fitted with a higher quality plug like a Iridium of the correct heat range for the state of tune.. given that in a std state of tune an Iridium plug should last 60k miles i am surprised they are lasting a couple of k's in a mildly tuned S3, remember these plugs dont seem to be "wearing" out, they seem to be shorting out due too soot on some of the examples above.
I see you also say "MTM is known to be mild in comparison" ?? they quote 310bhp stg1 which is actually more than Revo ?
Ok chaps. this is my thinking on the misfire. I had a play around this morning with my SPS switch.
The standard settings that are fixed seem to be..
Boost 6
Timing 2
Fuel/air ratio 9
This when compared to the key equates too..
BOOST
Range 0 Valet Mode
Range 1 Stock Boost
Range 6 Performance Boost
Range 9 Aggressive Boost
TIMING
Range 0-3 91(US)/95(Euro) Octane Fuel
Range 4-6 93(US)/98(Euro) Octane Fuel
Range 7-9 Unleaded Race Fuel over 100 Octane
FUEL
Range 0 Stock Air-Fuel Ratio (AFR)
Range 9 Performance Air-Fuel Ratio (AFR)
so basically this boost=performance /setting 6
Timing retarded for 95ron/setting 2
And Performance fuel air ratio. 9
To me this seems wrong given that audi recommend 98+ ron and most of us run better than that with Shell V power.
Therefore my thinking is the timing is retarded to allow for poor fuel in the default performance mode. this would cause poor fuel burn possibly leading to sooty plugs and tail pipes and the possible misfire as the turbo spools up and fuel is not ignited at the optimum part of the stroke.
Anyway i reset mine to timing 7 which advances the ignition to cope with 99ron fuel by my calculation and there is a definite improvement in throttle response and although i only did 20 miles it didn't miss a beat even though i was trying to make it fault by booting it at low revs in the wrong gear.
Because the only way to approach these things is one step at a lime i have not looked at the plugs yet but first impressions of altering the settings are promising.
I am now running on optional setting A with
Boost 6
Timing 7
Fuel/air 8
Could it be something as simple as this ? could the stock ignition settings be a tad retarded ? causing the plugs to run too cold and soot up ?
The problem is i dont know what setting 1-9 equates too, it could be 5 degree's it could be 15 degrees on timing and for that reason i wouldnt recommend people play about to much with these setting.
It would be very interesting for someone else with a problem to get the stock timing setting turned up from 2 to 7 and see what effect it has on there problem.
Cheers Alex
My thinking is that UK V power is 99 octane....in Germany its 100 and in Ireland its just 95. given that timing range 6 is for 98 i went for 7 as i would rather be marginaily advanced than retarded given the plug sooting problems. I think the best thing to do will be to leave it on 7 for a while ( couple of days) and see if it cures the problem or by what degree it improves things and then turn it back to 6 if all is well and see how it goes then. got to be better than the stock position of 2.
Hi...it's a pity that you've had remap related problems,which seems confirmed as you've now reverted to stock,but I can say that in diagnosing the misfire on mine(related to airflow,and not the map)both Revo and AMD were extremely helpful,and went to a lot of effort and time to get to the bottom of the problem.Guys just to update you. I've had the Revo map off since Friday and since then the car has run as smooth as a babies bum!

I can understand your frustration at going to collect your car and finding it not ready,but on the other hand,seeing that both companies were doing their best to get to the problem is good.
What year is you car Alex? The younger cars seem to be componet issues where as the 2010 / 2011 cars seems software related.
Condiserding i was decent to AMD from day 1 as in my eyes it was their fault, i felt very fobbed off on Friday, and even gave them the opportunity to keep my money and place the AMD map on my car instead. When i get told after 3 hours and having my car booked in that they haven't got time, that in my opinion is very bad customer service.

I can imagine how you must be feeling, and if you get it remapped elsewhere will be intrigued to see what happens.
I have to say that after your troubles AmD turned round with that kind of a response is not what I'd expect, quite a few forum members have had good service levels from AmD.
A real shame and an unsatisfactory outcome, but at least you have your money back.
Is AmD your most local tuning house?
We have used them before and they have been great, hense the reason for going back, and it was the MD i was dealing with. Being in sales myself and if a client had a query then the i wouldn't deal with them / treat them like I was.
I'm in Maidstone so where else could I recommend?
does this mean that REVO IS RUBBISH ??
I know Awesome used to slag off REVO when they put APR on
my car but now they slag off APR.
APR was good on my previous AUQ ENGINE and they do alot more
tuning stuff.
This has been a very interesting thread for me.
I'm looking to have my car remapped and I've got to say, the urge to completely write off Revo straight away was there, but I thought I'd do a bit of homework first.
First of all, I'm looking to have my car remapped by Audi, because then I'm completely care free when it comes to warranty. I did this with my old car and it was done at the dealer itself. This time I got told to go to the remapper themselves. In this case, Richter Sport. They use ABT maps. With that, I then asked him if I can go to any of the remap companies and he said yes, but he can only recommend Richer Sport because they are 'Audi Approved' tuners. So ABT are Audi approved so you will be covered under warranty if you use them. After I chatted to him a bit more, it turns out that ABT are having problems mapping DSG S3's (which mine is). Apparently they cant get it solved yet and have gone as far as taking the remap off some S3's and put them back to stock because they just cant solve the problem yet. So for me, ABT are out.
Then I got on the phone to Statller. I got told pretty much the same thing by them. They said that Audi have encripted their ECU's and it's not as straight forward as plugging in a machine to map the car. They have to physically take out the ECU and do it the hard way. They also said that a GIAC map won't suit the S3 at all because they just haven't cracked it for the new ones. But they have had problems with hesitation also with other maps they use. I also got told that with the s-tronic, you wont get you're moneys worth because the gearbox limits the power of the engine so you wont see the full capabilities of the map. Baring in mind too that if they have to take the ECU out, that's an extra cost on top of the remap cost itself.
So next in line was Backdraft (Revo), and I got the impression that the guy on the other end either didnt know what he was talking about, or he wasn't being open about problems that they've had. Lost of hesitations over the phone when I was asking him loads of questions about the gearbox limiting power/hesitation problems. Quite apart from the fact the newest S3 he had mapped was a 2010 model. So I'll probably ring their HQ and see what they say.
Then I got on the phone with Qs Tuning, they said that they don't have to take the ECU out, and that they can get by the encriptions, and that they've not had a problem with any of their maps on the S3. Also no problems with gearbox allowing you to use the full power and a quoted figure of 310bhp. I know that they are more expensive at £699 + vat, but when you take into account that the others want more for taking the ECU out + any potential problems, I think it makes them worth considering. Also MTM is used by some Audi dealers, so the possibility with full warranty is there. I just need to check and make sure with my dealer that they'll accept them, even though they don't use them themselves.
So now I'm still waiting to hear back from AMD and I'll be giving them the 3rd degree as well. I think my 2 options as things stand at the mo are MTM or AMD (depending on what they say). We'll see...
Have you not thought about a Shark Peformance remap? I haven't heard a single derogatory thing about them. That's who I'm planning on getting mine mapped with when the S3 arrives.
Interesting post above, ^^^, and certainly I am afriad been mis led a little.
No Audi dealer carry out tuning under Audi GB., I have heard of a Audi garage being a tuning specialist, but separate to the Audi part. or do they recommend anyone, and if Audi HQ find out the warranty would almost be void on their discretion, Dealer level is purely on the dealers discretion UN-officially of course. My Opinion is take it for granted that AUDI GB have a 100% case to refuse warranty work if they know that a car has been remapped.
My Latest update, I have had the plugs replaced today, and that has solved the misfire. The V10 Revo software upgrade I am almost 99.9% sure it has solved the slight hesitation i have had ever since Revo was put on to my car. I feel so far that V10 is not as aggressive as 9, but it is early days and need the ECU to settle down. I will wait for say 500 miles and then switch off the software via the switch and see how it drives with software stock mode.
NOW this is the worrying part, and it is my opinion so far based my own evidence, reading other peoples opinions, I am not 100% sure my very slight hesitation that I reported on here as soon as the Revo software was installed was on the car before the install, but one thing I do know for sure is that in stock mode after the software was installed the hesitation was still there just a lot more subtle, but it was there. a few people who drove my car agreed it was there, though most cases they admitted unless I told them and showed them they would not notice it. Now, If I return my car to stock that hesitation should return as Revo maintain that the initial hesitation is a problem with the car, and I had to agree at the time, on information that stock meant that no revo mods were effecting the ECU, I now in my view disagree, I am pretty certain that this hesitation was caused by Revo, and it also caused the hesitation in stock mode as well.
Thoughts please.
Lets see how long these plugs last?
Just another note, If I was to Choose any remaping on my S3 now, I would have gone to MTM, it is in my view the closest worked with Audi tuning I think, it may cost a lot more, but it would have been a bargain for me compared to the costs I have paid out with Revo related problems.
Personally i dont think the figures matter, its more a case of if you are happy then who cares if its 320bhp or 620bhp.
Funnily enough I switched from MTM to Revo when it was £1000. I ran MTM for a month and it just didn't float my boat. No way on this earth mine was anything over 300bhp from driving it. What other mods do you have for 322bhp?
