a bit off topic but has anyone on here ever heard about the rs4 having three different cam profiles?.
i have heard recently that apparently uk rs4’s came with 3 different cams depending on year, and these different cam profiles show distinct differences when tuning the TTS kits.
do your american/canadian rs4’s have different cam profiles to uk rs4’s?, could this have been SoBeRS4’s problem?.
From a manufacfuring stand point that makes no sense. I cant see them changing it 3 t8mes. If someone has etka they can look it up but I doubt it…
I don’t know the exact details of the cams but I believe doug told me that yes there are 3 different cam profiles in these engines and that the cam found in the first 3 months or so of uk cars shows a considerable airflow increase on our supercharged cars, in the region of 10 grams/sec at full chat. This why dougs old car makes very high power now with further tuning work.
11,100 with the free install at Eurocode. ;D
Doug sold it
Solid.
Perhaps I can lend some clarification. If you buy car parts from the UK as a private individual, you are not subject to the UK VAT. TTS will not charge you VAT. Currently, the the British Pound is at 0.644, hence at 9,500 GPB you are looking at $14,751. The kit weighs 84lbs and freight was roughly $350.
As a private individual, you should only pay a minimal Custom’s duty fee if you correctly code the US Custom’s declaration form. US Custom’s decided to hold and inspect my parcel and I ended up paying an $84 processing fee. Basically, you are looking at $15k delivered (I had a slightly better exchange rate).
MRC Tune: Did not work at all on my 2008 RS4, their tune is way too amped up. The best way I can describe their tune; picture you have a sound amplifier for your stereo, then turn all the nobs to +10 and try to blast the speakers. This is how my engine responded to their tune. If you watch all the MRC dyno videos, you can see how the MRC tuned cars all “puff” as the ping sensors cut the engine back . Mine did the exact same thing and the car would only perform under perfect conditions. The MRC tune kicks you in the a** at 5,500rpm+, but there is almost nothing down low.
I got super lucky and I got introduced to a phenomenal tuner through JWM here in Miami. The car is tuned exactly the way I want and none of the paramaters are deactivated (MRC tune had some of them off). The throttle response is instant and the power is linear from 2k through 8k. The JWM tune has totally transformed my car by remapping the tune from scratch. I was told they are now about to install the new twin rotrex R8 kit from TTS, should be another first here in the US.
let’s see how this goes, TTS makes some really nice hardware…
Cool
You should hit up palm Beach International raceway one night at the dragstrip. Bit of a drive but would be cool to see a tts car throw down. Get tts’ fastest rs4 title back!
shame on me for not getting to WPBIR… >:(
Sobe that’s awesome
SoBeRS4 thanks for the post, but could i ask you a few more questions?.
what do you think was the intrinsic problem with tuning your TTS rs4?-
A. MRC dont know how to tune the TTS kit properly?(this is what i feel you are inferring).
B. there is some difference with a 2008 usa spec rs4 to a uk spec rs4 that the MRC tune isnt taking into account that was causing your odd running problems?.
C. something else i cant think off, (can anyone else think of anything?).
remember there are plenty of uk and european rs4’s running the TTS kit with none off your reported problems.
i have heard danny(TTSRS4) say that his old car really started to move after 5000rpm and that maybe his only criticism off the TTS kit was low down torque, which seems to match what you are saying.
i thought this was down to the type of supercharger used(centrifugal) just getting into its stride in the higher rpm’s, where as you seem to be saying that this isn’t related to the hardware but the software used? (i.e with your now linear 2k to 8k power delivery).
any thoughts?, just with TTS cutting the price there may be some american rs4 owners considering the kit, are all americans going to have the same problems?.
similarly i am thinking of supercharging my rs4 here in the uk, the TTS kit whilst proven i always thought was a bit dear but now with there price cut looks a bit more attractive.
i could see if i could buy the aviva manifold/supercharger lump just by itself and source my own cooling system and hp fuel pumps ect, and see if MRC would tune it for me.
i also really want to see what JHM brings to the table, but could i run into the reverse problems that SoBeRS4 has encountered? some odd incompatibility issue with the software?.
if i went with the JHM kit i would want the JHM tune.
any thoughts anyone?.
If you’re UK based, I say just go to MRC and get the same kit Danny had. Judging by their responses on this forum, I’d say you’d get decent after sales support.
I’m sure the kit was designed to supply the kick at 5000 rpm. It’s a pleasure when the car screams into life at that point. Don’t get me wrong there’s low down grunt its just the grunt is more evident up top. At the new price its a no brainer, especially for you sar you’ve for all the other mods in place
The Jhm kits (they’re going to have two at least) I think will distance themselves from the others. In two ways
Power
Performance
Oh and price. So three ways.
In all three ways the Jhm kit, from what I’ve heard, will rape the other offerings
Anyone who buys today will definitely need to be a Jhm hater who would never buy jhm because if there is a chance you will, and you don’t wait, you will kick yourself in the nuts.
saki rape is a mighty strong word…
any idea on how long this wait is going to be?.
do you see any problems on the software side of things for me being in the uk?.
I don’t see any problems with software as Jhm has a server you can log in to to flash your car.
Rape is indeed a strong word lol. Not sure how much exposure you ha e to these guys but they have raped the competition in performance with just about everything they’ve touched for the 4.2 cars.
and the wait?..
dunno. they’re painstakingly slow with testing etc.
I reckon you could call them today and get a good idea of when they’d be comfortable shipping one out
They have been mentioning that they won’t be ready for go ahead on external installs (not at JHM) until they have thoroughly completed the instruction set. I believe it was like 15 pages for the B6/7 S4 kit.
Actually 43 pages of joy… 
Can i just clear something up here - we have only ever done 4 remote tunes on any cars, and the reason i never like doing it is because customers expect a map to work 100% straight away, they always think their car is perfect, and they think a foot to the floor test is ok to do without logging, so you alwys have to run less until you are happy it is ok then start changing. Its an old fasioned way that its not nice to do - even just flashing change after change is not a great way to do it.
The B7 Rs4 and R8 supercharged and turbo cars are all developed now using realtime emulators. We spend approx 2 days on each car getting them running right here. 2 tanks of fuel and 50-60 runs WOT and at load points. We use a faster logger so we can log everything on each run instead of basic vagcom logss with poor resolution.
Johns car obviously never ran right but we never had one log on his baseline tune and never made any changes to it. It never had the dual maps for throttle sensitivty in it so it could only be tested wot.
RS4s come with 3 different cams - the first 4 months of production, then most of the production and now the replacement enginess come with different cams again.
I am more than happy to show all the logs, and zeitronix logs of the cars we do to show how they run and justify the power out of them, and the times they do.
