Has anyone installed a REVO ECU on the RS4. i have heard it is amazing and a must have to help the throttle response and make the flywheel feel lighter????????????

No flywheel lightness was felt. If anything it felt like it lost some bottom end. I reflashed back to factory w/in a few days and am happy again.

I will not name the source, but someone did dyno an RS4 w/ Revo software, it lost torque and gained less than 10 hp at the top end. Not worth losing warranty for nothing.

Obviously, there is a reason that Revo will not give us any accurate dyno results for their product, the gains are crap and I'm sure they know it. Revo, are you reading this? Bummer, eh...

we tuned my car at kmd on there dyno and the results were great (i will ask danny to email me a copy of the plots to post up here). the settings on the flash are very very sensitive so a dyno in my opinion is crucial for the flash to work efficiently it really is all in the fine tuning. i did several dyno sessions to get it just right and sometimes it felt like a dog down low but believe me once its tweaked PROPERLY the suggested claims r there. my buddy with a stock rs4 cant beat me no matter how hard he tries in any gear. im not trien to start anything on the forum but dynos dont lie(at least i dont think they do). i welcome anyone to try it out on mine :P

ps... i have zero affiliation with revo for what its worth

Firstly, where have you heard that it is "amazing" and a "must have". No amount of software tuning on this already near-max tuned normally aspirasted motor is going to be amazing.

Secondly, you don't want more throttle response than is already present on this car. As it is, it is twitchy enough to drive slowly. Do you want to make it impossible to drive under "normal" driving conditions?

Thirdly, the only thing that will make a flywheel feel lighter is a lighter flywheel. Imagine that. And a lighter flywheel is not necessarily a desireable thing. It will allow an engine to rev down just as quickly as it revs up making driving very choppy. This engine is rev-happy enough.

Honestly....leave this motor alone. It is damn near perfect. If you mess with it, you will lose out somewhere.

KMD should be forwarding those graphs shortly. In general, our claims of power increases are based on what we've seen while tuning. Overall, the gains are relatively modest but considering the RS4's pedigree, that is really no surprise. In fact, our marketing is focused more on the positive change in 'feel' and drivability as it's these changes that, anecdotally, seem to be touted over and above the more pragmatic changes in performance. Of course this type of feedback is very subjective but I can honestly say, of all the comments we have received to date, both from dealers and customers, no one has been disappointed with their purchase.

I have never driven a Revo tuned RS4. I have no doubt that the subtle tuning differences can nicely tweak the feel of the motor. That's fine, as long as people accept that is what it is. Subjective driving impression is very important and this is what should be emphasized. That's the same reason many of us prefer the RS4 to the faster stage 3 B5 S4, for instance. Looking forward to having the opportunity to drive one. Too bad Revo won't be coming to the Northeast Spring Bash. I did send an invite but no response back. Same for KMD. Two e-mails....no response back.

You won't make 30hp on this motor with tuning. What you will do, is make the throttle feel so much better, remove the soft rev limit up top, remove the speed limiter, and get an honest to goodness 10-15ft/lb down low.

It does take a bit of time on the street to dial the software in, as these motors are VERY sensitive to ignition timing and fuel quality.

Nobody is forcing this flash on you, but I assure you the difference between a stock car and a tuned one is night and day :)

Please forward me some information on this Spring Bash...

Thanks!

"Honestly....leave this motor alone. It is damn near perfect."

Honestly............If you leave this motor alone the guy that doesn't will smoke you. Leaving you with the feeling I got to do something with this motor. RS4 will never be impossible to drive under "normal" driving conditions.... unless you suck at driving.
Be a MAN Mod it!!!!! Girly man dont mod it and just buy RS4 cocktail glasses,RS4 golf umbrella, RS4 polo shirt.

With all due respect, if all the REVO will do is improve "feel" then I find it hard to believe that a car that is flashed will "smoke" a car that is not flashed. The difference between "feel" can easily be made up with driving ability. I've embarrased some far more powerful vehicles on the road by making the right dowshift at the right time, for example...

Significant improvements must be proven to make it worth while...

ovbiously this is not a turbo car so gains are always gunna be modest. but it imrpoves alot more than just feel and with the downpipes makes the car feel complete its almost hard to explain and by no means is the car "harder" to drive

did my tuning on the street w/ an authorized dealer in my area with dismal results. Set the timing for 93 octane, which I run either 93 or 100 VP racing fuel. I'd be willing to try it again if you can promise some torque gains...

the three settings(timing fuel and...something else i forget at the moment) are based on a scale of 0-9 i believe and just having it set 1 too low or 1 too high will change performance dramatically and EVERY car is different weather factors are different so dynos r very important(in my opinion)... not for overall numbers but more to make sure ur getting the most out of the flash.

I have to say that there was a substantial gain I'm whp/tq #s.. I'm impressed with the performance gains of the revo flash.. Stay tuned!

"Significant improvements must be proven to make it worth while..."

Rs4 is very well tuned."Significant improvements" is not an option with this car (unless forced ind.). Yes you will be splitting hairs.If you dont do RS4 hair club for men you will be smoked.Sure you could out drive another RS4 with your lesser car sometimes.How would it be to out drive the shmuck then his HP over powers and strolls by you.99.9% street races are straight line anyway.That why I like Bicycle racing... you cant buy speed (well sort of).

The single flash gives you adjustability to run anything from 91/93 to 104.

It also lets you tailor your throttle response to fit your driving style, and lets you change air/fuel ratios to tune for different fuels or conditions.

So when can I schedule your flash?

do you still offer the free trial flash?
