My R8 is a 2012 v10 manual. I sent ecu to VF for the hex tune last month and also added the pop and crack effect.
Car has been acting up after the tune. 1st gear between half and full throttle after 3k rpm the car rock back and forth. It felt like a huge turbo lag and the turbo had been turn on and off on and off as long even my feet is on the throttle very steadily.
Also at 4th or 5th gear gear between half and full throttle over 5k rpm my car started Shaking. I can see the speedometer struggle to go up to 6k rpm as if the car is struggle for fuel.

Dropped off my R8 at Motorwerks houston the day before which is a VF authorized dealer so that vf can diagnose the problem.
Shout out to Travis at Motorwerks and Abe at VF sales department for being on top of the issue.

However the vf tech department has been a little slow in responding.
My guess is the pop and crackle effect is throwing the ecu off on throttle mapping and fuel.
Will keep y’all posted.

Interested to hear more. I just inquired about the pop and crackle effect. Was curious if this can damage anything.

Pop and crack effect? Didn't know you can add that via a tune


Is that to be made to sound like a gen 2 R8 or a Huracan ?

My Viper did the pop and crackle thing after changing the exhaust and I did not like it. I know it's personal preference, not for me. The sound I get when downshifting in Sport Mode is enough for me.

Waiting on this too. Porsche and Mercedes use it to great effect with the push of a button.

Essentially you tell it to inject a little bit of fuel even when you are completely off throttle (normally fuel is completely cut) which ignites in the manifold/exhaust system making glorious sounds. Well, it can be done this way - I assume that is what they are doing.

A little update. Travis from Motorwerk called me last Friday and told me that VF is working on a OBD II port flash for all 2012 r8 so that we don’t have to mail them the ecu every time we need to tune or detune. Hope I’ll have some good news for y’all 2012 owners by the end of this week
