pmsl.
I normally refrain from such outbursts, but seriously, I respect R-Tech as a tuner but this guy seriously needs to calm down a bit, and stop wagging his tail and humping the table leg every time they are mentioned.
I know of 2, maybe 3 highly skilled tuners, but they are not widely publicised because they don't hang out with the kids on facebook or come onto forums. It's not all about punching numbers into the mapping software. The engine is just an air pump and there's no way a K04 can pump enough air in to make a genuine 400hp. The VV Race cars see 400ish from a hybrid K04 sure, but not a straight 04 off the shelf that's thrown onto 8P S3s and ED30s. Take the engine out of the car and put it on a proper engine dynamometer and it will be nowhere near 400.
Mapping is just manipulating the rail pressure to see 0.8 lambda in the meat of the boost and lambda 1 every where else. Nowhere do I see boost pressures quoted, air mass figures, ignition timing at WOT, intake air temps etc etc to support these hp numbers thrown around.
Normally you see 340ish hp and torque from 1.4 bar spike, held at 1.2 to the red. Now 1.4 is pretty close to the ragged edge for a K04. Either 400 is coming from seriously over spinning it - turning the intercooler into a nice interheater in the process, so WMI just cools it back to where it would be normally running less boost - or there's some pixie dust sprinkled on that engine. 60hp cannot come from fuel and timing adjustments.
Oh and TiV is just sales speak for flat spot removal.
I struggle with making a true linear 400hp from a hybrid, by linear I mean 400hp close to peak rpm, they all struggle due to one huge factor common with the k04-064... the exhaust manifold which give high emps which contributes to knock and low post head effectiveness. not many hybrids run a linear 400hp without the wmi in there, Take the l04xx which I tuned on a 9.8:1 CR CDL s3, knock limited sub 400hp by 6500rpm, yes can pull out timing and run more boost which at 1.7bar is more heat and it dont work. That ended at 412hp with wmi then went on to prove the point on the 1/4 mile by running a 11.9s.. L0400 I hit al knock wall at 385hp non wmi.
TIV is the name I used to promote a unique method of tuning, on the tfsi med9 it was about removing the anti buck maps ARMD maps, which are also in play in the me7 1.8T maps which over the year all tuners missed out, we was the first to remove them and tune with a refined ignition output which opened all new methods to gain performance under all conditions, the main one was lower egts. I started to use the term TIV mapping, to say remove the timing based torque interventions, I then shared this info with another tuner, you might know him? Bill at badger5? he then started to use the term TIV, which I had trademarked to stop him confusing people.
by the way 1.4bar peak is so 2008..... its at 1.7bar @4400rpm now because its all about tuning the k04 like a small turbo and not trying to flow linear like a big turbo, tune it for the power band which is going to get used...... and by turning the inlet cam maps in to maps for performance and not to save the planet to meet strict emission laws there is a whole new avenue of power to unlock!!!
By reading your past posts on the forum it seems you dont understand the concepts of the tfsi gdi engine? you question why is dont run stratified injection so what is the point?? the point is and the development was to build a high compression engine which can run hot lean clean and safe on the edge of the knock window. With pre mixed combustion setups like the 20v 1.8T the engine would knock its tits off, but they got around the knock at high cr by running homogeneous fuel injection which gives a perfect boundary layer, to aid cooling and emissions. The tfsi can run happy lambd 1 with homogeneous lean injection. Yes the mpg would be much better if it was stratified lean burn setup.
I can see your point fully dude, but make your own mind up and not what others tell you.
Any questions about tfsi or tfsi tuning please feel free to ask me I am more than willing to help everyone.
