I haven't really properly updated this since the new mapping.
So here goes with a copy and paste off another forum -
My friend Phil had to take his car up to R-Tech to be dropped off for a custom map which will take two weeks, the plan was always to take my car up at the same time and get it custom mapped as well. But money and time constraints meant that it just wasn't possible, so we had arranged for me to drive his diesel Mk5 up there to drop his A3 off.
Phil and I on the way to R-Tech -
I got fed up with people taking the **** out of me on forums and basically saying that I was all mouth and had no proof of how quick my car was; so I maxed the credit card and we took my A3 to R-Tech. I couldn't quite afford a full custom map, so I was booked in for a free Torque Intervention removal on my existing R-Tech map; still worth the drive up though.
Got up to R-Tech and it was business as usual, a customer in with an AGU Mk4 Golf who had all of his work done by Awesome GTI. Awesome couldn't find the cause of this mans issues so they had agreed to book the car in with R-Tech to get the map updated. Was good fun chatting with the bloke, his car made 225bhp and he left a very very very happy man.
We stood about and chatted for 5/6 hours as you do at R-Tech and had a cracking time. Niki pulled my car on the ramps and had a quick play about, he asked me what I thought it would make and said that he'd seen my wild claims that 191.2g/s could reliably be divided by 0.8 to give an accurate BHP figure. A fairly wild claim; dividing airflow by 0.8 to accurately determine the cars power...I told Niki before he even turned on his laptop "My car will make 239bhp."
I've been getting SO much **** and hatred from the VAG forums for logging airflow so much, people have been saying it is all total ******** and ruining me for it.
234bhp dead from the first map, and after a couple of pulls to let the car settle down the old map spat out 239bhp. From a three year old R-Tech stage 1 map. Niki was so impressed with the car, he said there was very little more to give in terms of peak figures. But he would give me 100bhp more in places.
Again, this picture shows the before and after map.
245bhp with the updated custom map with Torque Intervention managed and throwing loads of timing at it.
A good guess from me? My car now logs 196g/s of airflow every time I measure it, which = 245bhp. On the cold morning on the way to work I see higher, 199g/s as my peak so far. On the road it is possible to get more power due to atmospheric conditions effecting the intercooler and intake temps.
So very happy about that indeed, it makes my car one of the fastest K03s cars out there without water meth. Now that Mylo has blown up his Leon I think I am pretty much top of the food chain which was always my goal; but I'll be pushing on with the new SFS supersize K03s TIP that I have invested in to try and break the 250 mark for myself. That's the goal.
Niki also mapped in launch control for me, which is f**king awesome fun! But more on that later...(fairly low rent video clip from a 5 year old phone; HD camera launch will be done soon)
A quick video on the rollers; although Phil missed the flames.
And a quick in car with the new mapping -
I know it was wet; but the way it loses traction now even in the dry is mental. As you can see in that video as soon as I suggest full throttle at 4500rpm in third (at 70mph) the wheels instantly light up. The torque and power is in all honesty difficult to control; I've outpowered the chassis now as well as my own driving ability. Any more than half throttle in first, second and depending on the surface in third and it just spins up so aggressively. I'm going to have to upgrade the lower arms, hubs and front roll bar to Leon Cupra R units and try to get some front camber to retain the traction advantage I used to have. With the old map I could drive everywhere foot to the floor and not really go quick enough to really be too dangerous; and it was great. Once I get to grip with modulating the throttle with this map I'm sure it will be great; but up until now I've neglected other more important areas. Other than a set of coilovers and a RARB my A3 is totally stock suspension wise. And 200bh/ton is as good as 70% more than it was designed for; I'll have to talk to Prawn about how to do this properly.
The way this map delivers is night and day to the old map; and it is a true testament to Niki at R-Tech in terms of performance it's wicked.
The first upgrade now is brakes though; because the new map is so smooth compared to the old one I am finding myself travelling a lot faster than I should be a lot quicker than I think. I'm seeking that pull at the top end that I've never had before; as though the low RPM torque is still there but it doesn't die off keeping me away from the power. It's a slippery slope for sure
To just touch on the mapping a little more, you might be wondering what "Torque Intervention" is. To explain in short terms it is a way of the stock ECU trying to limit torque by adjusting the timing, for instance if you imagined a row of timing points as being (for instance) 20*, 20*,0*,20*,20*,0*,20*,20*,0*,20*,20*,0*,20* and so on there are points in there where the timing is retarded (in old speak) back to 0* to limit the amount of torque that the car can make. The aim of TiV removal is to remove the 0* timing which is occurring and replace them with a less radical timing adjustment to make power and torque delivery smoother and much more linear.
It is something which the Bosch 1.8t ecu's do, and until recently was something people were aware of but unable to map around. Niki at R-Tech found a way to do it, and has been firmly at the top of the tuning game ever since.
The Torque Intervention can be seen by the squigglyness of the previous map, and the benefits can be seen by the linear and smooth plot of the post map as well as the ability to control the turbo more efficiently and add more timing which allows for more power and torque at the top end. Both maps are shown with the same sample and scaling rate; where as previously the sample and scaling rates would have been adjusted to make the graph look smoother and it was just a trait of the ECU.
I can't thank Niki at R-Tech enough, not only for this new map but also for what he's given me over the last three years. The map that he took off was ****ing amazing; and I'm so pleased it made the goods back on his dyno. I hope it inspires everyone to think twice before throwing their baby K03's in the bin.
So there we have it! My car is all mapped up and awesome
