My rtech map review

--- Quote from: Namsgti on April 01, 2016, 02:49:07 pm ---Hi everyone, after the great reviews for rtech I decided to go to rtech for stage 2. Here's my review
Prior to rtech-
I was running a amd stage 1 map which From there dyno made 252hp and 291 lb
From posts on here people say there dyno are not accurate !!
Rtech day-
Got to rtech nice and early was greeted by great bunch of guys.
Nicky mentioned that due to my standard back box the flow would be restricted and that I won't make the figures I was expecting, which was fair enough.
The car was on the rollers for a couple of hrs, Nicky tapping away on the laptop !!
My amd stage 1 made 266hp 271ftlb
Quite shocked!
So once all done Nicky gave me the dyno print.
The car made stage 2. 270 hp 335 ftlb would of made more if the exhaust was not restricting.
I went out to test drive it but could not really push it as the road was to busy to be driving like a prat!!
So a week or so now with the map it's not as punchy as my amd map the car before used to pull really well pick up instantly as really ideal round town driving etc.
The rtech map is very linear and you have to push harder on the pedal to get it moving, once going it pulls really well.
To be honest didn't feel the extra torque that the car now makes, maybe need to get used to it!
I may contact rtech if they can adjust the map for me.
I will post my dyno print out as soon as I figure out how to do it!!
Thanks for reading guys any comments welcomed (be nice lol)

The OEM throttle maps and boost ramps rates are to offer the feeling of a "perky car". 50% throttle tipping in an the turbo is already on course for running into a boost spike to give its boost over shoot kick. This give the placebo effect the car is running more grunt due to the perky feeling which comes with it. VW tuned the mk4 and mk5 R32 this way to make is seem more resonsive than it really is.
when tuning I don't tend to kick in the boost I will use the cams and time to aid the volume of power under the curves, which makes for a linear usable power deliver spear out over a wider rpm range. if you have been used to tipping into 60% pedal and getting the part throttle kick with the allowed over boost under these conditions then this is what your now missing. You now have yo use the full throttle and take advantage of the spread of torque.
The placebo effect and kick methods sell maps and make people go "oh this is aggressive and perky" even a low loads and conditions. but then a spread of controlled power makes a quick usable car due to the greater volume under there curves.
The biggest issues with your car is with your hardware your chocking it in a big way. The first thing is said to you before i went on the dyno was this is not going to be anything special over your current map due to the exact hardware combination which will be choking at the same rpm points, and then boom on the dyno the hardware chokes to the exact same point which is causing you to lose a massive amount of area from under the curves. from memory did I give you the option to take the car away and get the rest of the hardware sorted for stage2+ then bring it back and have it tuned to a level where you will be going WOW?
You can see on the graph where your missing out on what the engine wants to give. when driving look at your rpm range and you will see where you need to feel the grunt between shifts when giving it beans and you will see its exactly where your choking the power. to feel the additional torque you need to be in the load and rpm range where its loading up on the graph, something you wont feel on lower gear out of the rpm range, but loading up from 2000rpm in the higher gears you will be hitting the torque band nicely. basically drive it like a tdi to take advantage of the additional torque.
the grin factor comes from the full package which start from the research you do on the correct hardware to fitting the hardware which then the mapping will compliment. Go against the grain and get the hardware wrong and you will never be happy as the software mapping is always limited by the map.
Another thing is to check you are still on map setting 5.
once you removed the restriction the on the exhaust pop back and we can unlock the power and if you liked the aggressive effect setup we can give you some feeling back lower in the throttle range. On its own merits a decent exhaust will make a difference, infact the stock full cat back would give a better result than the current solution.
was this one running s3 cooler or stock cooler with poor air con rad?

Respect for the explanation!
(Even though a large amount of it was lost on me..)

stock load map vs throttle

boost n75 cap vs throttle position. the n75 is maxed out on this one due to the hardware chocking it so turbo cannot give more grunt, the map it cam in on was also flat out at 99% but the throttle would close on the midrnage.

you map 3 and 4 will have less grunt midrange.
to switch map turn engine off > ignition on > hold brake pedal > press the throttle once and off > the RPM gauge needle will move from 1000rpm to 5000rpm > press the throttle until the needle goes to 5000rpm > ignition off key out > then start car and drive.
(if you do it too slow the oil light pops up this is nothing to worry about, it just the clock think engine is reving with no oil)
GrayMK5GTI:
Can't say fairer than that, "bring it back if you want it more aggressive"
Tfsi_Mike:
Great explanation :congrats:
Simply cannot wait to get mine from Rtech and really hope my research and testing of various hardwares has left the car with the optimum setup for Niki to work his magic! :driver:
