Tuning the RS3 & TTRS! Episode 3- Road Trip

IE Integrated Engineering RS3 Golf R S4 at BeachThere’s a lot to getting an ECU tune right. A lot more than just throwing it on the dyno and calibrating it for today's conditions. If you read episode 2, you saw us working on the security, and doing the basic tuning for the RS3 & TTRS. However, we’re not in it to build a file that works only today, here in Utah. So, especially on a turbo car like this, we set out to build something that works everyday, all day, hot or cold, high altitude or low, and everywhere in the world.

Street Testing:

Street Testing the RS3 / TTRS VW Audi Tuning Our RS3 has been tuned since only several hundred miles were on the odometer. It has slowly gotten better and better. We found the stock boost control and torque control to be “lumpy” at best, so in addition to full throttle tuning, many many commutes and canyon sessions were logged to get that part throttle, and build up to full boost just right. It never feels lumpy, always smooth. Going back to stock is actually a bit of a shocker.

Road Trip:RS3 TTRS 8V Tuning In California

Our sea level rig is good, but nothing is a substitute for the real thing. So, we packed up our RS3, booked some hotels and headed the 11 hours or so to get to Malibu, California. This is the closest slice of the pacific coast where I can put a tire onto the sand and watch the waves crash. It was also a great opportunity to test our tuning in warm weather, which is something that definitely had to be done before release.

During this trip we found one major issue with the RS3- the stock intercooler is not even worth its own weight in aluminum. We found that on our tune from the cold of Utah, the car would rapidly heat soak and build up timing pull. We worked on this during the trip, logging and flashing amongst the alfalfa fields in Oxnard, Ca. I think the field workers thought we were insane, blasting up their deserted farm roads on snow tires!

The result of all this work is an RS3 / TTRS Tune that works in the cold- it’s been driven in conditions as cold as -5F, the hot, the high and the low, and everything in between. It works for quarter mile and it works for road racing, even with all stock hardware. It’s also set up so that these boost reductions will not happen if you equip the car with a better intercooler.

Wrapping it up:

RS3 8V Audi Rolling Shot

91 octane is fun in the RS3. Our tune adds about 100 ft-lb of torque at the wheels and this gives a real shot of fun in the mid range. The car actually has a lot more torque than an R8 V10 GT Plus! However, as we mentioned in episode 2, with all stock hardware it’s a little bit knock sensitive. We knew that higher octane fuels are where the party would really start. So, once all the heavy lifting was done, we tuned the car for 93, 100, and 104 octane fuels. This thing on 104 octane (AKI) is a beast! It delivers more power than many supercars at the wheels, and gobs more torque. It makes a Huracan feel sleepy in the mid range. Who would have expected to get that out of a ~60k car with a software tune only… What a bargain!

The stage 1 ecu tunes for the Facelift RS3 and TTRS will be available here soon, at an IE dealer or in your driveway with our POWERlink flash tool, which also offers high speed logging and code reading. The POWERlink setup will allow you to quickly swap tunes between pump fuels and race fuels as well anywhere you have internet access or can throw up a wifi hotspot. We hope you’re as stoked on the tunes as we are!

Next steps:

Our next step is really to get the “Stage 2” tuning done. This basically involves reworking the tune to work with our upcoming IE cast 3.5” downpipe with high flow cat, and a proper intercooler. We also intend to open up the octane to the people by offering ethanol and ethanol blend files, so that’s on the development path as well. It’s also nearly time to hit the tracks here, and the snow tires will give way to a set of drag radials here shortly. :D

  • So I can provide an extension to your trials... I'm in a mk7 Here in Wyoming. I'm static 6k ft up. Winter temps exceed -20°f. Also thank Tyler Davis and Damon Earl for me. I appreciate their input on tune provider and parts supplier.

    • Thanks, William!
      Actually, we are pretty much done with testing at this point and are getting ready for the full release of Stage 2 and all octanes (including E85) soon. :)

  • i have 2018 rs3 whit all bolt on possible
    what its the best number you can extract of that
    ans its an pigyback system ?
    did you leave log on original tune for go to dealer ?
    thank you

    • Piggyback or tuning boxes just can not make the same power as a full on tune on the ECU, not even close. Ours is a complete ECU tune. You can get about 517BHP on our Stage 1 tune with 104 octanes. If you want that kind of power numbers on regular pump octane 91/93 then our Stage 2 tune will get you there. It requires downpipe, intercooler, and intake only. Our Tune will allow you to flash back to the stock ECU file at any time. Do keep in mind, any tune, piggyback, or tuning box has the risk of voiding the warranty... they can always detect any of these even if put back to stock.
