TECHNICAL DATA IN THIS GUIDE IS BASED ON 2017 AUDI S3
STAGE 1
Required hardware upgrades:
Please remove the factory snow screen as well as trim the air duct to allow increased air flow. This gives much more air to the engine, and we have seen power up to 450-470PS using the stock intake with this modification. If you have an aftermarket intake installed, you can ignore this step. However, we do recommend using the Factory airbox with this modification instead of an aftermarket intake system.
1-step colder plugs for IS20-IS38 equipped cars:
Recommended Spark Plug Upgrade | Model | Notes |
|---|
Denso | 5749 | pre-gapped (slant tip) |
Brisk | ER12S | Gap to 0.024" |
NGK | 4905 R7438-8 | Pre-gapped (slant tip) |
OEM (NGK) | 06K 905 601M "RS7 plugs" | Gap to 0.024" |
For all slant tip spark plugs check the gap to ensure it is not overly above spec but in most cases, they are 0.024-0.028 out of the box. These do not follow the same gap procedure as a standard spark plug and should be left alone.
It is recommended to check the spark plug gap after 5000 KM (3100 Miles) as well as the TQ, and to change them after 10,000 KM (6500 Miles) for optimal performance and safety.
STAGE 2
Required hardware upgrades:
Hardware upgrades as tested:
STAGE 2 w/MPI
Required hardware upgrades:
Hardware upgrades as tested:
File | Supported Fuelling upgrade |
|---|
Stage 2 w/ MPI | Hellcat 525 LPFP
980cc MPI Injectors (CTS Turbo MPI kit tested) |
Stage 2 w/ MPI | EQT Brushless LPFP
925cc MPI Injectors (Precision Raceworks MPI kit tested) |
This option is for customers who have installed MPI on their vehicles and require ECU tuning to run the additional injectors without issue. Please note that during testing, this hardware upgrade did not yield additional horsepower. Power gains for this hardware upgrade during our testing were octane limited.
Supported Fuel for Stage 1 and 2
Octane/Ethanol | Supported Ready files |
|---|
91 Octane | Yes |
93 Octane | Yes |
STAGE 3
Stage 3 - developed and validated for the following hardware:
HPA Downpipe with 200 cell catalyst**
CTS front mount intercooler**
Eventuri Carbon fiber intake
Turbo Concepts TCQ38600 Hybrid turbo.
MPI upgrade with 980cc injectors (CTS Turbo kit was used for the development vehicle)
Low Pressure fuel pump upgrade (Hellcat 525)
Spark plug upgrade (See above spark plug table)
Continental ethanol content sensor*
** Or equivalent performance
* Dyno graphs for this tune were produced using E40
The below hardware configurations are supported by our Off-The-Shelf 'Ready Files' available for the Stage 3 tune price. Hardware upgrades that are not listed in the below table will require custom tuning and must be approved by one of our Calibrators before tuning can begin.
Stage 3 Ready Files (OTS) | Required Hardware upgrade |
|---|
Turbo Concepts TC-600 v.1
Hardware Recipe A | Turbo Concepts TCQ38600 Hybrid turbo (Version 1) Performance Downpipe Intercooler upgrade Stock HPFP Hellcat 525 LPFP MPI upgrade with Bosch 980CC injectors (Required) Continental Ethanol Sensor (Optional for customers wanting to run E40 or Flex Fuel) Minimum 93 Octane fuel
|
Turbo Concepts TC-600 v.1
Hardware Recipe B | Turbo Concepts TCQ38600 Hybrid turbo (Version 1) Performance Downpipe Intercooler upgrade Stock HPFP RS3 LPFP pump and controller MPI upgrade with Bosch 980CC injectors (Required) Continental Ethanol Sensor (Optional for customers wanting to run E40 or Flex Fuel) Minimum 93 Octane fuel
|
*NOTE* Hardware upgrades outside of this list will require Calibrator confirmation that a tune can be produced. Do not use Stage 3 tunes without confirming compatibility with Calibrator.
* Rear O2 sensor delete is not available for later 1.8T and 2.0T TFSI and TSI with SIMOS engine control units (as opposed to Bosch MED9 and MED17) with exhaust manifold built into their heads. It's because they depend more heavily on the rear O2 sensor to ensure a more accurate AFR. This is consistent with our desire to maintain OEM-level reliability and smooth drivability, especially at high performance.
Supported Fuel for Stage 3
Octane/Ethanol | Supported Ready files |
|---|
91 Octane | No |
93 Octane | Yes |
E40 | Yes |
True Flex Fuel | Yes* |
*True Flex Fuel is currently only supported for some box codes. To confirm if your vehicle is supported with Flex Fuel files, please submit your box code in a Ticket.
CUSTOM TUNING
We do offer custom tuning for vehicles and projects that require more than what we offer through Instatune with our ready-made downloadable tunes.
The process of custom tuning is much more involved than standard tuning and also requires heavy involvement from you, the customer. It is a commitment from both parties, but it is all in an effort to yield the best possible result for your vehicle, you, and us as your tuner.
Cost for custom tuning starts at $1699 and can go up from there depending on your requests and vehicle setup. Due to the volume of custom tuning requests, you should expect an approximate 8 week lead time for a Calibrator to be able to provide your initial base file. This can also vary based on the complexity of the vehicle setup and tune, as well as how quickly logs are submitted to us.
Custom tuning requests or inquiries should come prior to having the vehicle completed. In some cases our tuners/calibrators will recommend or request specific parts to be used as our tunes have been proven with these specific items. It is not uncommon for us to not be able to tune a vehicle for certain hardware. If the hardware is already purchased and installed the calibrators may request hardware changes prior to tuning. Any parts revisions during the process that would deem the necessity of a re-tune will be subject to re-tune fee of 50% of the custom tune cost, above the current custom tuning price.
You would be required to have access to logging software (such as VCDS or OBDeleven) and would be responsible for providing specific, quality logs in order for our calibrator team to make necessary adjustments and fine-tune the software we provide.
It is highly recommended to have access to a dyno, and to be prepared to incur costs for dyno time. Street logging is acceptable as long as it’s done safely and produces quality logs that we can work with. We are not responsible or liable for any damage or incidents occurring while street logging.
