FAQ's

Why isn't my speed governor removed after getting flashed with Unitronic Performance Software?
When noted, Unitronic Performance Software does raise/remove the speed governor (for off-road use only), however some exclusion apply, specifically when using our Performance Software in a vehicle equipped with an automatic transmission (non-DSG). The speed governor is in-fact removed, when noted, within the ECU calibration but unfortunately, if your vehicle is equipped with an automatic transmission, the TCU ultimately overrides the ECU with regard to speed limitations.
How do I ship my ECU to Unitronic?
We highly recommend that you first contact us to communicate the details pertaining to the ECU type and what it is being sent to us for. Once you’ve done so, you MUST ship your ECU to us, using the Unitronic Shipping Form. Please be sure to follow ALL instructions on Page 1 of the form and complete Pages 2, 3, and 4 in their entirety. Be sure to read Page 5 for important information regarding your Unitronic Software file. Please include ALL pages in with your ECU package. It is important to pay very close attention to Page 1 to ensure that your shipment has the proper exportation declaration and duties/taxes associated with it. ANY duties/taxes/tariff charges incurred from receiving your package will be billed to the client; NO EXCEPTIONS.
How do I find my ECU Part Number (ECU ID)?
There are multiple ways to receive your ECU Part Number (commonly referred to as your “ECU ID” by Unitronic).

1) VAG-COM/VCDS
2) Removing the ECU and reading the Part Number on the top cover
3) Visit an Authorized Unitronic Dealer


If you have a Ross-Tech VAG-COM Cable and VCDS, you are able to retrieve the ECU ID with these tools, without the need to visit Unitronic or an Authorized Unitronic Dealer. We’re going to assume you are aware of how to connect your VAG-COM cable to your computer and to the vehicle’s OBD-II port. We’ll also assume that you’ve already configured your VCDS application to work with your VAG-COM cable. If you are having difficulty with any of the two above, please visit Ross-Tech’s website at www.ross-tech.com.

1) Click ‘SELECT” in the VCDS application

2) Select ’01-Engine’.

3) The ECU ID and ECU Revision Number are populated once the controller data is retrieved from the ECU.
WILL MY DEALER VOID MY WARRANTY?
No, Unitronic Software does not void your manufacturers warranty simply by having it installed. The Dealership and/or vehicle manufacturer must prove that the part that you are trying to get covered under warranty failed as a DIRECT result of Unitronic Performance Software. Please refer to the Mag-Moss Act for more information regarding this law.
WHAT IS THE UPGRADE POLICY?
Unitronic Performance Software is always upgradable, regardless of which “Stage” software you started with. Please refer to the table below to determine the upgrade charge corresponding to the “Stage” you’re upgrading to.

You’ll be happy to know that there is NO CHARGE from Unitronic for reflashes. NOTE: Authorized Unitronic Dealers reserve the right to charge for their time (labor) on reflashes.
WHAT IS OBD-II (OR OBD-2)?
OBD-II stands for On Board Diagnostics II, which is the second iteration of the OBD systems, which was made mandatory equipment in all new vehicles starting in 1996. Prior to OBD-II, vehicles were equipped with OBD-I systems.

DOES UNITRONIC SOFTWARE ADAPT ON A DIFFERENT OCTANE FUEL?
Bosch Motronic ECUs do have the ability to adapt to different octane fuels. However, if you are running Unitronic Performance Software that requires a minimum of 93-octane fuel, that fuel grade should always be used. In the event that you find yourself in an extreme situation, you are able to use your own discretion to determine if using a lower grade fuel TEMPORARILY is sufficient. In most cases, if you cannot locate 93 octane, 91 octane can be used TEMPORARILY and sparingly until you are able to acquire 93 octane or higher.

CAN I CONVERT MY NARROWBAND ECU TO A WIDEBAND ECU? IF SO, HOW?
Yes, most vehicles that came equipped with a Narrowband ECU can be converted to a Wideband ECU. If your Narrowband equipped vehicle is Drive-By-Wire (DBW), then you are able to convert your vehicle to a Wideband ECU. You can purchase Raceline’s Wideband ECU Conversion Kit to make the job effortless and comes with the option to also purchase the Wideband ECU itself to make things even simpler.

If your vehicle is equipped with a Drive-By-Cable (NDBW) throttle body, unfortunately there are no options available, as there were no NDBW Wideband ME7 ECU’s produced from Bosch.
DOES UNITRONIC HAVE 12V OR 24V STAGE 2 SOFTWARE THAT SUPPORTS 262 OR 268 CAMSHAFTS?
Yes, Unitronic does have Stage 2 software for 12v VR6’s using 262 or 268 camshafts. This software is available for select ME7 ECU IDs, so please use the Advanced Software Search function or contact Unitronic or one of Unitronic’s Authorized Dealers for more information and specifics on whether it is available for your ECU.
DOES UNITRONIC HAVE SOFTWARE FOR 1000CC+ SIZE INJECTORS?
Yes, Unitronic does have 1.8T Big Turbo Software for 1000cc injectors, however, these files are strictly “race-only” files and are not suitable for street use that requires a stable idle, cold-starts, and on/off throttle smoothness. If you’re interested in software for your dedicated RACE car, please do not hesitate to contact Unitronic with your request and we’d be happy to provide a performance software file for use with your 1000cc or larger fuel injectors.
CAN I REQUEST A FILE WITH A CAT, SAI, EVAP, OR OTHER EMISSIONS DELETES?
Yes, you can visit any Authorized Unitronic Dealer and they can submit a file request for emissions deletes. However, it is recommended to contact your Authorized Unitronic Dealer or Unitronic Headquarters prior to the request to determine if a file request is warranted. Submitting a file request for emissions deletes does not guarantee that Unitronic can or will fulfill your request. Unitronic strongly urges all clients to retain all emissions components. State Emissions Inspection machines have drastically changed recently in most states in the United States recently. These new machines, when inspecting a vehicle with an emissions delete file installed on the ECU, will result in a “NOT SUPPORTED” message. State emissions inspectors are trained to reject your vehicle if it shows a “NOT SUPPORTED” code. Again, Unitronic STRONGLY urges all clients to retain emissions components and use a catalytic converter on ALL street vehicles.
IF I AM NOT THE ORIGINAL OWNER OF THE UNITRONIC SOFTWARE ON MY ECU, HOW DO I LICENSE THE SOFTWARE IN MY NAME?
Unitronic offers a license transfer for clients who have purchased an ECU second-hand with Unitronic software previously installed but licensed under a different name. ALL clients transferring software licenses must allow Unitronic to verify that it is an authentic Unitronic software file prior to the license transfer being granted. License Transfers are a one-time fee of $150. After the software is licensed in your name, you will benefit from updates and upgrades at normal update/upgrade pricing, just as if you owned the software from day one.
CAN ALL ECU’S BE FLASHED VIA THE OBD-II PORT?
No, all ECU types cannot be flashed via the OBD-II port. Bosch Motronic MED17, EDC17, and Siemens SIMOS 8 ECUs found in the latest generations of Volkswagen®, Audi®, Porsche®, Seat®, and Skoda® vehicles cannot be flashed via the OBD-II port upon initial installation of Unitronic performance software. These ECUs require to be removed and flashed on the bench using Unitronic Boot Pin flashing equipment and procedure. This procedure is roughly a 2-hour process and can be done at any Authorized Unitronic Dealer or Unitronic’s Headquarters. After the MED17 ECU has been removed and flashed with Unitronic Performance Software, future updates or upgrades can be performed via the OBD-II port.

In addition, Unitronic’s Big Turbo Software for ME7 ECUs cannot be installed via the OBD-II port upon initial installation. All ME7 Big Turbo Software installations must be performed at Unitronic Headquarters. After the initial installation has been performed, future updates and upgrades can be performed by an Authorized Unitronic Dealer in your local area.
DOES UNITRONIC OFFER FRANKENTURBO SPECIFIC SOFTWARE?
Yes, Unitronic does offer software for the Frankenturbo turbochargers. There are specific fueling requirements that MUST be obeyed in order for successful use of this specific software. For Transverse 1.8T’s running Frankenturbo’s K04-F4H or F23 turbocharger, our Stage 2+ Frankenturbo specific software requires Genesis 415cc injectors to be run at 3 bar of fuel pressure (stock pressure) with an OEM TT225 MAF Housing, retaining the stock MAF sensor. For Longitudinal B6 1.8T’s running the K04-F4H or F23, it requires Genesis 415cc injectors to be run at factory fuel pressure (fuel pressure regulator built into the fuel filter on return-less fuel system) with an OEM TT225 MAF Housing, retaining the stock MAF sensor. These fueling requirements are mandatory in order for success on this specific software. In addition, a manual or electronic boost controller is necessary with our Stage 2+ Frankenturbo specific software due to the fact that these turbocharger units are not shipped with a standardized wastegate pre-load setting. As a result, we are unable to tune for use with the N75 valve. NOTE: Running your manual boost controller inline or in parallel with the N75 valve is NOT RECOMMENDED. The N75 valve must remain electrically connected but not plumbed into the turbo inlet pipe or boost tubing. You can zip tie or tuck it out of the way at your own convenience.
WHAT KIND OF INJECTORS DOES UNITRONIC’S STAGE 2+ FRANKENTURBO FILES REQUIRE?
For Transverse 1.8T’s running Frankenturbo’s K04-F4H or F23 turbocharger, our Stage 2+ Frankenturbo specific software requires Genesis 415cc injectors to be run at 3 bar of fuel pressure (stock pressure) with an OEM TT225 MAF Housing, retaining the stock MAF sensor. For Longitudinal B6 1.8T’s running the K04-F4H or F23, it requires Genesis 415cc injectors to be run at factory fuel pressure (fuel pressure regulator built into the fuel filter on return-less fuel system) with an OEM TT225 MAF Housing, retaining the stock MAF sensor. These fueling requirements are mandatory in order for success on this specific software.
AT WHAT STAGE IS THE DSG SOFTWARE MANDATORY?
Unitronic’s DSG software is HIGHLY recommended after you reach and/or exceed 350NM/260LB-FT TQ, although DSG Performance Software is suitable and HIGHLY recommended for all levels whether complete stock, Stage 1 or Stage 3 Big Turbo. The DSG’s torque limiter is set at 350NM, therefore, beyond that level, you will begin to notice some abnormal reactions, clutch engagement, and shift patterns.
How do I engage Launch cOntrol with Unitronic DSG Performance Software?
There are four "pre-requisists" that must be done in order to get Launch Control (LC) to engage.

(1) The DSG oil Temperature must be to full operating temperature (minimum 90 degrees Celcius). You should not be launching a vehicle that has not warmed up to full operating temperature anyway.

(2) Traction Control (TC) must be disabled/off. Some vehicles did not come equipped with a TC button. If that is the case, you must install a TC button that allows you to disable TC/ASR. You should see a message on the Multi-Function Display (MFD) in the center of your instrument cluster confirming TC has been disabled when pressing the TC button.

(3) It may be necessary to disable Electronic Stability Control (ESC) on some models. This is a long coding adjustment to the ABS Control Module and is done at your own risk. You can find long coding editors that apply the adjustment to the long coding for you. Again, please do proceed with caution for long coding adjustments and do so at your own risk. It's highly recommended to always save your original long coding before making any adjustments. A VAG-COM cable with VCDS or other software programs that allow you to make long coding adjustments is required to do this.

(4) Your DSG Transmission gear selector must be in Sport ("S") or Manual ("M") mode. LC will not engage in "D" mode.

If you purchase our DSG SOftware and are unable to get LC to engage because one of the above requirements is either not possible to achieve on your specific model, or is not available, Unitronic can not offer a refund (30-Day Satisfaction Guarantee redemption) as a result of this model limitation. It's recommended to check compatibility prior to purchasing our DSG Software.
I have your DSG Performance Software, but Launch Control is not engaging. Why?
Please read the FAQ article titled "How do I engage Launch Control with Unitronic DSG Software?". If you've met those "pre-requisists" and it is still not engaging it may be a limitation with your specific model. Unfortunately Unitronc can not offer a refund (30-day satisfaction guarantee redemption) as a result of this model limitation. It is recommended to check compatibility prior to purchasing our DSG Software. Please contact Unitronic if you have any questions or concerns!
