NOTE: The E85 calibration just isn’t a flex-fuel type tune. The tune will work with E85 immediately from the pump, each summer season and winter blends (ethanol content material can fluctuate from E60-E85). This tune requires solely E85 to be pumped into the gasoline tank. Gasoline blends and race gasoline mixtures shouldn’t be used, and engine injury may happen if the wrong gasoline or octane is used. We strongly suggest an ethanol content material gauge be used in an effort to monitor the precise ethanol content material on the pump you might be utilizing.

When switching fuels, it takes about 20-Half-hour of regular driving for the brand new tank of gasoline to totally flow into by way of the system when stuffed at E. Please decrease load (don’t ground it!) till you may have pushed the automotive for a minimum of Half-hour. Ethanol content material analyzers put in near the gasoline rail may also aid you see when the ethanol has absolutely run by way of the system.


As with all automated transmission car, the ECU and TCU computer systems work synchronously to correctly apply torque to the autos drivetrain in a secure and dependable method. Inside each the ECU and TCU, there are manufacturing unit security tables that restrict total torque output based mostly upon what the manufacturing unit first tuned the automotive for. The ECU studies the output of torque from the engine to the TCU, and the TCU decides if that is appropriate, or an excessive amount of. Whether it is an excessive amount of, the TCU will command the ECU to scale back torque output based mostly upon its security tables.

034Motorsport takes a holistic method with its Dynamic+ tuning, and goals to retain as many OEM security protocols as potential. Whereas it’s potential to tune across the manufacturing unit TCU torque limiters from the ECU facet, that is achieved on the expense of torque security options which are integral in protecting your transmission working safely. 034Motorsport’s calibrators tune the ECU to work with the TCU to supply correct torque values, and recalibrate the suitable security ranges for the TCU.

With elevated energy, comes elevated warmth. With elevated warmth, comes the necessity for added administration. For each cost air temperature and engine coolant temperature, 034Motorsport has applied key security options to maintain your engine working optimally and safely in just about any situation – similar to the OEM calibration. Substantial effort was spent on balancing the commerce off of cost temp for energy, and bettering the compressor effectivity in order that it would not generate an excessive amount of cost temp.

Cost Air Temp: When the cost temp exceeds 80*C there’s a discount in energy output. When the cost temp exceeds 85*C there’s a extra important discount in energy output. This cost temp limitation is there to forestall knock occasions from extreme cost temps, which may severely injury a motor. With these security measures in place, you possibly can confidently drive your automotive, from the highest of Pikes Peak to Loss of life Valley, figuring out the manufacturing unit ECU has optimum efficiency and security coated..

Coolant Temp/Fan Technique: From the manufacturing unit, Audi likes to run hotter water temps to scale back fluid friction losses from cooler, extra viscous oil. Whereas higher for effectivity, this technique turns into a security difficulty when masses and warmth are elevated. 034Motorsport calibrators have rescaled the coolant temperature targets and fan management methods to focus on decrease coolant temperatures when in larger warmth situations, permitting the automotive to run inside a secure warmth vary rescaled for the added warmth that comes from tuning the engine. As soon as once more, because of this 034Motorsport calibrators have stored your confidence in security absolutely intact from the OEM configuration.


The Dynamic+ Tuning choices for the EA839 3.0T all retain the Begin/Cease engine performance, however enable customers to set reminiscence for the system based mostly upon desire. If you don’t want the Begin/Cease system to run, flip it off through the in-cabin button and the automotive will retailer that choice even after key biking the automotive. If you want it to remain on, choose it to be on through the in-cabin button. That is achieved in a totally OEM vogue, serving to improve the general expertise of driving your automotive!


Whereas E85 gives substantial will increase in energy, it requires about 30% extra gasoline than normal pump gasoline per ignition cycle. Using quite a lot of gasoline stratified injection methods, 034Motorsport calibrators have additional optimized the manufacturing unit fueling system to have the ability to adequately assist full E85 on manufacturing unit {hardware} for Stage 1 tunes.


As with something in life, it’s all the time greatest to be truthful. This particularly applies with regards to reporting torque outputs within the ECU to the opposite management modules within the automotive, in addition to displaying correct increase readings to the driving force through the increase gauge discovered on the Digital Cockpit. With 034Motorsport Dynamic+ software program, the ECU is reporting correct torque values to crucial techniques just like the TCU to make sure that all security techniques are intact in each management models, and the added torque from tuning is correctly adjusted for when driving/shifting, together with all security techniques designed to guard the engine and transmission.


Volumetric effectivity (VE) is how properly a motor can transfer air/gasoline out and in of it’s combustion chamber, the upper the effectivity, the extra of the air/gasoline might be transformed to torque and energy. Each engine has a volumetric effectivity that varies with RPM. Because of this, each inner combustion engine has torque that varies with RPM; some motors, because of superior options like variable valve and camshaft timing, can create exceptionally flat torque curves throughout a broad vary of RPM merely attributable to optimizing VE utilizing these superior management options. Regardless of this means, each fashionable engine, particularly with pressured induction, could have torque values that modify throughout the RPM band. Within the case of the three.0T EA839, there’s a dip in VE at 3000 RPM, or stated a unique manner, VE may be very environment friendly from 2-2500 RPM, and continues to be very environment friendly by 3500RPM, however drops to a barely decrease degree at 3000. For reference, all of our dyno charts present a dip in TQ at 3000 RPM for this very cause. It is very important observe that this isn’t an issue with the tuning, and we may have very simply smoothed out the torque curve in our charts to attenuate this, however we selected to go away it for the sake of accuracy and transparency.

The conventional VE drop at 3000 is substantial, and greater than what our closing energy numbers recommend, however as an alternative of smoothing the curve to cover this, we selected to sort out it head on utilizing our tuning experience and technical mastery calibrating these ECU’s. A method to fight the VE drop is to extend increase by way of this area, however as an alternative of merely turning up the increase utilizing the increase management technique, we re-engineered the ECU’s torque request operate to focus on a better TQ by way of this area. The result’s extra energy and torque utilizing the ECU’s manufacturing unit management technique, which retains all manufacturing unit ECU performance and security options in place. Finally we’re capable of make the dip lower than the pure VE by elevating increase a secure quantity, however increase can’t make up all of the distinction. What we have now achieved is optimized in efficiency, security and performance – simply as if the manufacturing unit had achieved it.

Eager observers will observe that this dip is current in different firm’s marketed charts too, however grealy smoothed over and diminished visually, so consumers needs to be conscious. This dip is within the VE of the motor, it’s regular for all engines, and there’s no cause to cover it or be something lower than clear and sincere about this motor’s efficiency.
