SMARTflash Stage 1 Power Upgrade [Leon Cupra (5F)]

Transmission: Manual
TCU calibration: Not Included

The mountune Stage 1 upgrade delivers phenomenal performance for the Seat Leon Cupra and Cupra R (5F) with either manual or DSG transmissions.

Based on over a decade of tuning vehicles to pass OEM sign-off, the mountune Stage 1 offers the highest quality calibration, providing improved drivability, response and of course, a substantial increase in both power and torque, all vigorously durability tested to provide peace of mind that reliability is maintained - even when the power is increased to 360PS and torque is raised to 500Nm.

It also boasts enhanced vehicle functionality, can be used to monitor gauges via the OBD port, and also includes a performance meter as well.

A return to stock option is included, together with an anti-theft option.

The mountune Stage 1 is available in two versions to fully exploit both manual and DSG transmissions. The DSG version also includes a fully optimised transmission calibration option (you can choose this option above). This is programmed into the TCU (transmission control unit) by the SMARTflash app, which then allows it to maintain higher torque levels through the revised clutch pressure optimisation. Shifts are faster, giving harder and quicker acceleration through the gears, whatever level of performance your car has and the launch control benefits from a revised, more aggressive strategy.

For manual owners that don't want to fit an uprated clutch kit, the mountune Stage 1  calibration includes multiple selectable torque modes within the performance calibration as standard, so you can still safely run increased levels of performance without the fear of near instant clutch-slip.

Whilst not essential, it is recommended to achieve and maintain the quoted power figures under hard use, an aftermarket induction system should be used, like the mountune X3, which the Stage 1 calibration has been fully optimised for.

Features:

• Power increased to 360PS
• Torque increased to 500Nm
• Supplied as standard with Stage 1 calibration (featuring multiple torque mode outputs, return to stock, anti-theft and valet options
• DSG version includes optional mountune TCU calibration fully optimised for DSG-equipped vehicles
• Enhanced launch control

Additional functionality:
• ECU and TCU data-logging
• Performance meter
• OBD gauge display
• Fault code reader
• Easy DIY installation

In the box:

• SMARTflash OBD bluetooth adaptor
• Zip-up mountune case
• mountune badge

Please Note: Whilst every effort is made to provide calibration support for all known available base variants, due to the number in existence, there may occasionally be a delay in enabling support for your vehicle. Should this be the case, options to provide this support will be made available, or you will be offered a full refund until specific calibration for your vehicle can be provided.

Stage 1

The mountune Stage 1 calibration dramatically improves power and torque output across the entire rev-range; peak power is increased to 360PS, with torque raised to 500Nm.

It also features a host of additional features and functionality accessible via the SMARTflash app.

For maximum performance the mountuneStage 1 should be used together with a high-flow intake and is optimised to work with the mountuneX3; the pressure drop achieved using this setup removes yields further improvements in peak performance, throttle response and also enhances induction noise.

Power figures achieved using 99RON fuel (Stage 1 is safe to use with 95RON). Power output may vary based on individual vehicle condition, fuel quality and method of testing.

Ready for transmission

The mountune DSG TCU calibration works in harmony with the Stage 1 engine calibration to fully exploit the maximum available vehicle performance and engine torque output.

Our SMARTflash OBD Bluetooth interface and SMARTflash app allows you to easily reprogram the gearbox's calibration inside the TCU (Transmission Control Unit). This allows the transmission to maintain higher torque levels through the revised clutch pressure optimisation.
 
Shifts are faster, giving harder and quicker acceleration through the gears, whatever level of performance your car has.

The driving mode strategy itself is also optimised to suit higher power levels, giving a more coherent gear selection profile. Switch the controls over to manual and you'll have real gear control, quite literally at your fingertips - no automatic upshifts, no kick down until you decide you want it.

In addition, launch control will get you off the line quicker through allowing more boost at launch and increased launch RPM.

    Perfect for power boost and gives you options to change maps without the OBD reader in!

    Mountune are a bit of an underdog vs the other big tuners for *** cars BUT they have a proven they are bang on for my Seat Leon Cupra 300. Power figures are true to advertised as you can data log and use the ECU connect app and the OBD reader which gives you a file to can take into a spreadsheet. Great connection speed and accurate data, I've used it for diagnose a minor misfire with my car! The TCU / DSG tune was rocky at first but it depends on your preference of aggressiveness, e.g. my route home the car was in 3rd most the time rather than 6th at 40ish mph in Drive Mode. I emailed about this and requested a change which Mountune happily obliged so drive mode shift points was closer to stock but still retained the quicker shifts and clamping pressure. Initially the map switching, between 3 power modes, did not work on my steering wheel as it was originally tested for a mk7 Golf and using the cruise control reset button the mk7 steering wheel. However Mountune changed this so maps can be changed with the indicator stalk which is where the cruise control controls are on the Leon. All in all, they are accommodating and the software is really good with years of testing behind them. It also gives you options if you don't want full beans all the time. Highly recommended. Only thing I would suggest is that they email you to ask if you want longer overrun and how aggressive you want the DSG tune. Overrun is wayyyyy to long on their standard ECU map but again, that is preference.
