The Fiesta ST 180/200 is a fantastic example of a modern-day turbocharged hot-hatch. With a lively chassis and punchy 1.6T engine, it delivers a genuinely rewarding driving experience. But there’s so much more hidden potential just waiting to be tapped into.
If you want to get the most out of the 1.6T EcoBoost’s stock BorgWarner KP39 turbo, the PERON STG2 tune has been developed to optimise performance, when used with supporting hardware upgrades. These include a PERON High-Flow Intake, a PERON Sports Cat or De-cat downpipe and a PERON intercooler.
Our brief was to create a car that was faster and more responsive, without affecting everyday drivability. The PERON STG2 ECU upgrade is designed to work in harmony with the hardware upgrades to produce a more thrilling driving experience. ay of transforming the performance potential of the Fiesta ST.
The PERON STG2 ECU calibration produces up to 210whp and 275lb/ft when combined with our essential supporting hardware. These figures were achieved using a Dynojet Dyno (24m above sea level), our Demo Fiesta ST Mk7 using 98RON Shell V-Power Nitro fuel and a PERON High Flow Intake System, PERON Cross Over Pipe, PERON De-Cat Downpipe and PERON Performance Intercooler. The ambient air temperature during the test was 19°C
There’s more to a PERON ECU calibration than a set of dyno figures. We focus on making the car more rewarding and, dare we say, fun to drive.
There’s no point in having a power figure to boast about if the car is not enhanced as an overall package. And we think we’ve achieved this. In the real world, this translates to harder acceleration, a stronger midrange and consistent, linear power all the way to the redline. With PERON software, your car can also be quickly and easily put back to stock. Try a PERON STG2 ECU calibration with the essential supporting hardware, and you won’t look back!
Fuel Type - Our STG2 calibration is designed for 98RON fuel only
Essential Supporting Hardware - PERON High Flow Intake System - PERON Intake Hose - PERON Cross Over Pipe - PERON Sports Cat or De-Cat Downpipe - PERON Performance Intercooler
Please note: Installing the STG2 calibration without the recommended hardware list above may result in failure to make the quoted power / torque figures. Power figures may also vary according to ambient temperature, altitude and quality of fuel used.
With over 20 years’ experience with the Bosch ECUs, our chief calibration engineer has developed an ECU tune, which we believe is the best in the business. Over many months and thousands of miles, we gained a detailed knowledge of the ECU in order to maximise its potential. We then set about increasing the engine load by raising the boost pressure, optimising ignition and cam timing, as well as lambda and other parameters.
Minute adjustments were made and logged in order to create an OEM-level of drivability. Factors such as throttle positioning and a perfectly smooth idle are critical factors that our engineers obsess over, while engine safety is paramount. The PERON STG2 ECU calibration retains OEM knock control sensitivity and other factory safety features to ensure the highest possible levels of durability. Having tested the PERON STG2 ECU calibration for over 3,000 miles on our own demo vehicle and applied it to thousands of cars worldwide, we are confident it represents the very best system currently available when used with our essential supporting hardware.
We see the PERON STG2 ECU calibration as the next step for anyone serious about improving the performance of their Fiesta ST with upgrades to the intake, exhaust and cooling system.
