Fiesta and Puma MHEV MAXD 1R Remaps now available!

We are delighted to announce that MAXD have completed the highly anticipated 1R suite of calibration files to suit the Fiesta and Puma 1.0l MHEV models.

With up to 185bhp and 275nm available on 155ps models and up to 160bhp and 270nm available on 125ps models, this 1R calibration will give incredible gains on your mild hybrid Puma or Fiesta right across the rev range!

The new 1.0 MHEV platform is already a Pumaspeed favourite; early in 2020 we purchased our own 125ps Puma development car to get deep into the new software and MHEV powertrain. A stage 1 file was written after only hours of owning the car and comprehensively tested even during the unfortunate Covid-19 lock down. The lock down was a blessing in disguise for our mapping development as it gave us the time to write many new protocols and huge array of mapping changes to bring to life the most powerful mapping to the new Fiesta and Puma which retains all the standard emission features.

After a solid 2020 of road testing and dyno development, we are proud to present the new Fiesta and Puma 1.0 Hybrid Stage 1R remap with over 40nm more than any competitor mapping and around 10bhp more than other generic maps available on the market.


What is the power increased to?

There are 2 power outputs for the new 1.0 MHEV powertrain, 125PS and 155PS. In the past Ford used to simply offer different levels of remapping to create the different levels of engine output. However, for the MHEV 1.0l EcoBoost platform there are some major differences between the 125PS and 155PS motors. The 155PS models have a different turbocharger, and have some internal engine changes meaning the mapping is not transferable. 

For 125PS models we are seeing peak figures of up to 160bhp and 270nm.

For 155PS models we are seeing peak figures of up to 185bhp and 275nm. 

*The above quoted figures are based on 99 RON fuel, we also offer a slightly milder 95 RON map with around 10bhp and 10nm lower figures.



The Results Explained

Power is the headline number you will always see written in bold type everywhere to give credibilty to how good a remap calibration actually is, but power is calculated at very high revs... in the region of 6,500rpm in the case of this 1.0 motor, and lets face it, when was the last time you as a Puma MHEV driver thought about reving to 6500 in daily use? Let's concentrate on an explanation of torque then, to show you how the true drivability of the car will feel. 

Torque is the low down pulling power you experience when initially accelerating. In simple terms, the longer the remap holds onto this the better. Typically in the 1.0 MHEV Puma this can start as low as 1500 revs thanks to the electric motor and should hold on as long as the exhaust gas flow from the turbo will allow until around 4500rpm.

Often tuning companies get headlines for the maximum power and torque achieved by their remaps, which whilst this may win followers on social media, it doesn't win races! The area under the graph is far more important than the peak numbers in creating a faster and more effortless car, fortunately with the MAXD mapping, you don't have to compromise on either.

Realistically 1500-4500rpm tends to be where you actually drive the car on a regular basis and this is where Pumaspeed and MAXD have concentrated most of the new work with the new hybrid power train for the unbeatable MAXD Stage 1R mapping.


How do I get the 1R remap on my car?

We offer the incredible MAXD 1R calibration via two methods.

Workshop Fitted - Fitted within the hour at Pumaspeed HQ in Wakefield, West Yorkshire via our master tool From £349

MAXD Flash Programmer - Available worldwide through our dealer network via our iFlash home tuning kit allowing you to remotely remap your own ECU via our simple to use Windows based software, also allowing you to return to your stock map at any time From £449


Is it reliable?

As soon as we could get our hands on the new MHEV powertrain, we did, in the form of our 125ps Puma. In the 18 months we owned the car we covered over 20,000 miles, almost all of which were whilst running this 1R calibration with no reliability concerns at all.

Power and torque could actually be increased even further than the already incredible levels we have reached, however the issue we found with this was maintaining temperatures and making the figures repeatable. Unfortunately there is an awful lot going on in this complex powertrain in a very small engine bay, the stock intercooler is also very small and both the intercooler and radiator struggle with fresh air flow through the relatively small grilles in the bumper. 

We therefore early on made the decision to peg the figures back slightly to make sure that oil, water and intake air temperatures were kept under control, meaning the quoted power figures are achievable again and again with no risk to reliability long term.
