MR230 (mTune only) [Mk7 Fiesta ST]


This option is for customers who wish to upgrade to MR230 using an mTune handset and who fall into one of the following three categories:

  • MP215 customers who have all the required hardware installed for MR230 but require an mTune and MR230 calibration.
  • MT215 customers who have all the required MR230 hardware (including an mTune) but require an in-field firmware update to their existing handset.
    In-field firmware updates are facilitated via a bespoke upgrade key. Once ordered we will send you steps to follow in order for you to provide us with your specific mTune serial number. A key will then be generated and sent to you which will enable you to update your mTune's firmware using the AP Manager software.
  • Customers running all the required MR230 hardware but using standard software, requiring mTune with MR230 calibration.

  • mountune alloy intercooler

    Mr320 mtune

    Very easy to use. Impressed with the immob map also, leaving the car for a time maped to not start is a great feature..quick remap and your away.

    Completes the ST

    My car was already at MP215. I had the MR230 map along with all the other supporting hardware. This is not a cheap upgrade but worth it on so many levels. The car is much more eager across the rev range and just wants to go. I always felt that (lack of) noise was a real let down with the ST but there is now some real drama to it. Having said that, you could still do long motorway trips without it being too much so for me it's the perfect balance. Haven't had the car on track yet but the only question remaining is if it needs the LSD.

    MR230 Upgrade

    Absolutely amazing, I brought all the hardware for the MR230 and fitted everything while already being MP215. Looking at Mountune's chart on power differences i was a little worried as I wasn't sure if i would notice a big difference between MP215 and MR230. Being at the stage where I needed to get it done as I fitted the sports cat and the engine light was on, i didn't really have a choice. Luckily Mountune is fairly local to me and i waited with the vehicle while it was being fitted and i was talking to Fred saying i'm not sure what to expect. Fred said "MR230 is one of my favourite upgrades we have ever offered, it makes a great car even better" that really made we quite excited to drive the car. On the way home I have to agree its an animal the way it puts the power down is amazing. Highly recommend this if you have a MK7.5 ST 180. As always it was a real pleasure seeing the team again, although being in this Period of Uncertainty, but they are handling the issue very well.
