Having had all the parts fitted for MR300 I decided it was time to upgrade the map. Unfortunately I did this at the start of lockdown. So I was unable to drive the car. Now I'm back to work and using the car daily i feel it's a good time to review the map. It's great. Nice smooth power delivery. Not sure what I was expecting. My car was a strong 275 before and I cant really notice an additional 25bhp. What I can notice is the extra torque. And it makes the car much easier to live with. I think before on the MP275 map it was great but something was missing. The MR300 fills that gap. It's a no brainer if you have the hardware needed. The only down side is it never came with a new badge and you have to pay postage for an email.
You should've received an m-flag badge with this kit, so if you didn't, please contact our sales team. Glad you're enjoying the MR300 otherwise!
Bit confusing trying to update firmware to controller. Key wouldn’t be seen by laptop when trying to download but when I had a chat with the tech gurus at Mountune the confirmed it had auto loaded to controller. Connected to car and 5 mins later software download complete. Focus ST now total awesome with 300bhp on tap. Excellent purchase just visual upgrades now.
Installed the MR300 the difference is huge, the mtune easy to use the installation also super easy . Only problem is mounting on dashboard the wire not long enough and as i live in a hot climate hard to stick to dashboard.
