Cheers for finding me Boost leak, was a swine to change but at least it's all sorted now. Would have never found this without smoke testing it. I'm sure I'll be back in the future !

5starTop bloke. Had a remap and some performance tweaks done at a really affordable price. Highly recommend

If its Economy you looking for' the best value for money is getting a remap, you could save upto 20% on fuel bills, by fine tuning the ECU from the vehicle and its parameters to give you more low down torque, this enables less gear changes for example on motorways, The vehicles engine doesnt have to work as hard. Be it Petrol or Diesel theres massive gains hidden and ready to be unlocked transforming your vehicle, For more information get in touch.



Remapping via the OBD port is just a simple matter of connecting our software to the vehicles On Board Diagnostic socket, There is no need for ECU removal, The majority of vehicles are OBD but some newer are protected, Using the OBD socket we will pull the vehicles file from the ECU, this then lets us modify the file using various programs, once we are happy with the upgraded software we then reconnect via OBD and upload your new software to the vehicle.



Here at Unit 9 Remaps we have the most upto date advanced Hardware & Software, Most of the latest models from manufactures have protected ECU's, this is to try and block any software changes, With the latest technology we can remove the vehicles ECU, place it on the frame on the bench and using special probes read the ECU data allowing us to unlock the manufactures software' Allowing us to change areas that we request. For example a 2011 1.6CR VW Golf is a tricore protected ECU, we will have to remove the ECU from the vehicle to carry out the desired work, This will result in a slight price difference, Contact us for more details.
