They do bespoke maps using a rolling road system.
Sorry but I don't believe that any RR 'facility' are able to do 'bespoke' maps.
The files for a remap for the N20 were written by someone (presumably Superchips) many years ago. The licence to use these files were then sold off to anyone who paid them the money for the rights.
I seriously doubt whether these files would be able to be 'manipulated' by all and sundry.
The ONLY thing I believe you can gain from using a 'tuner with a Rolling Road' is a print out of of what the files have achieved to your car.
I don't believe that your average 'rolling road' establishment are software experts, which would be needed to manipulate the files (if they CAN be manipulated).
The only thing the RR people can manipulate is their RR. So, maybe their 'bespoke figures' are from the RR, not the data from the car?
If you get a bloke in a van to come to your house with the remap files for around £300, I do not believe that paying double for taking your car to a RR for them to upload the same files gives you any benefit (apart from an A4 bit of paper).
I may be wrong, but I need convincing!
Sorry Ponders, you’re correct when you say that a dyno rolling road cannot deliver a bespoke remap, my lazy response to the OP. The dyno was used to clarify the outputs of the remap. In my case the car was run on the dyno 4 or 5 times.
I spoke to Will who owns Performance Torque to clarify if he could provide a custom map that focussed on improving driveabilty and not necessarily on maximum BHP. Will wrote is own tuning files for the N20 so had the capability to provide a custom map as he was able to manipulate the tuning file data.
As you say most tuners just download a generic map to the car with no ability to manipulate the data and create a custom remap.
