Mapping on Road vs Rollers - Which Better?
As above really. Is it better to have your car remapped on the road or rollers? What are the pro's and con's of each?
One im gonna keep an eye on.

Purely depends on what you're after. If like Cliff you want 38mpg driving to Marks and Spencer and back driving like Miss Daisy it's best to get it mapped on the shopping run but if you want outright POWER then you want it mapped on the rollers

There's a write up here on exactly that topic.

As Cliff says it's better to map on the roads, but you can get to stupid speeds when mapping, so personally i'd say it's safer to map it on a R/R IMO

Mapping
In answer to your question you need to do both to be assured of being accurate..Using the rolling road for the vast majority of it as it is far safer than hammering about on public roads for hours on end, but then carrying out final tests on the road to get accurate boost pressure readings etc..A really good rolling road set up and a tuner with years of experience are both essential to ensure the best results...Check out www.enginetuner.co.uk
The man knows his stuff...
If you are too far away from the southwest check out your most local dyno dynamics centre..
Quick question though you haven't mentioned what type of ECU you are looking to have mapped...Standard as this is possible on Version 5 onwards cars or Apexi, Autronics etc....

Oh and to answer this the best way: You will never reach boost targets on the rollers. The only true way is real world driving. If you're worried about your license hire Bruntingthorpe or even Bovingdon for the hour/day. Bovingdon is £80 a day I believe

Looks like it's going to be done on the road after reading the above and that article.
What's going to be involved - is it a case of redlining it in every gear apart from 5th over and over?

Surely a rolling road can put more load on the engine than a road maping ever could? and so a better map in any situation?
A driver and the mapper passenger on a road maping is a fixed load, what happens with 5 people in the car on a -5degree cold morning?

and then you have to adjust it back again to stop boost spikes once it hits the road

Thats strange...... as when mine was mapped on a RR it gave the same boost readings as it does on the road!?!
Anyway....
Ben v7,
The safest way is obviously on a RR, but people will argue that on the road you will get more realistic conditions etc. TBH I think the actual person doing the mapping is more important than the way it is mapped.
Regards,
Shaun.

Would you map mine on the rollers too, knowing that I dont give care for RR figures?
