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?

Great question:) One im gonna keep an eye on.
Personally im worried about having my car driven (or me driving) at stupid speeds for a mapping, although i`ve heard its better to map on the road than on the rollers:(



Cliff

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 :lol1:

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

Not sure where he gets his info from ;)

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....

You think so :D My cars never been near a set of rollers for a long time.

I was taking the piss ;):lol1: Going for a power fc soon ;)

ooops :D

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?

The mapper will use fourth gear to get car mapped, then ask you to give it some through the gears so he can check it is hitting the boost target in each gear.

:hjtwofing :lol1:

You know it big boy :p

Thanks for the replies.

Looking forward to it. :D

It's a newage so just remapping the standard ECU.

RR if you're interested in bhp bragging.

Road mapped if your interested with how quick it is on the road.

road mapped,when and where ever possible

sam elessar (the dentist) mapped my evo, the guys **** hot. And it was done on the road ;)

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?

Can you please explain why that is the case? Remember that I do 99% of my mapping on the road, but also run some of the cars I map on the road, onto the rollers.

Only when the 'number' you get during road mapping isn't high enough to please the customer ;) and then you have to adjust it back again to stop boost spikes once it hits the road :D

handbags anyone
martin

Thats strange...... as when mine was mapped on a RR it gave the same boost readings as it does on the road!?! ;) :D

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.

Mine was mapped doing stupid speeds on the public highway! just ask the bloke in the other scoob that pulled up along side as it was being done :D

Bang on. You only get out of mapping what you put into it. Ideally I would like to map on an airfield like brunters, no trouble with sustained speed, no trouble with stopping for some time to think about what to do next, and ideally plenty of time to allow it to be done properly. A rolling road however is a very good sanity check, although with ecutek mapping, the road dyno function of deltadash is very good for comparison work.

Paul

Like a recent one that made very good figures on the RR where the customer was particularly interested in RR figures? ;)

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

I would suggest having it mapped on the road by Bob Rawle ;)

Possibly, don't knock it until you've tried it. While I was at it, I might actually tell you first hand what I have done in the past, so you don't have to retell an incorrect version of events based on half the information.

Paul

'Possibly' sounds a bit uncommitted. Under which circumstances would you map mine on rollers and under which circumstances wouldnt you? :)
