Just been having an chat about mapping of engines (in the car)

I reckon of all the forums I use PassionFord would have the most users who have benefited from having their cars remapped. So which is better a live map on the road, or on a rolling road

I'm told the only reason tuners live map on the road is because they cannot afford a proper rolling road which seems daft...

you cant exactly simulate road conditions on the rollers. and as people tend to drive their cars on the road thats where they should be mapped!

Definitely NOT on the road, as you really need to get up to the max speed of the car. Bruntingthorpe is the place to do it - is only Ł60 an hour and a good mapper should be able to check and adjust the car in that time .

I’ve had my car live mapped on the road by MSD and the good thing about this way is that you get the car mapped to actual road conditions

Get the basics sorted on the rollers, then go out on the road (or, as mike suggests, a private track).
That should reduce mapping costs

No rolling road accurately simulates the road.
So it you want it mapped to use on the road, thats where it needs to be mapped (well brunters to do it legally!)

If you want to make maximum power at a rolling road shootout though, a road cant accurately simulate a set of rollers, so it needs mapping on the rollers.

So it depends on where you want your car to make the power?!

Thats what I was thinking

This all came about after watching that Lotus blow up the first time round on 5th Gear.

They spend 2 days on the rolling road and still it ran lean. I was thinking that might not have happened if it had been tuned live on one of those runs.

Appreciate the info lads

Absolutely spot on mate, if they live mapped it that failure wouldnt have happened!

You could actually SEE the EGT's were high on that run and a melted piston confirmed the view!!!! Shame we cant get a vid of it.... it was pretty fooking hot

Ollie MK5 Turbo

Was it not the NOS that made the damage?
Don’t you need a remap to run NOS probably?

Jim Galbally

wht you mean you could SEE it stu?

Stoned

No they fitted the NOS on a later day. This was the initial run.

I actually said to Nicole, fook me, look at the EGT's on that Lotus!! And then it blew up

I see dead engines....everywhere

foreigneRS

the rolling road that they used, like most others, did not have proper road speed airflow. if you don't have that, and not many in the world do have full frontal air flow at high speed (we have up to 70mph), then it becomes very unrealistic, particularly for forced induction cars with air to air heat exchangers.

No
No

In the case of a properly fitted wet kit giving only a 25% increase in power on a turbocharged car with poor intercooling.

Oh my, not this topic again......LOL

I am sure the last time this topic was up, there were death threats, beatings, dog napping, stabbings, bottlings and everything..........LOL

Dont worry, If it kicks off i will throw it in the river Dan.

ROFL @ Dan - I was thinking the same thing

Ask the bloke who got his Lotus mapped on the rollers that performed on Fifth Gear against Rod last night.

GARETH T

i like to do all my mapping on the road, because i havent got a rolling road

if i had the choose i would do most of my mapping on the rolling road, then take it outside and check/adjust my work

sunny

Dyno if you can afford it (to get the absolute best out of your engine in a proper controlled safe environment), followed by a rolling road with good cooling followed by a proper balls out session in proper live conditions (to adjust the map to REAL time in-car conditions).

COMEDY DAN

I like to use an Ordnance Survey map for my mapping.

A good favourite of mine is the landranger 152, which covers Northampton and Milton Keynes.

This also shows railways, electricity Pilons and animal sanctuaries.......

...i'd say map on rolling road and then check on the road.....


...awaiting more death threats

MSD set my Cossie Westfield up on the road in the pissing rain and it runs so much better now it's like a new car...They found things I didn't even know were wrong, made changes, told me what they were doing all the time. Went out several times and got piss wet as Westfields leak a little!! Top blokes... Would have been better and easier for us all in the dry but then they are based in Blackpool....

Don't forget some peoples rollers lie....or so I'm told.

Ta very much

i cant really see the advantages to setting up on a rolling road tbh, other than the weather. all i see are disadvantages. i prefer to have my car set up in as close to the conditions its going to run in as i can.






p.s see you in grizedale kenny , dont forget the laptop pal

Mark Shead

All of the above have there own benafits, Yes you can map on the Engine dyno and the rolling road, But before the car is realised to the owner IT HAS TO BE LIFE MAPPED on the road or Brunters no ifs or buts,
as you cant simulate cylinder temps on any of these like you can get on the road which is where its home is,
If the engine is a dyno queen and never used on the road then that is the best place to map it,
I use all of the above

Jim Galbally

70mph sideways inches from trees in the woods?

fookinhell stu and kenny have got bottle

Mark Shead

If that is where its driven then thats the place to do it,
I mapped a 100mph F1 Ski boat this year and you can guess where it was mapped Yes 100mph on water, I have done many Mad things in my time but this tops it I was scared shitless I kid you not but still managed to do my Job correctly
