Who’s Mapped Their 150s?!

[BognorMotors]

£180. You usually get what you pay for. Be very wary of that one.
Revo isn’t even in that price At £480, but it is a fantastic smooth map, we be installed loads and everyone has been happy.

 

[Andyf]

I spoke to you before Oli
I had a cheap tune done, it rattled fly wheel with power / torque spike
Save your cash get a recommended one done

@Grim Reaper . 165bhp and 350NM? Is that what they claimed as bog standard or had your engine had other mods pre remap?

 

[Grim Reaper]

As far as I am aware there were no mods done to it before I took it in, Martin didn’t mention that he had seen any indication that it had had any mapping done to it before he started on it so I guess it was stock.
It had around 4000 miles on the clock at the time of remap.

How do you go on when you take it in for a service with the remap?.

 

[BognorMotors]

Either get it serviced at an independent or get it flashed back to standard beforehand.

Fully Agree!

The rolling road can only measure the torque at the wheels and those figures are then used as the basis of a calculation to get an indication of torque at the crank making assumptions of torque loss through the transmission system and more specifically the tyres (if you want more torque to be shown on the rolling road results, stick on some skinny tyres and raise the tyre pressure!). If the power calculation has been done by the speed of the rollers, the choice of gear and even tyre circumference greatly affects those figures - they may have connected to the vehicle's own engine speed signal although the delta of accuracy between the torque and power graph lines would suggest this has been taken from the roller. For what ever reason, Pendle has decided not to show the only true value from the rolling road (torque at the wheels) which is interesting to say the least but assuming @Grim Reaper vehicle was really 148bhp/340Nm at the crank, then the 'pub bragging figures' should have been around 181bhp/405Nm after re calibrating the graph.

For any before and after rolling road graphs, you need to take the figures with a pinch of salt and just look at the delta between the two torque at wheel lines and on a diesel, how flat the final torque line looks.

 

[Dieseldonkey]

It is a bit odd that BHP is quoted by engine tuners when tests are done on a rolling road. When the concept of brake horse power is a measurement at the flywheel. Engine ancillaries account partly for losses but as you infer @Mooncat, there are further losses through the transmission and drive train. So surely it's really a bit of a misnomer quoting a BHP figure, as the total losses must be an estimate, if no flywheel measurement is taken to compare with the power at wheel.

 

[Mooncat]

To be fair, they have provided the calculated engine torque figure too but that is all based on assumptions to what has been lost between the crank and the rollers. Having calculated the delta between the two sets of bhp figures I could work out what the torque at the rollers is too but it just seems strange that the only true reading from the rolling road has not been provided.

Regarding bhp, they're only providing what the average customer is wanting......a bhp increase. If company X will give you 188bhp and company Y will give you 192bhp, you can guess where your average customer will go. The fact Pendle has a rolling road will draw in customers too as they can show the graph down at the pub and the 'custom calibration' for every vehicle again helps the bragging rights as the customer now has a bespoke product, irrespective as to whether it was actually needed. It's all a very clever way of providing extra 'value' to the customer however the stark reality is that if the tuner's calibration is good and the stock vehicle is healthy, you don't need a rolling road or individual vehicle specific custom calibration for what is otherwise a stock engine.

Something I found interesting yesterday was that the stock 150 graphs on the Revo website show a lower torque and bhp than what the Pendle rolling road is estimating so you also need to take that into consideration when looking at the claimed improvement figures if you are taken in by the headline numbers.

So How does it affect 150 DSG?

No change. You just have loads of torque when you need it. It makes for an effortless drive and oomph when needed with better mpg.

Does the DSG Gearbox need a separate remap?
I’m on 275:40:20 driving like a nun only getting 27ish in town
What improvement could I expect?

Don't forget those oversized wheels are affecting the distance being recorded so unless you've already factored that in, your mpg will be slightly better. Still below 30mpg so pretty poor though.

So only makes 2/3mpg difference Re bigger wheels?
So what are other DSG drivers getting for around town?
What will remap do mpg wise ?

 

[Lukavell]

My mpg is crap on short journeys or around town, maybe 30 on a good day. Can get around 40 on a long steady motorway run though. It seems pot luck on whether or not your van is economical, the differences if you read the various threads on here are quite remarkable!

 

[Jayjmac]

I’ve had the 150 mapped. By @BognorMotors and a revo. Totally transformed the way it drives. Lots of torque! It’s just what the engine needed. In my own personal opinion the van is much more thirsty... maybe it’s my lead foot since it’s been done and the fact it has only done short journeys but noticeably worse on mpg.. But I didn’t get it done to look after the mpg. I’m on 18s again.

My 150 DSG is horrific on fuel.
I did a 50 mile round trip today. 95% on dual carriageway with cruise set to 60mph, and still only managed 32mpg.
Vans completely empty and adopt every single fuel saving driving teqhnic possible including super gentle acceleration, judging traffic flow to avoid braking and keeping my speed down.
I'm still in disbelief when people claim to get over 40mpg in a fully converted camper with big wheels whilst cruzing between 70 and 80 mph.

As I've said many times, its the single biggest factor in me considering getting rid of it and its shamefull when compared to the fuel economy of, 'lesser brands vans'.

Totally agree but I don't think that applies only to those with big wheels!

Its been bugging me more and more regarding my poor mpg considering how slow I drive it and the fact its always empty, yet still reading others who can get 40mpg plus.
As a result, this evening I have taken ut to the next level

I pumped my tyres up to 50psi, removed the second row tripple seat and set out to make my journey

I picked a route to avoid the motorway which was mostly an old section of the A1 and a quiet section of B roads.

I barely put any pressure on the accelerator pedal when getting up to speed and once rolling, set the cruise control to 48mph. When I joined the busier dual carriageway section, I set the cruise to 55mpg and tucked in behind a lorry.
I did exactly the same on the return trip.
I also did about 5/6 miles around the local towns ring road which is a 30mph zone.
I had to blank out all the annoyed people stuck behind me.

Anyway, amazingly, the dash display recorded just over 40mpg.



So, although the MFD said 40mpg, I suspect it was closer to 37mpg, and although I have actually managed to record a half decent mpg figure, it would be ridiculous and impractical to actually drive that way all the time.

I have no doubt that if I did the same trip again giving it the beans, the mpg would be late 20,s at best.
