DMS remap

[Charlysparrow]

Hi Guys

Has anyone used DMS services for an engine remap? Interested to know your experiences and opinions on this subject. They are quoting 479 bhp and 400 ft lbs and wondered how this transmits to everyday motoring.

Has anyone used a different supplier eg Novitec?

I'd take their quoted figures with a pinch of salt. They remapped a member's GTS to an alleged 505bhp - when driven against a standard GTS there was absolutely nothing in it. Have a search on here for the post & videos of the cars. What is the standard output of your QP?

 

[Charlysparrow]

Hi

Standard output is 430 BHP.

Not jumping into this one, don't want to spoil an already good car.

Had the remap when we had a group buy but didn't like the change so had it reverted.
My QP already had 425bhp confirmed by DMS and Millbrook so it went well anyway.
6 weeks ago I talked to Rob and asked for a special remap that left the throttle response the same in normal mode in normal driving but to come in gradually in spirited driving plus in sport mode for it to be more noticeable with far quicker throttle response.
Result 447 bhp
No noticeable difference around town but gear changes crisper
Overtaking there is more torque
Cruising at 80 plus 2 mpg better plus more responsive.
Sport mode;
Much sharper
Revs faster
Much more torque
Feels far more muscular
Better mpg
Faster gear changes and noticeably smoother.
So far very pleased and bearing in mind I'm very fussy about my toys that is praise indeed.

I remember you talking about it at the Ace, Barrie. 20bhp peak and improved driveability seems like a far more realistic outcome. I really can't see how a remap of a n/a car can deliver another 50bhp as they claim.

I'm talking to my mate who does these remaps, both for road cars and whole ECU maps for race cars. He and his colleagues reckon +25bhp tops is available from the Maserati engine, give or take a couple, assuming the rest of the car is stock. Mine will be done shortly, along with the gearbox remap.

This sounds interesting Drew, let me know how u get on!

cheers !

Will do...

No nor can I, 20 ish bhp is realistic....+50 from a remap is absurd

Locally we have a chap with an Audi A6 V10 avante and he has remapped it to 760 bhp (rolling road confirmed) and it is virtually undrivable. I had a ride and it reminded me of sitting on the bomb at the end of Dr Strangelove......you know how it ends...when is the question.

Is it possible to reprogram the ecu or gearbox ecu to get rid of that dreadful delay when pulling away in a 4200 CC , if there was one thing that ruins my driving exsperance its that , I hate it with a passion !!

Get a specialist to adjust the PIS on your car. You may also want to have a look at your throttle potentiometer - these wear over time and can make the throttle response quite poor. Mine failed recently and the difference after fitting a new one was night and day. Not an expensive part either <£300 from memory.

 

[Mr.Cambio]

Mark..with throttle pontentiometer you mean the air mass meter, or?

How did you find out that yours needed replacing? Limited performance or ce?

 

[Felonious Crud]

Barry and Drew - very interesting. Forgive my ignorance but this is purely a remap, ie no piggy-back ECU such as the FD DBW module, correct? I'm keen to sharpen responsiveness and squeeze a little more power but not interested in spending £1500 or so to do it. Barry, can I ask what your re-map cost?

Everybody has a different opinion on this for my old girl it was worth doing for the better.
When she first went on the rollers at 90,000 miles she was showing 425 brake when new she had a claimed 390.
Left with 455.8 which I felt was a good outcome.
Simon who now has her said when I took him out in her with me driving its the fastest car he has been in.
I have had 2 Ferrari's with performance exhaust's on but to this day the 4200 was the best car ever.

Going to Oceania.

The issue with rolling roads is that they all read differently and can be very easily manipulated to show varying figures. I learned quite a bit when I recently did all of the modifications to my car. Having done my research I decided to use a hub dyno to try to get the most 'true' measurement, eliminating some of the issues that can affect the reading. The guy I used maps most of the cars in a race series, all n/a engines - his experience is that there are very limited gains to be made from a ECU remap alone without any other changes on a n/a engine. I've just spent thousands and made changes to the inlet and major changes to the exhaust and the gains were not especially significant - just 20bhp. I've since had the ECU remapped and will be back on the RR to measure the effect.
With my experience I simply cannot see how a ECU remap alone can give 30bhp more on these cars.

 

[Mr.Cambio]

I agree with Mark. Our engines are non turbo. Non turbo engines are not so easy to upgrade. ECU and exhaust wont give in real life more than 30.
A friend of mine has a BMW 335 at 420 hp and is noticably faster than mine. With only the larini on mine (cats and centre) i thought that i was around 415. But real life showed that i am around 400.

Now about dynos. Each dyno has a different setup, so all measurements should be taken on the same dyno an with the same circumstances (temperature, fuel etc). Otherwise it's not worth.

No idea how the guy going to Oceania (Phil..it's you!) measured 455, but honestly i would love to measure it on mine.

As for the DMS remap on Dan's GTS (505hp), i still cannot believe that it gave nothing. My comment would be to check something mechanical for any faults like injectors, air mass meter etc, then maybe there would be some gains. And don't forget anyone that if a car is not well maintained (like oils for instance), then an ECU remap won't give the awaited results.
I strongly believe that Phil's 4200 should have been very well kept.

 

[philw696]

Thats me Nikos and my car had Shell Helix put in with new filter every 3,000 miles and always driven hard but with sympathy from my motorsport competition.
I have never destroyed a clutch in anything.
For fun do a compression test on your cars and record the readings.
Change the oil and filter and do another compression test and see what you find.
You will be surprised with the increase.
Yes I'm on my way to Hamilton New Zealand.
Phil.

 

[Mr.Cambio]

Compression test can be made via the SD3?

I know how good frequent oil changes does.

Did you ever have the injectors cleaned/serviced?

Barry and Drew - very interesting. Forgive my ignorance but this is purely a remap, ie no piggy-back ECU such as the FD DBW module, cotrrect? I'm keen to sharpen responsiveness and squeeze a little more power but not interested in spending £1500 or so to do it. Barry, can I ask what your re-map cost?

Yes Adam just a DMS remap but to specific perameters and it was half price due to the bulk buy the forum had 2 yeats ago ie £600.
If you ask Rob to copy what he did for me including throttle response you would be pleasantly surprised. I think......

 

[Felonious Crud]

Thanks Barry. I think I'm up for that and will give Rob a shout.
