It's quite feisty in here isn't it

I think the generic maps would allow so much "tolerance" for want of a better word. I'm with Busta, i.e. a custom map would see better results which are safer and specifically suited to your car. The generic map for the same car would probably up the boost and sort the fuelling out (safely) as opposed to maximising potential if you follow.

Best of luck with your decision SRS

SRSport

Cheers you two, that's the layman guidance I was looking for. Is the flash/generic map the £200 ones? How much are you looking at for a custom map?

I don't know for certain so I wouldn't say for definite.

I've seen generic chips/maps (whatever you call them I guess) for cars like Focus ST's and Corsa turbos (lad at work has a stage 1 chip on his 1.6 Corsa turbo) for about £250.

As an aside the custom map generally fluctuates around £300 onwards, obviously not including any licensing fee's (like ECUtek for Subaru for example) with additional cost coming in from rolling road time or other features.

I'm pretty sure if you PM'ed a couple of the custom mappers who frequent Scoobynet they will point you in the right direction if they themselves don't map your car specifically

Have you tried any Mercedes forums? I remember when I had my Luftpanzarwagen barge I joined the MBclub forum. Covers all Mercedes AFAIK

SRSport

Yes, Im on there. They recommend two. DMS and Viezu but they are quite a way from me.

Would generic maps not be safer as they are tried and tested whereas the custom maps rely on individuals and increase the chances of human error?

Dont try to turn this on me. the thread was deleted due to it going sour END OF.
Toneh all you have done for the last few weeks is take shots at forum sponsers even poor old ian godney (godspeed brakes) ..
My question is WHY?
Why are you constantly having pops at well respected people on here?

That's honestly something I personally don't have the answer too. But if it was me then I would hunt out a good custom mapper over a generic chip/map

I'd go for generic /flash map, custom map is not worth it IMO as you won't be changing exhaust etc, best just for a basic map and safer as there will be plenty of give and not close to the limits of you're cars engine etc.
Garages will charge what they want for these tbh cos they can and people pay but IMO its a very easy job for someone doing generic/upload flash map tailored for every car.

Alan Jeffery

If you're talking about engine tuning, what matters is the demonstrable results, not necessarily how you get there.
What's appropriate for some engines isn't appropriate for some others.
The trick is knowing what works and what doesn't using the basic principles of effective tuning balanced against value for money.
I personally started tuning engines in 1977 and I've been doing it ever since.
We tune cars with screwdrivers as well as laptops. Sometimes we custom map, other times we use file reflashing. We are only interested in the finished product and how it suits our customers' needs.

Would you agree Alan that there is loadable maps to regular cars that do a good job for the intended user I.e the op in this case and safe?
But tayloring a map on a car for all the nuts and crannys would be a full custom map as not many people do with regular cars and just get a flash upload map.

addi monster

A custom map wins hands down every time as everyone knows, while a custom map is being done the mapper will pick up on any problems ect that may arrise and can fix them before its too late as the map is built up gradually

Alan Jeffery

As far as diesels are concerned, there's no doubt that you could get "more" from custom mapping, but it most cases the changes made are in the ball park. It isn't much good overdoing it, and having people coming back complaining of black smoking, too much torque steer, slipping clutches etc.

Alan Jeffery

Yes, that's the idea generally.
However..

bustaMOVEs

iTrader: (31)

So the uploadable flash are a good idea unless you want to get every ounce out of it then a custom one is the way, which is what I thought

bustaMOVEs

iTrader: (31)

On a Subaru and race cars alike then yeah, I agree, but on a everyday car would you custom map it?

addi monster

iTrader: (6)

It's all down to personal choice
My personal choice would be to have a custom map for two reasons,

1st, it is safer done that way as problems will be adressed early in the map not at high boost ect where things go wrong fast,

2nd, As stated you will reap more rewards having a custom map as all avenues of power gains will be expolored.

For the sake of circa £150 in the price i would not think twice

SRSport

Why would an Imprezas engine be so different to mine? Both use 2.0l Turbo engines, one by Subaru, mine by Mercedes.

It is sounding like the flash remap is the way to go as I dont have any other mods. I received a quote from Viezu for £400 for a custom remap, not sure if they offer flash remaps. I have a feeling that there is nothing for my car out there which may mean that a custom remap is the only way forward.

I will speak to a few others and see what they say. Ant, Alan Jeffrey and anyone else, if you are able to offer either service for my car please pm me. Thanks.

Yes I would contact Alan too as he knows his stuff and a fine engine builder and that's not me kissing ****, I just know.
And subarus are more complex to map (rally heratige) and the ecu capabilities are endless, as to why so many mappers are into subarus as its big business

SRSport

Just noticed Alan is in the far South

chocolate_o_brian

iTrader: (22)

Would said map alter your insurance much as I noticed your location is West Yorks which is kinda notorious with the stereotypic brush

SRSport

Nope, this is the first year my lowest quote has not been effected by a remap. Ive moved into a better post code now, the council class it as North Yorks although the government think it is still West Yorks. All I know is that I pay £100s less and am finally free to add mods

bustaMOVEs

iTrader: (31)

Skipton then

SRSport

Nope, thats North Yorks which ever dept you are. Im in Cross Hills. Just noticed your in the West Yorkshire cachment. Whereabouts?

toneh

Dont forget guys , some prodrive maps are a generic one size fits all affair
So me thinks if prodrive/Subaru see fit that a generic map is safe and fine to use I wouldn't be worried using a generic one on another vehicle if it has a proven record

SRSport

Good point. I think the issue I have is finding a generic map for my car though

Alan Jeffery

The Mercedes isn't a difficult one to take care of. I'd expect to see around a 35 bhp gain on that one, cost £350 ish from a Superchips dealer, who are as good at that sort of thing as anybody else.
It's certainly going to pull a lot better in the mid range as well, and should be 5 to 8% better on fuel.
It'll be done serially, no spanners or boxes involved, and nothing to worry your insurance company with, being undetectable.

The big difference with diesels is you can't really hurt them, we've had a 100% success rate over 20 years of doing it.

SRSport

Thanks for that, sounds interesting but can mine be 'hurt' being a petrol car?

I thought that insurance companies can hook computers up to read the ECU nowadays and check whether it is a standard Mercedes map on it or not.

Alan Jeffery

Doh! sorry, I was in "diesel" mode there. I haven't ever seen a Mercedes petrol turbo version, and didn't know there was one!
Frankly, I didn't think the insurance companies knew their *** from their elbow and wouldn't be able to do that with a written off car anyway.
I'll reverse back out now..

I think it might be wise to get a Mercedes specialist mapper to do it and travel if you need to, as it's difficult finding a generic map as you say for you're vehicle. Or go to a well known super chips dealer locally if you can find one.

Alan Jeffery

Certainly Superchips and Alientech don't list that model, or any other petrol turbo Mercedes.
I see Quantum list it, although they spoil it a bit by claiming to be Mercedes specialists then say they "custom map" when they do nothing of the sort. Few of their dealers fall within the usual definition of car tuners.
I can't say one way or another if anybody does a good or bad job with these cars. My feeling is that asking for 30 bhp or so shouldn't be overdoing it if the file is well founded. The only thing I would say for sure is that you'd be well advised to run Super Unleaded at least and V Power if available.
