remapping? diesel motor

I would suggest that you look around $1K+ as it involves dyno work,specialised operators and time. Any thing involved with squeezing horsepower costs.Long term you can't beat cubic capacity.

thanks Aus-Kiwi, I have no idea what that means

You buy and fit a gauge for exh temps, from Exh manifold.

for a true reading.
and a little Led unit for on dash for other readouts.

The Computer tune is for resetting the electronics in veh main computer to control activation of things at different rev.s and fuel rail timing. Basically.

It's a LOT more than that. but realistically
it resets your current comp timings to one change or more upwards.

a great improvement as long as done. INSIDE the max settings allowed.

The MFG's always start a new model with several UPDATES in reserve in the computer. to allow such
on the annual updates of that model vehicle.

A BIG CON REALLY.
Detuned at start to allow "Look what we done" at next model upgrade.
And the one after. and after el al.

If towing. they a great improvement. along with Converter Lock up if you have an Auto.

Yep pretty much the same with elect things . Sell the simple first then latter bring out a better model . Phones are prime example . The factory worry about warranty, durability when a new model comes out also ..

Thanks again guys, as you see from the avatar, its a 2010 sprinter 515, we do not tow. The main problem is I think its holding gears too long before changing up. When I read a previous post I thought I understood that this would be covered in the mapping. As I said I REALLY don't know what I am asking for, do I take it to any diesel specialist, or ultratune or does it need to go to a dealership. Or have I totally misunderstood.
Sorry to be a pain but is hard when you have no idea, and I have been ripped off because of my ignorance in the past.

When was auto properly serviced ? Tweaking to wastgate or larger exhaust ? How old are injectors ? I cleaned my air filters in Broom . Not same motor . Was surprised the the difference !!

Poppy sore eye · Senior Member

Wastegate, larger exhaust, mo idea what you are talking about!.
I give up, I will take it to a dealer and hope I van trust them.

Aus-Kiwi · Guru

May get rapped taking to dealer ? Waste gate is the valve that bypasses exhaust to maintain correct boost .. Bigger exhaust or less restrictive let's turbo work better as it works on pressures . Sometimes a restrictive muffler is fitted ? But a basic service can do wanders, fuel filters etc .,

Poppy sore eye · Senior Member

it is serviced regularly, all injectors replaced 12 months ago, it was just reading the comments I thought this remapping may be a solution, I agree I may get ripped of at a dealer nut general mechanics have done this before. As soon as I walk in they realise I don't know anything, that's why I was asking if anybody knew someone in Mel . Thanks anyway.

Contact a specialist diesel tuner. To quote "Let your fingers do the walking". Ring several, they don't have to be in your area. You'll then get an idea of what and how much needs doing. As for your auto, repeat the previous. Hope this helps.

What makes people think that some local mechanic can tune a modern vehicle engine better (and as reliably) as the multi billion dollar manufacturer who designed and built it?
Warranty? Forget it.

Not talking about Joe the mechanic. These are specialist diesel tuners that only work with diesels. Often the dealer has the apprentice doing the work. I only go to the specialist for work. A GP doesn't do brain surgery, as an analog.

True Rod, manufacturers need make their vehicles to cover ALL uses where a specific requirement, like towing, can have the ECU mapped to do the job of towing better than any other tasks.

Do you think the diesel specialist knows about the design considerations of that motor?

Will the manufacturer maintain the warranty on a motor that has been "messed about with" by a non authorised "specialist"?

Will that "specialist" replace that motor at his expense if it all goes pear shaped?

Will the motor still be 100% legal after modification?

Pretty big risks here. $10,000? More? For what benefit?

Cheers,

Peter

OK, I give up. Please disregard any advice I may offer. Save your phone money. It's obvious "I know nothing". BTW I notice you have not given the OP anything constructive, unless you call "bagging" someone else's suggestions as constructive. 2010 model is more than likely out of warranty.

Friend just did his. His motor held gears for too long and it didn't have much oompth. Consisting of plugging in a device to read the computer program. Machine gave him a number which you look up on the internet for what that is. Turned out it was a sensor on the gearbox. You then get asked if you wish to change your setting to the new setting, press yes and that's is. Unplug and its now going like it should be. All that remapping is, is setting an EPROM (Erasable programmable read only memory). Quite common for those to get spiked and confused. If that happens your computer goes back to basics. Macka got it right, most times its easy money. Rob.

Hi Poppy sore eye smile

I sent you a private message regarding a Mercedes mechanic in the Melbourne area who will be of assistance to you.

Depending on ECU . They have parameters to which to fine tune by. . Btw a guy in LA or Germany can tune a car in Aust these days over the internet ..

Am I not permitted a view unless it agrees with yours?

I would have thought that keeping the $1,000 in the pocket was constructive?

Ahh, gone down to $1000.

All I suggested was to ring and enquire.

macka17 · Guru

Not if he "not happy Jan" . with his.

And a proper retune. from a REPUTABLE Diesel tech place
WILL improve it no end.
Well worth the money

As said. ALL Mfg's have reserves built in.
Only time you may find a problem is if you have the LAST version of that model
before they doing a complete update to next complete model.
Even then. If keeping same engine. Normally only the electronics are basically changed.

Just make sure you get a "hard copy" of it as well.
So any wksp "updates", that reverse what you had done.
Can be redone again.

Most veh's are "updated" daily.
Tyres.exh,susp.lights. bars.
the chip or retune are just another improvement from basic factory settings.
WITH plenty of reserve. ALWAYS built in from factory.

ALl vehicles are improved by a little fiddle somewhere.
especially your little "Perky?" driven truck.
That's an underpowered, but run forever beast if ever there was one.
(apart from the few 350 chevvy ex-mining trucks).

$1,000 to get it done and another $10,000 for a new engine if it goes pear shaped?

For a bit more power?

I hired a Maui motorhome when I was visiting New Zealand last year. It's built on the Mercedes Sprinter platform just like yours. So it would have the 2.1-litre turbodiesel four-cylinder engine rated at approximately 110kW/330Nm. Not a lot of grunt, so acceleration was fairly leisurely and any hill I encountered gave the motor a good workout. I really liked the specs of the engine - for such a small displacement, it had a huge engine sump capacity, so the oil change intervals were huge. Big tick of approval from me.

This very same motor also does duty in Mercedes Benz's passenger vehicles, like the C220/C250 CDI or E220/E250 CDI. All these use the same 2.1 motor, in different states of tune.

When you look at the specific outputs from the sedans, you'll quickly work out that Mercedes has drastically detuned the engine in the Sprinter. It could be for reliability or safety or economy reasons, I can't say for sure. However, what's clear is that the motor as found in the Sprinter is definitely capable of producing more grunt. For example, the E250 CDI produces 150kW @ 4200rpm and torque of 500Nm @ 1600-1800rpm These engines are capable of autobahn speeds all day long, so the motor in your Sprinter can definitely be tuned to give some more power and torque.

Why did your injectors get replaced 12 months ago? How much mileage has your 2010 done?

That IS a tiny little engine block for that size vehicle.
Tuning to nearer limits will help. but the weight of load alone would make ME nervous.
WITH THAT SIZE DONK (have to be all electronics for that output)

You can go forever with the electronics as racing Formula 1 cars show.
BUT physical weight will make a difference to longevity.

It your case I wouldn't be comfortable with any more than 1\2 the MAX allowed.

Me. I'd be buying a truck with bigger donk beforehand.

The old Perky's Peter use are an example.
I've worked on and owned some. 2/3/4 and 6 cyl Perky's in boats. (All old rattlers,
even when new).

Can't tune too far or they would go bang.
Waaaay indertuned. built for longevity.

BUT they life forever normally and cheap as for rebuild kits.

I rebuilt mates 3 pot. complete incl head shave.
for less than the cost of doing up the head on my Yanmar qm20 2 potter.

These tiny Euro's are NOT going to have a long engine life in those trucks.
Pistons. rods and valves.chains. Can only stand so much at those pressures.
Maybe,,, living on the flat. Less loading.

In that engine size case Peter.
I do agree with you. Physically too small.

6 and 8 speed transmissions help big time . Don't see F1 racing with 3 speeds since the 40's . Modern engines basically fail when things go wrong . I mean other things like EGR blocking up or particle filter no cleaned . Bad servicing etc . The ECU protects engine as much as it can . But people ignore the engine warning light and keep driving .. I don't think even the franchise dealers are to spec on new vehicles either ? I dad issues with my work truck cutting out . After 4 different dealers it was found to be the cam sensor !! Just don't break down where you shouldn't be in work vehicle !! Lol

6-8-15 cog boxes do help.
BUT after a life of physically lugging weights up and down hills of that size with 2 ltrs.
Regardless of electronics.
the mechanicals are going to wear out or break. Sooner than a larger mechanical base will.
3 ltr/3.5 ltr.

When it come to physical weights not rev's. Cubes Do last longer with less problems.

Why do you think trucks ,power boats.don't go down in engine size with all this technology around.
They want their engines to last the million or more.
Small high tech. Will NOT.
