Remap gains

[Herishi]

What's everyone's experience with the gains in power torque and fuel economy from remaps?

I have had a quote from Celtic tuning stating an increase of 103hp and 147ft/lbs and then another local company stating 20-30hp and 40-60 ft/lbs

There seems to be a huge difference!

Is the bigger gain at the cost of reliability and longevity of the engine?

What are people's thoughts?

These quotes were for a 2007 e280. the gains offered on the lower remap are only equal to a e320 so I'm amazed they don't offer more

Yours is the same engine as the e320, so id say a 30hp - 40hp on top of the e320's power would be about right.

It all depends on how fit your engine is. My Volvo's were 225hp std, with a "310" Rica map that's what it should have been, but rarely would they reach that figure, They usually were more around 250 -260hp.

I'd be very dubious of the claims of 103/147 gains. Is your car a diesel or petrol model.
Unless turbo or supercharged you won't achieve big increases. The second quote far more realistic.

Herishi's is e280 cdi

It was always interesting to see peoples face when they started tuning there cars (Volvo crowd) and they thought they had around 350hp because they'd done this that and the other,then get it on the Rollers and it put out 280hp lol.

Hmmm, still wont get another 100+bhp from a remap

Not sure what a e280 cdi puts out std. But yes id be very surprised also, why not get a before and after figure steve on a Dyno?

Had my 320 v6 done at msl. Upto around 265bhp from 221ish and upto 450ftlb and very happy. Told them celic quote 290bhp iirc and he said its a bit unrealistic.! I could of pushed msl to go foe a bit more bhp but it's not worth it as it's well within its limits so you can hammer it if you choose. Mpg slightly better but I didn't by it for that.

I do always stutter when i reply to these sort of posts as most members don`t like what they actually read....they always think that the bog standard Mercedes is the way to go....Lol

Even both of my Indy specialist i go to when i asked about a remap...one said "isn`t it fast enough already " and the other said " we get a lot of injector or turbo problems with remaps" which i would of thought right up his street for earning money...

Nevertheless i did about 3 months Googling here and there and questions galore before making my mind up.

This is the way i looked at it....i bought my C Class some £2500 cheaper than it should of been at the MB Dealer so therefore in my own stupid way i have that amount of money to spend on it if i want, so i thought have the remap done and if i get problems the money is there for repairs....who cares as i am retired and still single!

Same as merc85, we are old Volvo members, i had my Volvo which had a remap to compare with so knew that it could be advantageous to have it done.

I decided on Celtic Tuning forgotten why but also this is the remap that BlackC55 uses for his customers and he did recommend it to me.

Well, i finally had the remap installed with a settling in period during which i could have the original map put back if i wanted to as they save it.

First driving a bit dismayed as i was expecting a rocket ship but that happened for me the next day as the ECU had learnt what i wanted from it and so performed for me as it had adapted fairly quickly.

You can see the figures quoted.......are they true?.....who knows but it performs better than my 280bhp Volvo and not only speed but the Volvo was at 23mpg and the diesel Merc. is at about 38mpg using the power.

It did go to 45mpg at 50/60mph for an hour but i can`t drive like that also i think diesels love a thrash to cut the crap and so reward the driver with superb and effortless torque and instant response especially in S Mode.

My Indy Specialist doesn`t know it has a remap but does say the engine is in superb condition even at 99,700miles. No funny noises, nothing just as it was and that was about 9 or 10 months of redlining each time i go out. I don`t thrash the hell out of it just use the power when i can safely.

It`s run on nothing but Shell Nitro Diesel and the correct dose of Two Stroke each fill up. No black smoke at all.

You can compere the spec. of our engines in the pictures and also i note the ECU is identical to the engine. So i would of thought the same performance.

Oh and we'll worth it as it goes very well ☺

I compared my Merc w211 e320 cdi with a Volvo 850 which had just come off the rollers that day and was putting out 257bhp. The performance of that car on the move was exactly near as dam it the same as my Mapped e320 cdi.

Baring the the Volvo weighed 1490kg dry, Id assume the Mb tobe around 100kg- 150kg heavier id say the output of mine must be around a similar figure. It was actually quicker over the 1/4 drag than my Mapped 850r Volvo aswel.

Cant wait for the next dyno day to see exactly what it is.

Told them celic quote 290bhp iirc and he said its a bit unrealistic.!

I won`t get into any arguments about torque / bhp figures i just go on practical abilities to sort of try to prove things.

Forget the total weight of the car etc. different engines but keep to class like my C class.

My 7g Estate Model in the Mercedes book 0-62mph 7.1 @224bhp

Remap managed .......................... 0-62mph 5.9 @Celtic 290bhp

C55 5g Estate................................0-62mph 5.4 @367bhp

Therefore:
C55.....+.....Celtic.....+......Std.
367.....77.....290......66.....224

5.4.....0.6.....6.0......1.1......7.1

So you can see approx. as conditions during tests are different but just for comparing why would Celtic be so unrealistic??

Ok, different gearbox / engine etc. but the motor still has to have acceleration figures to compare.

The difference in bhp is 77 and 66 but the difference in seconds is much more 0.6 compared with 1.1.....

How did you measure your 0 to 60 Keith as I've found it very had to get a definitive answer with a stop watch and passenger! The figures were all over the shop. We really need to put these cars on a dyno which was the plan but ran out of time.

There is a plug OBD device that can do that, cant remeber where it came from tho?

Also i used a app on a friends I phone and it was pretty close when i used it on the 1/4 mile, it read 15.07 @91mph what i achieved was 15.2 at 90mph

Those Celtic figures are for a stage 2 re map.
Stage 1 provides 33 bhp & 81 ft lbs torque extra to original, still impressive though

Hope that works im not great with tech stuff lol

 

[parksie14]

Incidentally Celtic have re-mapped my 122 Vito,50 bhp & about 80 ft lbs torque, much more enjoyable to drive & no flat spots

I was a bit disappointed that the local remapper only quoted gains that would put it on par with a 320, if They had said 250hp+ then I would have gone for it.

My gut feeling is that 290hp might be asking a bit much from the engine

How's that? its the same lump as the e320 / who's the local mapper btw?

Not sure if turbo and injectors ate the same on 280 as 320! Thought I'd seen they were different somewhere but been bed since then so might be wrong.
