Chipping or Not Chipping?

[Paulopt2248]

I had my C320 CDi remapped by Superchips. The inital remap did not download correctly, and although the car went like 'a bat out of hell' it was far noiser than with the standard programme.

Superchips did a second remap, which performed much better but the fuel consumption at any given speed was heavier than before by about 10%. Superchips say that if you don't save money on fuel with turbo diesels they will give you your money back!!.

I thought long and hard about whether to keep the remap deciding to do so, as the car drove better. Superchips returned to my home on three occasions, and I tried the car with the standard programme and then the remapped file.

In the end I got myself confused whether the vehicle was chipped or unchipped so to speak..... so I went inside and had a brandy!!!.

Although I am now told I have the second superchip file, it seems to have lost the blistering torque increase and linear smoothness, and I would swear it's running it's standard programme. Time for another brandy perhaps.

The one part of the car that is often overlooked is the gearbox, this is not really up to much of a BHP increase, with many failure.

I would not do it

The gear box ECU can be re-programmed to coincide with a remap. A TUV approved remap will not be the cause of a failure but may contribute to one ONLY if there is a current problem. A remap MAY just bring the inevitable on. Sooner the better LOL

NO professional developer will overlook a gearbox (auto as manual has no config setting) if you don't programme the box then you WILL have a error code sooner or later as the ECU will not know where the extra NM's are coming from.

Aside from 'telling' the gearbox about the remap, are there not concerns that the physical mechanics of the gearbox will not be able to take the increased torque?

 

[GCLTuning]

No. We will only gain the safest power. Eg what the car/components can handle.



Take VW for instance the golf was made in a - 90 BHP
- 115 BHP
- 130 BHP
- 150 BHP

The 90 bhp will be able to take the 150 power . The 150 will take 190

The ONLY major difference is the software !

Yes I would have thot the gearbox potential would be able to withstand the greater forces of a more powerful engine.. and also with the enhanced bhp most of that raw power will be dissapated by the loss of traction between tyre and tarmac..so in effect a sensible driver wont have any problems..

I drove an audi A4 tht had been chipped and it was a joy to drive after being chipped ..totally transformed the car

I think Malcolm posted max torque figures for MB auto boxes before, they are all different.

The 220cdi will not be the same internals as the 320cdi, therefore the extra torque will break it. Another member has chipped two 220's and broke both boxes.

MB also had a 220 problem with the Brabus chips, I believe only the 320 is warranted by MB, and only for 60,000 miles if fitted from new.

Risky business chipping MB's.

I have to say I did see a 98yr 250D 5k miles 3 months old break a box ,manual, as the guy changed down to 3rd to overtake..

Performance increasing

I am a believer in the Tunit unit.
I have fitted 4 of them to Fords, Volvos and my ML270 and in the caso of the Volvo V70 2.5 Turbo Diesel it is very quick and returns 48+ MPG.

My ML 270 is quite rapid and I get 31MPG.
I like the Tunit as you can take it from car to car with you if it is a similar set up or Tunit will take it in a trade in against an other unit.
You can also increase or decrease the performance in 9 steps 0 being no increase and 9 being max.
Worth a try I would say.

The "TUNE-IT" box just sends false signals to the ECU

EG; running hotter than what is is

Also a tuning box has know limits there for you will not be making the most of you car

Tunit also use Generic files not custom there for the same programme will go on every c220 or what ever the car may be.

And there so OVER priced for a generic file £ 350

£ 340 - £ 1500 will get you a very good custom file from almost any developer - just because you can see it it donsent mean its not there !

I have to agree with GCL on this one. A good custom remap will only increase power within the parameters and capability of the car and it's parts. The Brabus chip gives huge gains in power and MB don't upgrade anything else on the car - so that gives you an idea of how much leeway there is on power / components ratio!

I've had a remap on my E280 (far cheaper then the Brabus chip £250 i think it was) from an extremely reputable company and I'm more than happy1

 

[W203-C220]

Please pass on the reputable company details!

Sounds like you consider your £250 remap a wise investment, be very keen to know where and when. I am looking into this for slightly different reasons.
I have a 2001 220 CDi Classic saloon that averages 45.5 mpg overall, low 50's easily on motorway etc. I then bought a newer (2006) 220 Estate and it only manages 34 - 43 mpg over the very same journeys. It has the sportpack wheels which must increase drag and it weighs 50kg more, but it's easily 10 mpg adrift of my saloon. I wondered if the sportpack was mapped differently?
An expert on these matters might know, or a senior member perhaps?

There is a german eBayer that sells a tuning box, similar to the tunit I think, but its about £70 including P&P I beleive? Anyone have experience of these?
They claim the usual 30 bhp or so extra with improved torque AND better mpg.

Any advice and/or info greatfully received

 

[GCLTuning]

Realy do not do it !

Thay are useless as ive said they use a crap Generic file's . Lets be honest you pay for what you get. If you have any problems do you rely think that they will be bothered to sort out there mistakes ?

If you have any questions of would just like to chat about things

Just give me a call 07791478905 or send a Email

Not quite correct....

1.9 TDI 90bhp is the older pump system as with the 110bhp, different turbo and injectors though

1.9 TDI 115 was VW/Audi's first attempt at pumpe-duese (PD) technology
1.9 TDI 130 is the most common PD engine and is different to the 115
1.9 TDI 150 is the "high output" version from VW/Audi and is also different to the 130 (injectors and turbo).

Taking the 90bhp as an example, you can fit the injectors and turbo from a 110bhp model and then re-map to suit but then you have to worry about the clutch slipping and the dual-mass flywheel grumbling from too much torque. OR you can fit transporter van injectors and a PD150 VNT turbo and get nearer 170+bhp but again, clutch and flywheel are potential weak points....

What we are say is all of these output are all achievable with a remap.

No one doubts that, the concerns are how long the engine or gearbox etc will last if all that extra power is used.

I don't think you are being entirely honest by claiming a car can take the extra power just because the manufacturer made two similiar cars with different outputs. As with everything else, it is not that simple.

We offer a lifetime Warranty ! if what your saying is true i would most certainly be out of pocket !!
We wouldn't have a succesfull business if we made a habit of damaging gear boxes and engines....we also wouldn't have customers coming back to us with their new cars if we had damaged the ones before.

We have done magazine feature's for vw bmw ECT also we do development work for porsche

Please check out our sister company, who have today MAPPED jeremy clarkson's Lamborghini and the STig's GT2 on Tuesday so you may have doubts and you have a good right to but we realy wouldt be doing this to make people unhappy !!!

Also what you have to remember that most engines and boxes now days are not running to the max and are set well under the power out-put they could handle, take the new V6, 642 lump, same engine, one is set as a 280 and the other 320, both being a 300, the differnce is how there mapped, merc even give back up to the brabus chip on both models, they wouldnt do that if they thought there engines would start to wear out before there time!!

Merc pulled the Brabus chip from the 220 CDi, I wonder why they did that if there are no risks involved?

Why then do Mercedes limit the warranty to 60,000 miles if the engine cannot wear out before its time?
