Default Diesel Engine Chip Tuning

Diesel Engine Chip Tuning


[Note: to make the links below work, you should be logged into YahooSprinterVan]

Chip retuning is claimed to give better torque and mileage. Sprinter Store seems to have documented better torque, but better mileage confirmation does not seem to be as well documented - my InMotion retuning does not seem to have resulted in better mileage as an example. There are also other concerns with regard to the impact retuning could have on the engine's longevity. Read the several well informed discussions archived on Yahoo SprinterVan.

Sprinterstore
Diesel ECU Tuning Module
Rechip the Sprinter 2.7 ECM for improved performance under load conditions. Not as clear that there is a benefit under no-load conditions.

Diesel ECU chip replacement
Read this for DC's OM 647 replacement chip policy (my guess is that this policy also applies to the OM 612s).
http://autos.groups.yahoo.com/group/.../message/30687

InMotion
InMotion. This is not a chip replacement, but a retuned OEM chip. See Yahoo SprinterVan Post 25662 for other claims. See also 27647 for a mechanical engineer's comments on the physics. Remember the adage of being an informed consumer. InMotion rarely answers email or questions. Telephone contact is almost impossible - but I have never seen a complaint of lost/no service. Several names are associated with the address, but probably one person. InMotion does not follow up on promise to give instructions on ECU removal and packaging. See DIY:Cruise Control for ECU removal. Pack in Express Mail Flat Rate envelope w/ 1 layer 3/8" bubble wrap. See Post 32605 for additional service of cloned replacement ECUs at about $200 less then DC.

Diesel ECU reprograming - InMotion
Discussion on governor reprograming options. Note that as of 10/2006, software for reprograming latest Sprinter (2006?) ECU chips for the governor not available.

Diesel ECU tuning - InMotion Austria
Home site of InMotion USA. Note that this site implies a chip replacement. However, whatever the description, in the US it is a reprograming, not replacement of any component of the ECU.

I've already seen the postings on Yahoo. The story remains incomplete to me though. Why did MB de-tune the Sprinter for the US market?

It seems to me that two of the most important things in purchasing any vehicle would be power and MPG. This is especially important in the US market, where HP numbers are one of the first thing anyone looks at.

Why would MB intentionally de-tune the Sprinter for the US? The marketing departments would never have allowed this, even at the expense of reliability.

There also seems to be a consensus that the tuning kits also improve the driveability of the Sprinter. That's kind of hard to overlook.

I don't think MB is ever going to answer that question to anyone's satisfaction.

I think it's best just to do what you want to do to your Sprinter, take any risks and accept any rewards or consequences.

I fitted a chip to my 311CDi (chassis cab with a 11ft box body) that I brought from a company in germany via eBay (there called avrieb or something similar) noticable power increase but best of all around 20% better fuel economy.
I gather one of the main reasons why US vehicles are de tuned is that Diesel is poorer quality in the US compared with UK and Europe(Cetane levels etc) and emmisions

I dont know if it makes much of a differance to emmisions but I do dsconnect it for its annual service and I have used it for around 18months
it plugs into the socket at the front of the common rail, and there original lead plugs into the chip.

regards
Jon

I have heard that all European diesels are detuned because of fuel Quality.

I have an 09 Sprinter that I am curious to chip.

Any chance of getting some current feedback on doing this tuning thing on new models. I think diesel fuel is suppose to be getting better here in the US or is that just not so and if yes, does that encourage us to retune the engine? I am particularly interested in the 2013 and 2104 Sprinter model years.

Hello Friends.
I am wondering if anyone has had luck with these in line tuning chips:
http://www.ebay.com/itm/121107813293

I have a 10000 mile trip coming up and if this does anything it could pay for itself in that journey.

Thank you,
Nolan

I can't answer your question.

I can say that I don't see a 2.7L engine listed under Sprinter. All I saw was 2.2L and 3.0L engines. You should find 154 hp for a 2.7L 5 cylinder engine on the list.

Wow Vic,
You are FAST!
I will write to them.
I am planning on doing the Green Diesel tuning in the spring once I have some new equipment.

Yesterday the shorty lost a drag race to a BMW. I hooked up good and got the hole shot on him but lit up a tire when the boost came up at the same time there was some moisture on the road. I got connected again but it was too late. I came home thinking about more fuel, more boost fresh programming and .............. .......
