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.

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).

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.

Diesel ECU tuning - education on the physics
Explaination on how increased torque keeps RPM the same for less fuel.
