Tdci Tuning, TDCI Remap, Turbo Diesel Common rail Injection
TDCI means Turbo Diesel Common rail Injection. Instead of having a distributor pump with a separate pipe to each injector, the common rail is just that. A single pipe (or rail) connected to all four injectors. The fuel is allowed through only when the ECU triggers the injector. These common rail systems run at extremely high pressures (in excess of 25,000psi) so please do not attempt to dismantle one unless you have the relevant experience. You might very well seriously injure or kill yourself!
When a manufacturer develops a new car they have to take into consideration all of the conditions it may be subjected to in all of the regions in which they intend to sell this model. This means instead of just optimising the ECU’s program or ‘map’ to deliver the best performance or the most fuel efficiency they have to make compromises to the map to take into account these potential differing operating conditions. These could include sub-standard fuels, extremes in temperature and altitude, differing emission laws and even the possibility that vehicle may not be serviced on a regular basis and in accordance with the manufacturers recommended instructions.
ECU remapping is taking a read from the ECU’s processing chip of the vehicles standard compromised map and adjusting various parameters within the map such as fuel pressure, boost pressure (on turbocharged applications) ignition advance and throttle pedal control amongst others to release the true performance from the engine. It is a completely safe process as it is just giving the engine the performance it should have had in the first place before all the compromises were applied to the original programming. Every engine will have its own unique map and by adjusting this we can fine tune the characteristics of the engine; unleashing more power and in many cases reduce fuel consumption too.
