Quick tuning offers custom remapped tuning software files and professional ECU services for almost all the popular petrol and diesel vehicles from market. Usually, a normally aspirated (N/A) car might be tuned by approx.7- 8% of their power and 8-10% of the torque. It is done by a modification of some fundamental parameters: fuel pressure, time of the beginning of dosage, ignition advance angle and the calibration map of the lambda probe. Cars equipped with a turbocharger (both the diesel and petrol ones) can be tuned by 20% to 30%. In this case, apart from the parameters mentioned above, pressure characteristics of the turbine is modified (of course in turbodiesels the fuel injection angle is adjusted – not the ignition anticipation angle). The fuel consumption decreases by approx. 8% for turbodiesels and increases by approx. 7% for turbo petrol engines. Some automobiles may be improved significantly, whereas the modification of others is not possible at all. We believe cars should be set up for local conditions and unique customer requirements, as no car is the same !
You will often see modifications available in stages. Typically manufacturers of performance parts and car tuning companies use stages 1 - 2 to denote the state of tune provided.So what does a tuning stage mean and what are the differences between a stage 1 and stage 2 tune up.There is a wide divergence of opinion on the web about these and some manufacturers merely mean option 1 or option 2. The commonly held perception of these are as outlined below.
Stage 1 tuning is a bolt on or single modification that requires no other work to the car or engine.You can consider a stage 1 modification to be referred to as a fast road mod,it is suitable for a daily use car.It can be used in isolation with standard components. Overall reliability and daily drivability of the car will remain. Obviously any power increase will necessitate a reduction in the manufacturers inbuilt safety margin.
Weak components will sometimes fail but in general a stage 1 tuning modification can be added to a car without incident or problem. A stage 1 modification will usually be enhanced further with the addition of other performance parts. Examples of stage 1 mods, remap, sports exhaust silencer, air filter or brake pad upgrades. (These are all simple single bolt on parts.)
Stage 2 tuning is a little more aggressive than stage 1 but needs to be added with other parts. It will give a power gain but will usually require the uprating or replacing of other parts to work. Examples of stage 2 modifications include a hybrid turbo which requires a different manifold or diverter valve or remap to work at it's best. Reliability of the car should be unimpaired but you will pretty much have lost any scope or margin for error in the standard manufacturers setup.This can be considered a track day tuning option. Service intervals should be reduced and you can expect to perform a major overhaul on the engine every few years in some cases. Examples of a stage 2 modification, aggressive remap that requires a stronger turbo/diverter valve, sports exhaust requiring new headers and different mounts, Internal modifications requiring fuel to be uprated etc... (the concept is that you need another mod as well.)
