Frequently Asked Questions
1. Will the warranty on my vehicle be effected?
No manufacturer generally allows any modifications to their vehicles including the fitment of aftermarket wheels etc. ECU remapping falls into the same category. However FRC software is completely undetectable to any diagnostic equipment the manufacturer will use. It is recommended that you discuss any modifications with your service advisor if your car is still under warranty.
2. How long will it take for different phases on my car ?
For Phase 1 - Generic Remap, the process takes 4 – 6 hours to complete.
For Phase 2 - Custom Remap, the process is much longer due to the extra changes that need to be made for the vehicle performance enhancing modifications. Please contact FRC for more exact timeline for the Custom Chip process for your vehicle.
3. Is the remapping reversible ?
Yes, the Remapping is reversible. The customer needs to bring the vehicle to FRC & the stock software will be loaded onto the ECU.
4. Is the chip-tuning detectable by diagnostic software?
No please see explanation below

ECU software consists of 2 main parts:
1) Program
2) Map Data

The program area is the “operating system” of the ECU. It reads data in from the various sensors, does calculations & then outputs data to control the fueling, timing (& boost pressure on turbocharged/supercharged vehicles). It also does the diagnostic functions of the ECU (to check for problems with the vehicle control systems).

The map data is used by the program to choose the correct data to output (for controlling fueling, timing (& boost pressure on turbocharged/supercharged vehicles)

ECU Remapping only changes the Map Data to optimize the performance of the vehicle. Hence it is undetectable when a vehicle is checked with diagnostic software.
5. Will the Speed Limiter (VMAX) be removed ?
Speed Limiters (VMAX) are generally removed, but can be left in place if requested by customer.
6. What’s the difference between a Phase 1 (Generic Remap) and Phase 2 (Custom Remap) ?
Phase 1 (Generic Remap) – tuned on stock car (car without any power enhancing modifications (e.g. exhaust)). Power increases are what quoted in car datasheet in Database. ECU remapping done only once – this is a great option for drivers that don't wish to significantly modify other areas of their vehicle.

Phase 2 (Custom Remap) – tuned on a modified car (car with power enhancing modifications (e.g. gas-flowed cylinder head)). Power increases dependant on modifications. ECU remapping can done whenever any new power enhancing modifications are done.
7. How are vehicles tuned?
All tuning is done on the road using measuring equipment to check the performance parameters of the vehicle. These parameters are optimized to obtained the best power & drivability.
8. What power increase can I expect?
Normal Aspirated vehicles will have approxiamately 10% increase. Turbocharged vehicles will have approxiamately of 15% increase. Please refer to car database for more information.
9. Will fuel economy be affected?
Due to optimized efficiency of the vehicle engine, fuel economy at given speeds is improved after remapping. This is due to the vehicle making more torque than stock – hence less throttle opening required to achieve required speed after remapping.
10. Will my ECU have to be removed?
Depending on vehicle. Most new vehicles (from 1999 onwards) can be programmed via the OBD (Diagnostic) port using a serial programmer. Please refer to car database for more information.
11. Will my Rev limiter be removed?
FRC doesn’t remove RPM limiters, if required they are moved higher. Rev limiters are only changed on vehicles which need to be revved higher to obtain extra power (e.g. E46 M3 where RPM limiter moved from 7800 RPM to 8300 RPM).
12. Why not originally equipped by the manufacturer?
During the development of an automobile the manufacturers have to, in many respects, find compromises in terms of fuel efficiency, horsepower output, drivability and these days, the most important issue, exhaust emissions. Factors like fuel quality, maintenance, operational circumstances etc. as well as financial aspects i.e., insurance classifications, have to be taken under consideration. The manufacturers have to assure operational reliability for the final product worldwide, which means, that in most cases the actual engine potential is not reached.

Therefore the ignition, injection, boost, - etc. patterns programmed, are on the "safe side".

Furthermore almost all manufacturers offer mechanically identical or almost identical engines with varying horsepower output. The gain in output is mainly achieved by software changes. The stronger and more expensive version of a particular model car is often brought out on to the market 1-2 years later after the initial presentation (132 kW Golf 4 Gti). This is done to repeatedly draw the attention of customers, who already bought the previous model and might be willing to trade in and purchase the new release.

Our aim is, to significantly increase torque and horsepower output over the entire rpm range of the engine, especially on turbo charged engines. Here you will have the impression, after the optimization is done, to own an entirely different car or to have changed into the next higher vehicle class.
