No the actual rev limiter whilst parked, mine hits 4,000 RPM and max's out, how do i remove the limiter so it reaches 7-8k?

Is there anyway to remove the rev limiter on a 1.4 TSI Golf with this app??? out of curiosity No. Not even VCDS, VAGCOM or OBDeleven can change this feature. This is set in the EEPROM of BOTH the ECU and Mechatronics unit, but not accessible by our OBD tools. To change this, the car would first have to be re-flashed by tuning solutions such as APR, Revotechnik, Eurodyne etc. Then at that point, these tools can then change the RPM limiter. The reason for this limiter is to protect the clutches in the DSG (as the vehicle isn't truly in "neutral" when the DSG is placed in Park or Neutral). In "Park" or "Neutral"both the "2nd" and "Reverse" gear is pre-selected in anticipation of what the driver is going to select next (for the 6-speed DSG since they are on 2 different input shafts). It is easy for the car to shift from second to first gear when the car is placed in DRIVE. NB: for the 7-speed DSG, it is "1st" and "reverse" gear that is preselected since it is 3 input shafts and the gears are better arranged. If the RPM limit was increased in the preselection phase, then the clutches would generate too much heat and cause damage to the clutch packs. This RPM limit is also set to prevent drivers from flooring the accelerator in "Neutral" then dropping the gearstick in DRIVE which would then cause instant destruction to the DSG (not the engine) if you were allowed to freely floor it to the red-line. Setting the RPM limit at ~4,000 would only cause the engine to bog down since the 1.4 liter doesn't have that much torque anyway causing no damage to the DSG). Obviously setting this limit in a manual car is just to protect the engine (since there is no load applied). In conclusion: if you want to make this destructive change to your car, you would have to get the car flashed. The problem is that there are very few tuning solutions for the 1.4 TSI on the basis that it isn't a performance oriented engine and doesn't improve drastically with bolt-ons or a re-flash. |
