The owner of this 2003 Volkswagen Beetle came to us after the previous garage looking at the car couldn’t find the problem.
The car was showing an EPC light in the dashboard. We immediately knew that this was related to a supply issue on the ECU (Engine Control Unit). We took about removing the interior panels for us to gain access to the ECU and its wiring loom.
Today we remapped a V10 TDI engine! The customer wanted better driveability, performance and economy.
We downloaded the standard map on the ECU (Engine Control Unit) or should we say ECU’s! As this car like more and more these days have dual ECU’s to control all of the technology onboard. After we downloaded the map we set about making fine adjustments to the air flow and fuel injected to allow the engine to produce more power, more efficiently and in a safe manner.
A bit of background around the engine in this car:
It is a 5.0 liter V10 Twin Turbo Diesel, features 309bhp and 553 lb/ft torque.
We did an initial power run to see how much power this vehicle has. The figures were:
322bhp and 520 lb/ft torque.
After our remap we were suprised at the results acheived:
409bhp and 670 lb/ft torque.
The owner of this Porsche 911 came to see us after a recommendation. The previous garage had stripped down the engine and were unable to take on the task required.
As the engine was already stripped down we were able to immediately inspect the cylinder walls and determine the issue. The cylinder walls on the naturally aspirated Porsche engines are Nickel Sealed Aluminium and are known to suffer from cylinder pick-up. This is where as the piston is moving up and down inside the cylinder it makes enough contact to gradually strip away this Nickel Seal, leading to loss of compression.
After we spoke to the customer it was decided that to replace the cylinder block it would be worthwhile in fitting the existing cylinder block with brand new Steel Liners. This would ensure that in the future this enginer would never suffer the same issue.
