Hi Everybody
Without Prejudice
Last week I had a chance to run a 718 Cayman GT4 on a dyno , and look closely at the GPF information it provided.
When looking at the information, it shows more aligned actual exhaust GPF temperatures, not calculated, as in the 2.0 and 2.5 vehicles.
To back this up, these cars have a exhaust temperature sensor fitted into each GPF.
Our cars don't have this sensor, could this be contributing to our problem.
After all the engine ECU needs a good accurate exhaust temperature to start a regeneration to burn this soot off and leave a small deposit of Ash in the filter.
I have always thought that if these cars do not carry out a good temperature regeneration, then that could lead to excessive ash deposits.
If I put damp wood in my wood burner and its not hot enough, I get lots of Ash.
All this is providing, these GPF filters are indeed blocked at 100%.
Enclose photo of the exhaust temperature sensor fitted to the GT4.
I will post out more information of the tunning company who invited me to check their car out in a future post.
These guys specialise in Porsche power upgrades.
