It’s been a while since I last posted. I just wanted to thank Scott Slauson from Softronic for tuning my conversion.
The car is a 2014 Cayman with a 3.8L with upgraded cooling, brakes and PSS10 suspension. It has the larger ipd plenum and 82 mm throttle. Lowered.
This is my third conversion. I previously did a 2000 Boxster and a 2005 Boxster.
I did the work myself and worked with another tuner to reprogram the DME. While I know the tuner worked hard, we were never able to get the cold idle correct. Until the O2 sensors warmed up and operated closed loop, the car would miss because it thought it was the 2.7L.
I shipped the car to Scott and he figured it out. Cold starts are much better. The car runs really strong.
If anyone needs to ask any questions about this DIY, let me know.
I’ll post some pictures ASAP
