Porsche 992 JB4 installation tips?
Has anyone installed the JB4 into the 992? I have a convertible and while the TMAP sensor is easy enough to get to, the MAP sensor on the intake manifold is buried deep into the engine bay. I have rather slender hands but there is no way I can get my hand in deep enough to access the MAP sensor let alone wiggle it out with the plastic locking mechanism. I cannot even touch this thing. Any ideas out there?

I was able to installed the map sensor after removing the rear bumper and ECU.

If you unhook the ECU harness, that will leave you space to reach and undo the manifold sensor.

Gigantic struggle... and months later. The JB4 is in. It's worth it. Performance I can feel.

JB4 not working Map 3 Map 4
JB4 on 992 not working for Map 3 Map 4 properly. Car seems to be shifting abruptly and too often with the PDK. JB4 cannot record logs. The phone app crashes on "Start Logging".

Map1/2 works just fine. OBD is plugged in and I can see AFR/RPM etc. data.

Any ideas here BMS team?

Can you try to get us a log and post it up on map 3?
