Took out the engine in my Rx7-96 to paint engine compartment.
When I now built back everything as it has become a problem.
The car runs great if you gas up slowly.
But as soon as it comes over 0PSI so it begin to boost cut and misfire.
Think the car is in limp mode, have checked the diagnostic flash and them showing Intakr Air Thermosensor and 02 Sensor.
but i have Ohms measured everything and checked all cables so everything works but car would not go out of limp mode when I try to reset it.
Thinking about it may be that the ECU has broken in some way?
Or does anyone know what it could be if you can't get out of limp mode?
All donors work so it's strange that it stays in limp mode.
Thinking of switching to Apexi FC, just want to know if it´s the ECU which is broken.
Does anyone have any ideas on what it could be otherwise?

check the intake system,especially the piping.
These cars are known to blow the piping(coupler) off the turbos and cause a "no boost situation"

Sounds like the classic vacuum line coming off the Manifold Absolute Pressure sensor.

Won't throw a code as its working fine measuring your engine bay pressure instead of intake pressure.

Sounds like you will also need to fix the intake air temp sensor and o2 sensor.

I test another pressure sensor and air temp and ECU. But still not working..
