Air-con vs. Renault Sport ECU

[BluePony]

Hello!

First, sorry for my bad english speaking, Im italian.

I have a problem: Renault Service cant help me.

In my Clio 172 (second series, 2003) the air con does not work perhaps since I had installed a new ECU Gr.N from Renault Sport. The code of ECU (7711129506) is right for my engine (F4R-736). I have already replaced the pressure valve and recharged the clima.

At min rpm of the engine, the compressor work well: the temperature of the air out is about 5°C. When i exceed 2500 rpm (in motion) the compressor turn off and the air becomes warm (16°C).

The problem can be caused from the ECU? Someone of you has had the same disadvantage?

Many thanks to all!

Maury

the aircon compressor is switched off under full load on the normal ecu. maybe the group n ecu changes these parameters slightly and switches off the aircon early for some reason.

I know that not all ECU RS on the Clio RS Phase 2 cause the problem.

Two my friends have this, but other four have perfect functioning of clima. So, many factors will cause this...

I suppose: the ECU have tree maps for partial load, and one map for full load. Maybe my ECU is permanently in full lod map?? In this case, probably might reset the ECU...?

Bye, thanks!
