    Ok, possibly 3 problems.  Firstly, Engine fan 2 is set to 0°C, this will have an effect even without a Engine fan 2 aux ouput assigned, so this means the idle fan step is always active.  I suggest change Engine fan 2 & 3 temperatures to 120°C, then they wont interfere.  Example below.

     
    Secondly, stepper motor idle valves only move quite slowly, so they dont often compensate well for fast load changes such as fan turning on.  It is best to use idle ignition control to help with this.  Some suggested settings below which should be a good starting point.
     
     
    Thirdly, your battery voltage drops from 14V to 11.8V in some cases when the fan turns on.  The lambda shows very lean at the same time, so this may indicate your injector deadtimes arent accurate.  This voltage drop may just be related to the RPM dropping so may fix itself if the adjustments above stabalise RPM.  But if battery voltage still drops a lot when fan turns on then it may suggest there is a bad ground somewhere.  You may need to experiment with injector deadtimes to improve lambda stability.

    The main problem I see is something wrong with your TPS sensor, when the engine is off it is sitting at zero correctly, but as soon as the engine starts the TPS signal becomes very noisy so you have lots of acceleration enrichment being added - about 80% extra fuel.  This could be a wiring problem or the sensor is faulty.  I suspect if you unplug it it will run better.
    Also I suspect your Lambda is not working correctly, it looks kind of believable up to about 36 seconds, but then it jumps up very lean but the injector PW didnot change?  So either that is a big air leak or the lambda is not working correctly.

    You have both AN Volt 1 and AN Volt 5 set to MAP sensor.  For Storm blue if you are using the internal MAP sensor it should be AN Volt 5, you need to turn AN Volt 1 off.  
    Because MAP is reading wrong (220Kpa with engine off), the ECU is applying MAP limit ignition cut (boost cut).
    After turning off AN Volt 1 please confirm MAP reads same as BAP with engine not running.
