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.

thanks, I will look at it, the configuration of the injectors is correct to my blue storm?

 

This is not my configuration, but would it be the correct one working at 1/2 cycle?

You would be best to set active drives to Inj1-2 and injection rate to 1 cycle for your setup, but these are not related to your "unstable idle".

Sería mejor establecer las unidades activas a Inj1-2 y la tasa de inyección a 1 ciclo para su configuración, pero estos no están relacionados con su "inactivo inestable".

hola haciendo bobinas de prueba, tengo señal en el tps. He conectado sólo bobina no bujía y tengo señal en TPS

the manual recommends a condenser, I don't have it

A condensor is generally to reduce magnetic loop noise that is generated at high load.  I dont think this is your problem when doing an ign test as spark voltage will be very low.

If your TPS signal gets noisy when doing an ignition test then it would suggest you have a wiring problem.  My guess would be there is either a poor ground connection between ECU and engine block or you have sensor ground connected to engine/chassis somewhere.

Un condensador es generalmente para reducir el ruido del bucle magnético que se genera a alta carga. No creo que este sea su problema al hacer una prueba de encendido como voltaje de chispa será muy bajo.

Si su señal TPS se vuelve ruidoso al hacer una prueba de encendido, entonces sugeriría que tiene un problema de cableado. Mi suposición sería que hay una mala conexión a tierra entre la ECU y el bloque del motor o usted tiene el sensor tierra conectado al motor / chasis en algún lugar.

Tenías razón. Tengo problemas de masa. ya resuelto. ahora ves la diferencia en el registro
