Nitro X - centralina per FJR

Clicca qui


Qualcuno ha idea di come funziona? Mi sembra un po' un pacco, ma quasi quasi 30 euro me li gioco.

Su come funziona non dicono nulla. Bisognerebbe leggere le istruzioni che vengono allegate in inglese. Mi chiedo come possa essere installata in soli 5 minuti applicandola semplicemente sul serbatoio con gli appositi adesivi e/o magnete.
Mi fa paura che dichiarino che ovviamente il prodotto è da intendersi solo ad uso in circuito chiuso e ad uso "racing" e che, proprio per questo motivo, non rispondono degli eventuali danni causati dal suo utilizzo a sè stessi ad altri o al veicolo! Quindi nessuna garanzia e di qualsiasi tipo.
Modifiche alle centraline le farei solo se venissero installati i file originali della fabbrica e da personale qualificato.
Conclusione: sembra un pacco pure a me... :wink:

non ci credo neanche io ciao

Ho mandato un email. Se dovessi ricevere istruzioni o data sheet, le pubblico qui.

Ecco le istruzioni che ho ricevuto

FITTING INSTRUCTIONS

1.DISCONNECT THE BATTERY   ****VERY IMPORTANT****

(when connected back after the chip installation the ECU will run a Test Programme that will accept the newly plugged in chip and accept the new remapping commands from the programme you select).For latest models that run a diagnostic test every time you switch on,the process might not be necessary.

2. Locate the Inlet Air Temperature sensor on the filterbox under the tank.

3.The IAT  sensors  usually have 2 wires.If though yours has 4 wires then you need the 2 signal wires and not the 2 power wires. You can use an electrical multimeter to find that out or if in doubt please advise a bike electrician/mechanic.

4.Remove the connector from the sensor trying not to break the safety clip that most connectors have.

5.Insert  the legs of the NitroX chip into the connector contact slots.One leg in each slot.It doesn`t matter which way round the chip legs are connected.Just make sure that the legs are in contact with the metal clips inside the slots and that they will remain in contact while the vehicle is running and there will be a lot of vibration in the engine area.

6.At this point the connector can`t be plugged back to the sensor so it should be tied in order to prevent it from moving freely.Also to make sure that the chip won’t be disconnected and that everything remains in place the use of  some electrical tape would be a good idea.The chip on its bottom has a sticker that can help you stick the device on a clean surface ( e.g. the tank) also you can place it on metallic surfaces as the bottom of the device is magnetic.

7.Reconnect the battery and test drive your bike.You’ll be able to feel the difference immediately,though your bike ECU will take some learning time to make micro adjustments in order to reach maximum performance for the program you have selected.This learning period lasts about 100 miles (plus or minus 50 miles depending on the ECU type and model)

 

If for some reason your vehicle behaves problematically after the installation of the chip,then you must remove it and connect back the OEM IAT sensor.It is rather uncommon but some ECU units have a safety programme that might not accept the chip remapping commands.But that’s not a problem as the process is totally reversible so when the chip is disconnected the ECU returns to the original programme .

Nitro X©    Programming  instructions

 

To set the mapping programmes place the dip switches (of the desired programme combination) in “ON” position.The numbers 1,2,3,4 in the following combinations represent the matching dip switches on the NitroX chip placed in “ON” position.

 

a)      1+2+3+4 switched on   = 5     %

b)      1+2+3 switched on       = 10   %

c)      1+2+4 switched on       = 15   %

d)      1+3+4 switched on       = 20   %

e)      2+3+4 switched on       = 25   %

f)        1+2 switched on           = 30   %

g)      1+3 switched on           = 35   %

h)      1+4 switched on           = 40   %

i)        2+3 switched on           = 45   %

j)        2+4 switched on           = 50   %

k)      3+4 switched on           = 60   %

l)        1 switched on               = 70   %

m)    2 switched on               = 80   %

n)      3 switched on               = 90   %

o)      4 switched on               = 100 %

 

 

 

The  performance percentage in the list above doesn’t necessarily match the performance response of  your bike.The performance values given above represent only the performance value increase of the chip given by the manufacturer.

The starting value of your bike might not necessarily be the same as of the chip.That means that  zero point in your bike might be between “b” and “f ” programme .So all programmes below your bike zero point will work as fuel economy programmes BUT will decrease your bike horsepower.

To find out the best programme for you,you  should start test riding your bike using different programmes starting from the lowest  one,skipping a couple every time until you reach a point of satisfactory performance.Then you can test one programme up or down to decide which is the best for you.  


 

In breve, da quello che si capisce, la centralina imbroglia l'ECU facendogli credere che l'aria ha una temperatura più bassa o più alta di quella reale e quindi costringendo l'ECU a correggere di conseguenza.
Credo che ci sia un'effetto collaterale, e cioè quello che la temperatura dell'aria segnata sul display a questo punto sarà sempre sbagliata.

Leggendo la descrizione delle "regolazioni", si vede bene che tutto quel che fa è aumentare di un certa percentuale l'influenza della correzione in modo "piatto", senza nessuna variazione che dipenda dall'apertura dell'acceleratore o del numero di giri, ecc.
Una gran ciofeca, IMHO...
