Not need pass for this, if you download original file and with the offests posted you cannot figure out how to change for any km/h... I think you missed the job/hobby ;) FYI this ecu normally use 16bit not 8 ;)

:D
why don't you try to find such bytes yourself ?
all what you know is other's research
but real knowledge is to find without any help at all

it's more easy to find the bytes that limit the speed
as find the byte on/off for speedlimitation

I feel the confusion when I wrote "now" I meant "how". My English is not very good.
I would like to be able to find the bit, just ask for help.
how to convert limiter bit I tried to reason it out for myself

did you tested to change the byte i told higher in message put it to 5000 in stead of 9000 then if it's the good adress the car limit to 50 kmh ...

not yet, the vehicle is a delivery company and I have only 2 hours every 3 days. I have only the flash, if not let me remove the ecu ...
is a fiat ducato unlimited ecu with this model and was investigating before giving a response to the client.

in some case it's possible to loose car config
injector codes
cruise control
so it's better to do read bdm and be sure you can restore the situation if obd erase the options

ernene

But eprom can't write by obd2?

201031 this is the eprom of a fiat ducato, if I believed as limited to 300 no?

yes 9000 is 90km/h, just set to 30000 and you will never have limitation.
and check cheksum before rewriting
