Find cranking injection/T?C? Renault Espace 2.0T ECU S2000RPMT

[kitnoos2002]

Hello,
This vehicle, which is carburizing at E85, is experiencing progressive difficulties in cold starting, as the temperature drops below 20 degrees C.

Could you help me to find where are the cranking injection values, based on temperature?
Thank you !

Renault Espace 2004 2.0T 163CV
ECU : Sagem S2000RPMT
HW : 8200279458
SW : 8200352155

Does anyone have a damos compatible with my file?
Thank you !

There are two address C0FB , C10C - 17x1 factor 16 = RPM. Temp waher from -40 to 120 C , step 10deg.

Thank you very much but I'm looking for Fuel Injection VS Temperature during start.
I think you gave me Idle RPM VS Temperature.

You don't have any options with this worse ECU. Just increase idle at low temperatures. Here revolutions are the result of the amount of fuel injected.

Hm, this is not a diesel car...
Here revolutions mostly are result of the intake air amount.
Actually the man asking for enrichment the start dose of the fuel.
If you have a damos for this ECU...
Regards!

I found a damos ("2A4200.A2L") for a very close ECU (S2000 Renault Espace).
This damos don't work with my software ID !

But if I open the good file compatible with this damos, I can see that the values are like it :

I think I found what you're looking for. Address AA5B 17x1 , faktor 0,064 (ms). Excise temperatur C from -40 to 120 C , step 10 deg

Thank you for your informations !
I will try, but you found at address 0xAA5B : Ctp_tco_dec_sta_ti.
I'm not sure but I think "dec" is Fuel decrementation just after start :



Maybe I'm wrong but I think the curve must be like this :
OR


With your informations, I could see just below, at address 0xAA7E (17x1), there is a curve that looks like cranking fuel correction factor :


But without compatible damos, I can not be certain that this is the curve I'm looking for.
What do you think ?

Hello,

Did you find damos file ?

Which software did you use to upload ecu file ?
I found method with galleto and boot method.
I search easier solution.

Thanks
Aymeric

I use also Galletto v54 . Not damos , not easear solution for flashing.
