I've changed my 750 RC injectors to ID 1000cc.
I use Hondata S300 and would like to know If there is a difference in the injectors voltage compensation?

I saw this scale on ID Website but it matches only static fuel pressure?



Thks

 

Yes there is a difference. Completely different injector. Input the dead time milliseconds/voltages into s300. It will be easier to tune and will run better with the proper voltages input into the scaler. Just add three decimal places to those numbers.

 

OK thank you
At idle, I have a fuel pressure set at 50 PSI with the vacuum line disconnected and 45 PSI when connected.
What are the good values?

Thks

 

If static pressure is 50 then use those those settings

 

OK, I tried and it's better when starting.

Do I need to change Fuel Trim?
I used this values when 750cc
Overall Fuel Trim: 0%
Cranking fuel: 20%
Thottle tip: 2%

 

Change from 750 to 1000cc and then retune it.

 

Correct, thank you, it works nice but I need to retune all the map
