Hello. I had change my injectors from 310cc stock to 410cc denso injector. And i set the injector size to 410cc already , i found that my engine was very difficult to start specially at normal coolant temp. (>60 ). What can i set on krpo to fix this problem? Thanks you

Have you set the correct dead times for the new injectors?

In fact no, where can i find the suitable dead time for my new injector?

You will have to look for the spec sheet to those injectors from the manufacturer.

Use the drop down list and select the RDX 440cc injector

I have set the dead times already, but still difficult to start . What can i do ?

It is something other than the injector dead times. A calibration and datalog would be helpful.

Please have a look. I found my engine was hard to restart while turn off the engine about 30 minutes (coolant temp >40degree) . But the engine was easy to start every first start in the morning.

Your battery / charging system is no good. Battery voltage is falling to 8.5V when cranking; it should be at least 10V. When the engine starts the voltage is only coming up to 12.1V; normal is 13.8-14.5V

Hi, review on the datalog . The cranking ignition is [-10] , it is normal? Thank you
