Hondata

I noticed on this new update.

Injectors: increase fuel pressure to reduce the injector duty cycle.

I have a 2020 civic si with
27Won turbo inlet pipe
PRL CAI Race

I've been running base tune +6 psi. runs perfect

1st question is, if I have a stock fuel system can I still run this "injectors" in the modification? If so, will this be safe?

2nd Will this be ok with the Hondata base tune +6 or do I need to run +9?

This is 4th gear to 5th gear pull.

Don't know much about tuning. But can Hondata representative check out this
datalog and see if it's ok.

1. It is safe, but on pump gas and a stock turbo there probably is no need to run higher fuel pressure.
2. Either is ok.

Your datalogs show the lambda, trims and fuel pressure as good. Knock control is low and there is a fair amount of knock retard, so higher octane fuel would be your path to more power.
