E85 issues

Post by Ktm125er »

2015 civic si. I got full race catted exhaust and cat back. Dw300 pump with 550 injectors. Stock intake stuff. Nothing done to the motor. Siri moto flex fuel kit
Basic info I’d think everyone would need lol. Everything seems to read correctly. Reads the percent correctly for the ethanol. But it seems to not compensate the afr correctly. It’s at the same afr as e10. Idk if there’s something I’m missing. It’s runs at 12ish when I read up on things they say it should be under 10 maybe even 9. Am I overthinking it or something is wrong. Maybe to big injectors? Running the Hondata tune with the injector size changed and everything else small done to it

It will need to be tuned as your fuel trims are quite high.

Yeah probably. I was hoping to wait till I got everything done but I did find out that I need to add injector time stuff and that helped out with the trims
