Higher Octane

Post by Joshcornkid »

My 2017 Sport HB has a bit more HP than the EX/LX models because it runs on premium fuel.

My question is - Does the car already have, or does the Hondata FlashPro have the technology to recognize higher octane fuels (like 100 or 110 octane)?

Will running 100, or 110 Octane fuels get even more ponies out of that little turbo charged engine?

Yes, any of the 1.5 turbo engines will make more power on higher octane fuel. You can see this if you datalog the knock control channel - it will be lower with higher octane fuels.

Speaking of knock control...

I run 93 octane with my +6 tune and K control is mostly around .54 which to my understanding is as low as FlashPro goes. Why does the other go as low as .49 with 93 octane? Did Hondata decide to stick with .54 for safety? It just seems like you guys left a bunch of ponies on the table that could have increased the power on your tune.

The numbers are different but that may just indicate a difference in conversion. You'd have to use the Honda scan tool on each to see.
