Just days after tuning the Civic EX-T bone stock on 87 octane I’ve managed to get the tank low enough for some high octane testing — still completely stock. Wasn’t an easy task running the tank low when it gets 40mpg on the highway!
But here goes… the results are FANTASTIC!
High Octane Vs 87 Octane
Versus 8th and 9th Gen Si
Since we were having a bit of fun comparing the results of the Civic X vs the previous generation Si — might as well keep going!
I could of actually made more power (especially more torque) on the Civic X on the high octane fuel — but I was cut off at the knees by the software currently available to tune these cars. So take these results as “software” limited. It is very early in the life of these cars and once we get more ECU development for the platform a lot more potential will be unlocked.
And keep in mind — this is still BONE STOCK. Time will tell what a few bolt ons will do (especially a downpipe).
