Project Civic X — Bone Stock on High Octane

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

This doesn’t take a whole lot of explanation — we picked up as much as 60 ft.lbs. of torque more on the high octane fuel — and almost as much as 40-50whp more through the curve.

How’s this stack up against completely stock? Here you go — something like 80-90 ft.lbs. of torque more over stock.

 

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!

Versus a bolt on 8th gen.

 

Versus a bolt on (RBC swap) 9th gen.

 

 

Thoughts?

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).
