Anyone have experience with the 10th Gen Civic and the 1.5T motor?

I'm obviously thinking about chipping/flashing it but curious what's a save amount of power to get out of it?

I believe from what I've read on Hondata and Ktuner... they were able to squeeze around 220-230hp from the standard 1.5T engine without damage to the transmission (in CVT models). There's a lot of available info online for Hondata or Ktuner standard tune maps that they tested and perfected so as not to reduce reliability to the car.

Thanks. So it's less about the engine and more about transmission issues. Those CVTs aren't made for performance.

Is this also true for the Si models?

Si models (and models with manual transmissions) can handle more torque than the CVTs can. But Hondata and Ktuner also found ways to map the gearing on the CVT so that it builds progressively rather than being instant off the line, this does a lot to save stress to the CVT as that seems to be where most of the issue lies. The CVT is fine once in motion, its the initial launch that causes the most stress, so they found ways to work around it. I don't fully remember what Torque rating they landed on... surprisingly don't think the CVT vs Manual was far off... just different torque spread. I think they managed to get the Si tune close to 300 horses, if I remember correctly.

For the cost of the module, and maybe some different tires a standard turbo civic can easily outgun a factory Si... and a tuned Si can holds it's own against a factory Type R.

I'll also note that those systems also make it possible to install multiple maps and ways to toggle them, such as making the ECO button switch to a new map, and the S setting on the transmission also changing the maps. So it's possible to keep the factory tune setting in place, and have the higher output tune on demand with a button or gear shift, which is pretty cool I think.

Thanks. Initial stress is always an issue. I remember back when the WRX first came out everyone complained about weak manual transmissions. The reality is, they were all used to FWD/RWD cars that just let the slip come out at the tires. With a WRX, or any AWD car, the give happens at a different friction point.

And that button idea is amazing. (Heading to YouTube to see if I can find a video of that in action).

DSPORT Magazine was able to get between 18.55 psi and 25.56 psi on the turbo with different tests.

We’re impressed with the performance capability of the new turbo Civic. Straight from the showroom floor, this iteration of the Civic easily beats all previous generations making it even more rewarding to modify...

Here's some early info on the Hondata tuning for the new Civic turbo

 

[18Hatch]

I have an ‘18 hatch with a Ktuner. With the 21psi tune, the clutch will slip in 5th and 6th when accelerating up from cruising speeds (knowing this I always shift down). I’ve even noticed the clutch will slip in 4th if accelerating hard from a 30 mph speed zone IF I have a passenger. It doesn’t slip if it’s just me in the car. It’s interesting that slippage is sensitive to a 150lb difference.
For passing, if I want to overtake someone who is doing <55 mph in a 55 mph zone, I’ll go to 4th and then drop to 3rd when I make the pass. This gets the rpms up in the 4,500 rpm sweet spot. I absolutely love how it pulls up to redline. Rowing through gears, 100mph comes pretty fast.

Welcome to the forum.
Are you getting a new Civic hatch (or sedan) eventually?

Thanks for the welcome. Based on my experience so far, I am happy with my Civic and would consider buying another one in the future. It currently has 50,000 miles on it and hope to add a couple hundred thousand more. Any replacement is years away (hopefully).
