Honda Civic 2016+ turbo with tune from Hondata will have more power than the Si

from https://ca.motor1.com/news/144327/honda ... sts-power/

- manual, turbocharged Civic boost increased by 9 PSI, and adds a total 35 peak hp and 60 peak pound-feet of torque
- CVT-equipped, an extra three to six PSI, the latter making it good for 214 hp and 220 lb-ft of torque.
- tune adds no-lift shifting capabilities, and pending CARB approval, it will even be able to pass emissions testing in California
- whichever option will surpasses the Civic Si’s meager 205 hp and 192 lb-ft of torque
- cost $700 (approx. $950 CAD), Hondata dealer $350 (approx $480 CAD)

Anyone consider tuning their vehicle?

Why even make the comparison?
When you add a mod (in this case a tune), it is no longer an even playing field.

So that people can make an informed purchasing decision?

That's not bad. Too easy to make cheap power with turbos and tune. I wonder how much hondata can make out of the Si. Probably not too much more since same engine.

Real question would be how much they can make out of Type R. Hope they push 400hp lol

Considering type R is fwd I see no reason to increase hp/tq numbers, imo its already plenty for that platform.

With most factory FI vehicles, the factory tune is on the conservative side, but should be for long term reliability.
At least factory tunes are backed by warranty.

I wish there was actually some way to do this with more cars. It's such a neat thing.
RFD is love. RFD is life. I wish I had an RFDer for a wife.

Just trying to understand how this works... It's there anything that would prevent a couple of friends with Civics 1.5 turbo to buy one flash tool and flash all their respective cars?
Also, what's the impact on the factory warranty? Can one easily "unflash" before going for dealer service?

If its anything like my AccessPort for my Ford (also avaliable for Subaru and Mitsubishi I believe), the device is locked to a car once its flashed. Once you unflash it from the original car, then you can flash a second car, and the device will be locked to the 2nd car.

As for factory warranty, well, its a gray area. Once you unflash your car, most dealer usually has no way to detect it, but the manufacturer does have ways to look at the data, but that usually requires the car to be at HQ/factory.


I used to unflash my car before servicing, but I've been lazy and haven't done so in years haha.

You can purchase a module that plugs into the OBD port and select the different programs based on fuel type.
When you bring it in for service, you load the stock tune, unplug and you're good to go.
While a tech can't see what the actual tune was, the ECU does have a counter and will record it.

+1

Also have fun trying to get warranty for the car... I imagine the CVT wasn't designed for the extra power

Can't speak for Honda, but VW/Audi are very good at catching ECU tunes and the computer will automatically flag your car. It used to be that dealerships/service techs could opt to ignore it and not report the tune, but now it's not possible. Flashes/ECU tunes won't automatically void your entire warranty, but if you have any powertrain related issue they'll likely make the case that the increased power was the culprit and deny your claim. They can't however, refuse to fix your interior trim issue because it's completely unrelated.

It's commonly available for turbocharged cars, which are becoming more common (the new normal, really). Some are designed to plug into OBD-II port and get removed before servicing.


In other shocking news, an Si with a tune will end up quicker than a non-Si with a tune. It'll also have the helical Limited Slip Differential to put that power down.
