Hondata Turns 2018 Honda Accord 2.0T Into a Civic Type R-Beater for $695
Hondata claims impressive power gains
The redesigned 2018 Honda Accord is quick, hitting 60 mph in a Motor Trend-tested 5.7 seconds with Honda's new 10-speed automatic and a 2.0-liter turbo-four, a detuned version of the engine found in the new Civic Type R, that makes 252 hp and 273 lb-ft of torque. Thanks to the Honda tuners at Hondata, more horsepower and torque can be extracted from the turbocharged engine in different stages.
Using Hondata's FlashPro device, the company claims gains of between 10-40 hp and has posted a dyno sheet of the Stage 1 tune that shows increases of about 10 hp and roughly 40 lb-ft. When Hondata put a factory Accord 2.0T on a dyno (see the video below), they recorded a baseline of 266 hp and 292 lb-ft to the wheels, well above Honda's advertised power ratings. The estimated gains are based on those dyno numbers, so that puts the Stage 1 reflashed Accord at 276 hp and a healthy 332 lb-ft to the wheels using California's 91 octane gas. That's already more torque than the Civic Type R makes (306-hp and 295 lb-ft).
If Hondata was able to get 10 hp and 40 lb-ft from this tune, imagine the torque increase from the tune that gets you 40 hp. Well, we don't have to imagine as Hondata posted a video of the dyno run with the Stage 2 tune showing peak torque of 375.8 lb-ft-a gain of about 80 lb-ft over Hondata's baseline figure. Additionally, the Stage 2 reflash adds 50-55 hp in the middle of the power band, which is said to dramatically affect the driving experience.
The FlashPro only works on model-year 2018 or newer Accords with the turbo 2.0-liter engine and connects to the OBDII port without any ECU modification, but you will need a computer with a USB 2.0 connection. The FlashPro device retails for $695, and appears to enable both Stage 1 and Stage 2 tunes. However, it's unclear if any additional aftermarket parts are required for either reflash.
Honda is slowly phasing out its naturally aspirated engines in favor of turbocharged engines. While Honda purists may cry foul over this, many enthusiasts are taking advantage of the impressive power gains that come from tuning a turbocharged engine. Check out the numbers Hondata got from the Accord's 2.0-liter turbo-four in the video below, and also check out their baseline run to see how much power the new engine really makes.

Tuning the Honda Accord
"Tuning guide to the best Honda Accord modifications."
Tuning the Honda accord can make for a fun and interesting project.
The Honda Accord was first launched in 1976 ensuring lots of fans, and plenty of tuning parts are around for it.
Later models saw a Honda / Rover collaboration which ended in 1993 when the Rover 600 was launched.
There were a number of different engine choices ranging from the a 1.8 which produce 115 BHP to the desirable 2.2 V VTEC and 2.3.
On paper the 2.3 would appear to be the engine to choose but in reality the 2.2 VTEC with its high revving characteristics is the best model to go for by far.
The model range was revised in 1998 and a Type R model was introduced using the 2.2 litre VTEC engine.
For car of its size it was sprightly and could reach 60 mph in a little over 7 seconds.
The 3 litre V6 engine also offers plenty of scope to the tuner which produces 200 brake horsepower in its standard form.
The 1998 models are all noted for their impeccable motorway manners and superb road holding ability thanks to the superb chassis and suspension design.
Engine swaps are popular on the Accord, and we have covered the following engines in detail.
In 2003 the range was futher revised but for some reason the UK had a choice of just two engines the 2 l and 2.4 litre.
The JDM (Japanese Domestic Market) had the Type R version which still today is regarded by many to be the best front wheel drive car currently available. This makes the JDM Honda accord 2003 on a popular choice with importers.
Although the Accord is aimed at the executive luxury market there is a good selection of aftermarket parts for those wishing to tune up their Honda Accord. The Type R models have very good standard mechanicals and it is a challenge to upgrade the air intake or exhaust system for better performing ones.
Accord Handling/Suspension upgrades
Improving the handling for loads of people first priority in your Accord tuning project.
Good suspension tweaks that often enhance handling for the Accord include a couple of degrees negative camber and 1-1.5 degrees of toe in or out on the front wheels. Toe in for stability, or Toe out to improve cornering. It would also pay to improve the brakes, by adding larger discs and or higher friction pads..
Drop the car by as much as 27mm - 36 mm. and fit motorsport grade stiffer dampers, bigger drops will need other modifications in most instances.
Top end power should be your overall aim on the Accord with a nice fat peak torque band.
Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.
Best power mods for Honda Accord engines.
This list of the stages and sports mods are usually carried out by our members, decide how far you wish to go in your tuning project before you get started.
Getting the best sports upgrades for your planned usage of the car is a time and money saver. Stage 3 motor sport parts just won't work well on the road and will make the car undrivable.
Typical stage 1 mods often include: Remap, Sports exhaust, Suspension upgrade (drop 27mm - 36 mm.), Alloy wheels, Lighter flywheel, Panel air filter.
Typical stage 2 mods often include: high flow fuel injector, Fast road cam, Ported and polished head, Power/Sport clutch, fuel pump upgrades.
Typical stage 3 mods often include: Adding or upgrading forced induction (turbo/supercharger), Sports gearbox, Competition cam, Engine balancing, Internal engine upgrades (pistons/head/valves).
You should keep as much low end power as you can and aim for a wide power band across the rev range rather than a narrow top end power hike.
In this article we shall give your a good starting base to the best modifications for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance part. A fast road camshaft typically is one of the best NASP power mods you can do with a single part fitted to your engine.
The exhaust and intake flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car challenging to drive in traffic. You'd need to follow a camshaft upgrade with other mods and finish with a performance chip for the best performance gains.
You will need to ensure that the engine is not starved of fuel so will need to pay attention to the fuelling.
Most power losses, and erratic idling after uprated kits are done can usually be traced to fuelling or timing issues. To get sufficient fuel you may need to increase the injectors on your engine.
A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this if your injectors are demanding more fuel.
Intake and Exhaust Tuning.
Now we move on to the intake and exhaust and ensure proper flow through the engine. Contrary to popular belief there is often a small power gain reached by fitting an induction kit, they only become beneficial and are recommended after you raise the engines power to the point where the standard air intake box cannot cope!
All other models in the range will benefit from a good quality stainless steel sports exhaust, sports cat and cold air induction kit. Gas flowing the head is also recommended (again the Type R models are a already well machined and optimized).
Induction kits can work well on turbo engines and larger engines (if supplied with a suitable cold air feed or air box), generally though we'd just recommend for Accord engines you should just fit a high performance panel air filter preferably made from cotton.
Sports exhausts will certainly help air flow from the engine but do not go too large or you could very well end up with a reduced flow rate. So generally speaking, keep to 1.5 to 2.5 inches as a rule of thumb.
Head work including a gas flow (ported and polished) and 3 or 5 angle valve job will really help to release the potential of the engine. A good fast road performance clutch will help to keep that power going where it should. Never make false economies or ask a standard clutch to cope. The best mods that we recommend for your Accord are Remapping or piggy back ecu, fast road cam and air intake and exhaust.
Remaps offer impressive power gains on all turbo charged cars. On NASP engines the benefits are doubtful. However a remapped ECU on a NASP engine will help unleash the potential if you have done a lot of mods.
We've also seen some tuners experimenting with twincharged applications and making some seriously high power hikes.
Adding forced induction will see phenomenal power gains but this is usually too expensive to be cost effective. It is usually cheaper to bolt on a supercharger than it is to install a turbo. Turbos give boost in increasing proportion to rising engine speed and this can make mapping difficult.
The nice directly proportional boost and rpm characteristics of the supercharger make them simpler to map. Alternatively you could add water injection to minimise knock.
Alloy wheel upgrades.
As alloy wheels are less heavy they improve performance and they can help to cool the brake disks. Don't forget that your choice of rubber greatly affects your cars grip and handling. It is not worth compromising performance with cheap tyres when you can buy directional tread pattern performance tires.
The drawback to large rims on your Accord is that you're altering your effective final drive ratio so this will have a detrimental effect on performance and acceleration.
Due to this we would advise sticking to a maximum wheel size of 18 inches, although we know some of our members have gone larger than this with no problems.

Accord 2.0T Extended Testing
2018 Accord Extended Testing
by Derek Robinson – http://www.Innovative-Motorworks.com
2018 brings some major changes to the Honda Accord. In recent generations, a naturally aspirated four cylinder K24 engine was the standard engine option, while variations of the mighty J-Series V6 provided a healthy bump in grunt to one of Honda’s most awarded platforms. Now, a 1.5 liter turbo engine is standard, and a variant of the Civic Type R’s venerable 2.0 liter turbocharged powerplant motivates the car as an upgraded driveline. Over the course of the last year we’ve grown quite fond of the 1.5 turbo engine’s abilities, so we were very excited to begin scratching the surface of the capabilities of the “everyman’s” 2.0 turbo K20C engine.
This tester was graciously provided to us in a time when these cars are still fairly hard to find. It is a 2018 Honda Accord Sport 2.0T model, fitted with a six speed manual transmission, with 2,000 miles on the clock.
Testing began with the stock ECU calibration; both on 87 octane fuel (which is realistically what 99% of buyers outside of the enthusiast market will end up using, undoubtedly), and with 93 octane fuel (for those of us that understand the fun of fuel quality).
This thing is a stump puller from as low as 1,500rpm. The turbo responds almost instantly to throttle input when loaded, as evidenced by the start of the run’s massive torque figure. As you can see, the difference from 87oct to 93oct on the stock tune file is a result of the different knock control levels present (the ECU pulling ignition advance out). Overall? Very stout starting point for an engine that’s 1.5 liters smaller than the outgoing ‘king of the hill’ J35 V6 engine.
Next, we wanted to test the KTuner “Stage 1” calibration, which makes numerous drivability, fueling and boost pressure changes.
Big gains from the “Stage 1” tune, and a much flatter torque curve. over stock. The midrange is SUPER healthy over the stock tune file. This calibration also retains the “ECON” mode, and lowers boost levels to stock for when you want to be “less race car.”
Next up? The whole reason we tested; to aid in the development of the KTuner “Stage 2” tune file. This also raises the boost pressure a little more over the “Stage 1”, as well as some small ignition adjustments that aid in smoothing out torque delivery after 5,000rpm.
Not wanting to press our luck with low end torque, boost is ramped in easy, picking up some gains everywhere.
The “Stage 2” tune shows a torque gain of 88ft-lbs at 3,200rpm over stock, with gains carrying the entire curve.
Next, let’s see how the Accord 2.0T stacks up against some other Honda engines…
2018 Accord 2.0T versus a stock 2017 Civic Type R.
As you can see, the Civic Type R is an animal compared to the people-mover Accord engine in stock form (as expected). Power carries much better up top as a result of the internal engine differences and turbocharger differences between the two engines. The Accord makes torque earlier, though.
KTuner “Stage 2” flash versus a stock 2017 Civic Type R.
The reflash makes the CTR play catch-up until about 5,200rpm, where the superior flow of the CTR results in an almost 50hp advantage at redline.
Here’s a comparison of the “Stage 2” Accord versus a stock 2017 Civic Si with custom KTuner tuning on 93oct. A great example of displacement at work.
Stage 2 Accord versus the same 2017 Civic Si with an ethanol fuel blend (35% ethanol) and of course, custom KTuner tuning.
And finally, a comparison of the 2018 Accord 2.0T with KTuner “Stage 2” flash versus a 2016 Accord V6 6MT with bolt ons (PCD’s, J-Pipe, exhaust, intake) with custom KTuner tuning. The turbo car make a boat-load of torque over the mighty J35 until about 5,000rpm, where the “big” V6 keeps carrying it’s torque flat, ultimately resulting in a power advantage way up top.
￼In conclusion, the 2.0T engine is very exciting, and the aftermarket is just getting started with this platform. As far as this engine’s ability to be a Civic Type R K20C stand-in on a budget, we don’t feel it’s on the same level, but only time will tell!
