Can finally say there is support for the 2015 ilx. Was able to get a tester unit and have Ktuner develop a base map.
Luckily there is a local tuner ( @javituned on instagram ) who is about 15min from where I live. Was able to set up some dyno time and get her tuned! Cannot say how great it has been working with Ktuner and Javituned to get this all done. would highly recommend to anyone in the so. florida area and to anyone with an ILX trying to get some more power.
On the base map / 3in downpipe / stock intake the car made 194 hp / 174 torque
after installing the PRL short ram intake some updates on the tune and about 15 dyno pulls car finished at 204 hp / 175 tq. with gains all across the rpm range. VTEC kicks in at about the same time as stock with the redline moved to 7500 rpm. Really happy with how the car is running and pretty excited to move ahead with doing some more engine work.
Really is an eye opener realizing what it takes just to produce the numbers Acura claims to the wheels.
Makes me lol at people "I got an exhaust intake and header. I figure Im around 215hp now." When the car originally advertised 205 in the brochure. No sir. It takes a full blown tune to reach the brochure numbers at the wheels.
Ktuner will definitely be my path in the future as hondata said flat out they wont produce for the R20 while Ktuner was ready to send me a test unit. Ktuner FTW. Hondata is just in it for the moneyz. They dont support the community.
With out a tune on this car at least there isn't much power to be gained even with i/h/e. The downpipe has been proven to gain around 10 whp with out a tune, most likely because it gets rid of the cats bolted right on to the head. And even then on a different dyno it could make more or less power, feel like this dyno is slightly generous but definitely not anything out of the ordinary. the way I see it, I can compare to other people who have been on that dyno, pointless to compare to others numbers otherwise.
If you have the opportunity to get a tester unit through Ktuner I would definitely pull the trigger. Its not something that will happen over night, i exchanged over 40 emails in the span of maybe a month or so while Ktuner developed the support to add in but the end product was worth it especially since its really the best option for the money.
Not too sure if anyone has tried the RBC intake manifold on the 2.4 ILX, its a pretty popular swap for a lot of the 9th gen civics and personally I've enjoyed it.
Over the weekend was able to get a comparison done from stock intake manifold/ PRL short ram intake/ Full Race down pipe / Tune - TO - RBC intake manifold (ported to match throttle body) / ZDX throttle body, PRL SRI for RBC/ZDX, stock RSX injectors (same 310cc just fits RBC manifold) , Same down pipe and retuned.
Just Swapping the manifold on the same tune as the stock IM we went from 204 to 210 whp , after a few changes to the tune we were able to reach 216 whp / 173 tq. with some loss of torque the lower RPM but makes for a fun drive past 5k RPM.
Will eventually go will bigger injectors and run e85 hopefully reaching the 225 to 230 whp mark.

Thanks for the work you put in getting support for our 2015 ILX's. I also have a white 2015 ilx 2.4 and have been hoping to add a supercharger at some point in the not-to-distant future.
Is forced induction now an option for us through KTuner? I had plans to buy a 2013/14 ecm, the A03/A04 model that Hondata supports, but hopefully now I can use that $600 elsewhere.
Not sure if the ecm swap would have been as simple as I envisioned.....probably not, but it was my only hope.

Last i spoke to ktuner there was only bolt on support. Nothing for larger injectors or fi. Hopefully that has changed!
I am posting this for anyone out there who owns a 2015 ILX 2.4 and wants to add forced induction:
I purchased a new 2014 ILX 2.4 ECU (37820-R9B-A03) from an online Acura parts store, the cost was about $700 after shipping.
My local Acura dealer (Cerritos Acura) removed the original ECU (37820-R9B-A21), replaced it with the A03 ECU, and programmed it to the car. Cost was $160 for one hour of labor.
The A03 ECU is a direct swap for the A21, and the A03 is Hondata compatible.
I spent countless hours comparing 2015/2014 ILX part numbers and the only difference I could find are the ECU numbers.
So if you found yourself in the same situation as I was, and are willing to spend the extra $700+$160, you can add that supercharger or turbo kit using Hondata.
Just in case anyone is curious- no warning lights, nothing different at all in the way the car runs.
Since its the only thread I can find on this anywhere and the ecu swap is still needed for Hondata usage on 2015's. Can any of you give any tips on how they programmed the 2014 ecu? Does your car appear as a 2014 in Hondata or when scanned using a OBDII scan tool? Can you swap back ECUs for emissions etc. If so? I live in a small city where the tech's may not be real familiar with reprogramming ecu's. They definitely didn't instill confidence when I talked to them on the phone.

This is good to know, have been off the forums for a few years - still own the car.
Major changes since my last post:
K24a2 head swap (Still On Z7 block) with 06/08 TSX exhaust cam / Z1 intake cam.
RBC manifold, RDX Injectors, On e85.
3in Exhaust to a Ktuned Downturn muffler.
R888r tires.
JaviTuned
Best dyno #s were 238 HP / 192 TQ
Will put up pics of the swap being done at some point. have moved over to IG for most updates on my car.
Has taken a long time to get to this point and my tuner has told me recently that he was able to figure out how to tune the ECU to run forced induction. On the turbo set up he figured out they were limited to 9/10 psi.
While this is great and will make some fun power in a daily driver, I know switching over to the '14 ECU and using Hondata will really open up some options for getting into higher boost levels.
Car has been on e85 for years, has around 75k miles at this point (i think at leas 40k have been with a tune and mods)
Also revving to 8100 with my vtec at 4900/5k so not going easy on it either.
Engine still runs well, could use a refresh on the a2 head but will switch over to either a cnc ported head or a z3 head at some point.
I have a few buddys with 9th gens si that have gone through a few transmissions over less than a year. clutch isn't slipping but the shift cables are stretched and in can give me a hard time going into 2nd when im really pushing it - wouldn't surprise me if the trans will need a refresh at some point soon as well, but has lasted much much longer than what is typical for the level of abuse the car sees.
I'd save a search on ebay if there isn't one up there... it's not like there are a lot of people looking for used 2014 ECUs and probably plenty being wrecked. I got mine for like $50 shipped LOL Of course add $150 for a dealer to program it, and the Hondata flashpro on top.
Considering how much I spin my wheels as is with summer tires a Takeda intake, ported stock intake, and full race downpipe I'd think the A2 head route and extra rpms would be a fun upgrade for the fraction of the cost of boost. Of course living in CA if I have to revert would be a hell of a lot more work!!!
