K Series Parts cannot sell reflashes to customers outside of the United States per Hondata. The shipping address must be a US based address.
The K20A2 program advances the ignition, alters the cam timing and optimizes the fuel for a cold air intake headers and exhaust, adding 12-20 ft lb across the rev range.
This program was tuned specifically for a cold air intake, as they give the best power gains.
This reflash is not suitable with nitrous due to the aggressive ignition advance.

WOW, do this now!
Wow, this is by far the best thing I could have ever done to my rsx type s. I already had injen cai, hondata img, dc shorty header, test pipe, tanabe touring medallion exhaust. Which is great. But until I got the reflash, vtec dipped between gears making it incredibly annoying and weak. Now my vtec stays active between gears, my redline is 9k so I can actually stay in vtec forever even shifting at 8500. I was unsure about doing this at first, but I am so glad I did. I feel like the car was 0-60 in 7 seconds and after reflash 0-60 in 5.5 seconds. I unfortunately don't have a dyno to show before or after, I wish I did. But I can say DO THIS NOW! don't even hesitate, and if you plan on doing much more than bolt ons, get KPRO instead! I am very happy where I'm at now. I'm tuned at probably equivalent of street tune on a KPRO , just I cannot modify or change anything, which is fine with me.
Reviewer: Michael Bingnear on 8/27/2013
Not what i expected based on all the reviews
So i would say that if i had paid the $600 this reflash used to be i would have returned it screaming at hondata that it is garbage, I have a injen cold air and a test pipe and i honestly dont feel much of a difference at all besides the lowered vtec point, i picked up .2 at the track 14.8 down from 14.99 i feel that this reflash is a waste of money, save up and get kpro and then get it dyno tuned for max gains cuz the reflash is nothing big. disappointed.
Reviewer: Pablo Leon on 8/25/2013
this is a must if you own a type-s. sent my ecu out Wednesday afternoon got it back Friday really fast turn around
Reviewer: Justen on 9/27/2012
Well worth the money
After reading all the reviews I couldn't wait to get mine . Everything I expected. Im only running aem V2 SRI along with The reflash and i can feel the difference in power especially on top end. Very satisfied with this purchase. Thank you crsx for this great product!
Reviewer: Civlude97 on 8/17/2012
worth every penny twice over
sent the ecu out monday with standard shipping (10.6$ from MI to CA) and had to back at my front door thursday.. insane fast shipping and very smooth transaction. Once installed i noticed a HUGE increase in usable power and a very strong overall power band. at first its hard to get used to the elimination of the dramatic vtec dip. In all this was well worth the 300$ shipped i paid and is by far a must for those seeking quick, cheep power and dont plan on building or boosting any time soon. I have a youtube video of the before and after for those interested(youtube name Lilskater519).
Cars only other mods are AEM V2 and comptech shift kit.

02 RSX Type S Reflash
Noticeable change in VTEC engagement and low end torque. Love the 8600 redline:). Definitely more fun to drive but isn't worth the 600 it was a couple years ago. With a tune, I'm sure I would feel more of a difference.
Reviewer: Joe on 5/12/2012
Worth Every Penny!!
This Reflash really brings out the true performance of your basic bolt ons. Highly recommend this mod if you don't plan on turbo or supercharger. Couldn't be more happier!! Thanks to Club RSX and Hondata!
Reviewer: Stoopidstock on 5/9/2012
Love it man.
The product did as it said it would and as all of these other guys said. Best bang for the buck. Really unleashed some of that covered up power from stock. Love it, especially the 8600 rev limiter.
Reviewer: Joseph on 2/13/2012
Great bang for the buck!
This is one of the best mods I have purchased for my car. It entirely changed the powerband, allowing for a lot more torque in any rpm. I feel most of the power during daily driving, as well as up high in the VTEC range. It pulls harder than ever, and the 8600 rev limit is quite addictive! I highly recommend this modification for anybody who wants a great increase in power all throughout the powerband.
Reviewer: Spencer on 2/7/2012
I have an 02 Type S with 197k miles, CAI, and a longtube. The first vtec pull after putting my ecu back in left my hands shaking....the difference was unreal. Shipped it out thursday night, got it back monday morning: very impressed! Super smooth transaction!
Reviewer: A.G. on 8/10/2011
Definitely can feel some added power and car runs very smooth. The only reason I did not give it 5 stars is bc its almost too smooth. Gone is the aggressive vtec sound. The extra rpms is nice tho and has no problem reaching it.
Reviewer: Maryan on 4/7/2011
Good product, good gains
The reflash netted a good amount of power for me. See my dyno results thread where I compared the stock ecu with this reflashed one. Overall I got awesome midrange gains and 4-8whp all the way up to redline. Very happy with the results.
Reviewer: Trev on 3/24/2011
It's awesome, but already ready already to upgrade to K Pro. So that's the next purchase!
Reviewer: Josh bauerlein on 3/11/2011
This is everything I expected. This is how Honda should have released the type s from the factory. Great for those of you who have light mods and not looking to spend the money on kpro. I have a sri and exhaust and I could not be more satisfied for $290.
Reviewer: EnzoBeneno on 3/8/2011
Exactly what they promised!
For the money, there is no better mod. Quick and easy.
Reviewer: Ryan on 2/11/2011
Makes for a better overall drive
Best bang for the buck! It makes the car souch more fun to drive. If you're looking to get a little more out of your car without laying down too much money, this mods worth it. It's makes the car get up and go so much easier. Much smoother power band.
Reviewer: Vince M on 12/27/2010
Great mod for the price
At first, had the reflash paired w/ a gutted box, hi/dri flow filter and results were pretty good, especially in low/mid RPM as car pulled harder and was easier to drive in daily traffic. Recently swapped out gutted box w/ SRI; low/mid RPM feel the same still, but high end definitely feels smoother and pulls harder. I've read alot of reviews with adjectives like "wow" and "holy #$&!"; while I wouldn't go that far, I am happy w/ the reflash. After having it, I will say that I would NOT have purchased a reflash for 600 bucks though.
Reviewer: ricky on 12/19/2010
Thanks Clubrsx, thanks Hondata.
I'm extremely pleased with the new calibration on my ecm, it not only idles smoother and pulls with more torque at low rpms without hustle , but you can really feel the difference in high rpms, i got a 03 rsx type s with hondata img, cai,dcssrh,custom 2.5 catback and the newly reflash, i pulled on a s2000 with intake and exhaust( same car beat me for like a bus length before) im dont drive my car hard all the time, i love driving slow actually, but now when i do, it puts a big smile on my face.
i shipped my box(overnight) on wednesday the 15th at 5:00pm and got it back friday the 17th at noon!, thanks club rsx and thanks hondata for a pleasant transaction.
Reviewer: jon-js on 10/13/2010
thank you clubrsx for smooth transaction. The reflash is very good.I like the added torque on the car. very smooth going all the way up on the RPM.
Reviewer: scott on 9/14/2010
hondata fast shipping
Holy Shit!!!!!!!! thats all i gotta say!!!! crsx FTW!!!!!!!!!!!!!!!
Reviewer: Jackson on 9/6/2010
Best bang for bolt-ons
I have an ep3 with a k20a2 swap and the usual bolt-ons I/H/E. Before the reflash the car felt very rough right before the VTEC crossover and I had to downshift to climb a hill or pass cars on the freeway. After the reflash I have a lower VTEC point and more rpm's to rev to the new 8600 redline. The car feels quiet even when crossing VTEC and driving it is no longer a fight due to the more usable torque curve. The car idles smoother and driving it feels like it should have been this way from the factory. I would simplify it by saying it brings all bolt-ons together
Reviewer: Abel Correa on 8/23/2010
Great buy and great shipping!
The reflash works great! Power gains are noticeable depending on other add-ons of course. Vtec engagement change is very helpful.
The most important part is the shipping service. It arrived right on time very well wrapped and once installed everything turned over perfectly.
Great buy if you are on a budget! No more having to rev it too high just to stay in vtec.
Reviewer: Juan Santiago on 8/18/2010
More power for the money than any other upgrade.
My RSX feels like a completely different animal. I live in the city, so the torque gains are a HUGE benefit. I no longer have to hit vtec to get around city streets in a hurry. AS long as you're keeping your RSX N/A, you'll definitely want this upgrade. On a side note, my check engine light came on as soon as I started the car, after receiving the ECU from HONDATA. I can't say for sure that it's related to the reflash, but what are the odds? I'll have the codes checked out to see what the problem is. Either way, it's still worth every penny and more.
Reviewer: mike on 8/11/2010
awesome definitely made a difference!
I was skeptical about the reflash but its awesome. I can probably actually get to at least 150mph now. sixth gear actually does something now. I have pwjdm intake, obx race header, rbc manifold, and rs×r exmag exhaust and with the reflash the car pulls hard as hell now. Its a good first step towards getting kpro one day. You can always upgrade at a reduced price. Would definitely recommend reflash!
Reviewer: Stacy on 7/7/2010
made my car run better. overall a good buy, especially for the vtec kicking in at 5200rpm and the rev limiter at 8600rpm.
Reviewer: jason on 2/24/2009
best bang for the buck
imo, reflash is the best performance mod you can make when you're starting out. upgrading to kpro is a great idea after you add on all the bolt ons. worth every penny.
Reviewer: Bobby Ferreira on 9/27/2008
Totally transformed the car, felt brand new after the reflash. I have a SRI, Exhaust, Shorty Header with Hi Flo Cat and the car was reaching 70,000 miles when I reflashed it. Best bang for your buck, no problems at all.
Reviewer: brett on 9/27/2008
I was amazed... i didnt notice the vtec kick in in 3rd and all of a sudden i was going like 80. makes the car much smoother and the added torque is really noticeable when just driving around parking lots and such... only complaint is no stickers...:(
Reviewer: jb on 3/26/2008
Great for lightly modified applications.
This ECU software really opens up the engine to make better power for lightly modified applications. For the price, it will give you more power than any simple bolt on, and when paired with aftermarket intake and exhaust the results will be slightly better. Gains are seen on both the low end and the high end with the improved VTEC window, and the car seems to have no problem handling the increased redline (though hitting the higher rev limiter is not a good idea). The discounted upgrade to K-pro is good for those who plan to upgrade to a more heavily modified setup later on.
