Use a few cars of street demo car and super endurance racing car, it is a confidence that was repeated by setting basic data produced and super endurance race and street real running by DYNAPACK. Power up & torque up at all rpm range, you can be assured a high response.

Fuel economy improvement of at power-up and street running of sports driving and I was both. It is immediately experience possible sport ECU! Across the entire region, fuel MAP, knock Sensi Stability MAP (ignition), variable valve timing MAP, retard MAP, we have revised the entire area by the release of the torque limiter.

Pull out the original and thereby have power & torque of auxiliary equipment such as engine body and breathing.

Because it is a reflash tune to change the only program of internal ECU, also corresponds to the immobilizer, can be rewritten work in a short period of time.

Sport muffler, catalytic-less, big throttle, Tsuchinoko chamber mounted, lightweight flywheel exchange compression ratio up from light tuning, such as, high cam shaft replacement, exhaust amount up, and also widely in high tuning vehicles such as 4 throttle mounted (power Sulo exclusion) correspondence ...

Please tell us when you order also to the specification of the following requests.

(Can be changed at customer's request item free ※ 4)

○ REV rotational speed limit ... change freely

○ LAUNCH rotational speed limit ... change freely (used for pit limiter ※ separately wiring required))

Can be changed by changing possibility ○ misfire counter SW иии cancellation to-wire slot in lightweight flywheel at ○ electric throttle SW иии Cancel

○ immobilizer ... Cancellation



[Basic Specifications] L15B 1,500cc compression STD cam shaft STD)

● REV rotational speed limit rotation speed --------------- 7200rpm (※ 1)

● VTC rotation speed --------------- Tuned optimization

● fuel MAP ----------------- Tuned optimization

● knock Sensi Stability MAP (ignition) ----- Tuned optimization

● electronic control throttle MAP ----- Tuned optimization

● electric fan operating temperature change ------ 80 ℃ (※ 2)

● immobilizer ---------------- corresponding

● Speed ​​limiter ----------- release

● LAUNCH rotational speed limit -------- 4400rpm (※ 3)

(※ 1) REV rotation speed but can be freely set, please specify the specification of the engine top of understanding.

(※ 2) Recommended electric fan operating temperature fan on-80 ℃ (genuine 93 ℃) / fan off-75 ℃ (genuine 90 ℃) Also, fan operating temperature is I can be arbitrarily set. In those who use in cold climates, etc., please feel free to contact us if you have any special hope.

(※ 3) revving REV rotation speed (LAUNCH rotational speed) is can be freely set. Please use in such as 60km / h limit in the pit lane. You will need a separate installation of wiring and switch.

(※ 4) With regard to post-specification changes, I will be charged separately \ 50,000 (tax not included).



Also I heard the current car alignment Settings by DYNAPACK and real running. Please feel free to contact us.

So what do you guys think?

it probably is only for JDM ECU

Unfortunately the past two generations of fits in the US of A got shafted with this ecu since the JDM version isn't interchangeable.

However I is nice to see a company is finally starting to take advantage of tuning the direct injection.

Thanks Kyler! On the positive side, it seems there have been a few things on the JDM Fits and USDM Fits that are plug-n-play. If the plugs are the same, the engine and the ECU relatively the same, perhaps simply unplugging the stock ECU and plugging in a reflashed JDM ecu is an option. I'm game! I responded to your PM. Let me know either way, I'm game to test. Thanks Kyler!

That idea sounds simple enough but I know with the gd3 there were some problems when someone tried to use a jazz ecu back in the day. IIRC the ecu needs to have the matching gauge cluster and key for it disable the immobilizer. I am just waiting on a phone call for some answers.

I don't quite see what the gauge cluster's role in this situation other than telling what the engine is actually doing but there iS a way to bypass the immoblizer and get the car to start while using its factory PCM.

I just remember Chatting with Jpax and hasport's Brian about needing the gauge cluster when using the stock ecu. This is back when they just did the first k swap fit (jpax) so perhaps there is a way around that now that I'm unaware of.

I see, I didn't have any knowledge of this at all.

Updated with J's Racing Dyno results!

I'm already trying to get my hands on this unit. Need one for the USDM CVT NOW. Come on J's....work with us. :-)
I've already emailed them days ago. J's Racing USA is working with J's Japan to see what they can do for us. You manual guys maybe the first lucky ones to test. We can hope right?

In other words, I'm cool with sending them an ECU to reflash. Don't see why they couldn't with a little work. Either through J's Racing USA or someone else.

Update!

After trying to contact J's Racing Japan through several different methods, here was their response to a question I asked them on their Facebook page.

Hi Kevin,

Thanks for contact.
unfortunately we have only JDM 6MT ECU.
USDM CVT GK5 ECU is completely different from JDM one.

Now we don't have any plan to make USDM one.

Please understand the situation.

Thank you very much.

It's not the end of the world but that was their response to me. And no, I don't 'understand the situation'. Haha! It is what it is though.

Perhaps someone would pay for a reflash to get better fuel economy. They even mention better economy with the reflash on their website.

The time it'd take to recoup those costs pretty well eliminate all but the least financially responsible fuel savers.

I'm starting to think you are right Mike. Not just about an ECU reflash but any modification in general. I've been looking on other Fit sites as well and am seeing the same things.

I'm going to start trying to be active in foreign Honda Fit/Jazz forums as far as modifications go and get what I can from there. The market for modifications may be much livelier in Japan, China, etc.

They do VOLK or RAYS wheels, Endless BBkits, race seats, gauges, suspension, Next Miracle X bars, shifters, carbon fibre hoods and fenders, final gear fixes, turbos- hell even full K20 swaps withought even thinking about it!
In Thailand, Indonesia and Singapore, if you buy a Jazz, you gotta tune- it's that simple!
