Post v6 ECU tuning/reflashing thread

So I searched and from what i already know it seems like any serious gearheads go for a standalone to tune with(which is what you should), however for the normal guys who just have bolt ons etc, there is still a need for tuning.

Anyways i was curious if anyone here can give me input on the people who have tried to hack the ecu or what hondata has said in the past.

Reason i ask is because I may feel the need to pursue this and will spend the $$ on dynoing etc.

thanks in advance for any input.

I think Hondata flat out said no, but I could be wrong.

Not too long ago I looked into a similar process, and found the next best thing was a PNP harness from Boomslang, and they will make it to order for about $250. So you can tune via a e-manage, FI/C, or even a AEM EMS.

Apex'i AFC Neo, Boomslang Harness and tuning cost roughly $750-800 total, gained 10 WHP peak and really smoothed out my power curve, I have every bolt on available for the 7th gen at this moment, so that was the way I went, worth every cent I spent.

I thought that the ecu will de-tune the neo after some time?

True, the ecu will detune the neo and others in time. The only one I hear it wont detune is the aem FIC. If you want to get the neo or others then get the actron cp9180 and that will allow you to reset your ecu as well as monitor your whole car. I feel its much easier and better than taking off the negative on the battery for a half hour or so and plus I get to see how my car is runing. Also you can help friends out if they need. lol. I was able to notice on my gf car which is a 2003 cavalier that it is running really rich so I will keep an eye on it with the tool. Also saves you a $80 diagnostic fee that the dealers will charge. Check out amazon.com or your local auto parts store for it. I have a neo and I am so far happy with it. Will be getting my car re-tuned once my j33 breaks in.

Hondata did a reflash for Ussi and his 3.5 TL S/C.

^^ They did. What I don't get, is how they say there isn't enough of a demand to make a "J-Pro," yet they made a reflash for ONE person Is that a joke?

All trims of CL, TL, Accord V6, RL, Odyssey, and MDX use J series motors. I think there is more than enough of an aftermarket for one, but that's just me.

I actually just sent them an email. Hopefully, along with all the others, they can reconsider.

To whom it may concern,
I realize that there have been many failed efforts to propose to you an ECU reflash for the Honda J-series engine, referred to as "J-Pro." I'm under the impression that since so many attempts have been made, that there is a significant demand for it. All trims of CL, TL, RL, Accord V6, MDX, and even Odyssey use variations of the J-series. There is no hope for those with the J-series on tuning because every other tuning agent seems to detune itself after a period of time. PLEASE reconsider J-Pro for us!

Sincerely,

Bryan

^ hell even civics are swapping J's in, so there has to be some kind of support and as far as ECU for Honda's, Hondata has done a great job.

^^ Exactly. There is none better than Hondata for Honda, hence Honda in the name. If they were to add J-pro, the hope for the aftermarket of J-series owners would soar to new heights!

Sh!t, I even wanna throw a J in a Civic

glad to see some response on this subject. I don't believe in investing into an AEM unless your boosted. plain and simple. If you had a hondata reflashed for each j-series, then at least someone with a 3.2 with 3.5 cams could try a reflash FOR a 3.5 and see if it runs better........

I hear you...when I had my RSX-S I got a Hondata reflash and it was unbelievable the gains I saw with just an intake, exhaust and the reflash. Not only were peak gains amazing, but I was getting 95% of torque at 3k rpms, which is freakin' awesome for a K20A2 which relatively speaking doesn't make any torque compared to the J series. Imagine if a $600 reflash gave us 15whp/15wtq, smoothed out the power band, gave us more available torque down low and lowered our vtec point to smooth the transition (if Hondata through testing saw that a lower vtec engagement would be beneficial of course). When I saw "smooth the transition" I am referring to the fact that on the K20A2, there was a major torque dip at 5800 rpms (where vtec engaged). I'm salivating just thinking about it.

We should create a list of interested people. I'm not sure if this has been done before, but if it hasn't... let's make another thread for it. Maybe they'll be interested if they see enough committed people?

I think quantity is going to be the issue. They did it for the RSX-S because the demand was extremely high - I wouldn't doubt if they sold over 1,000 reflashes in the first year. I don't think we can muster enough of a crowd to cover their R&D that would be necessary to make the best possible Hondata program for our cars.

For the RSX-S for example, they had a number of reflashes that took a lot of testing, research and dyno time:

1. Hondata tune for CAI/exhaust/header (though you could run lean with a race header with this setup)
2. Hondata tune for a Type R setup (Type R cams, intake manifold, race header, etc...)
3. Hondata K-Pro - fully customizable for any setup.

There might have even been more, and for the basic Hondata setup it was $600. For the K-Pro it was $1,000 IIRC. But like I said, they literally had thousands of people lined up to buy this product so they basically knew that all their R&D, research, dyno tuning, etc....plus profit would be covered fairly quickly. Unfortunately, I don't think we can muster those numbers. We'd be lucky if we could get 100 people IMO and I doubt Hondata would do a reflash for 100 customers. I could be wrong, hell, I hope I am. If someone wants to hit them up and see what numbers they would need to see to get started, give it a go!

^^ True the RSX has a much bigger market, but it's only one car. Remember..it's not just 7th gen Accords that have the J series. Acura TL, CL, RL, 6th, 7th, and 8th gen Accords, Odyssey, MDX, Ridgeline, and doesn't the Pilot come with the J series now? I think there would be plenty of aftermarket support for a "J-Pro."

I'm sure there are at least 100 on this site alone that would be interested. Also because there is no J-Pro available, some people may not even think about Hondata because it's not a choice. Meaning, that some people who need a tune and are using Apexi NEO, etc., may think about switching to Hondata. I hope this works!

Good point...heck, I hope it works too. Like I said, when I had the reflash on my RSX-S it was night-and-day difference. Plus, it's completely sleeper...no one knows (obviously) that you are running a new ECU program. It gave me so much more torque down low, changed the vtec crossover so it got rid of the dreaded torque dip at engagement, and gave me 15+whp/15+wtq peak power with just a CAI. Amazing investment...worth every penny. Plus it was nice reving to 8600rpms

I have the apexi neo and I would change to Hondata in a heartbeat. I always wanted hondata for my car cause every car they do has great results and they could do wonders for our cars.

+1 for Hondata, so that would be at least 6 peps right now for it, now a couple things to keep in mind on this, there are basically 4 different sensor setups just to cover 98-07 and a huge differentce between 3rd gen TL/7th gen AV6 and 6th gen AV6/2nd gen cl/tl, then of course there is the 03 CL-S mt which is a sensor setup all to it's own, so it is not like 1 version would fit all our cars . Would I love to see Hondata for our cars yes, but like others do I see them doing it, probably not.

Oh, and one other little piece of info, K,H,F ecus came out of Japan made by Denso (a company you can get info from with enough pull), all J ECUs that I have seen thru the 7th gen AV6/3rd gen TL are made by Motorola, good luck getting anything out of those bastids.

COUNT ME IN!!.. I propose There should be a custom Hondata reflash for CAI, Richies J-pipe, and Richie's 3 cat deletes. Id pay 400-600 for that.

Put me on the list.

reflash kind of sounds like a jip if you later add more performance upgrades bc you can't retune the ECU at all unless hondata makes you a custom flash.. with all of the different combinations of performance upgrades out there... one general reflash will never fully satisfy everyones configurations. better to have a standalone or piggyback that can be modified and evolve as your car's configuration evolves
