Has Anyone Tried the Hondata Reflash ?

I know the FlashPro is going to be the way to go for most owners looking for a tuning upgrade. But I like what I'm seeing from the Hondata Reflash, all of the performance benefits with part throttle settings left same as OEM. Best of both worlds. Price is right too, maybe half the price of the Flash Pro, and from what I've seen this is available now. I think I'd rather go with the guys at Hondata and their expertise as they've had lots of time to tune and analyze the data. Sounds like a reliable setup to me.


Curious to know if anyone has one of these upgrades yet ?

I seriously considered doing the reflash and still am.We will see at half the price it's just so tempting.
It certainly is tempting me, and I probably won't do any other mods in the future, if anything maybe just an intake and the reflash should work fine with an intake. The Flashpro would be nice to go with additional modifications as you can change the tune if needed, but the reflash should serve me fine.
What exactly does this do and does it cause warranty issues?

they revise the boost and ignition timing tables mainly at WOT settings. According to Hondata it spools the turbo 500 rpms earlier, boost is increased 3-6 psi, ignition timing is advanced. Gains reported to be 20 whp across a decent area of the power curve, it will require use of higher octane fuel.


If Honda found out about this and any similar mod it would definitely void the powertrain warranty, something to definitely keep in mind. Then again I wouldn't ask Honda to fix something that I broke.
That's one advantage to the Flash Pro end user version as the ECU can be returned to stock easily.The custom tune is a lengthy process though sometimes with up to 30 revisions.Ive done 5 revisions sometimes in one day.Kinda sketchy too on WOT pulls up to redline as there is a Iowa State Patrol facility just off I-35 near where I do them.Im a bit curious how easy it is to pull the ECU.I would guess also that you'd have to reset some of the electronic gadgets after reinstall.

Honda has put this ecu in the engine bay, it is now a 2 minute process, much easier than having them mounted under the driver side dashboard like past Hondas. Simply pull the battery negative cable, lift up the ecu connectors and it is done. You might lose your radio presets, and maybe some of your control settings, not a big deal though.
I tried looking into the reflash and hondata only has one for the older model year Civic Si. Am i missing something?
Im personally going to wait for the Hondata FlashPro. To me, its worth the extra money to be able to have multiple tunes and revisions as well as be able to return the car to stock for any dealer service without having to send the ECU in every time. Sure, you can buy an extra ECU but with that additional cost, you might as well buy a FlashPro

I believe you have to purchase it through one of their dealers, and then send the ECU to Hondata , and they will send it back to you. If you locate the dealer in your region they will have it listed on their website. I found a few that had it.

Agreed. The ability to remove a tune when needed so the warranty won't be voided is worth the extra cost unless you don't really care for warranty.
Hopefully this month we'll have Flash Pro.As soon as I know y'all will know.

Anyone smart will make sure they can go back to an OEM tune since we are working with a new engine here, not something that has been around long enough to have a say in it or have enough confidence in them... although overall Honda is trusted. I just like having a bit more confirmation and confidence before doing things like this.
If they really wanted to find out if you tuned the engine or not, it's really not that hard for them. Even if you change the ecu, there's serial numbers and data logs that'll show it's been changed. You pretty much go into this hoping that nothing happens to the point where you need it warrantied because at that point, they can deny your claim if it's relevant to the issue caused.
