ITS Hondata Jailbreak

[NoelPR]

I'm more than happy with a custom tune without any other mods. I can live with that.

Prl is actually making around 500whp without fuel upgrades. People are finally learning how these ecu's operate logically. And the tuning has gotten better by a factor of 10. Now that the platform has been out for like 7-8 years support is finally catching up to a degree that tuning has become safer and we now know the actual limits on the internals and fuel system.

I will mention that it's always best to upgrade your fuel system because the truth is that it's always safer. However tuning in general is safer at this point then what it was originally.

But they are to a point were they beginning really push these motors safely. Which is awesome. But at the end of the day your tune is only as good as your tuner. So make sure you find someone with real world experience specifically with these platforms. These ecus are torque tuned meaning the ecu will continue to hit a specific torque target not necessarily a fuel target or rpm target. It's mainly torque based. It's a different tuning method from traditional methods.

Maybe someone else can expound on these points further with a little bit better insight to how it's done.

Where have you seen this? I have seen stock cars fuel limited, can't see making over 400whp reliably without a HPFP upgrade at the least. If you start running Ethanol it gets even worse. I think you can hit 500whp without injectors, but it will be tight.

I do wonder if the FL5/DE5 still need the HP fuel line mod also, haven't seen it confirmed.

They remove some of the sticker info?
Sorry, I've never sent off for a tune yet - this will be my first. My LS tunes were done locally, so this will be quite different for me.

No.lol I blurred it. Don't want certain someone to find out

Don't forget to peel that Hondata sticker off too, just in case

IIRC I remember reading on a forum thread I believe on CivicX. Things have changed in the last 2 years. Tuning has improved immensely. I believe it was there shop car they were referring to and I believe it was the FL5. The FL5/DE5 platforms are better than the FK8. They have more fueling capacity out the box compared to the FK8's. They're able to run tunes more lean safely.

Fuel system seems to have the same limitation as the FK8.
FK8 also had overheating issues which was improved in the FL5/DE5.

Pardon my naivety and granted this is coming from the manager of my dealership, but he recently sold his FK8 that he brought to the same local track that I will be bringing this car to and has a coach there just like I have set up - but he explained that if there ever is a suspected issue, the dealership will send the ECU directly to Bosch and that they will 100% find the tune every time and he has a friend that has just dealt with the same issue recently to no avail.

Is this true?

Yes, that should be everyone's assumption when dealing with high value repairs. Honda will get someone from Bosch to look at the ECU and Bosch will know if it was modified. You can get into an argument on if your tune caused the damages, etc, but it will be an uphill battle, especially if you started the warranty claim under false pretenses (flashing back to stock and not admitting to the tune).

Where it gets grey is what is a high value repair. You might be able to get away with a blown turbo for example, depends on how corporate feels that day. Is it worth paying Bosch to look at it or better to just fix it?

The good news is (at least to my knowledge) as long as you return your tune to stock before servicing, Honda can't tell you have a jailbreak, they will just see the stock tune. Same with any emissions testing. So as long as your car stays in Honda's hands, you should be ok. If someone does know of Honda flagging cars like Audi does, I would be interested to hear.

For my build, I am trying to limit how much I would need to reset to stock if I had to return to a stock tune. That's why I like the MHI Stage 2 turbo, it looks stock and can run on stock tune if needed. Sadly, the HPFP can NOT, so that would need to be swapped back to stock before dealer or emissions inspection.

You cannot hide ECU Reflashes. Everything has a digital footprint these days. Even some piggyback's you can't hide. Depends on how well made it is and how it communicates with the ecu and interprets the signals sent.

But they cannot void a warranty even on a Reflash/Tune unless they can prove that it caused the failure. If you own the car and have the right to modify it.

Most Techs though are pretty cool about stuff like this as long it was done correctly and safely. But a dealership can always reserve the right to refuse service though.

So you do this at your own risk.

I run a shop and I don't void warranties or refuse service unless it was the cause of the failure.

Anytime you increase the power on a car it reduces the life of that car because it puts added stress on the parts of the car. Regardless of how well a car is tuned and ect. More power, more torque, more wear on all of your components.

Thanks for the info! I had planned on voiding warranty after a little time had passed, but this makes me feel like I should just go for it. I was also looking at the RV6 turbo, but hadn't researched a ton of others. The one you are talking about has certainly peaked my interest!

Thanks for the advice. My dealership is similar to yours, they will always service and has mentioned to me that as long as I don't start messing with the engine internals, it shouldn't be a problem. But if they find the ECU was flashed, they likely won't cover anything. So I sort of thought that the cost of extended warranties is roughly half the price of a replacement engine, so what's another couple grand to have fun while we can?

You could always go the piggyback route. Keep it conservative and your less likely to void your warranty. People have differing opinions on them. But they can be removed without making permanent changes to the car. And if you buy a high quality one that has a literal proven track record with proven results. You could easily add 40-80hp depending how aggressive you get with it. Plus there's the ethical dilemma being dishonest/deceitful with the dealer/manufacturer.

But if you buy the right one and you use it correctly you could safely make some extra power and make the car more fun. If you want to message me directly and are interested I could make a recommendation for you.
