Remote jail break ECU?

[pkwon131]

Hey guys, didn't know if this was in the right thread or not.

So i saw a facebook post about remote jailbreak on the fl5. They were advertising that Serge Bo (upon some research, big tuner for honda's) can remotely jailbreak the ECU. Just wanted to see if it was legit. Would make my life much easier not having to ship out the ECU and be down for a few days.

Thanks!

He’s on Reddit answering questions. Seems legit. Not bad for 250$

Of course I just jailbroke mine and paid a good bit for next day shipping

Probably me. I’m still on the fence. I kinda don’t have as much faith in the k20c1 as I had in the ea888 gen 3 tbh. I can’t help but think maybe I should at least swap rods…..

I've only ever seen the name mentioned on some Facebook posts, I've never seen his name mentioned any where on any forums. Since I've only seen it on Facebook, I would take it with a grain of salt, but if someone does it and it works out, that just means its another place to get your ecu jailbroken.

If true, it sounds like the OTA key may have been compromised...More reason to consider disconnecting your car from the mothership.

Why is that ? (agree the 888 is great)

Ea888 can take 450wtq all day and night and straight up survive. No need to tune in fake lag. All that tq can rush in immediately too. Has a semi closed deck too. Early days, I remember avoiding a tune on my fk8. Cats were just bending rods with bolt ons and a tune till tuners learned delaying tq a hair helps. Just makes me nervous

not saying the k20c1 is a bad motor or anything. It just doesn’t fill me with confidence.

Meanwhile my old GTI was a 410whp tank

They aren't tuning in "fake lag". The stock turbos on these cars are relatively small, so they hit peak torque around 3,000 rpm (this is mechanical, d/t turbine / compressor size). > 400 wtq below 4k rpm on these engines is risky (d/t load on the rods), so responsible tuners don't request more than that from the stock turbo.

A larger turbo won't make peak torque until higher in the rpm band, so those running larger turbos can make higher torque requests than you would on the stock turbo.

There is a lot of evidence that a responsible tune on a stock turbo is fine, and there are well reputed tuners for this platform that are familiar with those limits. Just don't ask more from the stock turbo than you should. If you want more, you'll need to upgrade the rods or the turbo, and generally people go the turbo route first, as the stock turbo is small enough that many don't feel it's worth running it on a built motor.

Depending on what you want to run for the turbo and for fuel, you can surpass 500 whp on this platform on a stock bottom end. (Wtq will be lower.)

Ok

but other motors can do it. Specifically one with a semi closed deck and forged rods from the factory

I didn't say otherwise, lmao, and I am not trying to promote one motor over another. I am just giving you feedback on this one.

Sorry man. I’m just salty that the fabled k20 can’t hold a candle to a Tiguan engine in regards to internals

I didn’t mean to be a bitch. I’m just salty. I’ll do better

also. Not being a dick or sarcastic

he is 100% legit and a good dude I did my research he also has certs straight from Hondata. he is in my facebook group and can answer any questions you have if you post. He decided to expand into the CTR world people int he TSX world swear by him https://www.facebook.com/share/g/1G8X2mLKfY/

No worries I do understand where you're coming from... A lot of design choices with this platform rub me the wrong way. (For example... why don't we get a baffled oil pan? Why don't we have multiport injection? Why does this motor route exhaust out the front?)

Sadly, it's not the fabled K20 You could argue it's more similar to an EA888 than to an older K series.

Older K series are valued for their high flow cylinder head. K20C1 doesn't have a high flow head. It ditches vtec on the intake cam (relying on the turbo instead), and this limits how aggressive a cam you can run, as the intake cam is always running the "aggressive" lobe. It also uses tumble ports (which cut down on flow) to help with fuel atomization via direct injection (technically this is an improvement, but it does mean you won't get the top end power older K engines were famous for), and -- like the EA888 -- it uses an integrated exhaust manifold, which limits flow.

My anecdotal experience is that, in stock form (meaning stock tune), I prefer the K20C1 to the EA888 (experienced in Tiguan, GTI). The K20C1 seems to be more rev happy, and I prefer the power curve. I am not sure how the intricacies of the head designs compare, so I won't make any claims re: potential. It does also seem that EA888s have more issues with carbon buildup and valve stem / turbo seals. That's all anecdotal (and I haven't experienced a tuned EA888).

Having said that, if you are tuning, I am with you that the forged rods are an advantage for the EA888. I think, depending on what your goals are, etc., the EA888 can make more sense for chasing power / torque in a low investment build. If you are running a bigger turbo, though, those torque concerns aren't as relevant (because of the resulting torque curves), and I would think that, once you go beyond that (and start building out the bottom end, porting the head, installing big cams, etc.), there probably aren't many distinct advantages between one motor or the other.

I will say, as someone who has been frustrated with how Honda abandoned many of the "advantages" of the older K engines, some of these design elements probably aren't worth sweating over. The reality is, execution / implementation matters more than specific design choices (for lack of a better term). A good example of this would be how well implemented FWD is on this platform. In a vacuum FWD sounds terrible. Here? It's actually pretty good. You can make pretty decent power on these motors with minimal investment, even if they don't check the "forged rods", "high flow head", "aggressive cam" boxes. Admittedly, I struggle to understand the value of high HP FWD builds, but you can flirt with 400 whp with a tune, and 500+ if you add fuel / turbo.

If you are "losing sleep" over this, check out some dyno graphs of a tuned stock turbo vs. a Kuro+ or (better yet) an RV6 R660. You'll see that the torque curves are completely different, and this might put your mind at ease re: future potential without having to build out the motor.
