Somebody once said something about driving your car for a little while after flashing the tune back to factory, maybe a good 24 hours beforehand. I forget why or what that changed.

I was told though that they can't see ECU flashing history. Obviously I was mistaken.

Would a smog check place be able to see this kind of stuff, and is it a problem if so?
According to the reddit post, the person drove 150 miles after flashing. In California smog is about every 5 or 6 years, I think here we would need to worry more about modifying the stock intake/CAT, which is illegal in this state

Surely the DTC is reset after a FLASH, I had already written it in some posts

it is my right to see where it is written that I have modified the PCM
you need a written report
The guarantee on words is not invalidated
it could also just be a blef attempt to see how the customer reacts

A client who did the reflesh will hardly fight
DTCs can and do get reset. But it does not seem to apply to burn-in codes or pending codes. For what it's worth, this issue doesn't seem to come up during a routine OBDII scan. Only when Honda attempts to access live data/history surrounding a very specific event (like an over-rev).

I hope it's actually eight years, heh.

I plan on adding a PRL intercooler and CAI, and then removing it come smog check time.

So I wanted to bring this back up because this is starting to make the rounds again. We are seeing some examples of owners coming back reporting that Honda can pick up vehicle PCM history, regardless of whether the ECU is returned to factory state. It should be emphasized that in all cases, Honda ended up doing an in-depth diagnosis to read live data. And I'm not sure exactly what gets stored there beyond over-rev events.

Below is one that made the rounds on Reddit:

Well damn

Since they can see that the ECU was touched, it'll be logical to assume that the ECU was altered to improve performance in one way or another, unless people are modifying ECU for other reasons not performance related.

I agree. Proof of modification of the PCM is not proof the modification caused the failure. In fact, without fully diagnosing the failure they have no evidence the PCM modification caused it.

How can you know what caused the problem if you don't know what the problem is?

I'm not dismissing anyone from needing to take responsibility for tuning, but there was blatantly no evidence to blame the modification. They have no right to cancel the warranty given the lack of evidence they presented.

I almost want to say that is fake, and a scare tactic. There is no way the deep dive required to make a full determination to cancel warranty like that was made simply for some difficulty shifting into gear. It's not like his engine or tranny blew.

Edit: It gotta be fake. No typos from the service advisor?

Before anyone jumps me, bear in mind it is absolutely possible an issue as described could be due to a failure not caused by tuning. A faulty shifter linkage, a defective synchro, a bad shifter assembly, a sticking clutch, faulty master or slave cylinder, bad throw out bearing... The list goes on. I find it outright sickening (and potentially illegal) they didn't complete a diagnosis before throwing it in the customer's face.

That sounds pretty logical.

No KTuner or Hondata decals. Got it. Don't do anything stupid and don't abuse the car. Got it. Keep the car maintained with good fluids. Got it. Anything else I'm missing?
I have a question when u say dont abuse does that mean I cant floor it to feel my ktuner power?

For argument sake, let's say it's not fake. From reading the notes, it doesn't look like they are blaming the gear lockout on tuning, although it may be implied that additional power from being tuned could have damaged the drivetrain. If this is real, there could be more to this story, for example there may be a history of this person messing stuff up and getting warranty repairs. If I'm blowing engine components, eating thru clutches etc Honda might become suspicious.

Anyway, I'm not sure how it can be verified if this is real or not

:topic:

While some good conversation is going on here it I would say about 5% of the posts here are directly about the topic at hand, while many but not all of the rest are somewhat related. Please consider making new/separate threads for any new topics. This invites others to join in with relevant information, when available. It also helps out future searches, for the few that do actually use the search tool. :)

Flooring it would NOT be abuse.
Ok so what is considered abuse ? I recently got me ktuner but kinda scared to floor it cause I saw some post about things blowing up the most I've gone is around 4500 rpm

One thing I will add to this thread as I am a service adviser myself. "Lying" or misrepresenting communication from a manufacturer to a customer is a huge deal. Everything on the ticket is able to be presented in court and is legal paperwork between the customer and manufacturer.

There are some precautions to take if your car is still new or if you are newly driving for the day regarding high-range RPM. Otherwise, outside of temperatures, the higher the RPM the safer you are to do things like floor it. Tis better to floor it at 4500 RPM than at 2500 RPM.

When I click on the image, it opens a new tab and all I get is "Not Found". Has the original post been taken down?

EDIT: I removed all of the crap after the "?" in the link and it worked. :)
