Is it true.....

[CJL]

I have been told that on the DC5's the ecu records the highest you have rev'ed it out too :shock: , also it can avoid your warranty if you have stuffed something for revving it to eg 8000 or some crap :P

I could smell bs when i was getting told but i thought i would confirm it, just to be sure....

[VTEC16]

I can smell it too!

[JSL]

Well I know alot of new ECU can keep record of highest recorded rev.. I had that on my AUDI... But the other things who knows..

[Javed]

Just reset it before you take it back to honda ! :P

[A'PEXi]

is there a way of checking urself?

[Tofu]

i think there is a log somewhere
it's not something they will check and i think it takes some time and effort to check it

why would this be a problem if your car is made to rev its nutz off?
unless the ECU can also log information about how often you rev to that certain point

How hard you drive your car is NOT the problem.

What they would be looking for is..
When the car was purchased new, they tell you not to rev it past a certain RPM until you have done a certain amount of kms on the car. They are able to see if you have broken the Honda Factory advise, which is waranty voidable

Honda Australia also know exactly where the Rev Limiter is - the ECU can;t go past a certain RPM. but we all know that there are ways of breaking the Rev Limiter set in the ECU - basically, the ECU record if you break the Rev Limiter, which means you have used a non honda device - which also voids your waranty

This is for the waranty on the engine - the engines are relatively fragile, and have been known to die in a short time - this is a good way for honda to protect themselves using technology from the people that don't follow their guidelines and waranty rules

Not entirely true:
Theres a rev limiter which stops you from revving past a certain limit, and then theres ****ing up an upshift/downshift. If you miss a gear and shift from say 4th to first, your rev limiter isn't gonna stop the over-revving of the engine.

OT: a Porsche GT3 in the states had its ecu transcript recorded and a driver recorded over-revving to 14k/rpm for a brief second. no damage whatsoever! I know what my next car is gonna be... :p

Sorry, I left that bit out because it doesn;t really apply....
This was how my Honda Dealer explained it to me

ahh... :)

Does resetting your ecu reset all your driving logs/rpms/speeds, etc.?

[McChook]

apparently (don't know how true this is) there are 2 different resets.. one is the easy to find, the other is the failsafe for Honda....

how did this guy manage this:

when i've done that in my car, as u said, my limiter kicks in :?

Possibly because the RSXs are made in the US with different stuff
Lots of maybes

as for Pre 2000 cars I have never heard of such logging of driver data, other that fault codes. nor have I ever seen that feature in the PGMFI tester ( that dealers have ).

Niether have I, only saying what dealer told me about DC5s, which are post 2000

hmm. When i picked my car up from honda dealer i asked the guy how long do i give her till i can play.. He just said you can do it right now no need to wait till u get to a certain amount of km's. He also said i tell this to every customer as far as im concerned as long as the engine starts when u pick it up u can go nuts :|

[spite]

You can go nuts however having owned 2 DC5R's now and running the first one in hooning around the streets and the second one driving Miss Daisy for 5000+k's .... I can tell you which way is better.

your 1st one will be more responsive.

Iv done this test before. dont forget Honda engines are run in at the factory.
