"To correct the ignition timing issue. They replace a knock sensor, remove the intake manifold and replace all the seals, and correct the timing. The car pulls considerably more smoothly through the rpm band. It is all under a TSB, and for me and for everyone with an 09 should be free.

Engine Pings During Moderate to Heavy Acceleration
SYMPTOM
The engine pings during moderate to heavy
acceleration.
PROBABLE CAUSE
The PCM software, combined with knock sensor
sensitivity, may not adjust the ignition timing as
expected.

damage. Some engine ping is a desired characteristic
for optimal performance and fuel economy.

Replace the knock sensor, then update the PGM-FI
software with the HDS. If you’re working on a vehicle
with A/T, also update the A/T software.

Just want to get some feedback on if anyone has done to our cars yet, or even if this info is true. I know the engine pinging was a big issue with our cars so hopefully this news is positive.

Hm, and I wonder if I can have the dealership do this for me even though my car doesn't experience the pinging. Im down for a smoother acceration pull especially if its free.

haha i saw that post on that other site as well. and +1 on wondering if the dealership can do it even with no pinging, cuz i am experience no pinging but i kinda want to do this lol

ressling

I did it on mine and it resolved the pinging

defconskylude

what does engine pinging feel like?

there are times when im running 60-70mph and it all of sudden my speed de-accelerate and then immediately accelerates within 1 second.

ed_423

haha people said its really obvious, so either im too dumb to notice or my car got lucky and does not experience the pinging

I got my ECU reflashed but they did not replace the knock sensor. According to Honda, Acura Victoria closed, the first step is to do the reflash. If that doesn't fix the problem then they replace the knock sensor. Needless to say my car will be going back in to have the knock sensor replaced.

As for 32mpg...I'm using on average 10L/100kms.

I wonder if I should put the factory intake back on.

i got this knock sensor and ping shit fixed.. and acceleration was anything but smooth for a good month.. its starting to smooth back out now.. but it still has its jittery days.. it was actually more of a inconvenience then it was a convenience.. I'd rather had the pinging then the moderate acceleration issues I have now.

Dealership says thats how most hondas drive and oh well they can't fix it

wow 10/100km... do u do lots of in traffic driving? i must have got lucky with no pinging issues here.. my car seems fine with smooth acceleration.. mind u my car is at 75xx km, but i a mix of back to back to back traffic, and highway speed driving, and im getting ~8.2/100km, im in calgary btw

Luchin

I think I just like the loud pedal. My wife gets about the same mileage as you do and she does mostly city driving here in Victoria. I have gotten about the same as you but I have to drive like my dead grandmother f...ks doesn't appeal to me very much.

Sorry in advance if the dead grandmother comment offended anyone. It is my grandmother I am refering to after all. LOL.

im not goin to lie...my fuel consumption is always in the 10.6-11.6/100km range lol. But then again I have 19" wheels on and enjoy spirited driving atleast once a tank.

ressling

correct in that it is a knock sensor replacement and ECU reflash to fix the pinging. My pining was more of a noise complaint on my part. Other than that, I'm happy.

hmm pinging? what is the sound of that noise? I noticed that my acura makes like a pretty loud idle sound via exhaust pipes.. its kind of like a low, rattle, sounds kinda ricey... is that the pinging? I have no idea how pinging sounds like.. can someone direct me in the correct direction please?
