#574 of 1534 30 Days since Software update
Sep 01, 2010 (4:27 pm)
I, like everyone else, was extremely disappointed after my software update for my 2008 Civic Hybrid. The car drove very sluggish, and I had a very difficult time climbing up hills. Even with the battery indicator showing half full, the electric engine refused to kick in, so I was left with the gas engine only to climb the hill. It had become a safety issue for me, so 1 week after the update, I took my car back to the dealer. They spent a day on it and calling back & forth with Honda Corp., but in the end they said that that this is the way it is and that they can't do anything about it. They suggested me to drive the car for a while for the computer to relearn itself.
Being desperate, I decided to top my next tank of gas with Premium Unleaded. Wow! What a big difference it made. The car took off with much more pep, but at a cost of more $$. The next tank of gas, I switched to the midgrade Unleaded (89 octane) which costs less, and I found that the car still drives with the same pep as using the Premium grade gas. Now after 30 days, I am really loving this car. With the midgrade gas and the computer having time to adjust, the car just drives great. Gas milage has not changed much, and my last tank averaged 41 mpg. This is great considering I live in a hilly area in Southern CA, and it's also summer weather. The extra 2 octanes gain from regular to midgrade really made a big difference on this small gas engine. An extra 10 cents per gallon more is a small price to pay. The car drives much better than before the software upgrade, and the hybrid engine seems to blend in much better than before the upgrade. Just give it some time for the computer to adjust, and try using a higher grade gas.
#575 of 1534 Lost MPG after Firmware Update

I have driven my '09 Civic 400 miles since the secret firmware update (they did not tell me at the time). My mileage has dropped from a 47 to 41 MPG and performance is very sluggish - almost unsafe. Now I wish I had never bought this car.

Trade it....trust me. I did am=nd am driving a wonderful Ford again!
The performance will not improve and Honda will not do anything to fix it. I spent months trying to resolve it, with numerous trips to the dealer and lines of bull.
You are correct. Acceleration is dangerously inadequate. Trade it and never buy Honda again!
#577 of 1534 LA Times

Sorry if this has been posted (I've been out of town for a few weeks including when it came out) but in case it hasn't been posted, the LA Times did a big article (right on the front page of the Sunday paper) back on Aug 15th about the Honda "update" and battery problem. Even though it's listed in the business section online, in the print edition, it was Page One of the Sunday paper (main section), above the fold, where everyone could see it.

Nice dream. Octane does not affect performance in the way you describe.

I agree, the only way higher octane would show improvement, would be if the engine was the high compression type which it is not.

Maybe you can just try it on your next refill. It won't hurt to spend an extra $1 on a tank full just to try it for yourself. It seems to work great for me in conjunction with the new software update. I had the same gripes as everyone else, and was on the verge of getting rid of my car when I switched gas. I think it's both the gas and the the time it took for the software to adjust. Drove about 700 miles since update. I just thought I share.

To verify what happened why don't you go back to regular for a tank to see what happens?
#582 of 1534 Changing grade of gas can help

With modern engines that use variable timing and integrated knock sensors, it is possible that a higher octane gas would require less retardation in the timing, which generally can result in better horsepower.
#583 of 1534 Updated software with no improvement to IMA
Sep 03, 2010 (10:04 am)
I got the software update a few weeks ago. I started having at least daily discharges of the IMA battery in early June even in cooler temperatures and without AC. I hoped that the software update will solve the IMA problems but the 1-3x discharges have continued. If anything, the software update has made it worse because the engine recharge kicks in when it reaches 2 or 3 bars which means longer periods of sluggish acceleration.
I took it to my Honda dealer and they said that the IMA system checked out fine and they couldn't do anything. I repeatedly said that there is a problem despite their equipment saying it was fine, and that they needed to drive my car for a few days. I filed a complaint with Honda and their response was that I had to go back to the dealer and have them test drive it as I requested. I feel like I'm getting the run around. I'm going to see if the dealer will test drive my Honda and then consider the next step.
