Question ECM Software Update?

I've read some posts on here referring to a software update for either the ECM or BCM that changes how the G2 Insight handles the hybrid battery, and supposedly makes the battery last longer.

As a G1 owner, I've learned that the programing inside the ECM was changed from year to year, and older ECMs are more desirable in the G1 because they're more fuel efficient or something.

With that in mind, if I call Honda and ask about the software update, and supposing my G2 hasn't had it yet, is it wise for me to get the update, or are there potential downsides?

I would read through these threads:

Unlike the software update the Civics got that lowered fuel mileage, this one seems to be neutral. There are also other improvements that make it worth it

That is what Honda tells its customers, for better or worse.

This is the first time I've heard about older modules (ECM, BCM, MCM, a/c driver, DC->DC, etc being more fuel efficient or concerning the later few just more efficient in general.

I wouldn't be surprised if the programming was/is changed much more often than is noted on the paperwork. I seriously wonder what the dealers teach the mechanics concerning the hybrid in the fleet. I do know a mechanic needs a hybrid cert to work on the hybrid system. BUT, as soon as a mechanic hooks the car up to the HDS the hybrid system is accessible to anyone that knows how to progress the screens.

My take on this is that you take your chances with the service dept you choose. Some have praised the update as making the car more to their liking while others have denounced the updates as a shabby way for Honda to comply with the terms of a class action suit concerning hybrid mileage not being even close to its EPA rated MPG, and the updated just makes things worse as a result.

Perhaps others have similar as well as dissimilar experiences/knowledge to share.

I would like to point out that this is about 2nd generation Insights, not first gen or the HCH. I'm not sure how one would be taking their chances with a Honda dealer with respect to software updates. (Except for whether or not you are charged for them) the tech connects and the computer takes over from there. The tech doesn't do anything beyond clicking OK.

It's the 21st century. One has software updates for their computers. This computer happens to be attached to a car. But jeez, even my washing machine has one.

Question



I went to a Honda dealership today *cringe* and asked them if they could check if the ECU had been flashed with the software update. The guy went on about how I'd probably have to pay $100 for a software update, I showed him a picture of someone else's receipt for it where they were charged $0, and we went back and forth about how if my IMA battery failed under warranty that'd be far more expensive to them than if they just gave me the update for free. Basically, it was everything why I hate car stealerships.

But then he's looking at the recall page and finds what I've pictured above, and said it looked like the software update had already been done. Is that what I'm looking at here? Does this indicate the software update has been completed?

I would have asked to see the service bulletin # 14-064.
Looks like that picture pertains to the IMA battery, not the ECU.

Yes that is the software update that US owners got a letter about. Many of us, early on, found out about three others and talked our way into getting those done. We have never been able to find out if those three get downloaded along with the campaign one as a matter of course, or if the tech needs to manually do them. The first three had to do with: how autostop works, how the CTV works, and how the IMA manages hills. (Before the update the IMA would go into regeneration mode part way up a hill) Those initial updates only where available to 2010 and very early 2011 cars. Later ones had them from the factory.

What was the autostop update?

My car appears to be pretty old, it says Manufactured by Honda, 02/'09. Does anyone know if those updates bundled together into the above update?

@Willie:
I found the service bulletin, here's a copy:

If your car does not regen going up long hills, you likely have the latest update.

My 2013 was in for an oil change at the Honda dealer and afterwards on the same hill the car stopped doing regen. Hill regens were annoying because significant additional throttle is required. On the flat at highway speeds I'll get regen at mild throttle especially if the battery is depleted.

I got an update prior to the letter being issued even though the letter does not apply to my year. I believe you get all the current updates whenever the car is plugged in.
