But I also have to admit that I don't know what the hack would entail, so my opinion is just that, an opinion. Henry, do you mean that GM won't want it to happen or that there is no way to hack the software? I find it hard to believe that there won't be a way to hack it to 80% if you want to within a year or two. If I could chip away an extra 10-15% of those highway miles by staying on the battery longer, I'd be at say 43/57 and my average MPG would be in the 90s. Assuming 1/2 of my miles are highway on the ICE and 1/2 of my miles are around town on the battery, I'll average about 75-80mpg. This noted, EXCEPT for those highway drives I never even approach discharging my battery except by choice, as I can charge between drives all day. So in 5 years I'd be at maybe 4-500 cycles. So figure about twice a week I would deplete the battery. Further, I never need to deeply discharge my battery at all except approximately 90 times a year when it would deplete on long highway drives I have to take. This should buy me a 30% increase in EV range.

Therefore my logic is that my battery should not live any less long than a Leaf's even if it went deeper cycle, like 80% of its charge. Despite going deeper cycle, Nissan uses a fan to air cool the batteries, while Chevy uses liquid cooling for its battery pack. The Volt apparently cycles through about 62.5% of its 16kWh lithium battery. The walk through on the website does a pretty good job of getting you through it.Per Motor Trend, the Nissan Leaf cycles through 80% of its 24kWh lithium battery. That about covers it, if you do find yourself in a bind please feel free to post up your problem and someone one here will help you as soon as we can. Yes with the cable you can datalog read the current ROM image and reflash all in one small package. I recommend datalogging your car to see if your hitting knock just to make sure your ROM image you loaded is working correctly with your car.

The scoobypedia website gives you the walk through on how to reflash, and if you have the newest version of ECUFlash then you'll be okay.Īs far as the current ROM in your car that is probably the standard ROM image from the factory, that's why you save it to keep it for future use or to revert back to stock should the need arise. You don't need Engiunity yet, I honestly feel that you aren't up to the task of modifing the ROM image just yet. Okay buy this cable and flash block-> The go here->
