    Question about speed limit signs

    So I've played around with what I would like to have displayed below the digital speed display, I think I've settled on the cool little speed limit sign. That's pretty cool. That being said, I've noticed some streets are not listed and some are now wrong where the city or town as lowered the limit recently .

    So the question is, does anyone know about how that works and how that can get updated?

    Re: Question about speed limit signs

    Continuously displayed speed limits on the Instrument Cluster are a useful way to minimize being "awarded" speeding tickets.

    For the latest speed limit changes, you'll likely need the latest GM Nav map update (which may not be current if the road speed limit was recently changed before the update data was collected. . .)

    The latest (2019) map update is available here to bounce against your current map rev displayed in CUE: https://gmnavdisc.navigation.com/pro...en_US/GMNA/USD

    I've also noticed how it seems to know the current weather and if it is inclement weather it will give you a warning about icy road conditions on that same display.

    The 2016's have a bit more range than the 2014's, and if you only drive around town without the heater 50 miles is definitely achievable. That is about the max, unless you hypermile and do things like no climate control and 20 MPH max.

    All GMs do this for about the last 10 years. It is just the rate of temperature change - doesn't tap into anything special beyond that.

    That's great stuff CCC, that's very cool I can just USB stick it, as well as the rest of my world using digital consoles and everything else. Seems like a fair price. I honestly don't believe someone came to Priusville/Subaruland and wrote down all the changes but it's cheap enough it might be worth the try!

    It's super cool that some cars can be updated this way instead of perhaps some crazy brand and vehicle specific gizmo! I would imagine that it's mostly CD/DVD updates before that, at least that's how Jag's map update works. And definitely more expensive...

    Thanks again!

    Yeah it's pretty moderate here in Priusville so I haven't had to use the heater much and have only limited use on AC. I don't floor it on take off and coast a lot, controlled spurt pedal techniques and then coast, but never impede traffic of course. Try and never use the brake replying on the heavenly regen paddle for almost all braking. Did I mention that is the greatest invention ever? I think I did... . Almost always get 47 to 48 electric miles, on a BAD day I see 39, not so good day (a lot of take offs) maybe 43...

    When I bought the car I powered it up and the range said 27 at full battery - yikes! I thought well there's a pedal stomper for sure, but maybe a crank the heat type/colder environment from Ohio where it came from. The lifetime stats at 37,000 miles was only 62 MPG so whoever had the car most likely had a long commute I would assume and lots of gas miles? After 3000 miles I only have it up to 69.x right now.

    But what's funny is, I don't really see changes when I turn on the climate. In my i3, the second you turned on AC the range dropped like rock and if you turned on the heat it would dive faster than a V2. 20 mile+ range hits not uncommon when it's in the low 40's or under and crap for range. In my ELR I haven't seen real cold weather yet, but haven't seen the range meter move at all when I hit the AC on high at maximum climate control...is that right? Maybe it doesn't care until it gets real cold or real hot, but right now it seems like it just doesn't care... not complaining!

    All that being said, we're supposed to see 96 here in a few days, we'll see if that range meter takes a hit.

    Re: Question about speed limit signs

    AC is not bad - minor reduction in range. The type of compressor used is rather efficient, but it does sound like a jet engine when it is hot and you are traveling at low speed. It tones down quickly, after briefly going into orbit.

    Heater will lose about 30-40% of range, until temperature drops to 32F and the engine kicks in at low RPM to supplant heat and range.

    You mentioned you got the car from Ohio - did it happen to come from Cole Valley Cadillac in Warren?

    Re: Question about speed limit signs

    The ELR came from Germain and they were great to deal with.

    So after the coffee shop yesterday I decided to go see my Mom which is a 85 to 87 mile journey depending on restaurant I take her to. This time I thought I would try to beat my MPG record and electric range record. No cheating - no mountain mode , switching to Hold mode and going back and forth from D to L when it was deemed necessary, no low speed stuff. No cheating either like using the engine for going all the "ups" and coasting on all the "downs". Real world driving, lots of little hills, some big ones, lots of traffic and this time I really hit a lot of lights which sucked. I took off in rush hour too right at 5pm which made it extra sucky. About 10 miles freeway driving at 60 and engine on, 10 miles at 35 mph, all the rest 45 to 55 MPH. No impeding traffic. I was able to beat my record by about 10%, and get 52 electric miles in real world sucky rush hour driving. AC was on about half the time in medium mode, and I had the windows open the rest of the time. I didn't even think about the fact that windows down would effect my lovely slipstream until I got home.

    Here's the energy used screen ELR energy screen.jpg

    Basically my biggest effort this time is driving by wire and really watching the Kw being used on the right side of the dash screen. I try and not use more than 20 Kw when it's laboring and only up to 30 Kw when climbing a hill. Of course if it's too steep you have to Hold mode it...

    Here is my lovely Dash screen this morning AFTER a 5 mile trip to the coffee shop...

    A new record for me... but I don't want to get into the habit of doing that as it takes away from just enjoying the car...
