Installed a New Driver Info Center Next Day. LOVE IT

[Lightning 95]

Thanks to all of the previous DIC posters. Hoping the posted info was correct, I ordered the switch, and panel from my local Chevy dealer yesterday afternoon, and got a call at 8:15 this morning it was in. Just installed it a few minutes ago, and it took less than 10 minutes, and works GREAT! Easy to figure out having the new panel on hand what to do with the clips. Just popped the left clip out, and then using a credit card released the 6 clips to the right of the vents, and popped the last one out. Sure enough the plug was right there so I test the switch, which worked. Then snapped it into the trim panel, jiggled it around to get it lined up, and snapped everything right back into place. My old panel was scratched so this was an awesome upgrade, that was simple to do, and cost $173.18 plus tax.

Nice!! my new panel and switch are supposed t be here tomorrow. Same problem/issue, one in there has a few scratches and the color looks a bit dull.

I wished this could have been a dealer installed option 10 years ago after driving my 08 LS Silverado with only the odometer button. I'm guessing it was the same setup as the PPV. BTW if you want to save some money, the trim piece is 3 separate pieces, and it would be super easy to just get the little left hand piece off of a junk panel, and fit it back on. It is just 2 small plastic tack welds.

Getting the DIC on my 13 ppv I was able to get the total fuel used in addition to total hours.
74344 miles
9990 hours=7.44 MPH avg.
9040 gallons=8.22 MPG avg.
I should be able get the average speed up for sure, but probably not the fuel.

I noticed that too... plus it shows the pressure for each indvidual tire, which is handy.

Mine has:
72,230 miles
4,990 gallons of fuel
2579 hours running (I expected more hours on it.)

After installing the dic, I've been able to improve my MPG quite a bit by being more conscious, because I'm able to monitor my average MPG now. I don't always need to be in a hurry to get someplace early, which I usually am anyway!

I like it too, there is one info item: "INST ECON V8" and I have no idea what that is, and it says 0

Anyone know what it is?

Mine only says zero when I'm not moving, otherwise it is reading different mpg all the time based on throttle position, and engine load. I'm guessing if you still had AFM it would also toggle between V8 and V4.

I haven't investigated it on the Tahoe, someone here can probably confirm. But a lot of manufacturers associate something like this with injector duty.

I have to see what that does on my next road trip, and ... what is AFM?

Uhg, do a search on here. Active fuel management.... shuts of 4 cylinders to save gas. Kills lifters and cams.... terrible terrible terrible

Ah, that, I heard "these Vortex engines" have that, is that something that just works by default, or does it need to be activated?

I would guess they may have tuned it out with ppv/ssv tune(do they tune those diff from civilians) but i would guess that the engine internals are still there. Leave the dic on that setting an go for a ride and eyeball the info, especially on a down hill that you take your foot off the gas and see if the v8 goes to v4.

I'll try that. I do know they 'tune' them differently. In the 'specs' I read that there is a "federal emissions exempt" for a lot of those vehicles, resulting in 10% more HP and 10% less fuel usage.

RPOs:
NC7: EMISSION SYSTEM,FEDERAL OVERRIDE

There are a few more emission RPOs

 

[CrashTestDummy]

All the NC7 code does is basically default the emission system configuration to the more stringent system, like what is installed in Ca, NJ, Maine, etc. So if your vehicle has the California emissions RPO code, YF5, it is exempt from the federal emissions, since it is Ca. compliant, which is more restrictive. Merely a 'book keeping' thing:

http://www.gmfleet.com/content/dam/gmfleet/global/master/nscwebsite/en/Home/Resources/01_images/2015-model-emissions-bulletin.pdf

While the tune may be different between the federal and Ca., etc., tunes, ALL of them, from GM, will still have AFM activated. Most Departments will keep this tune, since a retune by the Department motor pool will void warranties, especially if the AFM lifters fail, and the AFM has been disabled. That's an expensive fix that NO Department wants to pay for.

If AFM is disabled on your truck, either the Department did it after the truck ran out of warranty (unlikely, as that's just extra hours spent working on a vehicle that's really not necessary, especially since that vehicle may soon be retired), or, more likely, there was some party that took possession of this truck after the Department was done with it and tuned the AFM out.

I think my wife sees that number and tries to get it as low as possible. I mean, low score wins, right?!?

When I get behind the wheel, even when driving to the store, I usually put it back in the garage a few tenths higher. I'll turn to her and say 'your MPG is now 15.6. Your welcome.'

That’s actually pretty funny, i had it up to 17.6-18 when i parked it the garage the other night, it was 13 this morning when i got in....she kills me

 

[domoarigato]

do you have a parts list for this? was it just the switch and the trim panel you added?

 

[swathdiver]

I'm always about 2 mpg higher than my wife, she speeds everywhere.
