With all that technology does this prius have an OLM?

Maybe Norm can rig you one that allows you to input your oil specs like full synth, semi syth or dino and it will customize your OCI.

I love these gizmos. You can never have too much info!

Any idea if this guy messes with BMW i-drives?

Neat stuff. But, man... my Metro is the anti-Prius. Speed, fuel, coolant temp, that's it. Not even a tachometer or oil pressure gauge.

If you and I both get a MIL/CEL come on today, who's going to be able to pull the codes easier? Jackpot! So tell me, what temps have you been running in your transmission lately? Are your fuel injectors working within spec? Is your 12V battery starting to die? Oh that's right -- you don't know. . .

What kind of gas mileage have you been seeing? Also, have you considered doing the plug-in mod?




A Prius seems to exhibit a much wider range of mileage performance than a conventional car, depending, essentially, upon your driving style and how hard you try. Last week, I drove New Orleans to Charlotte NC and back. Since I was willing to trade gas for time, I cruised at ~80-85 mph. I averaged 46 mpg on the way up and 43 on the way back. If I’ve got time and I’m willing to cut back to 65-70 mph, I’ll get over 50 mpg. On my in-city New Orleans commute (10 miles each way, if no side trips), I’ve gotten as low as ~42 mpg and as high as 51, again depending upon driving conditions. Grille blocking will gain 3-5 mpg over non-blocked, if conditions are appropriate (i.e. colder conditions). If traffic is sparse and I can execute a true “pulse and glide” pattern, add 5 mpg to how I’d do otherwise.

Oddly enough, it has a “maintenance reminder” light only. Despite the other clever things the car does (even without CAN View), this is an idiot light – all it does is come on 5k miles after it is reset.

Theoretically, given what I know about GM’s OLM, and the data CV can access, this is entirely possible. I suppose the issue would become how much it would cost a customer to have it built in. Keep in mind that it would also involve a calibration process, which would include multiple UOA (which I already do anyway). Sadly, I doubt it’s within practical reach.

So true.

Well, I don’t know. His company is called Hybrid Interfaces, would tend to suggest he doesn’t. On the other hand, I can’t see why it wouldn’t be “do-able”. I’m e-mailing later today with some follow up questions, and I’ll ask if he can or knows of anyone who does.

Vilan:

Actually, every time I pull into a gas station with 2 gal in my tank, add 10 more to full up (for approx $25) and realize this will take me almost 500 miles, I consider that a jackpot. Especially so since my previous car (a G35) consumed more than double the fuel I’m now using. Since I log almost 40k miles per year, this is big for me.

A thought on the Metro-Prius comparison: other than fuel economy, these are really cars of a different class. The Metro, as you know, is a subcompact. The current Prius (second generation, the hatchback, not the earlier sedan) is actually closer to the Camry in interior volume than it is even the Corolla. In short, the Prius is a larger car that happens to deliver the fuel economy of a very small car. Now, I’m not “dissing” the Metro or Aveo in any way (they accomplish their assigned mission very well), it’s just a different car. I'm not selling Toyotas, but I like to point that out, since some people dismiss the Prius as too small, without ever actually checking out its interior.

Don't you find it ironic that, despite the admittedly advanced technology of the Prius, the display looks like an IBM PC circa 1986?




Remember, these are the aftermarket CAN View screens. The standard Toyota screens are much more modern looking. See the second of the pictures I posted, above. That’s a “native” Toyota screen appearance (I use the selectable tan color, blue, green, and grey are the other choices). So no, the dozen or so Toyota screens do not look like those of a mid-80s PC.

There has been some discussion in the Prius forums about the UI Norm uses. I’ve asked myself. It is technically feasible to equip the CV unit to present a prettier, matching GUI, but the hardware to do so would push the unit cost beyond what most are willing to pay. I suppose it’s a matter of taste, but I don’t find the look objectionable at all. I suppose it would be a bit more fashionable if the CV screens all matched the Toyota screens, but I’m willing to save the money and have it this way.
 
Yeah I get the fact that the CAN View screens are aftermarket and programmed by Norm. I don't find them objectionable. It was just a bit of deja vu to see those screens. Brought me back to my childhood (I'm 29)
 
DD77:

I'm 46, so I remember those days well. Giant floppy disks, machines that booted therefrom, and all the antics required when using DOS and only being able to run one program at a time. I have the "distinction" of having checked into my first operational squadron during the same week the admin shop got their first PC (it was 1986; all the desks had typewriters on them). It was a 286 processor desktop, with a green monochrome monitor. If you had parked a brand new, bright red Ferrari in that office, it would have received less attention than that computer did. Hey, at least CAN View doesn't require you to strap an IBM Selectric to the top of the dash!

Sounds like you are getting as addicted to tuning tricks to finding those extra MPG's as some get about tuning tricks to finding those few extra HP.

It's just the other side of the coin as far as automotive performance is concerned. I like them both!
 
Absolutely! One of the truly entertaining aspects is learning how to drive the car in a relatively normal fashion (i.e. without extreme Prius antics) while still optimizing (if not maximizing) fuel economy.

Although it's only been installed a couple days, I've already found a practical use for the CAN View unit (yes, that is a dig at Mr. Bottilaw...
wink.gif
). As you can see from my recently posted UOA, my car has fuel dilution issues (apparently common with the Prius, but in my case anyway, not harmful). The unit provides both fuel flow and injector performance data. From this, I've noticed that for whatever reason, at many times when the gas engine is "spinning" turning, but not firing, there is a very small amount of fuel still being injected. I theorize that perhaps this is to provide the cats something to act upon, perhaps to keep temps up without actually firing up the engine. And of course, it may be part of why gas builds up in the oil. Still investigating though.

Interesting.

I think it must be an emissions thing. Presumably the gasoline would vaporize if injected into a hot cylinder but not ignite. The fuel/air mixture would then be pumped out the exhaust and be ignited when it hits the catalyst....thus keeping the catalyst at the optimal temperature for efficient emissions performance. In this way, the catalyst wouldn't cool off, triggering the richening of the fuel mixture many fuel maps apply when the catalyst is cold.

That's my guess anyway, but I'd be interested in the results of your investigation.

Nope, the standard digital package in the Prius gives you the information that you need to modify your driving style to minimise fuel burned. Every 5 minutes, you can see exactly how your behaviours affected mileage.

Every car should have something similar.
 
What operating system does that computer run on? QNX? I find the whole computer in the car that runs everything via touch screen quite interesting...

I'll see if I can find out for you.
 
It is preety cool! I am still waiting for some of these "Super Capacitors" to hit the market. Supposedly they have 25 time the power density of current metal-hydrid battery technology. So it would even blow the litthiam-ion battery's Toyota is planning on useing in it's next Prius out of the water. When they become available this addition/substition in an exsisting Prius with some software upgrades would yield 100MPG with out doing anything silly like makeing it a plug-in electric car.
 
I like it but have a small issue.

I like cars to last 15-20+ years. My MB diesels are great examples of efficient vehicles that give good fuel economy and great service life/longevity.

However, those cars are also very simple, despite being super-well engineered luxury cars.

I worry about having an LCD TV screen in my car, which will last how long??? I cant say... can anyone else?

Will it still be easy to view 12 years from now? Lets not forget that regardless of how efficient a vehicle is in the here and now, it takes a LOT of resources to produce it, and to ultimately dispose/recycle it.

So I worry about gadgets like screens in my car dying on me before Im ready to trade the car in.

Too much information is never a bad thing. I have a similar program, and I run it from a miniature Sony aptop that is from 2001. Not as cleanly integrated, but if it breaks, Ill get another mini laptop used. I can take it out of the vehicle in the very cold or hot, can use it for other things, and can replace it without pulling the dash.

VERY cool set of connectivity to your vehicle and information transfer. I just wish it would not be at a significant cost as one of those 'makes the car worthless before its time' type of 'consumable' items that they put into vehicles these days - and Im not taking battery packs or motors!

JHZR2,
I'm driving a fly by wire direct injection, computer controlled turbodiesel at present. I love it, and love its economy and performance (compared to my similarly sized same capacity petrol engined SUV made 13 years previously).

I still look longingly at the old MB diesels, particularly as I drive past fish and chip shops.
 
'computer controlled' seems to be OK. ECUs and whatnot seem to have #@$%! longevity, and though sensors die, their payoff can be enormous in their lifecycle.

However I still worry about having an LCD computer or TV screen die on me prematurely... does not look like itll be getting replaced easily... or without removing the dashboard!
