From the web site, the 3700 series are thinner, have 5" screens, voice commands, landscape, or portrait viewing, next turn screen maps. I'm guessing they will work with the OBD HD. Mark
Never mind, I found a write up on it. I believe that I will just stick with my current Nuvi and wait for the 5700 to come out. By then you will be able to talk to the GPS and tell the HD to "Run a systems check to determine if there is a warp coil breach in cylinder numper 3". :yesnod: Jim
I just figured out how to change the gauges You can change what is displayed, and where it is displayed. Air intake temp. is not that important to me for regular driving, so I swapped it for voltage. Mark
Was just giving the 3700 a closer look. I bet the Dragon would look really cool in 3D. Guess I'll have to wait a year and then I can get a 3700 cheap. Jim
I noticed a couple of interesting things, at WOT it says it's only open 76% no matter how hard I push the pedal down.... And 15% at idle while stopped and only 22% going 75 mph on the hiway.....
This sounds cool, glad I have not bought a GPS yet, nice to have one I can borrow from work. I was planning on getting one soon and I was thinking Garmin, now it's Garmin for sure.
Now a new set of questions have come to mind. After changing my tire size the information given by the speedometer is off and so is the mpg. Of course they were both off anyway, so it doesn't really matter. Mark, I know you have 205 tires, so is the information from the HD still way off? How does Eco Routes work? Will it give you good time/distance info from its own information (ie speed on the GPS was always correct) or does the HD connection to the OBDII port mess that up? I just wanted to know if I had Eco Routes (minus the HD) could I get real distance traveled infomation? Jim
I was kind of expecting to get a oil pressure gauge, not there I figured out how to swap them around too but have not seen, if you even can, to get other data points You guys?
Not sure what you're asking there, Tim.... But no oil pressure gauge, you got what you got......but that's still about 19 parameters, right?
You got my question, were there other 'hidden' gauges other than the ones that come up when you sync up for the first time such as oil pressure. It is pretty cool but like most of my toys I always want MORE! waah waahh Thanks guys!
OK, you guys have covered Tim's "oil pressure" thing, so how about the questions I asked????? :incazzato: Jim
I don't know. But my guess would be the GPS would be more accurate. Not sure if the OBD overrides the GPS speed read out. Mark
Sorry for the hijack Jim I have not used that feature of the EcoRoute. I got it mainly for the gauges
I can truthfully say the are not to me anymore Mark. None of the reading are right, so I switched the read out to miles left to fill up and don't watch that much. I was interested if Eco Routes would give me the actual miles traveled as I think I just extended my matanance package by a few miles. Jim
That, and the mileage to next service change all the time, depending on how much the pedal on the right side is used Mark
Been messing around with the gauge choices and checking out the 'intake manifold pressure' The readings are odd in that in any situation other than WOT you get a negative figure in 'inHG' units or inches of Mercury ie '-8inHG' at O and WOT you get a figure in PSI. I've been seeing in the range of +3-5 psi I did a Wikipedia lookup on this and got - 'In automobile racing, particularly USAC and CART Indy car racing, inches of mercury was the unit used to measure turbocharger inlet pressure. In older literature, an inch of mercury based on the height of a column at 60 °F (15.6 °C) was common.[1] 1 inHg60 °F = 3,376.85 Pa In English units: 1 inHg = 0.491098 psi, or 2.036254 inHg = 1 psi.' Got a couple of questions around this - Where is this Manifold Pressure taken at? the MAF? That sensor right at the turbo inlet? - Why does it go from negagtive inHG to positive PSI - Is this the same as turbo boost (doesn't seem to be)
When the turbo isn't pushing air, the intake manifold pressure will be a negative number, when the turbo spins up enough to overcome regular atmospheric pressure, the number will go positive. You can still have a negative number even when the turbo is boosting, if the pressure it's making is not above atmospheric pressure. the inch reading is vacuum, the PSI reading is pressure. I don't know exactly where they take the reading, but it will be after the turbo, probably in the intake manifold itself.
