Modding the driver info display?

mannyz · 07-23-2009, 01:37 AM

I will like to see when this is ready, the Z is missing a lot of information and I think the Clock in one of the gauges was a waste of space

I bookmarked this a while back, I believe the idea came from reading travisjb's journal. Replacing the clock with this for accurate oil pressure and water temp would be nice: SPA Oil Pressure Water Temperature Gauge DG 200

Spa makes good gauges. I would like to ditch the clock and install a real oil pressure/water temp 2-in-1 gauge as well. If you install it,; I will gladly copy your DIY

I generally keep Water temp, Intake temp and short and long term fuel trims up on mine all the time.. Handy tool!

Sweet - the Z was the starting ground for this technology (OBD) with the Datsun 280Z! Too cool

I know these are numpty questions, but guess what - I'm a numpty

Do you just use it as a link between the car's OBD and your laptop? If so, where does it actually go?

Yes, it's basically an OBDII (including CAN, so hopefully our cars as well, which use CAN SF) to USB adapter basically. Once you have that hooked between the car and the laptop, you can use any number of free tools to monitor car data, or write your own software for it (or build a scangauge-like custom device to do whatever you want on an embedded platform).

IS the release date for the 370Z with manual transmission, sport package been set yet?

Plugs into the OBD2 port; X-Gauge function has the ability to query all CAN outputs if you can come up with the Hex codes. The Z runs CANSF mode on the scangauge which has a fair number if data points documented and accessible..While I have seen these kinds of modifications to existing screens done on other cars (the EFU for Audis being one example), it generally takes a brand enthusiast who is highly skilled (and motivated) and if it ever hits the market( 4 years in the case of the Audi), very expensive...I wouldn't hold my breath on this!

OBD is open source though, so knock yourself out!....:-) On-board diagnostics - Wikipedia, the free encyclopedia

Info available that I can pull up on mine (any 4 at once):

TPS: Throttle position sensor 0-100%
fIA: Intake Air Temps (Temperatures at the intake manifold)
fWT: Coolant water temperature
HPR: Horsepower (Looks to be pretty accurate from initial runs on several cars)
VLT: System Voltage
IGT: Ignition timing (advance)
LOD: % Power request
Closed/Open loop: Fuel management and transition point from O2 control to WOT
STF: Short term Fuel trims
LTF: Long term Fuel trims
OX1: #1 O2 sensor output, 0-100
OX2: #2 O2 sensor output, 0-100
MPH: Digital speed reading from Speed sensor
RPM: Digital RPM’s
MPG: Miles per gallon
GPH: Gallons per hour

Trip Data: Fuel economy, Fuel used, Distance, drive time, Avg. speed,
Distance/time/fuel to empty, ETC.

As a Scan Tool It can act as a Code reader and eraser,Determine Readiness tests, Turn off and clear CEL’s etc.

ScanGaugeII - Trip Computers + Digital Gauges + Scan Tool

I generally keep Water temp, Intake temp and short and long term fuel trims up on mine all the time.. Handy tool!

Since the 370Z comes without an oil pressure gauge; would the scangauge display oil pressure?

No....Oil pressure, as reported by the stock sensor is On or OFF. You would need a pressure reading sensor, as a dedicated gauge would use, to come up with an electronic reading. OBD doesn't care much about oil pressure..

Did you add a oil pressure gauge to your 370Z? Where is the best location to install an oil pressure sensor. I'll likely ditch either the clock or the oil temp gauge and install either a separate oil pressure gauge or a SPA dual oil temp/oil pressure gauge.

Also, I am thinking on adding a oil by-pass/oil filter relocation kit. Amsoil sell's one for the 370Z. This kit installs via the spin-on oil filter location on the engine. Feed lines go to the remote oil/by-pass filters then return back at the engine's oil filter location.

If a oil cooler is added, is it best to send to the oil cooler before the remote oil/by-pass filter prior to returning back to the engine? I'm not sure whether the mocal sandwich plate is compatible.

Personally. That left tach is my only major gripe on this car...
Its fugly. Its extremely tacky, and so is that 1970's digital watch readout/dashboard microwave scan gauge.
Why couldn't they just leave that gauge group analog???
To me that would be the best fix. 3 analog gauges like the 350z.
Sports cars don't need all the extra blinking lights... leave that for civics. (The king of fugly dashes)

I just picked this up from Travis.
STRI Oil Pressure Gauge... Amber 52mm to replace your clock !

So is it possible to modify the driver info display screen?

alecnet · 03-09-2012, 04:52 PM

I love this idea. Wish I were a programming guru and could figure this kind of thing out. Another option might be to somehow build in one of those scanpro gages into custom cluster that would replace the ugly guage pocket on the left. Might be easier than hacking the stock display.

wstar · 03-09-2012, 05:34 PM

In theory everything the stock gauges and info displays can show us is available on the CAN bus. It's just a matter of someone figuring out all the custom protocol extensions and PIDs to get at some of it. Unfortunately the custom extensions seem to be closely guarded secrets. Some aftermarket guys apparently paid off someone or other to get the PIDs and can show data that I'd really like to have generically available (e.g. brake pedal position, oil temps) for datalogging. I'd kill to know what hex numbers I need to tap into a Android OBD-II tool to get those.
