Modding the driver info display?

wstar

This isn't a Tim sort of job

This is a software fixup I'm talking about. We'd have to reverse engineer whatever code is running on the little info display module and modify it.

Someday, probably after I'm dead, perhaps car mfgs will think about releasing code and developer kits and such, at least for the non-critical items like this. Until then it's all reverse engineering

No need to re-invent the wheel!...since the Scangauge does all that....



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!

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

37Z

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

Modshack

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..

37Z

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.

I just picked this up from Travis.
