986

I am looking to hook up some basic data logging to my 964.

My preference would be to connect through a Bluetooth OBD link (I have a DL1, but would like to move to a wireless setup).

Would a 19-pin to OBD2 adaptor (e.g. Bergvill's) output a standard OBD2 signals to the Bluetooth transmitter, and what signals will be available? (e.g rpm, temperature, full throttle, off throttle?) I also understand others e.g. throttle position will not be available.

Thanks for your help!

964s are ODB1. I'm not sure if they hook up the same. Probably won't be able to get as many parameters either.

Best that you can do is the obdplot routine available here: http://pcbunn.cacr.caltech.edu/jjb/p...64-Porsche.htm

You'll need Tore's t-obd to use it. You can get volts, rpm, timing, injector pulse, temps, etc. But the resolution is *very* coarse.

What are you looking for?

Thanks. I am looking for at least rpm for a shift light (using my cell phone). Since the light will blink ~500rpm from red line / rev limiter, does t-obd gives enough reolution?

I had a DL1/Dash 3 set up in my old Boxster. I got rpm (which also feeds the shift lights on my dash), TPS, and brake light (not pedal pressure) in additional to GPS and g's. I was only using only 20% of my logger's (DL1) capability.

Since cell phone apps can already log GPS and g's (and integrate video syncing), I am trying to understand how much of the other data I can replicate without installing a dedicated system.

Thanks for your help!

Shift light would be cool. I'd like to have a gear indicator.

Always wondered if I could hook up an HUD to the OBD1 - OBD2

Nothing will read data from the 964 motronic other than hardware that is specifically designed for it.

Not sure if I'm missing something, but why do you need a shift light unless for the gimmick? The rev limiter works perfectly well.

The rather old software OBDplot did a similar thing: http://pcbunn.cithep.caltech.edu/jjb...64-Porsche.htm
OBDPlot with all the necessary drivers is included in the downloadable zip file for my T-OBD.
Off-the-shelf OBD software/"readers" will not be compatible with the 964 Motronic, wireless or not. The OBD output data from the 964 Motronic unit is not fast enough to be a reliable RPM shift indication.

Cheers,

Good to know. Thank you!
