Does obd2 stuff show boost on FI apps?

snowsurfdirtx · 09-11-2013, 08:37 PM

Can you pull boost from OBD2 style gauges? I know some guys run them in other cars, but not sure if you can in ours

I'm trying to keep the number of gauges to a minimum. If it works and is accurate, I'll run a multi boost/AFR gauge thru OBD2 and a separate oil press one

Sub'd for the right answer

IIRC, one of the standard Mode 1 PIDs is intake MAP but the 370Z doesn't report it. I assume the ECU has that info and it's just a matter of knowing how to ask for it.

I do not believe so. Even if it was possible, I don't know if I would want to trust it over a good quality, aftermarket gauge.

Yes, there is a built in PID for boost/vac as a standard parameter in the Torque app. It still runs on N/A cars, just with vacuum (obviously).

Thanks for the help

That's what I figured, since they advertise most of those obd2 products as being able to show vacuum and boost I wanted to double check.

I'm gonna just run a boost/oil pres 2in1 gauge and a separate small rectangle AFR gauge then. keeps things tidy and I don't have to rip my dash apart

I have a PLX Kiwi WiFI module with my iPad using DashCommand.....it reads something in the "boost" section but the numbers are way off; showing super high as compared to the Defi gauge. My boost is set at 10psi, but the DashCommand/PLX set up is showing like in the 20s.

Is it 1 bar (14psi) high?

FireDan50 · 09-12-2013, 02:25 PM

I'll have to double-check the numbers on the dash command next time I'm out with the car. I just remember having it on and seeing way high psi numbers that did not match up with the Defi gauge.

Chuck33079 · 09-12-2013, 02:29 PM

Since it's not used to positive pressure, could it be reading atmospheric pressure+boost level?

hmm that could be the case. or its just totally confused

I think I'm going to run a Defi red racer on the pillar, and an aerotech analogic w/ oil pres and AFR right above it. warning lights for both afr and oil pres with that one too. pricey, but keeps it tidy and i still get that sexy, sexy defi boost gauge <3

mfeinst · 09-13-2013, 12:01 PM

Yeah, I'm gonna get Defi gauges because they're Defi gauges. Advance C2 ones are gorgeous but $$$$$

FireDan50 · 09-13-2013, 12:43 PM

Just confirmed my PLX wifi/Dash Command set-up does not work with boost. The difference in boost pressure and vacuum is totally different than what my Defi gauge is showing; its showing both higher and lower measurements and totally not right. Everything else is good so far; IAT, water temps, etc.

Planning on running the PLX Multiguage display with boost, AFR and trans temp modules installed in the stock clock location. Much cheaper to install then 3 separate gauges in the stock location.
