My LCD screen project, boost, WBO2, Knock, etc

PSI Sensor= Int. Use internal pressure sensor 0.0psi to 36.3psi. Note that it does not measure vacuum.
PSI Sensor= Ext. Use external 4.0 BAR greddy pressure sensor (vacuum to 43.5psi) .

If I'm reading this right it appears I can use an external pressure sensor but I'm not finding any instructions on hooking that up. I was wondering if my old greddy profec could be hooked to this thing and show vacuum. The greddy doesn’t control boost anymore but it still reads boost on the screen.

If you disconnect the internal pressure sensor and hookup an external pressure sensor to it instead, it will work. Kinda difficult to do afterwards, that's why the "newer" version will have an external connector making it easier to switch between internal and external sensors. And no, don't use the aux input.

*WHITE <Analog Output>
Connects to any auxiliary unit that accepts a 0-5 volt input.
*BLUE <Serial Output>
Connects to a RS-232 com port for hyper-terminal data logging.

Hey real quick, I need to use the analog output right? or the blue RS-232 com port?

Analog output.

I don't think it is but I'm going to use the aux for wideband so I guess I can't do it anyway.

The wideband is just one wire, and the aux is just one wire, so there's no compromise. Each function is available.

OK, I see now, since they were on the same harness I thought. well lol nevermind. I think I have it now.

I wonder what software I should be running on my unit for my 1998 JDM GTO, AFAIK the later JDM ECUs were not flashable like the USDM equivalents so maybe they are different and I should be using the 1991-1997 software. I will try the 98/99 version first I think...

Anybody running AEM wideband? How did you set it up? I cant seem to get mine to read correctly.

When you make it AEM compatible will I just be able to plug into the serial port like the 19 port daisy chain Serial gauge that AEM makes? Because that would be pure bad ass.

Are these available for sale again yet?

Nope, it would get expensive to keep adding features. You have to use the analog 0-5volt wire that represents the AFR.

JasonY: I'll have new versions probably available in 7 weeks or less. I need to test the new design thoroughly.
