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

Can I just hook my 0-5v wire from my AEM wideband to this thing then set the lowest and highest the gauge reads and I'm ready to go?

Should be able to. Thats how I set my LC-1 to it.

Good, thanks again

Hey on the little graph of boost vs rpm, what does the graph start and end at? Does it start at 2500rpm? And what is the max boost reading on that graph, 20psi?

It starts at 2400rpms, ends at 7000rpms and increments by 200. The max PSI is 17psi (8 pixels high, 1 pixel in between two characters and another 8 pixels). Between each character it is separated by 1 pixel. On these character LCD display, there is no graphics, but I'm using some tricks to make simulated graphics.

Also do not be alarmed if your boost appears bumpy. If you're at 13.99 PSI, 14.0 PSI, 13.99 PSI it will show up as a ripple as the software is very simple. One pixel for 13.00-13.99 PSI, a different pixel for 14.0-14.99 PSI.

A HUD requires a special windshield (special coating). I can see that getting expensive pretty quick.

Those use different windshields, but I'm not so sure it is necessary. the Corvette guys swap in HUD to non-HUD cars all the time and have no issues. Might be better calarity, but it still works and they are quite happy with the result

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.

Hook it into the aux line I believe. It should be somewhere in the instructions.

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.

*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?
