Volts ??
0.51 25
0.90 49
1.29 70
1.68 96
2.07 120
2.46 144
2.85 170
3.24 195
3.63 255

I think there's something wrong with that data because it's not linear, and according to omnipowerusa it should be linear.

From: www.omnipowerusa.com/calibrations.doc
I find 0 volts = -14.5psi, and 4.8 volts= +43.5psi. I'll use these numbers and you can let me know if they work. If you have the internal pressure sensor hooked up I can write a special program that displays both pressure sensor values so you can compare.

I needed a female to female serial null modem cable to update the unit so I hadn't gotten that far yet.

Actually there's no need to have a null-modem adapter anymore with the "Big" processor, assuming you have the serial expansion card. Just hold down the rotary encoder knob down during power up and it will update from the other serial port instead.

Yes I have the serial expansion card. Originally I was going to try hooking it up to there since the end of my Gigaware serial to usb cable is male instead of female. I will try to remember that next time an update comes out.

Update 2.24 is available at lcdboostcontroller.com

Supports 4 bar OMNI sensor.
Allows two 0-5 volt sensors to be displayed on the screen and datalogged. Currently these extra sensors are defined as Oil pressure, and AEM EGT gauge. To datalog, use 0x18 for sensor1, and 0x19 for sensor 2. These extra sensors can be used to display whatever you guys ask.
WBO2 can be displayed as AFR or Lambda. Screen brightness now has full, half, and off. Minimum duty cycle now accepts 0%, keep in mind the Macvalve boost solenoid likes to operate between 0%, 10.2% and above. Config menu items have been re-arranged grouping similar items together.

AWesome. I just got my lcdbc upgraded last night. I need to send you back my old lcdbc board. Do you want the old ittle proceessor i just pulled out too?
So when I update to the new firmware with the data serial port, I just turn the key on and hold the knob in with the update program?
Also were you able to get the lambda setting in WB02 working in this new version? And what about the little boost graph offset?
