this is a very small range of values to express a large range of pressures, can you pick values for range and domain arbitrarily?

I am not logging the values but this is what I am using to maintain bottle pressure.

I have it hooked up to a relay to control the on / off of the blanket. It accurate to +/-2psi. Independant testing in my lab verified their claim using a King Nutronics Precision pressure standard.

Well hooked it up, read 1259 with a actual pressure 580 or so...
2.61 Volts fairly steady...1259 PSI from the PID
The voltage was pretty steady and the PSI matched the formula.
Guessing I need to offset the voltage? How do I do that to try and match the actual pressure?

Hooked it up to the V2, the Voltage range is just too tight with the Dynotune Sending unit fluxuated badly as Blacky said it would, will revist this with a different sending unit (one that uses most of the 0-5v range) later...on to COS 5

Going with the Autometer 0-1600 sending unit from Summit...ordering tonite, hope to have it installed first week of Nov.
Bored here in Singapore...Drew a Nitrous Bottle in 3dsMax and imported it for a Pressure guage.

Very cool!

Beer, since my EXT.AD1 input is used for my LC1 can I do the same as you exept use the EXT.AD2 input for logging nitrous pressure??? then use the same common groung on the V1 as I did for the LC1???
THANKS
Yes that should work. Thats how I hooked up my V1 for WB and fuel pressure at first. Then I modified the fuel Pressure to work through the EGR Pinout in the PCM (Good Unused 5V source).

I like that dash Beer. Kinda reminds me of a process control graphic!
Cool now all I need is the custom PID for the autometer sending unit..hint hintOriginally Posted by Beer99C5
