input slope and intersect

[moreause]

ok a bought a sensor for my nitrous...0.5 to 4.5V 0 to 3000 PSi

i wanted 1500 psi but they were only making 1000 and 3000 in that price range

so to be showing correctly i would need 750 and -375

but since i need the minus sign i'm left with 2 digit....is there a way to move the point??


so for now i just putted -75 and my value is alway 300 psi off (but readable)

since you are kind on the topic i need, ill post here instead of making another thread to have two posts, i have an autometer wb, which reads 10-16 afr, and the output is 0-4v, what would my slope and intercept be? thanks in advance for any help.

if i remember my calculation it would be 1.5 and 10

kinda go like 1.5 afr per volt ((16-10)/(4-0))
and offset 0=10 afr so offset =10

Did you know we have a 2000 psi nitrous sensor?

Anyway, we changed the analog input entry screen sometime last fall, you can enter 5 digits including a decimal. For this code you can enter this as either "-0375" or "-375.".

I think the older ones are formatted as xx.x, and you can't move the decimal. Yeah, it's coming back to me. When we added the nitrous we changed this for this very reason. All of our older sensors did not need this
5th digit.

I guess the only solution is to keep it as is or have it updated.

Contact service@aeroforcetech.com if you decide to get the update.

while im in here, is it normal for the tps to read 13% and 0.00v at idle, and 76% and 3.16v at WOT?

yep it is

but the voltage are not the real tps voltage don't ask me why, they don't have the offset

the real voltage at the tps is more equal to 13% to 76% of 5V

yep i saw that you add nitrous sensor...just after i had mine

and i just saw i new gages on a caliber srt-4 does the new gage foe the Nsrt-4 support all the same info ass the Csrt-4??

hum after reading on the site they seem to be different
nsrt-4 is sr serie
and
csrt-4 is cnc serie

They are quite different gauges internally, Dodge added parameters (and removed some as well) for the Caliber.
