Higher value for generic inputs
Hi
the maximum value of generic imputs 5v value is 3267kpa
I have 1600psi sensor to control my nitroz battle wich is 11031kpa.
Is it possible to make?

Re: Higher value for generic inputs
I'm sure you can use it, with resistors for a voltage divider or an op-amp to multiply; whichever is needed. I think you will also have to create a "custom" data field for it to read the units properly.
Re: Higher value for generic inputs
at a guess the megasquirt is using a 16 bit signed Integer to store the number x10 hence being limited to 3276 could you not set it to psi use it up to 1600psi and if you want to know the kpa have tuner studio or mega log viewer convert it for you

I dont need to know the kpa value, psi works as well, it just need to turn off heating blanket at 900 psi

Re: Higher value for generic inputs
Any chance to upgrade sensor input scale ? I am willing to pay to the developer
To bad that i can not control NOS pressure

Re: Higher value for generic inputs
Not going to happen on MS3 unfortunately. A larger dynamic range really requires floating point numbers which aren't practical on a processor with no floating-point module.PUMPISH wrote:Any chance to upgrade sensor input scale ? I am willing to pay to the developer

...or use bar which is kPa/100 and thus easy to convert in your head if necessary!grom_e30 wrote:at a guess the megasquirt is using a 16 bit signed Integer to store the number x10 hence being limited to 3276 could you not set it to psi use it up to 1600psi and if you want to know the kpa have tuner studio or mega log viewer convert it for you

In kpa I need range up to 11031 kpa to get the correct value

Re: Higher value for generic inputs
Actually, you could have a project switch to allow a range of +/-32767 instead of 3276.7 since this is basically only a display issue that is handled in TS and the actual internal value is meaningless to the MS3 anyway. However, that would affect all generic sensor inputs and would be tied to the project and not the MS3 which could lead to strange things if you use a different project.jsmcortina wrote:Not going to happen on MS3 unfortunately.

Having this option per sensor and tied to the MS3 might be a bit more tricky but that's still mainly a TS thing (plus one bit per sensor for the option).
