I need a spare 0-5 volt input for logging a signal.

I am already using adc0f for altmaps, and the rear o2 for my wideband.

Is there any other free pin, and which mut request should i use?

 

Btw, I need it for this:

map sensor?

 

Which ROM ID you have?

I've 8840617 and so no MAP sensor installed. Is the input usable for other things, like AFR Wideband ?

Thanks

forgot to mention. i'm using 88840017, and i have a map sensor installed. i am already using that pin. :/

 

You could use the EGR temp input I would think.

 

Which pin is it?

and how do you log from this free input?

thanks

you wire you map sensor to:
-pin 92 for input
-pin 42 for +5v reference

and you alter the Boost (MDP) or JDM MAP function in evoscan to suit your map sensor's psi/volt function.

 

if my car doesn't have ics, can i use the auto/manual inputs to log 0-5volts inputs?

 

Not sure if this helps, but you can reference MR Fred's MAT logging thread if you don't have a MAT sensor and use the fuel temp sensor as an input (I think).

 

frosty: i don't hat mat installed yet, i guess i will try this unless i find any other alternative.

i'd rather keep the mat pin free in case i ever decide to use speed density.

 

is it then already mapped in the MUT, or did you change something?
Did you use the JDM sensor, or an aftermarket one?

I use front 02 sensor input for my Meth flow logging.

Since you have the rear 02 sensor connected to your wideband (like me) just use mr freds code to run your in closed loop off the wideband rather than the front 02 sensor.

Then you can connect the Aquamist flow sensor output to the front 02 sensor input. It works perfectly.

 

Find my USDM Evo 9 pinout thread. Look for the fuel tank pressure input. Its a 0-5V ADC input and should be unused on an EDM Evo 9. You can verify by looking at the wires going into your ECU.

 

and when it's connected, how do I read it in Evoscan?

thanks mrfred
