AIM Brake pressure sensor issue
I have the 0-2000 PSI sensor installed on my MXL Pista, worked perfectly for a couple years but this year it is bottomed out at (fluctuates) 25-30PSI. In Mv it is around 1050-1060mv. I don't see anywhere that I can "reset" 0 to equal 25PSI or the mv reading to re-calibrate it. Only sensors that show in calibration are throttle, steering, and accelerometer. Could it be resistance in the wire causing the reading? I know there is no pressure, car was off, wheels turn free, and brake pedal is free..
On another note it seems I have only one accelerometer now.. not sure if it's lateral or longitudinal. I did remove the GPS module in favor of the built in on the Smartycam so my assumption is they don't need to be assigned to the SC channel IDs.

You can create a custom sensor and set the zero to your no-pressure value, then set the max by looking on-line as you apply "full" brake pressure. However, since you are the proud owner of a Smarty Cam, I'll suggest something else. I had to do this to get a progressive bar for "brake" on the video screen. What I did was look on my data for "max" pressure applied in the biggest brake zone (ie. turn 1 at the Glen). Then I changed my brake pressure "sensor type" to a zero based potentiometer. I have my max pressure as 100%. Now, the video shows a better representation of brake application

Well I can't bitch too much because i'm 99% sure it's the sensor and they don't make it. They should allow you to reset the range of values but i'll try the workaround(s) and see what happens.

hi .so i am experiencing the same problem. did you ever find a solution. when the brake is at 0 the psi is reading between 20 to 40 . it rises as it should when the brake is applied . with motec there is an easy way to re calibrate this . in the calibration table set 0 mv to 0 psi set 30 mv to 0 psi then set what ever you want after that . the sensor reads 0psi from o to 30mv so it resets the 0 . AIM seems to be different . you can set the values in the custom calibration table but then it does some sort of quadrantic equation on your numbers . its important to have a good "0" to more accurately tell when the brakes are applied . is there a way around this . thanks

You can do it once the data is imported by right clicking on the channel and putting in -x (whatever the sensor is off) in the spot for B. If you wanted to do it in the sensor setup, the only way is to do it with a custom sensor.

I run a gated channel, like Matt says. New sensor coming soon...

For guys with these sensors: Is there an off the shelf manifold to attach the sensor? I've seen a couple available that are standard thread, none that are metric. How is your's tapped into the line? Is there any bolt-on solutions or is it necessary to do a bunch of custom fittings and lines? thanks
