MS3X not reading correctly the MAP value
Hi guys
I need some advice, Im located in Guadalajara Mexico so the elevation here is 5,108 feet (1550Mts) and I think the MAP should be reading around 88 or 89 kpa right?... but I am getting 101kpa when the car is off switch on.... is this the correct reading? I dont think so, I have changed the values in TunerStudio using all the type of MAPs and in any selection I can get 88 kpa.
I have used the internal MAP of 2.5bar and also I have used the external input of the MS3X to connect the GM 3bar MAP and I am getting the same value, I have checked in some other posts that its maybe the initial configuration of the project file.
Im pretty sure its configuration, should I post the complete project file here or just the MSQ file which is already attached.
Car is a GEN3 LS 5.3 in Wasted Spark.
Thanks!

Re: MS3X not reading correctly the MAP value
If you use the Internal MS MAP Sensor, change the General Settings to : Voltage Input Port = Mainboard
Then Re-calibrate the MAP and choose MPX4250 as your sensor type . Don't forget to Unlock Calibrations before changing. Otherwise your changes won't Stick. Then Lock Calibrations and Burn.

Re: MS3X not reading correctly the MAP value
Is the MAP "stuck" at 101kPa, or does it respond to blowing/sucking on the sensor port? Posting an MSL log may help.
Re: MS3X not reading correctly the MAP value
no, it does actually move on engine vacuum, it only shows around 100kpa on power on where I think it should show 88kpa.billr wrote:Is the MAP "stuck" at 101kPa, or does it respond to blowing/sucking on the sensor port? Posting an MSL log may help.
So here is a LOG file, car has another problems, but I want to first make the MAP to read correctly.
thanks

Re: MS3X not reading correctly the MAP value
This is a really simple solution. You are wrong in your thinking that Guadalajara is 88 KPA. 5,108 feet is nothing. Current KPA at Guadalajara at the moment I post this is 100.5 KPA.
So, nothing wrong with your MAP sensor:

What? No, atmospheric pressure is about 24.90" Hg at 5000' elevation; that is 84.3 kPa

Re: MS3X not reading correctly the MAP value
What you see on the weather channel is the relative barometric pressure. That's not the real absolute pressure but the pressure corrected for altitude so that people can use the same reference regardless of their location.BlackBird_SR71 wrote:This is a really simple solution.

Re: MS3X not reading correctly the MAP value
Ahhh... I did not know that. Thank you for the correction. I learn something every day. So would 88 KPA be an normal actual pressure at 5,100 feet? Trying to find the ISA standards...racingmini_mtl wrote:What you see on the weather channel is the relative barometric pressure.

Re: MS3X not reading correctly the MAP value
Found a handy site with ISA standards for Atmospheric pressures at various elevations, and depths.
http://www.engineeringtoolbox.com/air-a ... d_462.html
Now, if I could just find the coding to " Strikeout" my incorrect answers on the site that would be wonderful. Have already tried all of the standard [HTML] code

Re: MS3X not reading correctly the MAP value
Can't you just edit your older post?
I have used that "Engineering Toolbox" many times, but have to point out that the table linked to has some weirdness. It is generally correct, but is showing some place in Norway (Sognefjorden) as being 4500 feet below msl. Unless they name the bottom of their oil/gas wells, it ain't right. I believe that Dead Sea area is lowest (dry land) on Earth.

UPDATE:
Issue got resolved after we resolved the issue of the incorrect Voltage value in the MS ECU: http://www.msextra.com/forums/viewtopic ... 31&t=66453
Now it reads the correct value of 89KPA! Thank you all
