I believe the map sensor on our SRT6's is a 250KPA sensor which translates to 2.5 BAR. That means the highest MAP pressure the sensor can read and output is 36.75 PSI (2.5x14.7=36.75 - but remember, we have to subtract atmosphere from that to get boost, so total boost it can read is only about 22 PSI).

It really looks like you have your logging software configured incorrectly, and it almost looks like it thinks the sensor is a 500KPA sensor. Is there a way to change the scale for the logged items?

I don't have the actual specs for our MAP sensor, but based on other boosted applications that I've dealt with, the sensor range is generally 0-5 volts. That voltage range is usually scaled something to the effect of 0V to ~1V is vacuum and ~1V to ~4.5V is scaled linearly for 0-22 psi of boost. So if you can log MAP Volts, you should see less than 1V when in vacuum (basically at idle and decel), about 1V when just going into boost, and if you are stock (no pulley mods), about 3.22V at wide open throttle (based on a linear scale, a range of 1-4.5V gives you a scale of 3.5V for 22PSI, or .159V for each PSI of boost - 3.5V/22PSI=.159VperPSI, so stock boost of 14PSI x .159V per psi=3.22V).

So again, I would check the setting of the MAP logging to make sure it's set for 250KPA or 2.5BAR, and if you really want to validate your MAP sensor output, log the true voltage the sensor is outputting and see if it falls in the ranges I've described above (remember - I don't have the actual sensor specs, so the values above are guestimates, but should be close enough to determine if your sensor is acting funky).

Good luck!
