Edge cts3 question

[bigbird]

Anyone know how high of boost a cts3 will read?

I'm pretty sure it's limited by the sensor and not the scanner. If I'm not mistaken the stock sensor is a 3 bar. So about 30 or so PSI. Maybe a little higher. If you want to read beyond this you'll need a higher pressure sensor and programming to match the scale of the sensor

1 bar =14.5 psi so should be able to read about 43 psi.

Perfect, can a guy get a 7 or 8 bar?

Edge will read to the max of your stock sensor, but you can also add whatever sensor you want (0-5v) and it will read that as well. So you could get a 0-100psi sensor and it will read it as an accessory boost sensor.

Thanks, I got it figured out

As others stated, it will only natively read the sensors on the vehicle. Some generations of Duramax handle a higher PSI map sensor better than others. In my opinion, the easiest and most reliable solution is to add an external sensor and leave the OEM MAP as it is. That means you can run theoretically whatever pressure you would like as long as the signal you're feeding the Edge device is 0-5V.
