Hey all, I've been having this weird issue after changing my MAP sensor to an Omni 3 Bar and have spent hours digging for a solution and haven't been able to fix it so I was wondering if anyone else had some ideas for me.

I bought a used Vortech kit and I have plans to install it soon using the OFT tune since I have an OFT. I decided to install the MAP sensor first just to make sure it was good and take the install little steps at a time. I currently run the OFT stage 1, and after installing the sensor I flashed an updated ROM with the new sensor scalings and limits. Everything seems to work fine, no driving or starting issues, but after about 15-20 miles of driving it will throw CEL P0068.

From NASIOC and calculating myself using the Omni calibration data in kPa, I got 9.119 psia/V and +0.164 offset. I set my scaling limits to 0 - 4.75v (0.164 - 43.5 psia). To those of you running the Omni 3 bar, what sensor scalings do you use and did you have similar issues?
