ZR1 MAP tuning issue

I installed the ZR1 MAP sensor when I installed the Whipple and went to get it tuned today, I passed on the info for the changes to the tune, Linear: 312.50 and Offset: -11.25.
Once he adds that to the tune, the car will not start. He is using EFI Live and it shows 36 kPa on the scan, if he removes that change to linear and offset, it is at 11 kPa and it starts fine.

With the amount of cars with this I'm not finding a similar issue, anybody have an idea what we are doing wrong?

That should be the correct calibration data, HOWEVER, the best way to know if your calibration is correct is to just key on and turn on scanner. You should read atmosphere with the key on, engine off. If you do not, scaling is off.

You are sure that its a ZR map correct?

Is the Sensor Red?

If not it is not a ZR-1 Map sensor.

Red sensor P/N 12592525. I'll let him know to check scaling if he hasn't figured it already.

Thanks guys!

Spent some time playing around with HP Tuners demo. Now I see there is a spot to change the MAP offset and linear in both the MAP and SCIAP. Not sure if EFI has both, I assume so, so I'm curious if he made the change to the correct one.
