LNF ECU with LDK 4-bar MAP Sensor

[DrJones_CMR]

First off, I tried to have proper forum etiquette and searched the forum and google to no avail. So sorry if the answer is already here!

Long story short, I have a GXP and replaced the engine with an LDK engine from ATK engines.
The intake manifold on the new engine came with the 4-bar MAP sensor (p/n 12612110) and I need to change my linear and off-set for the new sensor.
Looking at the stock Turbo Buick Regal (2013 in this case) tune I should change it to:
Linear: 424.99 kPa
Offset: -32.50

However, in my tune, HPT limits the range for the linear constant (ECM 4010) at 0 to 102 kPa.
The tune files are very different in layout and what is available to change (obviously the actual values are different).

What is my course of action to be able to enter the correct values?

Thanks!

For clarity, here is the screen that is giving me troubles.
Note the red arrow pointing at the allowable range (0-102).

there is an error in the parameter description, its not pressure per 5 volts, it should say pressure per volt (singular).
For example a stock GMPP LNF file shows 65.89 and -6.35. 65.89*5=329 kpa. subtract roughly 101 kpa for atmospheric and your left with 228 kpa which is roughly the limit of the 2.5 kpa sensor in the GMPP kits. its really rough math and sensors aren't calibrated perfectly but that should get you the idea.

you should be entering 84.99 kpa and -32.50 offset.

also 102 kpa*5=510 kpa which is roughly the same range as [ECM]4033 range limit. in case the above wasn't enough validation.

Thanks for the reply. I kind of came to the same conclusion when I did the math myself.
Using 5v and a slope of 424.99 kPa/volt means the sensor would have a huge (pointless) range.

No worries. Its an old issue not talked about much.
