Figuring out the mileage on a TJ engine

The old Willys project that I picked up a few weeks back had a 97 TJ frame and drivetrain under it. The more I look at the drivetrain the more it looks like this thing had VERY low miles on it. Last night I took out the distributor to spin the oil pump to prime the engine before trying a compression test. The distributor cap didn't have any deposits on the terminals and the distributor gear still had the factory paint on it. I believe the ECM should store the mileage in it so if I could find someone willing to let me plug it in their 97 TJ with a 2.5L shouldn't I be able to read out the exact mileage ? I have someone who is interrested in picking the motor up but wants to know the mileage and condition.
Also does anyone know what the compression should be for a 2.5 ? (one thats been sitting for a long time). This thing also has 4.10 geared axles, ax5 5 speed and a 231 in it that hopefully someone could use.
