GA pilot reported the EFB information for the 48TX airport does not show the correct information for the parachute jump zone. The Instructor stated a precautionary landing was necessary due to an engine problem and 48TX selected. After landing the NFP realized the jump zone information on the EFB conflicts with the sectional chart.

Narrative

While simulating an engine malfunction; the engine did not perform as it should have causing both pilots to focus on safety of flight and get the engine running properly. During that time; I verified our location on my EFB (electronic flight bag) charting application. There were numerous small airports in the vicinity; one with a parachute drop zone. I instinctively 'long pressed' on the airport icon to bring up the pop up window isolating that airport 48TX information. I verified that we were on the published frequency 122.9 (EFB freq). We were listening for traffic while in the area and heard no voice communication from anyone close. After we sorted the issue out we made a 180 turn to head back in the proper direction. It was at this time that a jump airplane contacted us on 122.9 to say that they had jumpers in the air. We couldn't initially see the jumpers as they were slightly above us; in a blind spot. No evasive maneuvers were required as all were well clear. After further investigation; the charting application does not have the proper information listed for the drop zone; it conflicts with the sectional chart. I will be notifying the application company to make them aware of their error. In the future; avoidance is best.
