Do you mean the K-Pro was removed? IF so the ECU will not work. Once an ECU has a K-Pro installed it must always be there.

Why? what changes in ECU?

What he's saying is that when Hondata installes their daughter card, they modify the Honda ECU - in some way they may be unwilling to share. Because of that, if the Hondata board's ever removed, the ECU will not work.

If Hondata won't share, and you know how to solder, compare your ECU with a dead-stock one to see what changed. Even then it may not work, especially if Hondata changed some firmware in a chip other than the ECU program proper...
