code problem

I have an 89 honda civic hatch 5spd. I did a zc swap with a pm7 ecu out of a 5 spd ... MY problem is that when i put into reverse the check engine light comes on.... I looked at the ecu to see what code it was flashing but get a kick out of this... It flashes 11 times but yet I can find nowhere that there is even a number eleven code... it goes from 10 to 12 flash codes so can any one tell me why it does this... the car runs fine but once I go to back up the check engine light comes on and it runs like crap... I disconect the reverse switch and its stops. it runs fine again, but the ecu still flashes 11 times. some one help...
