Please help

K I have a 91 eclipse and the check engine light has came on.. I dont know why it is on tho, the car doesnt show that anything is wrong with it. The only thing I can figure is that I just recently put a turbo timer on it about 2 or 3 days prior to the light coming on. But I dont think that a turbo timer would throw the light tho?? This is really getting annoying and I cant find what it is coming from. If anyone has any suggestions of what I should check or anything that would be awesome! Thank you for your help.

Most likely an 02 signal outside of its prefured range.
