The previous owner put an aftermarket eprom in. I feel it was running way to rich so wanted to try the stock chip. I replaced chip and turned the trim pots to 12 oclock and now it won't start. The diagnostics mode reads -1. does anyone have any suggestions?

thanks
 
Thanks for the suggestions. I did align the notches properly. The fuel pump doesn't turn on when I turn on the ignition. I am missing a step somewhere??

Yeah, you've not flicked the killswitch ;)

BAsically are you getting anything ?

Obviously without fuel pump it won't 'run' however it should sound like it tries to start.

Have you put the other ECU/Chip back ?
Does it work ?
 
I replaced the race chip and the bike runs great. With the non working chip the bike turns over but it doesnt fire. Here is a pic of the nonworking chip. Can anyone verify that it is original factory equipment? Thanks again for the advice.
