    I need help. After replacing stock module on my XLC1200, my speedometer now displays 10-20 mph higher speed than actual. I installed a Screamin Eagle non adjustable type and had two dealers confirm the module is correct for this application. All other functions are ok. I performed the learning procedure the manual way and it completed the learn process without failure. There was a brief time on the first start up that speedo needle reacted to engine rpm's and check engine lamp coded. I errased the code and restarted and it never came on agian. I think it was a p1009 code,i didnt write it down.
    Please help me if anyone has the answer. Thanks
