Default How do I de install my Thundermax

I am getting ready to sell my 07 Road King Classic and I want to remove the Thundermax Auto Tune and Re Install the OEM ECM. Are there any special steps to reset the OEM ECM once it is installed? If so what is the procedure. Any help is appreciated.

No, once you hook up the OEM one it should just fire right up.

Thanks. I asked this question to the tech at my Harley shop and he tried to sell me an entire reprogram for $150. I'm not a mechanic but I'm not a dummy either. That just didn't make sense.

You need to replace the WB O2 sensors w/the OEM Narrow Band ones ?

If you installed pipes and a high flow A/C along with the ThunderMax (Stage 1), expect the bike to run like crap when you go back to the stock ECM.

I plan to put the OEM pipes and air cleaner back on at the same time. Won't everything work normally?

You will be fine with that setup basically back to stock, change the wego's as suggested.
