Hi all
i just got my new mr-03 with RF-901SM module and PN Racing KO Module Adapter for 3PK.
according to PN i adjusted the steering EPA to 43% and D/R to 100% before connecting the RF-901SM module turned my 3PK off.
i also made sue that the 3PK was not on HRS/PCM it was on PPM.
then plugged the adapter to my 3PK and on it plugged my RF-901SM
now once i turned the 3PK on there was a puffing noise from the RF-901SM module and i could smell that something was burnt.
on the outside there is NO visible damage to the RF-901SM module.
but it is now not working.
what should i do?
thank you.

First off I would open the module to check the board inside. You can post pictures, too, so we can have a look at it.

first thanks for the quick response.
are you sure it will not void the warranty if the is any??

Well, I do not know customer rights in your country. In Germany you pretty sure loose guarantee with this.
If you want to save your guarantee, I suggest to contact the seller / shop and ask for advice in this case.

One of my buddies had that roast on his too. We couldn't find a replacement, but Ko propo took care of it without question.

That photo is a bypass you can do that will allow you to use the module with out the pn adapter. It works great as I used it on my 3pk when I had one
