Good day! I am a new member here and a new Ram owner. I purchased a K&N FIPK for my truck, but I can't get the ECM to reset. The only way I can tell that is not reset is that my radio presets are still set. Is that correct? I disconnected my battery of over 7 hours, and my radio is still set.
Anyway, this isn't the first K&N I have installed, but it is the first that has hurt the performance of my truck. Hopefully, if the ECM will fully reset, maybe the performance will improve.

Help Please!

BTW, cool website!

My friend, if you had the battery cable disconnected for less than 10% of the seven hours, your ECM would have been reset. I had a factory radio pulled for three days, put it back in, and the presets were still in tact. So that is not a good benchmark.

 

Thank you.

 

If you mean the PCM, not ECM, disonnecting the battery will not reset all of it.

You need to leave the battery connected, connect the driver side seat belt, remove the pcm fuse in the fuse box, turn the key to start and hold it there till you hear a chime. If you hold it a little longer you will hear a second chime. The first chime is the PCM reset signal, the 2nd is the TCM reset signal.

Then it will be reset.

Replace the fuse and you are done.

 

I tried this but got no better performance. I believe the K&N simply isn't a good intake for this truck. I have lost acceleration and power, so I think I will go back to the factory intake...
