We are thinking about jumping on the group buy for the 5-Star tune and need to go to our storage facility to find the correct PCM number. If you have located yours, please advise where you found it!

Thanks.

The PCM Code on my 35K is located behind the front engine access panel. Looking at the drivers side of the coach up against the extreme right side looking aft on the firewall is the control box and the code is printed on the box. Also on my unit the OBD connector is in plain sight mounted on the left side of the steering column. I did use the group buy and be aware of one other thing. For the full effect of the tune the coach will need about 5 cycle of operation. The control unit is smart and needs a few cycles to fully optimize for your driving style.

On my B the code was under the inside dash, against the firewall, not outside as 5 star told me. It is very close to the OBD plug.

Thanks; we found the code in the engine compartment.

When you say the full effect needs about 5 "cycle of operation", do you mean driving cycle? I appreciate the info.

Yes driving cycles, Driving it a bit shutting it off and repeating that a few times. I'm not sure if it needs to be shut off and cooled down to be considered a cycle or not.
