PWM, if there is RFI coming from the motor or inverter, or whatever, pretty much NOTHING is going to fix it besides a more powerful keyfob transmitter. That would have to be a custom thing, because they all pretty much use the same cheap piece of shit circuit board / xmit circuit in all of them. Now THAT is going to need a new certification from the FCC, etc etc, major pain in the ass. I don't see that happening.
Software CAN fix it, by turning that fkn nag OFF once the bike is in motion. Ok I start it, I get it in 'go' mode,now turn the GD keyfob error crap OFF until I park it again. OR... have it activate ONCE, to alert the driver, he acknowledges it and NOW it is deactivated until the bike is parked. Thinking here is OK, the sob is not talking, stop being like a wife I HEARD YOU THE FIRST TIME STOP NAGGING !!!
If it's out of range because you dropped your keys at 60 MPH, guess what, they are NOT going to undrop and FIX that situation, so WHY KEEP TELLING ME !!! Telling me again 10 miles down the road doesn't do dick, to help me reFIND THEM !! SHUT UP...
NOW...if you are nagging me and I got my keys in my pocket, then it's a nuisance alarm, STOP SHOWING IT. Turn it into a NON nuisance alarm. show it once, it gets ack then leave it alone until bike is RESTARTED.
You said to slowly walk away from the bike until the alarm comes up. That might not work. Is there a time delay on how long it has to be out of range? Let's say there is a 30 second delay. You go out of range at say 4 seconds / 5 feet from the bike but won't know until you are 50 feet from the bike. May not be very helpful info.
Why is it that some of the things that are really simple fixes, are the ones that are almost impossible to get anyone to work on?
