Can a 10x increase in FOB range be this easy?
#16
I followed up with ECU Docs yesterday to see if there was anything else they might have done to explain the 12x improvement in FOB range I’m getting. They confirmed what the repair report said, that all they did was change the 2 caps, adding “everyone should do this”. (They didn't respond to a follow-up question as to whether they would guarantee a range increase to anyone who had the mod done).

Can't wait to hear how you make out. Definitely do a "before-and-after" calibration, maybe with just a board cleaning and then after the caps are swapped.

I'm at 5' or less too. Quite interested in this mod.

So the mod is to the receiver in the car, not the key fobs. This makes more sense. The caps are essential to providing a clean supply to the radio receiver in a very noisy environment. Add in clock noise from the nearby processor and the noise/interferer level at the radio receiver goes up, reducing range. Fresh electrolytics with low esr will provide a much more stable supply to the receiver.

So my next question is where is the remote fob radio receiver unit? Is it underneath the seat with the MOTRONIC Controller?

10' on a good day. Seems to work better with a 1 second depress than a press and release like the newer remotes but still only 10 feet.

If one is not in a hurry the capacitors can be had on eBay free shipping ten each for $3 or so.
