    That's an option but I don't think it would work because the "ferrite man" component needs to be at that braid end of the wires and together. There is a second cap on the motor already and it doesn't help with Carrera using the Carson chip, at least I don't think it does. SSD cars need 2 capacitors, one on the wire and another on the motor.

    So unless I'm not understanding what you're saying it doesn't seem like it would make a difference.

    You could solder the cap in the lead wire from the SSD chip to the motor before the connector - that way you unplug the the SSD chip from the motor including the cap. Connect the Carson chip with the motor without the cap...

    Cheers!

    Looks like the Carson chip will be used best/most for guys who want to permanently use Scalextric DPR cars on Carrera DXXX. We set up a second CU at our event so guys could use it to code their cars and seamlessly join the field. It's the same thing we do with SSD.

    That crazy removal of the capacitor is a bit more troubling. Some cars ran just fine with the cap in place and others lit up the CU and RMS board like a Christmas tree. Greg (Mr Flip)'s car was literally sending feedback at a rate of about 10X per second until after we removed the cap. Afterwards it ran like a champ.

    So I now rate the Carson chip at about 5/10 overall. The big selling point was the ability to swap the car back and forth between the two systems with less than 30 seconds of work. If you're going to use a car that way the time it takes will be 10-30 minutes based on soldering skills. Factor that in with loss functionality, ghost car pace car and easy coding, and the price, it makes it a cool idea but by no means a must have. It's cheaper to have a DPR chip and convert the non DPR door with a Carrera chip attached to the top of it. The only downside is having to open up the car to change it and changing the plug arrangement over from the non digital DPR cover. I've done it to a couple DBR 9's and they work great.

    You can't do the double tap method to code cars when other cars are racing on the track. With Carrera OEM cars you can doe any car any where when other cars are running, but not with the Carson chip. Not sure if that's because of the Scalextric wiring or the firmware in the chip, but we always had to use the CU code button to code cars.
    That's a shame- not a show stopper, but definitely a shame. That ability is one of the best minor-but-fantastic details about Carrera digital. Although I know there are a lot of D1XX users (many here on this board) who don't even know about it.

    The fact that you should remove a cap for D1XX, and that same cap needs to be in place for SSD sort of robs the Carson chip of what I've always thought was it's most appealing attribute- easy swap between the two systems.

    Of course, I have no plans to ever run on SSD, so the Carson chip has very limited appeal for me, as I don't mind a little cutting and drilling and soldering if I chip an off brand car. But then my DPR car purchases are few and far between.

    Yes sir, the chip blows, sometimes with a little puff of smoke I blew 4+ chips because of that a couple years ago before Mr F. looked at my car to see what the problem was. Funny thing is a couple chips blew as soon as I put the car on the track, one lasted an entire race, and another went for part of a race. There were several generations of their chips out there, not sure which ones were more susceptible to blowing up quicker.

    Just curious- does removing this capacitor cause any issue if you switch the car back to SSD? I know the ferrite man should be in place, but I'm not familiar enough with Scaley to know what the result of removing this capacitor is?

    For future reference: it would have been the red wire that connects to the curved, inside rail. The two that connect to the straight outside rails are how the chip draws power. The red wire leading to the pit lane rail is the one that sends the low phase voltage signal to the pit lane.

    Your other pit entry switch really shouldn't have been any different. They all have the same jumper in them. In fact, the pit entry switch performs exactly the same old pit or new. I guess it's possible the chip firmware is different. I'm wondering if you happened to have found a hyper-sensitive Carson chip, or if you have a slightly out of whack pit entry switch.

    Solved; switched to a different pit lane, the 30346 that came without the adapter unit.

    every issue i've had with a Carson DPR chip has been corrected by running straight +/- from braids to the chip - have 20+ of them running now

    We're going to be racing all Carson DPR cars this weekend on my Carrera digital track; I want to be sure they will all work. I ran a different DPR car on a friend's Carrera digital track a few months ago and we didn't have this problem. He didn't need to do any modifications whatsoever for it to work. I'll try to figure out which wire to remove and see if that helps.

    Is it simply a matter of removing one wire? If so, how will I know which one???
