I greatly prefer the Magic Studios ARC Pro app for running my Scalextric ARC Pro track. All my cars with all 3 versions of the Scalextric digital chips work great. My issue is with Slot it and NSR cars I have added the Slot it SISP15B SSD digital card to. These cars will run but the app does not clock laps or lap times for any of these cars running the Slot it SSD cards. I use an Amazon Fire HD 8, (7th generation) as my computer for my track.

I am following the same set up procedure for all cars. I'd like to run some of these Slot it and NSR cars against the Scalextric cars. Any help to get the Slot it SSD cars to have there laps and times register in the Magic App would be appreciated.

Hi Gravityguy... I suspect the problem here is that your IR LEDs are too far back behind the guide blade.

Either:

1/ move the chip forward if possible
2/ use the slot.it external IR LED kit
3/ do the grey wire mod to the powerbase to switch the lap sensor into APB-mode (this is a digital only solution)

Hope this helps... there is plenty of info on this forum covering all three solutions,

Enjoy.

Gravityguy... would you mind please showing a photo of the underside of the cars please?

If its not the distance between IR LED and trailing edge of guide blade that is the issue ... the other possibility is that the guide blade is made of IR transmissive plastic (certainly the caae for white NSR guide blades). In this case you would need to replace with black guide blades or do the grey wire mod as above.

I have heard this about slot cars fitted with white or grey guides failing to register laps, but I have a few cars which run NSR and MB Slot guides, which are white and Thunderslot guides which are grey, without any issues at all. By the way I run on Scaley digital and use both Scaley and Slot.it 15B chips.

Hi Longdog - many thanks for raising that point. So to clarify all of what I mention above applies only to the ARC PRO (as used by the OP) and possibly the APB if running old firmware e.g. v 0.85 or earlier.

My ARC PRO wouldn't register laps (using the Magic app) on any car unless the guide was black...that was until I did the 'cut the grey wire' mod...as for the OP's original post I suspect it's as Doc C says and the IR is too far back. I run a lot of cars with the 15B chip with no issue on the ARC PRO...I did have an issue with one Scaley car (Chevy Monte Carlo) where the DPR hatch was too far back and no laps were registered. This was before I cut the grey wire so fitted a 7005 single seater chip instead...all works fine now.

It's strange. Since it's all about IR, the color of the guide isn't as important as how well is transmits IR. For some reason, the white NSR guides have been much less IR transparent as the red or blue guides from various manufacturers. Black guides are pretty much always IR opaque. When my club races at my house, since the analog timing is based on guide sensing, we require black(ened) guides. If the guide is not already black, some black sharpie will usually get them through the night. If that's not enough, or they tire of coloring the guide every few heats due to wear, they wrap a small length of electrical tape around the guide, folded around the front of the blade so that joins don't pull it off.

Merry Christmas to all and thanks for the reply's. I measured the distance on the DPR chip sensor eye from the guide tail on one of my Scalextric cars and found a Slot it car where I was able to position the eye the same 16.1mm back from the tail of the guide. That Slot it car does register laps and times in Magic. Now it just looks like some time with the soldering iron, glue gun and drill and I'll have my Slot it and NSR cars running in Magic. Thanks again and best wishes for the New Year

Hi gravityguy...

In case of interest there is some more info on how the ARC PRO sensors work at the following link:

https://www.slotforum.com/forums/index.php?showtopic=187947&p=2226501

This leads to advisory info on positioning the IR LEDs for maximum speed performance on higher IDs.

Kindest wishes,
