Amazing! Bravo! Well done! Easy piecey!
Does it go for both versions? (0.3, 0.4)

ARC PRO simple mod to switch the lap sensor into APB-mode
This simple modification switches the lap counting sensor of the ARC PRO into an APB-compatible mode.
The modification relaxes the ID-LED-to-guide-blade constraints of the ARC PRO enabling cars with surechange guides and/or cars with ID LEDs placed a long way back from the guide blade, still, to function correctly. This is achieved by switching the lap counting dual sensor into an APB-compatibility mode.
In making this modification, the analog lap counting function is lost.
The modification is straight forward... and done carefully can be reversed if necessary.
The modification is for DIGITAL use only.
The following nine photos show the procedure (no text)...

Just two points to ensure a successful result:
1/ Take care when removing the small white four pin plug... try not to tug on the wires... instead... carefully loosen from the sides of the socket.
2/ Take care not to damage the blade detect sensor parts which stand up-right from the pcb - these can be easily damaged. They are no longer used after the modification... but reversing the modification would fail if these parts become bent or damaged.
Enough from me

Can I also just cut the grey cable if I don't need backward compatibility? Seems to be easier, my Arc Pro is out of guaranty anyway
I would recommend waiting a couple of weeks before doing anything which is hard to reverse i.e. wait and see what others find regarding this mod. If you do decide to cut the grey wire... I would propose the cut is made 2-3cm back from the plug... so that a rejoining could be effected if ever desired.Can I also just cut the grey cable if I don't need backward compatibility? Seems to be easier, my Arc Pro is out of guaranty anyway
Hope this helps.

So there are three options...
1/ remove the grey wire as per above (DIGITAL MODE ONLY)
2/ butcher the sensor board and add a low profile switch (as per kind suggestion by Klitgaard and now as per photo below).
3/ wait for one of my DIY plug in boards with onboard pnp transistor which auto selects between modes. Apologies to everyone who is patiently waiting to give this option a try!

Switch position:
left= normal ARC PRO mode (digital/analog)
right= APB mode (digital only)

I will be doing this mod Doc, but it will be once the airport opens up again...not willing to risk messing something up (even by accident) and then not be able to get a replacement PB until the end of JuneAny feedback on whether this mod is liked or not, and whether it does what it says on the can, would definitely help in due course please. Ive been using the mod for about six months with no issues whatsoever. Hopefully others will enjoy a similar experience![wink.png]()
