Those diodes sound like just the ticket for the SCW-1 motor, do they install across the tabs or inline on the power wire? I'll get laps counting again eventually one way or another.

I agree with ddyke about those dang heavy magnets. Problem is if the lap counter doesn't work, the pit fuel up requirement of the digipro system won't work either. ( I don't like fueling every nine laps so I wouldn't miss it one bit.) Also dead strips and PC's counting laps can't account for 6 cars running. I suggest looking back in the digipro discussions which will lead you to posts by Demether, a guy from France. Those guys are way ahead of us on tweaking digipro....

Learning to drive without traction mags is much easier said then done on Digi-Pro. The Digi-Pro controllers are made for the Neo traction magnets and weak motors so the lightest throttle you can apply is still way to much for magnet free cars. The huge digital chip in the car puts extra weight above the axle centerline making a roll over more likely then a slide. Maybe when I get R4 corners the Digi-Pro controllers will be better suited.

I came up with a foolproof plan to count...

Is the counter in any way associated with the rest of the system? If not remove the magnets, learn to drive non-mag, and switch to a dead strip system and a computer with SRM2 software. People throw PCs and the old CRT monitors away left and right. I have 3 in my basement. My cars last longer non-mag and crashes are less violent.

I'll try shimming the ceramic traction magnets into a position they will count laps, if it doesn't leave me enough ground clearance I'll probably try some dot neo magnets above the ceramic ones to give them a boost on the passenger side (the track reed switch is in the passenger side rail of each lane)

I already switched the SCW-1 motor to the ceramic traction magnet so it would run with other cars without taking all the power. With the ceramic magnet it requires very...

Cool update! You might try shimming the ceramic magnet so it is closer to the rail. This will increase the magnetic downforce. You can experiment with different thickness shims until the reed switch is being tripped for the lap counting.

Not sure how many amps the Digi-Pro chip can handle so be careful when using the stock traction magnet and the SCW1 motor as the amp draw is most likely higher than the stock motor/traction magnet combination. The ceramic magnet shimmed lower...

I got my parts from BRS in time for weekend racing. The Ninco Racing braid works great, it lies flat and eliminates 99% of the surging over the lane changers and pits. The ceramic magnets don't count laps in the stock position, I haven't got this worked out yet. The 9 tooth pinions were larger diameter then the regular digi-pro pinions, a little clearancing of the gear saver had it rolling smoothly in 5 minutes. The extra speed of the 9 tooth pinion with the reduced downforce of...

I did some looking and there aren't a lot of tire/wheel options taller then DTM/Porshe cars come with
I need to do something soon, my braids are clean, the track is clean, the cars are clean and oiled, everything runs smooth without surging

I just ordered 100cm of ninco super comp braid, ceramic magnets, and 9 tooth pinions. Hopefully the traditional Artin downforce/gear setup counts laps right off the bat. If I have to lower the cars to get the ceramic magnets to count...

Make sure the axles are clear of hair and lint. They have a tendancy to pick up all sorts of trash that will slow your car for sure.

The digipro cars are slower than than the analog cars due to those dang heavy magnets. I'd throw'em out the window except for the fact that they are required to trigger the reed switch under the track that counts laps. There is a mod mentioned an earlier thread about how to modify this magnet problem and still count laps but I can't personally vouch for its effectiveness. I was going to suggest cleaning the rails, but you said that you have done that with 409. I would question if...

I shaved them just past the tread grooves pretty much instantly.
According to my dial indicator I removed 25 to 30 thousandths from total tire height.

We didn't notice them slow down. We Each ran the same car every time and when somebodies car broke they would get out a new car and we'd all say "oh that's a hot one". And as the laps turned every new car seemed even "hotter" then the last.

The track is kept super clean with 409 before...

When did you shave your tires, and how much did you shave off?
I have seen cars, where the smaller tires, brought the magnet so close to the track that the car would not move!
If the trouble started after you shaved the tires, then you know what the trouble is.
Also make sure your braids are clean, as this is one of the moat common problems with the Digital cars!

After a few thousand hard laps on my ~45 foot oval my Digi-Pro cars are noticeably slower then they started life. I have never even seen a 1/32 car that didn't come in a Digi-Pro box, so I have no idea if this is normal, or caused by to much magnet downforce. I did shave the tread off the rear tires.

Is to much downforce killing my motors?
How long do Artin motors usually run before dropping power?
Will the ceramic magnets from other Artin cars fit the same spot as...
