Does anyone know of cases that that thing was made?

thankss

A few things from my experience: 

- I don't have the GPS:NO CONN, have never seen that error

- I have never been able to have my wheel keep time correctly, I ignore it

- My AIM was supposed to be unlocked but I too can't make changes to some components. Specifically the custom CAN stream that Radical uses to share information from the PDM to the wheel

- I have never been able to get my TPMS to display on my wheel. I did end up frying my PDM and had to send it to AIM for repair. I ended up using a loaner and when it was installed I did see tire pressures which was interesting. Once I reverted back to my repaired PDM... the pressures stopped working again. I am going to dig into that this winter. The TPMS always works on my PDM through live view and stored data.

It has no reference on it. Anyone knows where i can buy one?

I changed the PDM channel to KPH as Ben Jacobs suggested and will try that to see if it resolve it.  I think it is double converting the wheel speed signal.  

 

The second issue is that the lap timer will show the entire session as one full lap instead of breaking it up after passing the start/finish location.  I verified good GPS signal and the track is loaded in the SmartyCam.  I called Radical in the UK and they suggested having the track loaded in all the modules (PDM, SmartyCam, and SW4) they told me that the steering wheel has some to do with recording and deciphering lap data.  I will try that and retest next month to see if it took care of both issues.  I'm confident in the speedometer issue being fixed.  The laptimer I have less confidence.

I'm a little surprised they only use grade 5 hardware for that given the G forces these cars see.

 

I will mark with torque seal and monitor after the next couple outings.  Thanks!

Came across this 5x6 setup with torsion axles https://makemytrailer.com/torsion-axles-on-5x6-enclosed-trailer and was wondering if torsion actually makes a big difference in smooth towing on the highway compared to leaf springs.

Anyone running a 5x6 or similar size for track days? How does it pull?

Not sure of the torque specs, but definitely agree that the factory spec is too tight for these suspension joint with steel bushes inside of bronze sintered or polyurthane 'bushings'.  

What I have ended up doing, and have had confirmed is the same as a few others are also doing, is just 'snugging' them up until there is a little bit of resistance to them turning (when torque applied to the bolt head).

This makes sense as they have a steel tube inside the pivot joint and all that you are really doing is making sure that the side plates of the rocker arms or chassis tabs are tight enough to be pulled in against the steel tube (no end gaps).  This does mean you are relying a bit more than normal on the nyloc nut functioning to prevent them vibrating loose... but I've never had an issue.  I also replace the nyloc nuts on these joints annually just to be sure they are in good condition...

Having them too tight on the other hand will have an effect on your suspension efficiency.  You don't want too much 'stiction' when asking the suspension to work.

I have the programming cable and have been able to edit the display pages, however there are a few things in the ECU Stream that Radical has locked, even with the device key, they remain locked.

I'm also trying to understand the TPMS they used in these cars. I've been able to validate the box is transmitting to the CAN but I can't seem to get the data to read on the wheel. I can display it, but it never reads anything more than 1psi for all 4 wheels.  If I go into live view with the PDM32 I can see the data, right/wrong, but I can't seem to get that same info to the wheel.

I've seen other discussions on how their early XX's are configured and mine is: GPS to SmartyCam, Smartycam to EXP/CAN port and into the PDM.

Any feedback is appreciated, 

Kevin
