You can wire in the digital wheel speeds as long as you have the MXL2 auxiliary harness that have provisions for all 4 speed inputs. As Matt pointed out, we will need the help of Italy for a Teves template but it can be done. Let us know if you need help.
I haven't worked with the Teves, but you would be able to correct the wheel speeds in RS2 with an adjustment to the channel by changing the A variable in the linear equation. You could make this a standard channel when you import the data as long as the circumference number isn't constantly changing.

Not as direct as what you want, but it should work if I understand the problem correctly.

Curt Jung should be able to program in the circumference directly to the Teves but will require Curt to physically be at the car or maybe a possibility of sending the unit to him. Much easier to send the circumference via CAN..

I do think the AiM MXL2/MXG/MXS will accept two different speed CAN inputs...

Keyword being "inputs". Tire circumference would be a CAN transmitted value

Thanks for the clarification. Always learning...

So the circumference would be loaded as part of a dash config and sent to the ABS control unit?

Obviously, not this make dash.

Correct Peter. The tire circumference and trim switch value is transmitted via CAN from the logger to the Teves. Only the Mk60E5 though. The Mk60 would does not need this information. The system still works, just not to its full potential.

Thank you all for the discussion. This is very helpful.

My MK60E5 works great without the communication (it was set up for the proper tire diameter), but it would be nice to get all of the pressure and wheel speed functionality.

Does the AiM MXL2 hardware have the potential to support transmit functionality and it just needs to be properly enabled (software/protocols?) by the AiM folks in Italy?

If a MXL2 can be made to work in this manner I will swap out my MXL Pista immediately, otherwise I am not sure it is worth the cost.

Cheers,

Krokodil, The boys from AIM are here in Charlotte this week at the Motorsport Expo. I am spending the day with them tomorrow at the show. I spoke with Josh from the AIM California office tonight and he said they have the MXL2/MXG/MXS Teves template ready and it just needs to be implemented into the firmware/software. The CAN transmit is in theory supposed to work but I still need clarification. Stay tuned, I will get exact release dates for you tomorrow along with pictures of the new MXS 5" color display.

Excellent. Thank you. We are not far from Josh and the AiM folks in CA and the race shop (Vision) works with them quite a bit. The customer service is always excellent.

We can work directly with them if they are interested as we have a car with a working MK60E, an existing MXL Pista, and a need for an MXL2.

Thanks again.

Joe - I'm not sure "exact release dates" and AIM go together. Don't get me wrong, I love my MXL2 but release timing is not one of their virtues.

Say hi to Dwain and Tess. I worked on his race team on the Grand-Am Cup series back in 2005/2006. Our win in Laguna Seca.

So true wparente, so true. I am still waiting on the PDM they showed me 2 years ago...

Will do. Did you stop by Dwain's shop a while back? With your wife/girlfriend? If so, I believe we met and spoke briefly.
