'06 Mazda MX-5 Miata CAN mapping

Post by dukhunter20 »

I am attempting to get steering and brake pressure working on my racecapture/pro and am running into bit of an issue. I found steering angle to be at 0x081(129) - Offset(2) 4 bits long and brake pressure at 0x085(133) - Offset(1) 2bits long.

I have the formula set to give a raw value and am unsure what formula to give it to make it a usable figure. Any help would be appreciated.

Steering angle starts at 0, when full lock counter clock the value goes to 490, when moving counter clockwise the value goes starts from 65534 and then goes down to 65080 at full lock

Brake pressure starts at 26368 when fully depressed goes up to 63104


The series 1 RX8 mapping works for my model MX-5 except the brake and fuel FYI.

Hi,

You might want to try the raw value, but set the data type to signed instead of unsigned. You could also try "sign magnitude" for mapping as well.

Hope that helps, let us know what you find out through your testing
