Logging wheel speeds
#16
Bit of a shame i missed this thread as i could have helped you with all of this haha.
I removed my ABS computer and re routed the wires directly into the ACD ecu. The biggest headache was getting the ABS > ACD health check wire correct. The ABS ECU sends out a small voltage signal to the ACD ECU constantly to remind it its working. Without this input the ACD ECU Faults. Fun times.
Can also confirm the wires go into the ABS ecu on certain pins and then come out the ABS ECU on different pins which then continue on to the ACD ECU. As for the comms side i believe it uses MUT to communicate.
Do u guys really find that much time playing around with ACD computers? ive just stuck with my ralliart ACD ECU for ages. I do have my stock one i could reflash just never looked into it

I wish there was a better way to monitor steering angle. That would be the last thing I want out of the ACD ECU for driver analysis.

It helps in the corner exits and helps rotation on entry. However, I've never done a back to back comparison. I'm mostly wanting to log wheel speeds to a better understanding diff performance. I just installed a Cusco front diff (1 way) and I'll use it to monitor wheel speeds on corners.

Its also nice to be able to overlay engine parameters to see what could be causing handling characteristics of the car. motec you can also do stuff like active ride height sensors, suspension travel sensors, tyre temp and pressure live telemetry etc. list goes on n on.
AiM solo is great for a quick reference and predictive lap time etc but limited somewhat in what knowledge you can gain in lap time itself from telemetry. and no engine data logging also.
