Working slowly through the ABS parts, the thought of building a stand-alone test rig to power up the ABS pump and test a working system on the bench crossed my mind ….. that and tinkering with code again to see if I could have a swift chat with the ECU bit. Quite a few of the bits have been cleaned and modelled and that also gave me a chance to try and work out the specific differences between the ABS part numbers (caliper/master cylinder) and the standard bike ones. What little I found is added to the ‘Rear brake’ page.
So now a rig is slowly coming off the drawing board with a trusty Arduino being used to power two motors for the phonic wheels …. the idea being that if I can get the wheels to speed, then apply a brake, the brake light switch will tell the Arduino the brake has been applied which will then make the Arduino retard the speed of that particular phonic wheel by 20% or so – that SHOULD (if everything works!) cause the ABS unit to trigger and begin pulsing the brake ….. that’s the theory anyway!
All I need now is a front ABS sensor and one more brake line to complete the rig and I think I can power this puppy up and see what happens …. flames, fountains of brake fluid or a big fat nothing at all! Hmmmmm.
