I never did read any real details on how you implemented ABS. Is it a straight vette setup ? Did you have to "reprogram" it ? if so, how did you interface it ? What is the path for more people adopting ABS into these cars ?

The rack was a remanufactured part that had a defect in it. It looked liked it had been clamped in a vise at some point due to the marks on it. It developed a 2 inch long crack right in the middle of the vise marks. I installed a new rack that looks like it was deburred and have had no issues.
The ABS unit is a 2006 Corvette Z06 unit. I used the Z06 unit because it has the right calibration to match the Brembo calipers I'm runninG. Same piston volume as the PBR calibers.
The hardest things I had to were:
Getting passive rear wheel speed sensors in the Ford 9" with the correct number of teeth to get the pulses per rev correct. I ended up using 2004 Mustang wheel speed sensor and 2006 Mustang tone rings. I have a ton of time in making the backing plates to get the wheel speed sensor, park brake and the caliper to all fit up robustly. The front wheel speed sensors are production C-6 Corvette on the DSE front clip.
Building all the brake hardlines. I have about 40 feet of S/S brake line in my car. I purchased a hydraulic flaring tool to get all the flares right. For the inverted flares and the metric flares.
Building the wiring harness so it is not susceptible to EMF or noise. Routing it in the car to keep it away from heat and is durable.
Of the things that I did on the car ABS brakes was the hardest because it was the first time I tried it. I still have a prop valve in the system so if it faults out I will not have too much rear bias.
I got the system to work by tricking it to think it was installed in 2006 Corvette. Due to the fact I have a stock C-6 ECM in the car I hooked the CAN data stream up between the two. The other sensors were faked or installed.
