The rebuilder is Auto and Truck Electronics, Rogersville, TN, www.autoecu.com
They rebuild lots of electronic components, but BMW ABS units aren't their specialty. Parts take time to get and they could have your unit for a month or more. This was my second attempt at rebuild and I guess the one I had was beyond repair. They sent me a replacement, but it isn't for an LT. The unit appears to function, but the front brake lever is still soft, even after riding 15-20 miles. Last time, riding caused it to firm up. Then, there is the problem with the rear wheel locking on hard stops from 20 miles per hour. Not only does the wheel lock, but releasing the pedal does not cause it to roll freely. The unit I have installed, does not cause ABS to activate.
I made a call Sat. evening to A&S BMW in CA to ask about this ABS unit. Since they're on Pacific Time they're open late on the east coast. The tech, Tim, called me back Sunday afternoon. He told me all ABSII LTs have small, large, large, small fittings and since the one I have wasn't configured that way, it wasn't for an LT and wouldn't work. By this time, I had already installed the unit and decided to try it anyway. It doesn't work, as Tim had said.
I will call Auto & Truck Electronics tomorrow morning. The customer service dept. has been good to work with. I know they'll make it right.
