I haven't seen much on the interwebs about it. I thought I'd ask before I buy something on ebay and hack it up. I'd like to put a 4-channel setup on a project I'm working on, but it would be nice to tweak a few things and change (or determine) the correct reluctor tooth counts. I have read about the Bosch aftermarket stuff, but I'm not interested in spending $12k+ on that.
The ones I have seen were potted electronics using wirebonds and dies right on the board which means the board can't be modified or fixed, with a power circuit board on top. The power board didn't have many components on it.
Well that's no fun. Do you remember who made them?
i've opened up a GM ABS-VI unit(probably 95ish vintage), it has a Motorola processor in it, but I don't believe I identified an external PROM, so all of the code would be in the microcontroller itself.
Delphi. The C5/Cadillac stuff.Quote:

I'd like to use a more modern 4 channel setup like the C5 or C6. I did a lot of reading last night about what some BMW people are doing with a Teves/Conti unit.Quote:
