CLG Performance

Had to Jtag into this Ferarri TMS320F DSP Chip and clone it a while back. This one failed but luckly the customer had another that had good data on it that I was able to clone over after replacing the DSP chip. Took a good bit of time to figure out what was going on. after bad data was getting spit out on the CAN bus and checking all the logics with a curve tracer and logic analyzer I was able to determine the flash was corrupt. I also found complete sections of memory that were gone completely with no access. I got the new IC in and flashed it with a copy of the good working units flash using Jtag on the connector on the left. No documentation on this so I had to figure out what each pin does with a test signal input and logic analyzer on each pin watching activity. Then go through roughly 850 Pages on the datasheet looking for timing, commands the input looks for and a ton of other things. But I got it figured out, my documentation saved and the flash memory saved. It was an expensive reverse engineering project because these boards dont seem to exist anymore

Looking for a 1981 VW Vanagon California Emissions ECU for parts. Figure Id post up what im hunting for. Its this riser board with part numbers 273 002 stamped on it as well as 041BS stamped on it. This is the part for the O2 sensor sensing circuit inside the ecu. It converts the signal from the 02 sensor to correct fueling. These are ceramic boards with calibrated silver traces and laser welded silver microwave after inspection its not something repairable.

Probably not gonna find this AFC ECU. May end up later running these engines on aftermarket ecus
