Up for sale is an OC.T Stage 1 ECU and matching TCU for the tiptronic transmission. Great combo. Never had any problems. The ECU is an A box. I have pictures of both. And, of the ECU open with the chip shown. Both come as a complete ECU, not a chip. So, it's plug and play. ECU was $1340 new and has about 7,500 miles on it. The TCU was $800 new and has 7,500 miles on it also. I'm asking $900.00 for the pair. Will take reasonable offers though.
