I have a FAST system with the wide band O2 option and the harness for sale. Here are the specs:

Part # 30-111010
Serial # 03108
Dealer # 007
Batch # J
Firmware Revision: B2 Bundle
Date of Manufacture: 5/20/02

This system was built for a GM L98 with HEI but I checked with FAST and it can be converted to work with an LT1 / Opti for about $40. However, the harness may have to be changed or modified. It does have the Wide band option, the sensor is NOT included.

I'm asking $1400 shipped for the whole system. PM me or email at n20dave@hotmail.com if interested.

Thanks.
