Don't know if you guys would be interested, but I'm selling off some of my GM ECM stuff I no longer need.
Moates Ostrich 2.0. Bought it in Feb 2012 and only used it in my C10, still looks new and functions as such. Includes USB cable, and ribbon cable with TPI Memcal still attached. Can be used in a TBI ECM as well. Or whatever else you want it for. Very nice little tool, with this I could update maps while the engine is running, off, whatever. Super easy to use and it links directly with TunerPro RT.

1227730 TPI ECM - I have 2. One is an OEM and the other is a Napa Re-man. Both tested good. This is the 90-92 Speed density ECM.
1227165 ECM, 86-89 MAF ECM. With Complete clean unhacked harness from a 1988 Camaro. No MAF.
