I just replaced the engine in my '90 with a 383 with a new cam, heads, etc. and I chose the Ostrich 2.0 to tune it.
I'm having I think a multitude of problems, and I am nearly positive the Ostrich is one of them.
Here's the condensed version of what happened:
When I turned the key to "on," the radiator fans both came on like they do when you jump ALDL pins for diagnosis. Then when I cranked it, it turned over but wouldn't start. I messed around with the distributor and the throttle and looked for any disconnected wires and hoses, but no luck.
Eventually, I decided to eliminate one possibility by removing the Ostrich and reinstalling the original memcal. It ran this way, but very badly.
Anyway, now that I know the engine is capable of running, I want to troubleshoot the Ostrich. I can't find a manual or any documentation for it online (except a Moates guide on installing the Ostrich 1.0) so I have no idea what to do. From what I've read, the switches on the side are to select the wire count of the cable being used. I initially tried with them how they were already set (both switches moved toward the USB port), which is for a 28-pin cable (which I'm using). I tried it with every possible combination of switch positions, but didn't get any response. From what I can tell, the ECM should default to the memcal's "limp home mode" if the Ostrich doesn't work since the old memcal is piggybacked on the G1 adapter. But it doesn't. I'm thinking my issue is: incorrect installation, incorrect switch settings, and/or perhaps something wrong with the bin (but it was created by someone who does this for a living, so I doubt it).
When I crank it with the Ostrich hooked up, I do not smell any fuel. I would expect if the injectors are firing but the engine isn't starting I should smell gas coming out of the tailpipe, right?
Here is a picture of how it is hooked up:

Edit: I just pulled codes from the car, and one of them was C41, which means "Loss of ECM serial data communications." Don't know if this helps.

I uploaded the bin using tunerpro RT, then verified the Ostrich RAM against the bin which returned a success.
