Note: This adapter is now available with socket-style options. The default is machine-pi

I like what I am seeing, I haven't used it yet, the car is in the body shop, getting it's original paint restored. I think this is going to work great with the upgrades I have for the engine.

Great solver for code 51 MEM-CAL error in 1988 Camaro 305
The original eprom was suspected to be faulty, but I was able to copy the memory content using the HDR1 Memcal Header. Then I stored the original data in a new eprom and mounted that using the G1 connector. Now the car is running great again, no check engine light and no fault codes! This has for a long time been an intermittent fault that was really tricky to fault trace. It is now hard to get hold of replacement ECUs, so I tried a new approach here. Thanks to the tools that Moates have made available, it was easy to test this problem solution.
