Just get a 1227730 from a v6 and the memcal will be right. They were used in v8,and I think 4cyl applications as well, so look for the v6 source.
The 1227730 can use lots of different code. For a stock v6, $88 is prolly your best bet. I'd locate some code first, so you don't end up with a useless box.
The big advantage to me is that all the Moates stuff works with the 1227730 (Ostrich etc), so you can tune if you want to in the future. It will take a newer eeprom as well, not just the old eprom. Also, the data stream is way faster, and using tunerpro and a 2 transistor cct, or an usb-aldl cable you can make use of tunerpro's very advanced features.
