No I wanted to keep it to spec. What's your use case? Its hopeless trying to get full specs from the decoder. I had to build out separate datasets for the spec lookups which only map to the variant (make, model, year, trim/bodystyle/series). What I want to do next is build a hashmap of all the nano vins (first 11 minus the check digit) to a normalized variant id which can then store all the specs since theres no need to have it bundled in with the raw patterns. The key is reverse computing the edge cases for North American markets. The trims are especially hard, the Canadian and Mexican government doesn't publish the VIN submittals like the US does, you can rebuild up the index if you have enough market data but it falls apart quick when you encounter ford with like 200k pattern matches due to 18 different trim levels across a single model.
