The firebird has a yanmar diesel from a john deere tractor. The model is 4TN82, meaning 4 cylinder 82mm bore. Comes out to 1.8L. 33HP stock, I've got a turbo on it and I think it's somewhere around 100 now. I've got an NV1500 5 speed behind it and it's not particularly fast but the diesel instant throttle response and turbo make it sound and feel fast haha. mileage is the name of the game.

I looked at like 4 XDFs last night with no luck. I'm going to look through some bins and see what the heck is the deal with these bogus numbers. Every XDF I found has the address down as 0xB2B. I assume this is the starting address and the only thing that signifies the length is how much stuff is in the table. When I look for 0xB2B in the disassembly pages that some of the old school guys have made there's nothing listed as far as I can tell, however it seems like there are other unrelated bytes pretty soon after that address where I don't think an entire table would fit in there. I wonder if it's possible that some bins or ecus or something only have one AFR byte for the whole function rather than a table, but why would all the XDFs have a table for the 1227747. I'm super confused. My brother does some intense assembly programming on hacking the old nintendo 64 game console, I'll try to see if I can get him to look at it with me. It's hard to get him to look at anything other than the nintendo 64 but I think he would get excited about enabling a feature that the EPA blocked. He has an 89 camaro with the 2.8L and gets close to 30mpg stock.
