So far I have found the bin for the express van, but the 12212156 OS XDF appears to have some bugs and major errors from reading through the thread. http://www.gearhead-efi.com/Fuel-Inj...2156-xdf/page2 This is why I started using HPTuners a few years ago, it costs money but the bugs are worked out because people pay and they have a reason to fix them. The xdf for my 95 G30 van got the job done but there were some obvious bugs that complicated the process once in a while. If there is a fairly stable 12212156 XDF I missed let me know.
