I found a way around the firewall! I've uploaded akfm2174.bin and akfm2174.txt to incoming. If anyone has a .ecu file that works with this bin please upload it! I'm currently using the 89vette.ecu file which works for the most part (ie spark tables). >>>88 5.0TPI - F-body A/Trans(M39) Fed, 2.73(GU2) 16082173 2174AKFM /Ernst denBroeder
