Hello eagleMark I'd like to thank you for posting up how to initiate the lean cruise mode on the 7747 ecu. I have had TBI on my 304 v8 scout motor for 3 years now and want to try this for more mileage. I have spent over 5 hours and have hit a road block so I need help.

-I have both a windows vista service pack 2 laptop and a Windows xp service pack 3 desktop both computers are giving me the same message in the command prompt screen (black box) I am not great with computers so this could be something easy to fix....

-They both give me this message= (Can't open output file: 60227) This is my bin file from my 7747 ecm it seems neither computers can open this file. However I can open it with Tunercat so I am lost or stuck. This is what the command looks like that I type in:
S19_Pat_.exe HIWAY747.S19 0xD000 602227 HiWay.bin

-I have accounted for all caps spaces etc. and had many mistakes. Once I got it typed in correctly with both computers they both came up with the same message so I hope that helps!!!!

Thanks,
Brandon
