Hi from Washington - 1993 Isuzu ELF

Hello, I am trying to get TunerPro RT to read my 1993 Isuzu NPR/Elf with GM truck TBI. I came across this forum tracking down $85 definitions file at http://www.gearhead-efi.com/Fuel-Inj...Information-85 It is a great alternative to pick-up but messing with pre-OBDII can be tedious...cheers, Hugh Seattle, WA

Update: I successfully read data from my truck yesterday using the $85-16147060-V1 files found at:
http://www.gearhead-efi.com/Fuel-Inj...erceeded-to-D8
and the advice to have the engine running prior to connecting. This is with an old HP Pavilion laptop running Win95 for TunerPro.
