1993 lt1 tune bdzl

[lt1-xjs]

I recently acquired a Moates burn2 and aldl cable so I can data log down the road. I am new to tuning logging so I'm trying to learn the basics. I have a custom tune with the piggyback and 27fs512 chip I've run for 18 years. It was tweaked once by a local guy at the dyno. I made a copy of the chip for future reference. Everything seemed to work ok as the file was 64k. I used Tunerpro with the da3.xdf to read the file that was installed on the new chip and when opened it goes to the parameter tree. All the values are off or missing. It showed the injector flow rate at 635.03 and the timing rpm chart was all 0 etc. The moates flash and burn seemed straight forward to copy and burn a new chip. I hope I didn't mess something up. Question is why can't I read that file ? Thanks

According to the 1993 LT1 gearhead-efi link http://www.gearhead-efi.com/Fuel-Inj...mation-DA2-DA3 the chip is 32K. An offset is required to use a 32K file in a 64K chip.

Thank you Dave, that worked.
