Hello everyone,
I can't seem to flash to a new tune due to code $0537. Any ideas?
Backgound:
Truck: 2002 GMC 2500HD w/ LB7 & Allison 1000
I first flashed the truck in late 2011 with a DSP5 tune. I flashed the .tun file using v7.5 and it ran well except my A/C wouldn't turn on. Since I rarely drove the truck and didn't use A/C over the winter, I didn't notice until the summer of 2012.
In late 2012, I contacted my tuner and he informed me my particular ECU's OS version didn't play well with EFI Live, so I could a) get a single tune or b) have the dealer update my ECU's OS and he'd create a new DSP5 tune with the new OS.
I opted for option b) and my tuner sent me a new DSP5 tune based on the new OS. It worked well and I've been using the tune since.
And now, mid 2014, I had my tuner create a new DSP5 tune for my newest mods. He sent me the newer v8 file and when I attempted to flash, I received the code $0537 error.
