Hey guys. After updating all my software, firmware and bootblock I am totally unable to read/flash. I keep getting bootloader rejected errors. I thought it was just the 01 LB7 I was attempting to tune. But after dealing with it for an hour I decided to try and read my LBZ and its the same scenario. I really need to get this thing figured out as I have 3 Dmax's to tune and 2 Cummins. Any help would be greatly appreciated.
Update.............I was able to read and flash the Cummins. Still no go on my LBZ. Tried 7.5 with no luck, and V8 came up with an error saying that DSP5 operating systems arent supported??
Ok another update. I flashed my LBZ. I guess I wasnt aware that we cant read DSP operating systems anymore. I used to be able to I thought. So, basically it narrows it down to the other customer needs an ECM I suppose. We pulled fuses and battery cables till our faces were blue with no luck.
It's never been possible to read a DSP tune out of an LBZ or LMM, the restrictions Bosch put in the ECM means we can write to certain 'spare' parts of the memory but we can't read them back out. So if we allowed reading of DSP tunes you would only get 'some' of what is needed.
Ok, makes since. It has always been an LLY or an LB7 that I have read with DSP O.S. Thanks so much for the reply!
