Need help reading tune from 27SF512

[Rob 689]

Apologies, I didn't know you had a 7427. That is in fact a 27C512 holding 64 KB of program data, non-stacked. I don't use the BURN2 to read/write chips, I use the TL866, but I have to assume they are similar in operation. So were I in your shoes, I would merely make sure that I had the correct model number for the chip set in the BURN2 software (it does come with software of its own, right?). On the TL866, reading and writing is done simply by telling the software what model number the chip in question is, and it does the rest.


Use your ALDL cable of choice to connect your computer to the vehicle's ALDL port. In Flashhack's main menu, select "ALDL Universal Read" and then click Run. By default, Flashhack is configured to address an ECM at ALDL address F4 (which should be correct for you) with a program size of 64KB (which is correct for you). It's also programmed to automatically detect your ALDL cable. So all you should have to do is click "Read Calibration" and that's it. Once the read finishes, click "Save Bin" to save the file.

Okay so i downloaded flash hack and it seems like a useful tool i like it. Ill do the bin read and then ill just compare that to my last read of the chip with the burn 2 and then use the compare feature within tunerpro RT to see if my method of reading the chip is successful and then ill also have an alternative way to read bins anyways.

now i have more questions lol what is flash hack?

Flashhack is an awesome tool originally designed to flash $EE computers (1994-1995), but has expanded to support lots of other functions, including being able to dump any computer that supports memory read commands (such as your 7427).

You have to intentionally do something to make it stack bins too right? just the normal chip burning within tunerpro wont automatically stack bins will it?

Correct. In TunerPro, go to Tools -> Bin Stacker/Splitter. Then just tell the tool what size your BIN is, what size your chip is, what size the blocks are (I've always just set that to the same as the chip size), specify an output file, use the 'browse' button in the bottom pane to select the bin you're going to stack, then click stack. That should do it.

no the burn2 does not come with its own software, it is however designed to work in conjunction with tunerpro rt and within tunerpro there is a tab labeled tools, > Hardware Utilities, > Moates Prom I/O, and then there is were you do the stuff. I guess that is the moates software but its actually within tunerpro.

is there a way to dump the bin files over the ALDL cable with tunerpro or do i need to find and download flash hack?
Also its probably worth noting that the 7427 is not the original computer to my truck and i am still running the original sized 4K bin files not 64K bin files

Oh, it doesn't come with software? That's incredibly unfortunate. I'm sure that properly configured TunerPro RT could do it, but I don't use TunerPro RT to burn chips so I'm afraid I can't help you there.

You will want Flashhack to dump a BIN over ALDL.

just make sure you change all the things in the parameters page in flashhack or you'll get nowhere.

this tool was so simple it's crazy that nobody made it before
