Re: .bin file size

Got a quetion, I had my 747 truck dyno tuned and a custom chip was made for it. The truck runs well, but I'm planning on converting some of the info from custom chip into the EBL and take the remaining issues on myself.

My question is this, why do I get 32kb file sizes? With a USB pocket programer and AT29C256 chips, 7000hex start of device. I think it's normal and ok, but just looking for reasurance before I do all this editing.

Thanks

KM

The 29C256 chip is a 32k chip, If you are just pulling the file from it, is the 4k bin stacked 8 times, to fill the chip.

If you use tuner-pro, you can you the stacker/splitter program to split it down to the 4k bin that you actualy use. Then when you modify it, just restack it back to a 32k bin to burn on the chip.
