Im new to this and bought everything to get started. I pulled my memcal and discovered that the chip has been replaced with an unknown aftermarket one that has the stock delco sticker covering the uv opening. I have both TunerCat & TunerPro and both wont read the chip saying I need the definition file $25. So I figured if i could download the original bin that would be a good starting point. I have looked and no one seems to have that bin. Also considered going with a bin file from a 89 since im switching to a stealthram and eliminating the cold start injector. Any advice or help would be greatly appreciated

 

The akfy 305 tpi manual trans is a $32B once you have your read look at your buffer. It maybe be on a 27c256 with changed offset 16k .bin . you cannot reprogram this uv eprom on the burn 2. The $6e seems too have a little longer crank time but has a lean cruise mode. You can unsolder the uv eprom and use a moates d2 dip or solder in a 27sf512 or use the g1 and sst flash eprom.

 

btw it doesnt look like you have the header in the right place are you sure the eprom is back far enough on the burn 2 ?

 

I have it all the way to the one side of the burn 2 opposite the indent in the chip side. Isn't that correct? I posted the pix to also show that the chip does not show what it is. It doesn't have 27c128 or 27c256 like I expected. the kit from tunercats came Edith the burn 2, moates adapters, and a 27sf512 eprom. I also purchased a UV eraser and extra e proms. Looked on line thru all the links but no one had that particular bin file for download.

 

it just looked like the header was not in the correct spot in the zif not the orientation. just do a read as a 27c128 and goto the buffer and see if it shows 32 starting in 00000008-9. acdelco chips do not always label them the identifier is the 160xxx. why did you buy a uv eraser do you have another programer ?

 

btw the 32B xdf is free, but you need to read the eprom right first 000000 -> 003FFF

 

The 32b came with my tunercat as i had ordered it for my specific car. I downloaded the 32b for tunerpro from gearhead efi along with some bin files just to get a feel for what everything looks like and does. I ordered the uv eraser because i read that depending on the chips you would need it. I also have 5 brand new 27c128 chips and 5 27sf512 chips because I wasnt sure which were better or easier to use. I guess my first noobie question should have been WHY cant I read my bin file from my chip. I will have to play with it again tonight when I get home from work. I do appreciate the help

 

like I said in the earlier post you may have your start and stop wrong for the read, and you CANNOT reprogram uv eproms with the burn 2
