ok i put craigs g2 adapter in my 747 ecm and i am running the 29c256 chips i put my stock bin in and the check engin light flashes like a strobe light. the truck will start but the light just keeps flashing what did i do wrong. this thing is my only way to get to work and i am about to just cry please help me guys

 

you are using a 32k chip, but only a 4k .bin.
You can write the 4k to the correct part of the eprom, or the easiest way is just to 'stack' you bin 8 times to fill the chip.
Tunerpro has a function to do this under 'tools'.

 

so i need to stack the bin on it. is there another way i tryed burning it to $7000-7fff with no luck i am just pissed that my baby isnt runing right

 

stack the bin. if you are using tunerpro, set the bin size to 4k, the chip size to 32k and the block size to 4k. that will give you options to enter 8 bins (0-7). the new bin it creates should work just fine.

you will also get the flashing SES light, if you chip is in backwards, or not seated properly. or any other reason for a data error.

 

stacking it solved the problem i am so happy
thank you guys
