Reading / Writing Stock VS EPROM

Post by ev351 »

Hi all, and thanks for the help so far.

I have a VS v6 Supercharged ECU, which I was all ready to remove the VATS on (Thanks to Delcowizzid and Antus) but to my dissapointment, I find that the PROM cannot be removed from that silly holder. I saw a home brew solution on here which I like the idea of, and I may be hacking into some old PC motherboards on the weekend so that I can make an adapter from the memcal to the EPROM burner.

My question is, what brand is the stock PROM, the numbers on it do not make sense. Are they just a 27c010, or something slightly different? and can i just erase and reprogram as a 27c010? What is the PGM voltage?

Thanks.

Just use the settings for a generic 27c010 with 12.5v for the program voltage. Burn the bin with offset 0.
