Got my pocket programmer today and I burned two chips to see how it works. Well both chips give me a code 51, the idle is at 1500 in neutral and the speedo doesnt work. Also the SES light is constantly on. The car feels good when driving with more power than before (used a ZZ4 calibration .bin). Could I have done something wrong when programming these EPROM's ? I used option 20 in the "fileprom" program that came with the programmer to select the type of EPROM and wrote it sucessfully (the software said so anyway). Any ideas why it would this ?!

Blade,

Option 20?! You should be using option 11. Option 11 is for 27C256 chips. Double check and then let me know.

Well I typed in E first for the "EPROM choices" then another screen came up where I chose option 20...
