Ok i finally bought all the stuff to burn my own chips and i have been able to get in dialed decently for it being my first time doing this. But, since i have gotten all of my stuff and started to do this i have been having trouble with the check engine light coming on sometimes it flickers very fast(burned incorrectly or installed worng?) but the thing is i will put the chip in and it will run fine a few times for hours a few times for minutes then my check engine light will come on and off and flicker and go crazy. Everythign seems to be tight and well in place i am going crazy. Also i am using a g2 adapter a zif and 27sf512 chips.

 

Have you tried bypassing the ZIF? Putting the chip directly into the G2 adapter? Also, is it programmed on the chip addressing from F000-FFFF?

 

Mine did the same after my soldering in of socket to the board. (MY soldering skills sux)

It's probably loose somewhere.

 

yeah it basically acts like its loose right now i m rechecking all the solder joints because i had a friend try tweeking how it all sat in there and if he pushed it the right way it ran fine so i m gonan give it a try two of the joints looked like i forgot to solder(i was really happy to get all my stuff in).

 

If the prom is backwards on the 8746' ecms, i know for a fact that the ses light will flash real fast. Ask me how i know.

 

Tried bypassing the ziff and with or without it i have found that the only way it runs correctly is if i havfe a buddy push down on the chip or put a piece of duct tape on to push it down tight. What should i do?

 

Clean up your solder joints (or de-solder and re-solder the assembly). Do all of this carefully.

 

I have gotten it all worked out thanks for the help.
