Hello all.

I have an 86 trans am 305 4bbl. I'm in the middle of a rebuild and will need to make some changes to the ECM prom. I no longer have a air pump or an EGR, I put a lower temp thermostat and switch in, and a 256 comp cam with 1.6 rockers.

So I pulled the ecm prom and am trying to find a match to play with. the chip has 24 pins and reads CE1090N 519k 8549 5068 06630 Delco. I have tried cross referencing it at Digikey, newport and a few others, with no success.

Can anyone help me?

It's a 2716. aka, 2716A, 27C16.

 

thank you soooooo much!

I'm sure once I screw everything up to the point of no return you will see me crying on the forum again.

Well that didn't take long! It would seem that I was able to blank the chip before saving a copy of it.

Looks like I can reed it, make changes, and save the changes. So can anyone help me with locating an origanal bin for this e-prom?

 

Please someone save me!!!

I beg for bin
