Default Need help with '90 Auto L98 ECM Programming

My car has 1227727 ECM in it. I have been trying to find the .ecu file for it with no luck

Also, how do I find out the Broadcast Code of my chip? There is no information on the chip itself.

Please help.

I just read the stock .bin file and it seems to be completely corrupted. Can someone please send me a stock .bin file for L98 '90 Auto???????

Time to look around in the diy-efi.org archives. Lots of bins and ecus over there. Have you read the intro to prom burning at thirdgen.org?

I finally learnt that 7730 and 7727 are the same ECUs and did download an .ecu file from diy-efi and was able to read the contents of my own chip correctly.

Now I have re-programmed my chip for 30 lbs injectors, the next challenge is how to change the AFR for WOT....WB O2 sensor seems to be the right way, however I am still researching what other alternatives might be out there....Any ideas?
