I have a 1990 truck with 350 tbi. It has the 1227747 with ASDU K setup for the L05 engine. I picked up a chip for $20 for a 1992 350 tbi w/ 5 spd manual since these two setups both use the 1227747 C3 and the L05. I was hoping the chip would just swap in since it looked like it should go. Instead, when I put the chip in, it blinked like it was in limp-home mode. I've done lotsa research and reading on places like diy-efi and read some tuning guides. Anyone have any ideas? Otherwise, I'm going to take the table data from the newer chip and try bringing it into the working one.
Thanks.

There are 10 kinds of people: those who know binary and those who don't
No, not the memcal, the chip itself. You may want to make your way over to TGO and ask there. www.thirdgen.org/techbb2
