i've got three chips

one is a 29c that has a known good map on it (the bbka track bin) in case something goes wrong and I need it. Better safe than sorry, I keep that one in my glovebox.

the other two are SST chips, I rotate them. Keep one in the ECU, one in the burner.

If you make the power swtching daughterboard (plans are on PGMFI) you can put two programs on one chip, and literally switch between them.

..street tun.. race tune.. (On the 512K chips, that is..)
