Modded ECM Install

[czimpel]

Installing my modded ECM and TT chip for 120lb injectors today and noticed that my stock ECM has a second smaller chip as well as the main chip. My modded ECM has the slot open on the smaller chip.

Do I replace the small chip into the modded ECM?

move the smaller chip over to the modded ECM. Its the limp-home chip.

Thanks for the help Bob.

Ya, the limp home chip needs to be there to prevent a code being set, but.....Isn't going to be much help if the ECM ever drops into limp home mode with those injectors installed !
