Tuning a 1227727

[space387]

I have started learning how to apply my experience working with aftermarket ecu's and the LT1 EEprom system to my 90 y-body 1227727. In switching it to the S_AUJP V5 I have a few questions. First where is the darn skip shift setting? That was the first thing I tuned out of my 94 LT1 and would like to do the same here if possible. Second I am looking at a wide band system that provides a linear 10-20:1 at 0-5v what setting would be correct for reading from this? If none are listed is there a way for me to build a custom set of parameters? Thanks in advance.

Thank you. I seem to be running into another issue of either a no start or start with high idle and no 160 baud data with the corvette ccm. Is there a specific way to enable the use of higher function tunes like the use of $8D and S_UAJP? Seems that the notion os burn a chip and test isnt working as well as I hoped.

Edit: yea the issue I had was a short between the seat and the keyboard. Tuned chip is working right.
