Question: Is there a way to edit the low range switch parameters? I am putting a 00' 5.3l LXS with a 4l60E into my 92' jeep wrangler and have changed the transfer case over to a manual one. I still have the VSS on the out put of the transfer case so i need the pcm to be able to adjust the speed for when it is low range so it will shift right. I am putting a switch on pin C2-16 to tell the pcm its in low range and the transfer case is the same gear ratio as the stock one so it should work. But I am wondering if there are any parameters at all for the low range, would like to be able to adjust the gear ratio in the pcm so when I change it in the transfercase the shift points still work right. Would work nice for the rock crawling rigs. worse comes to worse I could use the performance mode and change the shift points for low range.
