I am thinking this may be a option for vortec v8's, because guys that did 0411 swaps had to use a cal from a s10 to get their 4x4 to work properly. I sent a copy of the stock that I am using now, to holdencrazy's email. It was outta a 4x4 s10 2004 with a 6243. All modules work with the swap, only thing I have noticed is the tach is off, which would prolly be corrected by getting a new cluster, but am not to concerned about that right now.
If that is the case then the v6 uses a 3x crank signal. I remeber reading that in SI. I haven't changed anything and it works with this computer. Hmmm. What tables control this? Maybe this is why my tach is off.
