Can also command more than ~45* of timing is you want/need to. Probably not all that useful but you no longer have that physical limitation.
is anybody on here using hp tuners and willing to look over my tune for the 0411 swap? I have a 1999 K1500 suburban with a GMPP HT383E engine. I did the swap and double checked all the wiring and the truck wont start. I think it has to be either a problem with the tune or a hardware issue either with the pcm or something on the truck that happened during the swap. I have no spark at all. the truck ran with the black box, but it wont even think about starting after swap. I cant figure out what im over looking. if anybody is willing to help me out, I'll email you my file. thanks.
