anyways to my point. i've been doing a lot of research on the 0411 pcm and 24x efi connection stuff. and i'm trying to decide the best route to go. i have never tuned or seen a gm pcm get tuned before. this car is my daily for the most part but i drive a work vehicle for at least a week at a time if not more if i wanted to. so what im trying to accomplish is a budget minded build to swap mpfi and to a 0411 pcm at the same time that i can maybe accomplish in a few weeks once i get everything together
i know the l05 is lacking in performance part and the swirl port heads "aren't great" but i'd like to at least convert the system first and then upgrade as i see fit. I don't want to ls swap because there's too much work for my liking to swap this car lol
so i understand the items i need for the 0411 pcm swap, i plan on junkyarding for most items.
heres my plan
L05 (in car)
LT1 cam (free from a friend)
0411 pcm/harness from a friend of mine from a 4.8 truck($100ish)
already have truck coil packs so id like to do cnp first round but wouldn't mind distributor still(paid 70 bucks)
vortec parts (cover/balancer/1x distributor/4x reluctor wheel (just in case)/ knock sensor/ 4 wire o2's) ($150ish)
tpi intake from jy ($40)
lt1 24lb injectors
keep the 4l60 for now so ill try a tpi tv cable , until i can score a 96+ 4l60e after i get it running with the new setup
efi connection 24x wheel and 24x sensor (250 or whatever it is now)
Anyways my main concerns:
as far as pcm calibrations...do i really have to spend $800 on efi live or are there people here that can get the pcm working enough to drive to a shop for a tune? It's a 0411 pcm out of a 01 express van with a v6?
id rather spend that money on the efi connection harness if i can't manage to put one together worth a crap (i really dont like wiring but i can do it) or if anyone here would like to offer wiring capabilities that wold be awesome
this board seems to have alot of knowledge on tuning and ls gm pcms so i figured it would post here instead of a car specific for me, feel free to move this if there's a better place for it
