Hello Nisanda, thank you very much for providing me with the tune file! I will study it and use it for my 411. I'm just starting to get around the tuning process, and for now studying all the info about it. Any way, thank you once again for the tune, that helps alot!!! Will start doing something, than hope to get support here, at the gearheaf-efi forum, to tune everything properly..Originally Posted by NISANDA
your welcome
Did I misunderstand? You rebuilt the TBI engine and used vortec heads and efi? So the ecm cant see the crank position and is probably operating off limp home mode?
Hello Kacy, well not exactly, i used the plastic vortec cap of a 1998 tahoe, with crank position sensor, same tahoe the heads came from.
Let me edit my post, in order to fulfill the answer: I rebuiled the L05 TBI engine, used L31 vortec heads with all the top end from vortec, meaning i installed CSFI, but changed the spider in CSFI for for the one with injectors on the ends "AC DELCO 217-3029 89060440", installed the "Comp Cam 08-467-8". Wiring from vortec and the PCM "Black Box" from Vortec engine as well 1997 or 1998 not sure, but i think 1998. Hope this makes it more clear, if not, i can make it as a list of parts i used for my build.
Regards.

Hello Nisanda,
I have used the .cal file you have uploaded for me "2001 Truck 5.7 L31 4l60e 4x2.cal" in post 57 of this thread, and i have installed a new 4L60E transmission id: 8KCD283L 20820533. Well i bumped in to a problem that my 0411 pcm doesn't seem to recognize the transmission, i have faults all over, the pwr TCC, the tcc, and oll of the solenoids that the pcm does not see, so the transmission is in the Limp mode. I have contacted the transmission guru, who rebuild my transmission, and checked all of the solenoids, all work fine, have checked the wiring that goes from the PCM to the transmission, it is all good, normally the pcm should see everything, but it doesn't, the transmission guru as well does not know why it seems not to work, he advised me to look at the firmware of the pcm, i did not find anything criminal there. May be you have some clue on my issue.
Thank you in advance.
