hey guys new here and need some help. i installed a vortec 5.7 into a 98 s10 along with a 0411 pcm. we have been trying to figure this out for some time. when truck first starts cold it runs very good maybe a little smoke from fuel im guessing. after it warms it starts to smoke of fuel badley. should i follow the auto tune post above or am i missing something. i am trying to run a 2002 express file for the tune. thank you in advance for any assistance you can provide. by the way i have efi for this build but am not very savy on tuning.
so went through auto tune instructions but i do not have a wideband. i did notice right side o2 reading higher voltage than left. engine runs great with throttle but terrible at idle. i messed with ve tables today lowering them which seemed to help smoke but had a hard time idling. any help is appreciated.
You can get by without having to edit B3605... it's values will show up on the wideband.
Thank you for the responses! I did find the help tutorial that talked about B3647 vs B3605 so I think I am good with that part.
Now I just have to set up the correct PIDs. I guess I have to create a custom PID for my AEM UEGO? I am surprised it is not an option. Or am I missing it?
I am trying to create the Serial PID Base Efficiency Numerator - External WO2LAM1_LS1. The instructions do not say what to do with the file once you complete it? Just click save? I have attached the calc_PIDs.txt. Did I do something wrong here?
Thanks!Attachment 23276
OK I finally figured out the PIDs. Now when I try to connect I get the following error. Can V7.5 still be used somehow?
