With the addition of the 98s, is there any change to the autotuning process or steps? Do the 98s have the ability to do ALL of the steps and processes listed in "Autotuning"?

I was wondering this also.Quote:

Auto tune compares commanded vs actual and the difference is your BEN value. (% error)
Which you can then multiply the actual by in order for it to match commanded. (adjustment)
Therefore at WOT you can command 12.5:1 if you like in B3647 with OS3.
However if you are runinng a stock OS you must disable PE mode as per the autotune instructions, you will see B3605 for open loop has enrichment for high MAP rates. So you should be pretty safe anyway.
Its not hugely important that you are tuning to 14.63 but what is important is that your commanded and actual values are accurately compared.
DFCO, PE and often lean cruise can make this less accurate, hence they are turned off.
thanks,
The commanded is always 14.63 for me, i have noticed in some of the higher maps at low rpms that it is actually 16.xx.
I have a stock OS.
In the B3605 "commanded fuel when in open loop" table.
I set it like it says in the AutoVE of 1.13 (12.95afr) at 75map and higher at 40c and higher, but when i do my logging and look at it afterwards it says the commanded is 16.58.
why isnt it 12.95??
thanks

Im hoping somebody can help with this.Quote:

why would mine be going the wrong way? and if thats the case, i wonder if thats one of the reasons why im lean on cold starts, cuz that would be me in the 17.'s at cold idle 1.17*14.63=17.12
ADDED:
I went to the Edit>Properties>Display and changed lamda to AFR and then went back and looked at the table and sure enough, it says 16.58 instead of 12.95.
please help
thanks
Lambda and EQ are opposites of each other (inverse!), I think this has been answered by Blacky in another thread. Best idea for me anyway is to use AFR in all fueling tables as its less confusing.
if you want an AFR of 14.63 you set your PE based on rpm table to 1.00
here is an attached excel sheet of some AFR's for ya, its a zip file but if you can't unzip it send me your email address
EQ = 1/Lambda = Stoich/AFR
Rich: EQ > 1 or Lambda < 1 or AFR < Stoich
Lean: EQ < 1 or Lambda > 1 or AFR > Stoich
It can be easy to work with EQ; for example, EQ 1.02 is the same as saying 2% rich.
My PE based on RPM is set to this:Quote:

That is Stoich for my turbo setup. Does that help? Once you are in PE, the A/F goes by this table. If I wanted it 14.6, I'd simply set it at 14.6 but I need RICH when I go PE (WOT).
Elmer
im getting my turbo installed next week and ill shoot for those numbers in the pe. but what are you doing for part throttle? are you still shotting for 14.63 at part throttle?Quote:

Hi Builtyodas,
welcome to the forum :cheers:
are you running a MAF...?
Post your current tune file, and the stock 5.3 tnue file.
Joe car I sent you an email also if you could help me greatly appreciated running out of time to get this truck done
I was going to load a custom operating system and go mafless after I get the idle and thing tuned. Just trying to get it drivable so I can take it to get it tuned. It's a 5.3 with flat top pistons and an Asa cam with 36 lb Bosch injectors out of a Camaro. I've already set up the ifr tables and it runs some what but very rich and when warms up does. But driving a short distance it stays running till come to a stop
I do not have one that's my only email. Hmmm do you have messenger or another way of communication?
You could post it here if it's ok with you (other people would also comment on your tune).

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?
