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.Originally Posted by eboggs_jkvl
I also have a few other questions.
On the autoVE tuning, we are basicly getting all the cells to be 0 which will be at 14.63 AFR, correct? and what about WOT, are we suppose to hit the higher maps and get those at 14.63 also? and then do WOT tuning thru the Pe vs. RPM table after Autove is done?

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.Originally Posted by jnorris
If you take the 1.00 which is 14.63 and times it by the 1.13 you get 16.53 (16.58 acutally) which is what its commanding at those higher maps.
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.
