paste and divide...?

[mr.prick]

how do i make a PID so i can divide by BEN factor for the RR.
i believe that {3632} can be changed by lowering the value with BEN.
i have tried using BEN with the RR and it
increases the value, leaning out the AFR.
if i can just get this table right i think my cold start fueling will get inline.
feel free to correct me if i`m wrong.

you don`t want this number to increase,
so i figured that if you can change it the opposite of the way
BEN factor does then you can get the right value.
at least this is my understanding of it.
as for the desired AFR i am not to sure if is for idle only
or if it is for the whole {B3605} commanded fuel in open loop table.
i will try your spreadsheet in the morning,
thanks

I think the final result changes whatever the car would normally command so it probably stacks on top of PE too.

All I know is that this value is subtracted from whatever the car is commanding so you have to approach it differently.

yes,
this is why i want to change with BEN factor (divide)
i am using the RR so i know for a fact that if this increases it leans.LOL
so if i can decrease with BEN i am pretty sure it will work out
can you edit that spreadsheet to where i can put in the stock table values
and then use BEN to divide?
or can someone tell me how to make a PID that will decrease by BEN.

So anytime you entered positive numbers the car went lean and negative numbers make the car rich?

I just tried it in my car and positive numbers made it go rich and negative made it go lean. But I dont have an RR so the car was getting warmer with each trial.

yes when i changed this table with BEN factor it leaned out.(higher values)
if you look the values are larger with lower ECT.
stock commanded AFR is rich then leans as you get higher ECTs.
so this value decreases as the motor warms up. (subtracting less)
this value is subtracted from OL commanded value.
bottom line is i changed it with BEN it leaned and i am hoping to get someone to tell me how to make a reverse BEN PID and try that.
i could do it manually but i would like to use the RR so as to use
RTACS to confirm my belief.
BTW
14.63 = 1.00 BEN (in my OS)

To make the pid reversed you only need to change the equation around.
Calc ben is Actual/commanded. Make a pid that is commanded/actual.
