What is this table from S-aujpV4 telling me? It seems to vary quite a bit...

here's what it's titled in TunerproRT:
PE, % Change to AFR Vs. RPM Extended Table (Z69)

 

Its just that, an AFR multiplier for PE vs RPM.

I'm used to looking at the table in this format (try this in your conversion equation):

0.007813 * X + 0.000000

 

Its another extension of an existing table.
You will be able to control the PE adder to a higher rpm than the stock table.
(If enabled) The original table is not used and this one is substituted and used in its place.

 

...I hadn't changed it, but it looked so odd that I thought that perhaps I'd messed it up while playing my s_aujpv4 BIN.

5.7Ramjet; what BIN are you using for your Ramjet? I also have a Ramjet and I am now using the s_aujpv4.

 

I am using my own version of AUJP currently. Last I messed with it was last year and I was testing some of my own code; hence the reason I was using AUJP. I was also using my code to run open loop idle - as well as closed loop min rpm and min map, ie open loop past idle mode.

It looks like v4 might have open loop idle, but I haven't really looked at any of the documentation.

 

It does but is strictly RPM controlled.
There is an RPM that you need to drop below (to go into OL idle) and an RPM value to exceed (to go back to CL).
that way there is a differential and it doesn't keep bouncing in/out of CL.

 

I might have to give that a try when I get back to tuning...

I didn't build an rpm deadband into mine, but I didn't get to test much with it after I made the changes.

Anyhow, back to the original question.
