S_AUJP MAT question.
is there a mat map i'm missing somewhere? i've searched item finder and only see mat compensation counts vs mat. which makes no sense to me lol and mat inverse term lookup delta mult vs airflow. i've searched s_aujp mat here and nothing came back.
i ask because i'm turning on a fresh motor, have everything i can think of turned off by enable temp set to max and am working on my ve tables. the car gets up to coolant temp quickly and doesn't seem to very much once around 180*F but the MAT temp seems to have a large effect. once its up around 40*C(100F i think) my idle AF and cruise are mid 14s, but when the MAT is colder its much richer. like low 12s around 30*C and then it leans up when it gets warm.
any thoughts?

Re: S_AUJP MAT question.
i sware i looked thru the titles for mat. guess i'll have to read thru it for real..
thanks Rbob
looks like i've got some reading to do since my wideband input i just wired in doesn't seem to be showing up where i thought it should.
----------
wow i fail at looking...

Re: S_AUJP MAT question.
I have a question about this statement... I have everything disabled thinking I would tune the open loop ve tables to 14.7 everywhere first. then enable one thing at a time and tune the modifier so it was back to 14.7 again. after reading this I turned the egr on just to see what would happen and my 128 blms when to 118 and a item search I didn't see a pw vrs egr type of table to get them back to 128. so what's the best way to go about tuning a car with egr. should it be enabled while doing my first openloop tuning? thanks for any thoughts.
First, I have found the EGR has a profound effect on how this calculation works, so if you want to make the calculation as "consistent" as possible, you should adjust the "EGR Enable temperature" as soon as possible if you have an EGR - use x'05'. If you don't have an EGR, don't enable the EGR but putting x'FF' in the enable temperature.
