I've read this tuning AE article https://www.thirdgen.org/techbb2/sho...hreadid=195745 for 7730 but the table names are different in SAUJPv4 and I'm trying to find the table that affects AE globally. The table was called "accel enrich delta tps multiplier vs delta tps" in the article. Does anyone know what the saujpv4 equivalent is? Thanks.

 

I think you are looking for AE, Async Factor vs Delta TPS

 

Thanks for the response. That's the table I was working with but I wasn't sure if it was the right one. My AFR's dip to 10:1 for an instance when I mash the throttle while going down the road. Does anyone know if that's normal?

 

I see the same thing with the TPS changing by more then 4-5%. I've been wondering if that's normal also. I currently run the stock values. I've been wondering if the larger injectors need a little less PW during pumpshot.

 

Does anyone else experience this?

Well with all the tinkering I've been doing I had a chance to drop some of the lower table entries by 5%. What I noticed with my heated NB is that where I would normally hit 800+ mV I now was hitting about 700 mV. I might try another 5% in the lower range to see how it feels. I can't say that I feel a performance difference but there wasn't any increase in knock counts. I would imagine that a huge spike in the O2 at the lower TPS range makes it a little tougher to tune from a data log. I don't think it's as big of a deal if your just cruising along real slow and then go 50% on the go pedal. I can understand hitting 800 mV. But just cruising along and applying a little pedal to increase your MPH by a few digits doesn't make sense to hit 800+ mV. But also I have been reading up on O2 stuff. Apparently with a modified motor the O2 correction can overshoot the upper window target and shoot the mV up too. I'm gonna try to tighten that up a little as well.

 

You may also want to tweak you IAC throttle follower too.
That can play a big role when moving the throttle.
I chased a lean spike and could not get AE enough to cover it but by reducing the TF it got better and I had too much AE.
Not saying to use that as the tool but something to see if it helps.

 

Which IAC TF table did you modify?

 

There is a throttle follower under the constants. I believe the default in S-AUJP is about 39% or at least that is what I am using.

 

I'm using S_AUJP V4 and the only constant I see regarding percentage is the tf slope gain which mine is set to 100%. Is this the one?

 

That is the one. There is also a max steps and a max steps in drive too.

 

What exactly does the TF slope gain constant do anyway? TF max steps is set to 160,

 

This should explain what it does better then I could.
