I'm running a 1227730, with a NB O2 sensor, and my own modified BIN. Is there any benefit to going to the s_aujp v4?

 

in my opinion, yes.
a few things i can think of off the top of my head.
you can set it up to use Z69's extended upper VE table & you get much better resolution, from 1600 to 3200 RPM it increases by 200 RPM instead of 400 RPM. from 3200 to 6400 it increases by 400 RPM.
map increases by 5 kpa from 20 to 100 kpa.
if you get a wideband, you can input it to the data stream for logging with minor changes to the ECM.
i haven't had a chance to play with it, but it looks like there is a useable open loop idle qualifier in it.
there are also more things defined in V4.

if you do try V4, there are 2 separate files at moates you need to get. be certain to read all the documents for it, there are a good many changes.

 

As soon as I get energetic enough to start modifying again. I guess I'd have to paste all my spark and fuel tables over eh? I'd better be energetic to get that going.

 

I'm running super AUJP 4 with AXCN tables and I noticed much better drive-ability with my 6 speed. Before it would infrequently drop idle very low and almost stall with the clutch in. Runs much smoother now.
DO IT!

 

I haven't played with my autoprom and bins for probably a year.
I downloaded the two *.zip files from Moates.net....
What is it that I have here? I found an ADS file and a XDF file, and a BIN...ok, that's easy enough. I just need a little guidance to get going. anything special here? or do I just do the "difference tool" action to modify my own BIN?

 

you want to use all 3 together.
i could easily be wrong, but i don't think compare will work quite right between a stock bin & V4. besides the stuff that has been added, i believe there are some things that have been moved in V4 vs the stock bin & the other S_AUJP bins.
if you want to use Z69's hi-res extended VE table, you must check the box for it in Flags/Switches. there is another box if you want to use his extended PE table.
i don't know how well copy & paste would work for transferring the VE & spark tables from you old bin into V4. i manually entered them in mine.

also, get the latest version of ScannerPro & load JP's files for it.

 

I quit playing around for a few months and things go right by me!! Couple more questions:


"also, get the latest version of ScannerPro & load JP's files for it."

OK, what is ScannerPro? Do I need it for my Autoprom? and, what are "JP's files"....

 

I'm going to try and see how it runs on the original settings on my stock RamJet 350. All I did was turn off VATS, set it for a Manual Tranny, set the Launch Retard flag, and set the Extended Z69 VE Table...
I guess I'll find out tomorrow how it does...

 

What is the advantage of a open loop idle

 

I did end up setting the idle vs. temp to a minimum of 700 rpm...600 rpm is just a little low for my manual tranny ramjet 350. What rpm did the manual stock '730 cars idle at? It seemed to idle ok at 600 rpm, but as soon as I moved, let go of the gas, it died a couple of times.

I also would like to know the benefit to open-loop idle? Mine is idling quite well, but every once in a while it wants does some surging.

Another question: Why are there 2 BLM parameters monitored? There's a BLM FINE and a BLM MAIN.....the "BLM MAIN" is the one that appears to match the old value in my old generic 730/8D BIN and associated ADS & XDF.

 

open loop idle is mainly for the guys with big cams.
the bigger the cam is, the more the ECM will have problems trying to correct the fuel mixture at idle. if you have a thumper for a cam, you can pretty much forget about the ECM controlling fuel at idle. my cam is stock so i don't really need it, but its nice to have.

i have a 5.7 & have never messed with any of the standard 5.0 bins, so i don't know what they idled at.

i don't have an answer for the BLM FINE, i would guess its another piece of info to help in tuning.
maybe JP or Z69 has a better answer & can shed some light on it.

 

I would like to know also

 

I didn't really do anything to begin with but turn off VATS.

Hopefully someone will share info on the BLM MAIN & BLM FINE question.

My BLM MAIN at idle is at 96. The engine runs really well considering that I haven't adjust anything but the idle vs temp parameter. Now for the long arduous process of getting everything close to 128.

I noticed that there are multiple options for a WB O2 Sensor. Is there a "preferred" WB O2 Sensor for this BIN? Something that may function better?

 

The WB code was added to allow any of the units listed to be run. None are considered better by the code. Just a way to scale each of the default outputs to end up with 10 to 20 AFR readings.

The BLM "fine" is part of the stock $8D code, its not something added in the S_AUJP.
The Value is used as a multiplier of the Main BLM that generates thevalue that is actually subtracted from the BPW. The Fine adjust is derived by calculations from air flow and proportional gains.
I'm not real clear on it but thats what I see from looking at it quickly.

The "launch mode" doesn't function for some reason so don't waste fuel on it.
I'm hopeing to get some time soon to dig into it and see what I did. I find no ill effects from it in my car or on the bench, just doesn't retard timing like it was supposed to. Soemthing else to figure out.

The OL idle is nice if you just can't get good vacuum or fuel distribution at idle when closed loop is active. Can set it so when you come to a stop your idle can be "manually" setup to run smooth without the BLM adjusting it constantly richer.
HTH

 

Could you elaborate on the tables you used. Many would like to solve that problem. There is not much in the way of documentation in that area.
TIA,

 

just to faclilitate the switchover to S_AUJPv4 with my existing setup, how do I set it to use the factory stock O2 sensor?

I didn't see anything that looked like stock O2 sensor under the options.

or, does S_AUJPv4 have to be used with a WBO2 sensor?

thanks.

 

there is nothing to change to use the stock O2 sensor in V4.
the talk about using a wideband with V4 is for data logging it in TunerPro.
if you use a wideband & don't have a NB O2, then you have to use the NB output on the WB controller to the NB input on the ECM.

 

Car ran as well as it has since I started play with chip burning. And that's without adjusting the VE tables. I was tweaking a chip last night....gonna go put it in as soon as it gets a little warmer around here. I'll try to get in a long drive and record it all....

 

I'm trying to figure out how to do the TCC Coast Release Disable in S_AUJP V4. it's currently set to E255. what do I set it to, to disable the TCC Coast Release? "0101"?

I've set my AUJP V3 to disable the coast release and I'd like to keep that feature.

sorry, I just scrolled down far enough in the documentation PDF to find it.

my apologies.

 

Another question: Why are there 2 BLM parameters monitored? There's a BLM FINE and a BLM MAIN.....the "BLM MAIN" is the one that appears to match the old value in my old generic 730/8D BIN and associated ADS & XDF.

Where in the bin do you find these or are they labled
different

 

From up above a few posts.

 

I can't find main or fine block learn in the bin,
where is it

 

I just switched over from S_AUJP V3 to V4. it works so fine. it also seems to have solved the high idle issue that I never quite licked yet, more testing to confirm that. I'm pleased. honestly appreciate the hard work that a lot of folks put into this endeavor.

 

Wow, after reading this, it seems like I may as well just go ahead and change over from a regular AUJP to S_AUJP... it sounds almost like the magic bin!

With a bunch of help from JP, Hank, and several other folks, I've got my Plymouth running and driving well enough to datalog, but I've got some trouble at part-throttle cruise that I'm having trouble sorting out. My concern is that I don't have enough of the OEM "features" turned off and they're somehow affecting my cruise. Will S_AUJP V4 be set up out of the box with the "features" (basically everything but the stuff necessary to run the engine) turned off, or will it be about the same as stock in this respect? What I'm trying to do is determine if my cruise problems are ECM/tune related, or a problem with the fuel / spark systems.

Any advice towards how S_AUJP V4 is delivered, or how to turn off the extras in the regular AUJP would be greatly appreciated. My 2.5 yr-old loves to help me tinker on the "brooom-brooom" car, but I can't get much tuning done on a regular basis when he's around. The Plymouth has been mostly dormant since last June, but I'm wanting to get her running well enough to go to a local car show in 3 weeks. Not looking for perfection, just an improvement.

Thanks in advance,

Clair

 

....than the BIN I was playing with for the last couple of years.
Changes I made on my S-aujpV4:
Turned off VATS
Adjusted Inj to 24# vs 22#(amazing)
tied in my wbO2, monitoring/datalogging.
Set it for Manual Tranny
and some minor tweaking of VE table(so minor I can't even find which cell I made the change in...I suppose I could keep looking)
OUTSIDE the BIN:
I ensured that my timing was set to 6 degrees....

The only issue I have left is a surge at idle which I'm suspecting has something to do with my IAC...have NOT played with it...and it only happens sometimes.

 

Is there a switch for manual trans or do you just have to change the constants and tables to work with a manual trans?

 

At location 18 on the item summary list, entitled:
Option Word 3 - Bit 2 - Manual/Auto Transmission Select

 

Thanks. If I'm setting the Auto/Manual flag in TunerPro, do I want that flag set or not set for manual?

 

....I figured that AUJP was for an automatic, and it came "unset", so I "checked" it to "set" it.

I am not sure that is correct(?), but there's a lot of folks around here that are much more knowledgeable than I, and I'm sure someone will let me know if I assumed wrong.

 

S-AUJP definately could not hurt. The calibration that came with it is for a mildly cammed TPI 350. The wilder the cam gets the more trouble you will have dialing in part-throttle. Overlap starts playing with both the MAP and 02 sensor.

I also notice that you have a 4spd car. The S-AUJP .bin is setup for an Automatic, but can be changed over for a stick fairly easily. Alot of things are different between an Auto calibration and a Stick. IAC routines are the big thing.

Do you have your timing controlled by the 7730 or is it off of a mechanical distributer?

What about a knock sensor, is your engine equipped with one?

What about a vehicle speed sensor?

Its hard to determine what the problem maybe, without all the information.

 

Correct, You should select the type of trans you have.
There are a few tweaks in the code to make the IAC work better with the MT when selected. There are several tables that could benifit from using the MT bins values to make everything good.
I don't have a MT so do not have any solid info on which values work better.

 

So should the flag be set or un-set for manual? What actually happens when you change it to manual? Does it ignore all the auto stuff like TCC, 4th gear switch, etc?

 

"F2" in TP will open the item editor where there are notes on most of the functions and what they do.
"b2, Manual/Auto Transmission Select. On=Manual Off=Auto"
Yes, it will bypass all of the TCC stuff, not sure on the 4th gear switch.
Would have to look into that, IDK if any of the MTs have a high gear switch.

 

Thanks JP86SS; I've been using TunerproRT for a couple of years and I didn't know that thing about F2.

 

Ditto on the F2 notes, I need all the explanation I can get in my infrequent efforts, and that will be a big help. Thanks again, JP!

Fast355,
Thanks for the reply. To answer your questions:

The OEM calibration for the AUJP seems to be pretty radically different than what my engine likes, at least judging by the comparisons I've made to my tune over time. The GM engineers really did their job tuning those engines, and the TPI intake really boosts the midrange VE where mine is quite a bit softer - thanks to the short runners on my single plane intake. Cam is pretty mild, a Crane HMV272 that pulls 17" of vacuum @ 800rpm. CR is a smidge over 8:1.

I *BELIEVE* that I've got my .bin set up for the 4-speed, but I need to make the F2 check ASAP. So far, the IAC function seems OK. I've got my minimum idle speed set at the TB, but cold-starts are still handled by the IAC.

I tried running my car on some stick tunes (AXXC, etc), and it wouldn't play well for some reason. CEL/SES was on steady from the moment I fired it up, so I went back to what I knew.

Ignition is all ECM. My timing is fairly mild at this point because I didn't want to introduce any extra weirdness this early in the game.

No knock sensor at this point, but I'm planning on using a 350 unit after I get everything else sorted out. Not a priority at this point.

VSS is present and functional.

I agree that diagnosing an unknown combo via the internet sucks, especially something like "it isn't smooth in the midrange". I think before I get in to a "what's wrong with my tune" thread, I'll try out S_AUJP v4 and see how it does. At this point, I don't see how I can go wrong.

BTW, since you're local, I may see about picking your brain by PM one of these days... Seems like there are several folks in the Metroplex that know their stuff...

Other than the manual/auto flag (option word 3, bit 2) there's also a manual option scalar set to zero. AXXD (manual bin) is set to 1 but the F2 info says to set it to anything less than zero for manual. Do I need to mess with this? Thanks.

 

I see that value at address $8671 and all I have is a note that indicates
"any value except 0 = manual trans"
I do not find anywhere in the code this address is used in AUJP/ANHT so I don't think it will do anything. (There could be an indexed addressing call that I missed when searching the code for the address)
Just the Auto/Manual flag should do it because that is wht Z69's modifications look at.
Try changing it and post up if anything changes.

 

JP, as you suspected it is an indexed value. Here is where it is used:

RBob.

 

for a manual transmission?

0? or something else?

I'm sorta confused after the last 3 messages?

 

Set anything except "0" for Manual. (Make it = 1)

Thanks Rbob for pointing that out.
As usual your knowledge of the code astounds me

I have some more studying to do on this whole Man/Auto stuff.

 

...but, should it even matter if the Manual/Auto flag "checked" for manual???

 

Yes, some of the stock and added code for the IAC operation checks that bit.

 

F2 doesn't do anything for me... What am I doing wrong?

 

first highlight an item in constants, flags or tables & then hit F2. it does the same thing if you right click an item in any of those & select Edit Item XDF Info.

 

what the heck?



and what should I do about those ?????'s?

 

Just re-reading this whole thread again and looking at _v4. I think the resolution enough would be reason enough for me to switch....IF, it had some of the forced induction functionality in it like $59....(that was my attempt at a subtle hint at putting it in!). Great work on this release, honestly. I wish I could use it.

 

Nothing, its just a text lable.
I did just notice the description indicates < 0 instead of > "greater" than 0.

 

now I'm confused?
What should it be?
+1 or -1?

 

I'd almost wager that a negative number is meaningless in this situation. The description should probably be "zero" or "not zero" rather than < or >.

Clair

 

Yup!
Would have made it easier.
