Has anyone tried changing the rpm scale on VE1 to 200?
Did it help much?
This might be of more use to people with a 3 spd & or bigger cams.
I know I don't get max cruise vac until 2400rpm so I was just thinking.
It's pretty simple to do in the code.
Once you figure out how.
Makes it real easy to stretch out the map scale to 17 also.
Just a BRA.
Would swapping to rpm/12.5 help too?
I was too tired after I got the two tables and the l/u straight
and didn't want to see if it would help or hurt.

I've found using 400 through 2000 RPM by 100 RPM increments is nice. Then a second table that is 2000 through 6400 RPM with staggered RPM increments works out (2000 - 3600 by 200, 3600 - 6400 by 400).
The $8D stuff already has a low speed VE table by 100 RPM increments. Which mask are you working on?
8D aujp currently.
Will need to switch to $58 in a year or so.
Need to complete the 58 hac a lot more 1st.
Very little info in the algo portion. Grumpy doesn't like spoons.....
There is a lot more info on 8D so I'm using it to learn on.
If you use the VE1 & VE2 table space, then 200 rpm fits nicely. Then just shorten the extended table you patched.
And make it 7? x 14 maybe.
I just started/finished looking at this and the rpm/12.5 came to me at the end of the day.
I was looking for a relatively easy fix that is limited to just changing a few op codes around. Make's it real easy for the people that aren't too interested in code.
They actually use/work on their car instead of the code stuff like I do And I think small spoons are more effective at furthering 8D.
I need to see if there is enough room at the current VE L/U location for 3 different scales. The easy way.
I haven't made aujp relocatable yet. Lots o labels in the algo. Not bad in the cal. It's still a little beyond me. though. The Bua relocatable didn't seem all that relocatable to me at first glance. Or I am making it more involved than need be. Seems to me that the dis.exe uses all those labels to figure it out. They might not all be needed to get it to asm?
I don't spend much time between 1100 and 1650 rpm with my current 3spd/2k stall. Mostly idle or in the 1800 to 2800 range. And my setup isn't that common with 3.08's and a 243 @ 050 solid. Don't see the point in using 100 rpm out to 1600 when only stock type cars spend any time there. That's why I was asking. I don't mind testing, just my particular engines aren't well suited to that range.
So apparently you don't run into the 255 limit using 100 rpm out to 2k? Or does the /12.5 fix that?
I know 2k is 255, but you only go to 1975 using /25 then swap to VEx. Not too sure what can happen when you start bumping up against the 255 limit is all. Well I guess you could but an FF limit in there. But then you need a relocatable bin. Or can you put code in the cal region?
Would a jsr/rts would work fine?
? from above are:
1. Labels for relocatable?
2. 255 limit in 100 rpm scale?
3. code in cal region?
Starting at 400 RPM and ending at 2,000 RPM by 100's is a 17 row table. Have the table overrun the VE2 table and re-locate the VE2 table to an open area. Setup both VE tables to the same MAP break points for ease of coding. Plenty of room for table space.
Not required in $8D, but can create new RPM variables with different scaling as needed.

while i agree grumpy doesnt like spoons ever tried to eat a bowl of soup without one. if somebody had it and wouldnt share youd be pretty pissed off and fustrated when all you needed was a spoon.
Thanks RBob.
I'll try and figure out the 2000-3600 code too.
While I'm grateful for what was put out.
It strikes me as half a small spoon that required a lot of effort all the same to create.
edit: I'm refering to the $58 src release.
I look at it from the code stand point and it's limited use to me.
You'd be amazed at all the time JP86SS has into the aujp hac.
Hence the half a spoon comment.
But now I realise that I'm in the minority.
The 58 src is a great resource for people that just want to tune.
A much larger group than the "code people".
Finally got around to finishing up evrything I wanted on this.
Tested on the bench fine.
Should be tested on a running vehicle soon.
This is for aujp only , so if you use it on something else, it may not work. Somebody already tried.......and failed.(bench test)
Stupid notepad messed up my spacing...

I feel like I'm using a fork!
If anybody would like the "not ready for prime time" version, send me an e-mail. It's still kind of ugly but I'm working on it. I want it to compile before posting it up and it just won't cooperate.
Resistance is futile!
And I think small spoons are more effective at furthering 8D.
